SUPPLEMENTARY INFORMATION: 

Executive Summary

    Why we need to publish a rule. Under the Endangered Species Act 
(Act), any species that is determined to be threatened or endangered 
requires critical habitat to be designated, to the maximum extent 
prudent and determinable. Designations and revisions of critical 
habitat can only be completed by issuing a rule. Elsewhere in today's 
Federal Register, we propose to list the New Mexico meadow jumping 
mouse as an endangered species under the Act.
    This rule consists of: A proposed rule for designation of critical 
habitat for the New Mexico meadow jumping mouse. The New Mexico meadow 
jumping mouse has been proposed for listing under the Act. This rule 
proposes designation of critical habitat necessary for the conservation 
of the species.
    The basis for our action. Under the Endangered Species Act, any 
species that is determined to be a threatened or endangered species 
shall, to the maximum extent prudent and determinable, have habitat 
designated that is considered to be critical. Section 4(b)(2) of the 
Endangered Species Act states that the Secretary shall designate and 
make revisions to critical habitat on the basis of the best available 
scientific data after taking into consideration the economic impact, 
national security impact, and any other relevant impact of specifying 
any particular area as critical habitat. The Secretary may exclude an 
area from critical habitat if she determines that the benefits of such 
exclusion outweigh the benefits of specifying such area as part of the 
critical habitat, unless she determines, based on the best scientific 
data available, that the failure to designate such area as critical 
habitat will result in the extinction of the species. The species has 
been proposed for listing as endangered, and therefore, we also propose 
to designate approximately 310.5 km (193.1 mi) of critical habitat 
within Bernalillo, Colfax, Mora, Otero, Rio Arriba, Sandoval, and 
Socorro Counties, in New Mexico; Las Animas, Archuleta, and La Plata 
Counties, Colorado; and Greenlee and Apache Counties, Arizona.
    We are preparing an economic analysis of the proposed designations 
of critical habitat. In order to consider economic impacts, we are 
preparing a new analysis of the economic impacts of the proposed 
critical habitat designations and related factors. We will announce the 
availability of the draft economic analysis as soon as it is completed, 
at which time we will seek additional public review and comment.
    We will seek peer review. We are seeking comments from 
knowledgeable individuals with scientific expertise to review our 
analysis of the best available science and application of that science 
and to provide any additional scientific information to improve this 
proposed rule. Because we will consider all comments and information 
received during the comment period, our final determinations may differ 
from this proposal.

Information Requested

    We intend that any final action resulting from this proposed rule 
will be based on the best scientific and commercial data available and 
be as accurate and as effective as possible. Therefore, we request 
comments or information from the public, other concerned governmental 
agencies, Native American tribes, the scientific community, industry, 
or any other interested parties concerning this proposed rule. We 
particularly seek comments concerning:
    (1) The reasons why we should or should not designate habitat as 
``critical habitat'' under section 4 of the Act (16 U.S.C. 1531 et 
seq.), including whether there are threats to the species from human 
activity, the degree of which can be expected to increase due to the 
designation, and whether that increase in threats outweighs the benefit 
of designation such that the designation of critical habitat is not 
prudent.
    (2) Specific information on:

[[Page 37329]]

    (a) The amount and distribution of the New Mexico meadow jumping 
mouse and its habitat;
    (b) What may constitute ``physical or biological features essential 
to the conservation of the species,'' within the geographical range 
currently occupied by the species;
    (c) Where these features are currently found;
    (d) Whether any of these features may require special management 
considerations or protection;
    (e) What areas, that were occupied at the time of listing (or are 
currently occupied) and that contain features essential to the 
conservation of the species, should be included in the designation and 
why; and
    (f) What areas not occupied at the time of listing are essential 
for the conservation of the species and why.
    (3) Land use designations and current or planned activities in the 
areas occupied by the species or proposed to be designated as critical 
habitat, and possible impacts of these activities on this species and 
proposed critical habitat.
    (4) Information on the projected and reasonably likely impacts of 
climate change on the New Mexico meadow jumping mouse and proposed 
critical habitat.
    (5) Any foreseeable economic, national security, or other relevant 
impacts that may result from designating any area that may be included 
in the final designation. We are particularly interested in any impacts 
on small entities, and the benefits of including or excluding areas 
from the proposed designation that are subject to these impacts.
    (6) Whether our approach to designating critical habitat could be 
improved or modified in any way to provide for greater public 
participation and understanding, or to assist us in accommodating 
public concerns and comments.
    (7) The likelihood of adverse social reactions to the designation 
of critical habitat and how the consequences of such reactions, if 
likely to occur, would relate to the conservation and regulatory 
benefits of the proposed critical habitat designation.
    Please include sufficient information with your submission (such as 
scientific journal articles or other publications) to allow us to 
verify any scientific or commercial information you include.
    Please note that submissions merely stating support for or 
opposition to the action under consideration without providing 
supporting information, although noted, will not be considered in 
making a determination, as section 4(b)(1)(A) of the Act directs that 
listing and critical habitat determinations must be made ``solely on 
the basis of the best scientific and commercial data available.''
    You may submit your comments and materials concerning this proposed 
rule by one of the methods listed in the ADDRESSES section. We request 
that you send comments only by the methods described in the ADDRESSES 
section.
    If you submit information via http://www.regulations.gov, your 
entire submission--including any personal identifying information--will 
be posted on the Web site. If your submission is made via a hardcopy 
that includes personal identifying information, you may request at the 
top of your document that we withhold this information from public 
review. However, we cannot guarantee that we will be able to do so. We 
will post all hardcopy submissions on http://www.regulations.gov. 
Please include sufficient information with your comments to allow us to 
verify any scientific or commercial information you include.
    Comments and materials we receive, as well as supporting 
documentation we used in preparing this proposed rule, will be 
available for public inspection on http://www.regulations.gov, or by 
appointment, during normal business hours, at the U.S. Fish and 
Wildlife Service, New Mexico Ecological Services Field Office (see FOR 
FURTHER INFORMATION CONTACT).

Previous Federal Actions

    All previous Federal actions are described in the proposal to list 
the New Mexico meadow jumping mouse as an endangered species under the 
Act published elsewhere in today's Federal Register.

Background

    It is our intent to discuss below only those topics directly 
relevant to the proposed designation of critical habitat for the New 
Mexico meadow jumping mouse. For a thorough assessment of the species' 
biology and natural history including limiting factors and species 
resource needs, please refer to the May 2013 version of the New Mexico 
Meadow Jumping Mouse Species Status Assessment (SSA Report; Service 
2013, entire, available online at www.regulations.gov, Docket No. FWS-
R2-ES-2013-0014).

Critical Habitat

Background

    Critical habitat is defined in section 3 of the Act as:
    (1) The specific areas within the geographical area occupied by the 
species, at the time it is listed in accordance with the Act, on which 
are found those physical or biological features:
    (a) Essential to the conservation of the species and
    (b) Which may require special management considerations or 
protection; and
    (2) Specific areas outside the geographical area occupied by the 
species at the time it is listed, upon a determination that such areas 
are essential for the conservation of the species.
    Conservation, as defined under section 3 of the Act, means to use 
and the use of all methods and procedures that are necessary to bring 
an endangered or threatened species to the point at which the measures 
provided pursuant to the Act are no longer necessary. Such methods and 
procedures include, but are not limited to, all activities associated 
with scientific resources management such as research, census, law 
enforcement, habitat acquisition and maintenance, propagation, live 
trapping, and transplantation, and, in the extraordinary case where 
population pressures within a given ecosystem cannot be otherwise 
relieved, may include regulated taking.
    Critical habitat receives protection under section 7 of the Act 
through the requirement that Federal agencies ensure, in consultation 
with the Service, that any action they authorize, fund, or carry out is 
not likely to result in the destruction or adverse modification of 
critical habitat. The designation of critical habitat does not affect 
land ownership or establish a refuge, wilderness, reserve, preserve, or 
other conservation area. Such designation does not allow the government 
or public to access private lands. Such designation does not require 
implementation of restoration, recovery, or enhancement measures by 
non-Federal landowners. Where a landowner requests Federal agency 
funding or authorization for an action that may affect a listed species 
or critical habitat, the consultation requirements of section 7(a)(2) 
of the Act would apply, but even in the event of a destruction or 
adverse modification finding, the obligation of the Federal action 
agency and the landowner is not to restore or recover the species, but 
to implement reasonable and prudent alternatives to avoid destruction 
or adverse modification of critical habitat.
    Under the first prong of the Act's definition of critical habitat, 
areas within the geographical area occupied by the species at the time 
it was listed

[[Page 37330]]

are included in a critical habitat designation if they contain physical 
or biological features (1) essential to the conservation of the species 
and (2) which may require special management considerations or 
protection. For these areas, critical habitat designations identify, to 
the extent known using the best scientific and commercial data 
available, those physical or biological features that are essential to 
the conservation of the species (such as space, food, cover, and 
protected habitat). In identifying those physical and biological 
features within an area, we focus on the principal biological or 
physical constituent elements (primary constituent elements such as 
roost sites, nesting grounds, seasonal wetlands, water quality, tide, 
soil type) that are essential to the conservation of the species. 
Primary constituent elements are the specific elements of physical or 
biological features that provide for a species' life-history processes, 
and are essential to the conservation of the species.
    Under the second prong of the Act's definition of critical habitat, 
we can designate critical habitat in areas outside the geographical 
area occupied by the species at the time it is listed, upon a 
determination that such areas are essential for the conservation of the 
species. We designate critical habitat in areas outside the geographic 
area occupied by a species only when a designation limited to its range 
would be inadequate to ensure the conservation of the species.
    Section 4 of the Act requires that we designate critical habitat on 
the basis of the best scientific data available. Further, our Policy on 
Information Standards Under the Endangered Species Act (published in 
the Federal Register on July 1, 1994 (59 FR 34271)), the Information 
Quality Act (section 515 of the Treasury and General Government 
Appropriations Act for Fiscal Year 2001 (Pub. L. 106-554; H.R. 5658)), 
and our associated Information Quality Guidelines, provide criteria, 
establish procedures, and provide guidance to ensure that our decisions 
are based on the best scientific data available. They require our 
biologists, to the extent consistent with the Act and with the use of 
the best scientific data available, to use primary and original sources 
of information as the basis for recommendations to designate critical 
habitat.
    When we are determining which areas should be designated as 
critical habitat, our primary source of information is generally the 
information developed during the listing process for the species as 
reviewed in the May 2013 SSA Report (Service 2013, entire) and the 
proposed rule for listing the species as endangered (which is 
publishing simultaneously with this proposed rule in today's Federal 
Register). Additional information sources may include articles in peer-
reviewed journals, conservation plans developed by States and counties, 
scientific status surveys and studies, biological assessments, other 
unpublished materials, or experts' opinions or personal knowledge.
    Habitat is dynamic, and species may move from one area to another 
over time. We recognize that critical habitat designated at a 
particular point in time may not include all of the habitat areas that 
we may later determine are necessary for the recovery of the species. 
For these reasons, a critical habitat designation does not signal that 
habitat outside the designated area is unimportant or may not be needed 
for recovery of the species. Areas that are important to the 
conservation of the species, both inside and outside the critical 
habitat designation, will continue to be subject to: (1) Conservation 
actions implemented under section 7(a)(1) of the Act, (2) regulatory 
protections afforded by the requirement in section 7(a)(2) of the Act 
for Federal agencies to ensure their actions are not likely to 
jeopardize the continued existence of any endangered or threatened 
species, and (3) the prohibitions of section 9 of the Act if actions 
occurring in these areas may affect the species. Federally funded or 
permitted projects affecting listed species outside their designated 
critical habitat areas may still result in jeopardy findings in some 
cases. These protections and conservation tools will continue to 
contribute to recovery of this species. Similarly, critical habitat 
designations made on the basis of the best available information at the 
time of designation will not control the direction and substance of 
future recovery plans, habitat conservation plans (HCPs), or other 
species conservation planning efforts if new information available at 
the time of these planning efforts calls for a different outcome.

Prudency Determination

    Section 4(a)(3) of the Act, as amended, and implementing 
regulations (50 CFR 424.12), require that, to the maximum extent 
prudent and determinable, the Secretary designate critical habitat at 
the time the species is determined to be an endangered or threatened 
species. Our regulations (50 CFR 424.12(a)(1)) state that the 
designation of critical habitat is not prudent when one or both of the 
following situations exist: (1) The species is threatened by taking or 
other human activity, and identification of critical habitat can be 
expected to increase the degree of threat to the species, or (2) such 
designation of critical habitat would not be beneficial to the species.
    There is no documentation that the New Mexico meadow jumping mouse 
is currently threatened by collection, and mapping of critical habitat 
is not expected to initiate any such threat. In the absence of a 
finding that the designation of critical habitat would increase threats 
to a species, if there are any benefits to a critical habitat 
designation, then a prudent finding is warranted. The potential 
benefits include: (1) Triggering consultation under section 7 of the 
Act in new areas for actions in which there may be a Federal nexus 
where it would not otherwise occur because, for example, it has become 
unoccupied or the occupancy is in question; (2) focusing conservation 
activities on the most essential features and areas; (3) providing 
educational benefits to State or county governments or private 
entities; and (4) preventing people from causing inadvertent harm to 
the species. Therefore, because we have determined that the designation 
of critical habitat will not likely increase the degree of threat to 
the species, and may provide some measure of benefit, we find that 
designation of critical habitat is prudent for the New Mexico meadow 
jumping mouse.

Critical Habitat Determinability

    Having determined that designation is prudent, under section 
4(a)(3) of the Act, we must find whether critical habitat for the New 
Mexico meadow jumping mouse is determinable. Our regulations at 50 CFR 
424.12(a)(2) state that critical habitat is not determinable when one 
or both of the following situations exist:
    (1) Information sufficient to perform required analyses of the 
impacts of the designation is lacking, or
    (2) The biological needs of the species are not sufficiently well 
known to permit identification of an area as critical habitat.
    When critical habitat is not determinable, the Act provides for an 
additional year to publish a critical habitat designation (16 U.S.C. 
1533(b)(6)(C)(ii)).
    We reviewed the available information pertaining to the biological 
needs of the species and habitat characteristics where this species is 
located. This and other information represent the best scientific data

[[Page 37331]]

available and led us to conclude that the designation of critical 
habitat is determinable for the New Mexico meadow jumping mouse.

Physical or Biological Features

    In accordance with section 3(5)(A)(i) and 4(b)(1)(A) of the Act and 
regulations at 50 CFR 424.12, in determining which areas within the 
geographical area occupied by the species at the time of listing to 
designate as critical habitat, we consider the physical or biological 
features that are essential to the conservation of the species and 
which may require special management considerations or protection. 
These include, but are not limited to:
    (1) Space for individual and population growth and for normal 
behavior;
    (2) Food, water, air, light, minerals, or other nutritional or 
physiological requirements;
    (3) Cover or shelter;
    (4) Sites for breeding, reproduction, or rearing (or development) 
of offspring; and
    (5) Habitats that are protected from disturbance or are 
representative of the historical, geographic, and ecological 
distributions of a species.
    We derive the specific physical or biological features required for 
the New Mexico meadow jumping mouse from studies of this species' 
habitat, ecology, and life history as described below. Unfortunately, 
there have been relatively few studies on the New Mexico meadow jumping 
mouse and its natural life history, and information gaps remain. 
However, we have used the best available information as described in 
the May 2013 SSA Report (Service 2013, entire). To identify the 
physical and biological needs of the New Mexico meadow jumping mouse, 
we have relied on conditions at currently occupied locations where the 
New Mexico meadow jumping mouse has been observed during surveys, and 
the best information available on the species and its close relatives. 
Below, we summarize the physical and biological features needed by 
foraging, breeding, and hibernating New Mexico meadow jumping mice. For 
a complete review of the physical and biological features required by 
the New Mexico meadow jumping mouse, see Chapter 2 in the May 2013 SSA 
Report (Service 2013, Chapter 2).
    For the New Mexico meadow jumping mouse to be considered viable, 
individual mice need specific vital resources for survival and 
completion of their life history. One of the most important aspects of 
the New Mexico meadow jumping mouse life history is that it hibernates 
about 8 or 9 months out of the year, longer than most mammals. 
Conversely, it is only active 3 or 4 months during the summer. Within 
this short time frame, it must breed, birth, and raise young, and store 
up sufficient fat reserves to survive the next year's hibernation 
period. In addition, New Mexico meadow jumping mice only live 3 years 
or less and have one small litter annually with 7 or fewer young, so 
the species has limited capacity for high population growth rates due 
to this low fecundity. As a result, if resources are not available in a 
single season, New Mexico meadow jumping mice populations would be 
greatly impacted.
    The New Mexico meadow jumping mouse has exceptionally specialized 
habitat requirements to support these life-history needs and maintain 
adequate population sizes. Habitat requirements are characterized by 
tall (averaging at least 61 cm (24 in)), dense herbaceous (plants with 
no woody tissue) riparian vegetation composed primarily of sedges and 
forbs. This suitable habitat is found only when wetland vegetation 
achieves full growth potential associated with perennial flowing water. 
This vegetation is an important resource need for the New Mexico meadow 
jumping mouse because it provides vital food sources (insects and 
seeds), as well as the structural material for building day nests that 
are used for shelter from predators. It is imperative that the New 
Mexico meadow jumping mouse have rich abundant food sources during the 
summer so it can accumulate sufficient fat reserves to survive their 
long hibernation period because the species does not cache food for the 
winter. In addition, individual New Mexico meadow jumping mice also 
need intact upland areas adjacent to riparian wetland areas because 
this is where they build nests or use burrows to give birth to young in 
the summer and to hibernate over the winter.
    These suitable habitat conditions need to be in appropriate 
locations and of adequate sizes to support healthy populations of the 
New Mexico meadow jumping mouse. Historically, these wetland habitats 
would have been in large patches located intermittently along long 
stretches of streams. The ability of New Mexico meadow jumping mouse 
populations to be resilient to adverse stochastic events depends on the 
robustness of a population and the ability to recolonize if populations 
are extirpated. Because counting individual New Mexico meadow jumping 
mice to assess population sizes is very difficult and data are 
unavailable, we can best measure population health by the size of the 
intact, suitable habitat available. We estimate that resilient 
populations of New Mexico meadow jumping mice need at least about 27.5 
to 73.2 ha (68 to 181 ac) of suitable habitat along 9 to 24 km (5.6 to 
15 mi) of flowing streams, ditches, or canals. This distribution and 
amount of suitable habitat would support multiple subpopulations of New 
Mexico meadow jumping mice throughout each of the waterways and would 
provide for sources of recolonization if some areas were extirpated due 
to disturbances, thereby increasing the chance of New Mexico meadow 
jumping mouse populations surviving the elimination or alteration of 
suitable habitat from a variety of sources and persisting while the 
necessary vegetation is restored. The suitable habitat patches must be 
relatively close together because the New Mexico meadow jumping mouse 
has limited dispersal capacity for natural recolonization. Range wide, 
we determined that the New Mexico meadow jumping mouse needs at least 
two resilient populations (where at least two existed historically) 
within each of eight identified geographic conservation areas. This 
number and distribution of resilient populations is expected to provide 
the species with the necessary redundancy and representation to provide 
for viability.
    Populations of New Mexico meadow jumping mice with a high 
likelihood of long-term viability require functionally connected areas 
throughout stream reaches, ditches, or canals. This continuous suitable 
habitat is necessary to attain the population sizes and densities 
needed to increase the probability that populations of the species will 
persist in the face of natural or manmade events and seasonal 
fluctuations of food resources. Because the species occurs only in 
areas that are water-saturated, populations have a high potential for 
extirpation when habitat dries due to ground and surface water 
depletion, draining of wetlands, or drought. New Mexico meadow jumping 
mouse habitat is subject to dynamic changes that result from flooding 
and drying of these waterways and the ensuing fluctuations (loss and 
regrowth) in the quantity and location of dense herbaceous riparian 
vegetation over time. Consequently, fluctuating water levels may create 
circumstances in which New Mexico meadow jumping mice population sizes 
and locations within a waterway vary over time, and populations may be 
periodically extirpated and subsequently recolonized. To encompass the 
daily

[[Page 37332]]

and seasonal movements of the majority of individual New Mexico meadow 
jumping mice and allow for the occasional inter-population dispersal to 
occur unimpeded, appropriately-sized patches of suitable habitat should 
be no more than about 100 m (330 feet) apart within these waterways.

Primary Constituent Elements

    Under the Act and its implementing regulations, we are required to 
identify the physical or biological features essential to the 
conservation of the New Mexico meadow jumping mouse in the geographic 
area occupied by the species at the time of listing, focusing on the 
features' primary constituent elements. We consider primary constituent 
elements to be the elements of physical or biological features that 
provide for a species' life-history processes and that are essential to 
the conservation of the species.
    Based on our current knowledge of the physical or biological 
features and habitat characteristics required to sustain the species' 
life-history processes (Service 2013, Chapter 2), we determine that the 
primary constituent elements (PCEs) specific to the New Mexico meadow 
jumping mouse consist of the following:
    (1) Riparian communities along rivers and streams, springs and 
wetlands, or canals and ditches characterized by one of two wetland 
vegetation community types:
    (a) Persistent emergent herbaceous wetlands dominated by beaked 
sedge (Carex rostrata) or reed canarygrass (Phalaris arundinacea) 
alliances; or
    (b) Scrub-shrub riparian areas that are dominated by willows (Salix 
spp.) or alders (Alnus spp.); and
    (2) Flowing water that provides saturated soils throughout the New 
Mexico meadow jumping mouse's active season that supports tall (average 
stubble height of herbaceous vegetation of at least 69 cm (27 inches) 
and dense herbaceous riparian vegetation (cover averaging at least 61 
vertical cm (24 inches) composed primarily of sedges (Carex spp. or 
Schoenoplectus pungens) and forbs, including, but not limited to one or 
more of the following associated species: Spikerush (Eleocharis 
macrostachya), beaked sedge (Carex rostrata), reed canarygrass 
(Phalaris arundinacea), rushes (Juncus spp. and Scirpus spp.), and 
numerous species of grasses such as bluegrass (Poa spp.), slender 
wheatgrass (Elymus trachycaulus), brome (Bromus spp.), foxtail barley 
(Hordeum jubatum), or Japanese brome (Bromus japonicas), and forbs such 
as water hemlock (Circuta douglasii), field mint (Mentha arvense), 
asters (Aster spp.), or cutleaf coneflower (Rudbeckia laciniata); and
    (3) Sufficient areas of 9 to 24 km (5.6 to 15 mi) along a stream, 
ditch, or canal that contain suitable or restorable habitat to support 
movements of individual New Mexico meadow jumping mice; and
    (4) Include adjacent floodplain and upland areas extending 
approximately 100 m (330 ft) outward from the water's edge (as defined 
by the bankfull stage of streams).
    This proposed designation is designed to support the necessary 
life-history functions of the species and the areas containing those 
PCEs in the appropriate quantity and spatial arrangement essential for 
the conservation of the species. We determined that these primary 
constituent elements of critical habitat provide for the physiological, 
behavioral, and ecological requirements of the species. New Mexico 
meadow jumping mice require herbaceous riparian vegetation associated 
with perennial (persistent) flowing water and adjacent uplands that can 
support the necessary habitat components needed by foraging, breeding, 
and hibernating individuals. New Mexico meadow jumping mice must also 
have sufficient cover within which to forage in an appropriate 
configuration and proximity to day, maternal, and hibernation nesting 
sites. This vegetation enables New Mexico meadow jumping mice to find 
adequate food resources not only to successfully raise young, but also 
to accumulate sufficient body fat for survival during hibernation. The 
appropriate configuration is provided by protecting multiple local 
populations throughout a minimum length of stream or ditch or canal of 
9 to 24 km (5.6 to 15 mi) of suitable habitat that will ensure 
sufficient resiliency of populations such that the species will be able 
to withstand and recover from periodic disturbances. Therefore, this 
amount of suitable habitat would support multiple local populations 
throughout each of the waterways, thereby increasing the chance of New 
Mexico meadow jumping mouse populations surviving the elimination or 
alteration of suitable habitat from a variety of sources and persisting 
while the necessary vegetation is restored.
    Populations of New Mexico meadow jumping mice with a high 
likelihood of long-term viability require functionally connected areas 
throughout stream reaches, ditches, or canals. This continuous suitable 
habitat is necessary to attain the population sizes and densities 
needed to increase the probability that populations of the species will 
persist in the face of natural or manmade events and seasonal 
fluctuations of food resources. This configuration of suitable habitat 
would encompass the daily and seasonal movements of the majority of 
individual New Mexico meadow jumping mice and would allow occasional 
inter-population dispersal to occur unimpeded.

Special Management Considerations or Protection

    When designating critical habitat, we assess whether the specific 
areas within the geographic area occupied by the species at the time of 
listing contain features that are essential to the conservation of the 
species and which may require special management considerations or 
protection. The features essential to the conservation of this species 
may require special management considerations or protection to reduce 
the following threats: Excessive grazing pressure, water use and 
management, highway reconstruction, development, severe wildland fires, 
unregulated recreation, the reduction in the distribution and abundance 
of beaver ponds. These threats have the potential to affect the PCEs if 
they are conducted within or adjacent to units proposed as critical 
habitat.
    Management activities that could ameliorate these threats include, 
but are not limited to: (1) Maintenance of occupied New Mexico meadow 
jumping mouse sites with active management to continue the protection 
of these areas from livestock grazing; (2) restoring, enhancing, and 
managing additional habitat through fencing of riparian areas, 
especially the Santa Fe, Lincoln, and Apache-Sitgreaves National 
Forests, to restore the required vegetative components and support the 
expansion of populations of the New Mexico meadow jumping mouse located 
since 2005 into areas that were historically occupied by the species, 
but where natural expansion is currently unlikely because no suitable 
habitat remains; (3) restoring habitat on Bosque del Apache National 
Wildlife Refuge (NWR) or other areas by carefully managing mowing and 
removing willows older than 5 years to maintain early seral habitat 
conditions along irrigation canals and ditches; and (4) developing and 
implementing a beaver management or restoration plan for occupied and 
historic New Mexico meadow jumping mouse localities where appropriate. 
A more complete discussion of the threats to the jumping mouse and its 
habitats can be found in the May 2013 SSA Report (Service 2013, Chapter 
5).

Criteria Used To Identify Critical Habitat

    The following discussion describes the process and methodology that 
we used to identify the areas to propose as critical habitat units for 
the New Mexico meadow jumping mouse. As required by section 4(b)(2) of 
the Act, we used the best scientific data available to designate 
critical habitat. We relied heavily on the analysis of biological 
information reviewed in the SSA Report (Service 2013, Chapters 2 and 
3). In accordance with section 3(5)(A) of the Act and its implementing 
regulation at 50 CFR 424.12(e), we determined the specific areas within 
the geographical area occupied by the species, at the time it is 
listed, where are found the physical or biological features that are 
essential to the conservation of the species and which may require 
special management considerations or protections (described earlier). 
Next, we determined the specific areas outside the geographical area 
occupied by the species at the time it is listed that are found to be 
essential for the conservation of the species. Finally, we described 
how we determined the lateral extent and mapping processes used in 
developing the proposed critical habitat units.
Occupied Areas--Section 3(5)(A)(i) of the Act
    Our initial step was to decide how to determine what areas are 
within the geographic area occupied by the New Mexico meadow jumping 
mouse at the time of listing (occupied areas). In reviewing all of the 
available data on New Mexico meadow jumping mouse occurrences, we 
decided that verified collections of the species between 2005 to 2012 
would be used to identify the areas considered occupied by the New 
Mexico meadow jumping mouse at the time of listing. This timeframe was 
selected because we found no capture records of New Mexico meadow 
jumping mice between 1996 and 2005. For a detailed review of this 
assessment, see Chapter 3 of the May 2013 SSA Report (Service 2013) 
where we referenced historical records as those from the 1980s and 
1990s and current records as those verified from 2005 to 2012. This 
assessment resulted in 29 locations of the New Mexico meadow jumping 
mouse considered occupied at the time of listing. However, there is 
uncertainty regarding the current status of the 29 populations that 
have been found since 2005 because 11 of the 29 populations have been 
substantially compromised since 2011 (due to water shortages, grazing, 
or wildfire and postfire flooding), and these populations could already 
be extirpated. Moreover, an additional seven populations may continue 
to experience loss of habitat from postfire flooding in the near term. 
Nevertheless, since no newer information has shown the New Mexico 
meadow jumping mouse to be extirpated from any of these locations, we 
find that the best available information supports considering these 
areas to be within the geographic area occupied by the New Mexico 
meadow jumping mouse at the time of listing.
    The occupied areas include the 29 locations that contain suitable 
habitat plus an additional 0.8-km (0.5-mi) segment upstream and 
downstream of these capture localities. These additional 0.8-km (0.5-
mi) segments are considered occupied because this is approximately the 
maximum dispersal distance that an individual New Mexico meadow jumping 
mouse has been observed to travel (744 meters, 2,441 feet; Frey and 
Wright 2012, pp. 16, 109). Although the species usually exhibits 
extreme site fidelity with regular daily and seasonal movements of less 
than 100 m (330 feet) (Frey and Wright 2012, pp. 16, 109), these 
additional 0.8-km (0.5-mi) segments have the potential to be occupied 
during the active season of the species if a New Mexico meadow jumping 
mouse moves the maximum known distance beyond the protective herbaceous 
cover found within the 29 locations. For each of the occupied areas, we 
next decided whether these areas contain the essential elements of 
physical and biological features which may require special management 
considerations or protections (PCEs and special management are 
described above). As noted, all of the 29 locations found since 2005 
are considered currently occupied by the New Mexico meadow jumping 
mouse and contain the essential PCEs (1 and 2), indicating each area 
requires special management considerations or protections to maintain 
those PCEs. Each of these 29 locations documented since 2005 occur 
within 1 of the 19 units or subunits (some units or subunits contain 
multiple occupied locations) proposed as critical habitat for the New 
Mexico meadow jumping mouse. For a site-by-site analysis of the 29 
locations, see the May 2013 SSA Report Chapter 4 (Service 2013).
Partially Occupied Areas--Section 3(5)(A)(ii) of the Act
    We then decided which areas that are outside the geographic area 
occupied by the species at the time of listing (unoccupied areas) are 
essential for the conservation of the New Mexico meadow jumping mouse. 
We first determined that, because of the loss of a substantial number 
(approximately 70) of historically occupied locations of the New Mexico 
meadow jumping mouse (Service 2013, Chapter 4) the number and 
distribution of populations should be increased at all of the currently 
occupied areas for the New Mexico meadow jumping mouse to be viable. 
The populations at these areas are needed to maintain sufficient 
redundancy and representation to provide for species viability (see 
Service 2013, Chapters 3 and 6). However, the areas occupied by the 
mouse since 2005 do not contain enough suitable, connected habitat to 
support resilient populations of New Mexico meadow jumping mouse 
(Service 2013, Chapter 3).
    Because the species needs multiple local populations along streams 
and other waterways to maintain genetic diversity and provide sources 
for recolonization when local populations are extirpated, it was 
important that we consider areas adjacent to the locations considered 
occupied by the mouse since 2005 to provide for population resiliency 
and species viability. We found that it is essential for the 
conservation of the New Mexico meadow jumping mouse to expand its 
occupied habitats into areas considered currently unoccupied, but 
within its historical range. The inclusion of essential but unoccupied 
areas will not only protect these segments and provide habitat for 
population expansion from the 29 locations documented since 2005, but 
also provide sites for possible future reintroduction that will improve 
the species' status through added population resiliency. For example, 
when unoccupied habitat is restored, the New Mexico meadow jumping 
mouse would have the ability to expand beyond the 0.8-km (0.5-mi) 
segments surrounding each of the 29 locations and populate the 
individual stream reaches or waterways. Consequently, the currently 
unoccupied segments within individual stream reaches or waterways need 
to be of sufficient size to allow for the expansion of current and 
future populations and provide connectivity (active season movements 
and dispersal) between multiple populations as they become established.
    So for each of the 19 areas (encompassing 29 locations) considered 
occupied, we proposed critical habitat units that include areas that 
are considered unoccupied adjacent to the occupied areas. The currently 
occupied areas contain the essential PCEs (1 and 2), indicating each 
area requires special management considerations or protections to 
maintain those PCEs;

[[Page 37334]]

however, the unoccupied areas are essential for the restoration of the 
essential PCEs (1, 2, 3, and 4) along streams and other waterways. Each 
of these units or subunits are considered ``partially occupied'' 
because they include some small areas that have been occupied by the 
species since 2005 and other larger areas upstream or downstream that 
are not known to be occupied by the New Mexico meadow jumping mouse at 
the time of listing.
    To decide what areas of unoccupied habitat should be included in 
proposed critical habitat units that are partially occupied, we focused 
on areas that had historical collection records confirmed to be the New 
Mexico meadow jumping mouse. Capture locations were then used to 
approximate previously occupied habitat and guide our proposed critical 
habitat areas. We then identified areas of potential habitat that have 
been recently restored, areas that likely still contain the habitat 
characteristics sufficient to support the life history of the species, 
or areas where functionally connected patches of suitable habitat will 
be required to provide for resilient populations and conserve the 
species.
    In considering how much area to include in proposed critical 
habitat units we considered how much suitable habitat might be needed 
to support resilient populations. In reviewing the available 
information, we think that New Mexico meadow jumping mouse populations 
generally need connected areas of suitable habitat along at least 9 to 
24 km (5.6 to 15 mi) of continuous suitable habitat to support viable 
populations of New Mexico meadow jumping mice with a high likelihood of 
long-term persistence (Service 2013, Section 2.7). This stream length 
is twice the length recommended by Frey (2011, p. 29) because we think 
it is important to account for the ability of populations to have a 
higher probability of withstanding catastrophic events such as 
wildfire. We used this length as a general guide for determining 
proposed critical habitat areas along waterways, but each unit and 
subunit were evaluated on a site-by-site basis to determine the best 
configuration of proposed critical habitat to support New Mexico meadow 
jumping mouse populations in that unit or subunit.
    In proposing critical habitat boundaries, we also considered the 
need for movement and dispersal to occur between suitable habitat areas 
within a proposed critical habitat unit or subunit. We do not 
anticipate that suitable habitat containing dense riparian herbaceous 
vegetation will be continuous throughout each of the critical habitat 
units or subunits, but rather, that suitable habitat should be disperse 
throughout waterways to allow for natural behaviors and perhaps 
occasional longer distance (i.e., from 200 to 700 m (656 to 2,297 ft)) 
exploratory movements (Frey and Wright 2012, p. 109), including 
dispersal.
    These movement and dispersal corridors are needed to connect sites 
that we consider occupied to one another within individual units or 
subunits, but not among units or subunits, which will enhance genetic 
exchange between New Mexico meadow jumping mouse populations and allow 
for natural recolonization if local populations are extirpated (Service 
2013, Section 2.6). Historically, populations were likely distributed 
throughout drainages, with a series of interconnected local populations 
(also called subpopulations) occupying suitable habitat patches within 
individual streams. Interconnected local populations were likely 
arranged within suitable habitat patches along streams in such a way 
that individuals could fulfill their daily and seasonal movements of 
about 100 m (330 feet), but also occasionally move greater distances 
(i.e., 200 to 744 m (656 to 2,441 ft)) to disperse to other habitat 
patches within stream segments (Frey and Wright 2012, p. 109). This 
ability to have multiple local populations is important to maintaining 
genetic diversity within the populations along streams and providing 
sources for recolonization when local populations are extirpated. For 
example, if a site is extirpated, recolonization from persisting local 
source populations within the same general area would have to occur 
along riparian corridors that contain suitable habitat (Frey 2011, p. 
41).
    As a result, the most likely routes for dispersal of New Mexico 
meadow jumping mice among sites would occur along perennial or 
intermittent drainages where habitat is present or restorable. Although 
we did not select specific areas in which to designate movement 
corridors, we assumed perennial drainages are better movement corridors 
than ephemeral or intermittent drainages, and the ephemeral or 
intermittent drainages are better movement corridors than upland 
routes. We also assume that, if all else is equal, the shorter the 
route the more likely New Mexico meadow jumping mice will successfully 
move. Because New Mexico meadow jumping mouse habitat is subject to the 
dynamic process of flooding, inundation, and drought, the extent and 
location of riparian corridors along streams and rivers may not remain 
constant and, depending on local conditions, are likely to expand and 
contract. Nevertheless, areas containing suitable habitat should be no 
more than about 100 m (330 feet) apart within these waterways, which 
would encompass the majority of daily and seasonal movements of 
individual New Mexico meadow jumping mice (Wright and Frey 2012, p. 
109). This configuration of habitat provides for a local population to 
be ``functionally connected,'' such that the movements of the majority 
of individual New Mexico meadow jumping mice and perhaps occasional 
interpopulation dispersal occur unimpeded.
    As a result of this analysis, we have determined that some of the 
areas within the proposed critical habitat units do not contain 
currently suitable habitat and are beyond the maximum known dispersal 
distance of 0.8 km (0.5 mi) to be considered occupied at any point in 
time. For example, within proposed Unit 2 we include the Harold Brock 
Fishing Easement that is located between the two sites that we consider 
occupied on Coyote Creek. The fishing easement is considered unoccupied 
because it does not currently contain suitable habitat and is beyond 
the daily and seasonal movement capacity of the species. Increasing the 
amount of suitable habitat in units like Coyote Creek is essential 
because it expands the available habitat within a given unit that can 
be occupied by the species and provides for potentially increasing 
population size within that riparian system. Increased population sizes 
are essential to conserving the species as higher numbers of 
individuals in the populations increases the likelihood of the 
persistence of the populations over time, in other words larger 
populations increase population resiliency.
Completely Unoccupied Areas--Section 3(5)(A)(ii) of the Act
    We next considered whether there were any other areas within the 
species' historical range but outside of the geographic area occupied 
at the time of listing (in other words completely unoccupied areas) 
that are essential for the conservation of the New Mexico meadow 
jumping mouse. In other words, we examined whether resilient 
populations at the 19 partially occupied proposed units (with 29 
locations occupied since 2005) would be sufficient to provide for 
viability of the New Mexico meadow jumping mouse. We reviewed the 
current and historical distribution of the species within each of the 
eight conservation areas across its range and the need for sufficient 
redundancy for the New Mexico

[[Page 37335]]

meadow jumping mouse (Service 2013, Chapter 3). With three exceptions, 
we found that each of the conservation areas would have sufficient 
populations to support species viability if the current New Mexico 
meadow jumping mouse areas were expanded to provide for resilient 
populations. The exceptions where the historic distribution is not 
adequately represented by recently located populations were in the 
Jemez Mountains, the Sacramento Mountains, and the Rio Grande 
conservation areas. We found that the conservation of the species 
requires increasing the number and distribution of populations of the 
New Mexico meadow jumping mouse to allow for the restoration and 
expansion of recently located populations into areas that were 
historically occupied within the Jemez Mountains, Sacramento Mountains, 
and the middle Rio Grande.
    We found four subunits (described under the Jemez Mountains, 
Sacramento Mountains, and middle Rio Grande Units below) within three 
conservation areas that are completely unoccupied, but are essential 
for the conservation of the New Mexico meadow jumping mouse. Inclusion 
of these areas provides for expansion of the overall geographic 
distribution of the species and increases the redundancy within these 
conservation areas. Much of the habitat within these four unoccupied 
subunits (Rio de las Vacas, Upper Rio Pe[ntilde]asco, Isleta Pueblo, 
and Ohkay Owingeh) contained New Mexico meadow jumping mice as recently 
as the late 1980s (Morrison 1985, entire; 1988, pp. 22-35; 1989, pp. 7-
23; 1992, p. 311; Frey 2005a, p. 7). For each of these unoccupied 
subunits, we found that, because of ongoing habitat loss, the 
conservation of the New Mexico meadow jumping mouse requires the 
protection of stream reaches with a high potential for restoration of 
suitable habitat to enable the reestablishment of the New Mexico meadow 
jumping mouse within areas that were historically occupied. The 
protection and restoration of suitable habitat within these areas will 
enable the reestablishment of the New Mexico meadow jumping mouse and 
increase its distribution to provide population redundancy and 
resiliency.
    In evaluating what areas are essential for the New Mexico meadow 
jumping mouse, we do not propose as critical habitat a number of 
historical locations of the New Mexico meadow jumping mouse because we 
do not think they are essential for conservation of the species. These 
omitted locations are, compared to other habitat segments, believed to 
be of lesser quality and do not contribute as much to connectivity, 
stability, or protection against catastrophic loss. Consequently, we 
are not proposing historical locations along riparian segments as 
critical habitat because we did not find them to be essential for 
conservation of the New Mexico meadow jumping mouse.
Lateral Extent
    To allow normal behavior and to ensure that the New Mexico meadow 
jumping mouse and the physical and biological features and sufficient 
PCEs on which it depends are protected, we believe that the outward 
extent of critical habitat from the riparian habitats should at least 
approximate the 100-year floodplain. Unfortunately, floodplains have 
not been mapped for many streams within the New Mexico meadow jumping 
mouse's range. While alternative delineation of critical habitat based 
on geomorphology and existing vegetation could accurately portray the 
presence and extent of required habitat components, we lack the 
explicit data to allow us to conduct such a delineation of critical 
habitat on a site-by-site basis. Moreover, some locations are 
associated with canals and ditches (e.g., Bosque del Apache NWR) that 
are manmade and do not have any associated floodplain. To address these 
issues, we propose to use a set distance of 100 m (328 ft) outward from 
either side of the river, stream, irrigation ditch, or canal's edge. 
The river, stream, irrigation ditch or canal's edge is defined by the 
bankfull stage. We believe this width is necessary to accommodate not 
only stream meandering and high flows within natural waterways, but 
also to capture essential upland areas in order to ensure that this 
proposed designation contains the features essential to all of the 
life-history stages (e.g., foraging, breeding, and hibernation) and the 
conservation of the species (Service 2013, Chapter 3). While this 
lateral extent of critical habitat may not extend outward to all areas 
used by individual mice over time, we expect that it will support the 
full range of PCEs essential for conservation of New Mexico meadow 
jumping mouse populations in these reaches.
    Bankfull stage is defined as the upper level of the range of 
channel-forming flows, which transport the bulk of available sediment 
over time. Bankfull stage is generally considered to be that level of 
stream discharge reached just before flows spill out onto the adjacent 
floodplain. The discharge that occurs at bankfull stage, in combination 
with the range of flows that occur over a length of time, govern the 
shape and size of the river channel (Rosgen 1996, pp. 2-2 to 2-4). The 
use of bankfull stage and 100 m (328 ft) on either side recognizes the 
naturally dynamic nature of riverine systems, recognizes that 
floodplains are an integral part of the stream ecosystem, and contains 
the area and associated features essential to the conservation of the 
species. Bankfull stage is not an ephemeral feature, meaning it does 
not disappear. Bankfull stage can always be determined and delineated 
for any stream and for the canals and ditches we are proposing as 
critical habitat. We acknowledge that the bankfull stage of any given 
segment may change depending on the magnitude of a flood event, but it 
is a definable and standard measurement for stream systems. Following 
high flow events, stream channels can move from one side of a canyon to 
the opposite side, for example. If we were to designate critical 
habitat based on the location of the stream on a specific date, the 
area within the designation could be a dry channel in less than 1 year 
from the publication of the determination, should a high flow event 
occur.
Mapping
    The critical habitat units that we propose were first delineated by 
creating rough areas for each unit by screen-digitizing polygons (map 
units) using Google Earth. We then digitized and refined the units 
using ArcMap version 10 (Environmental Systems Research Institute, 
Inc.), a computer Geographic Information System (GIS) program. The 
polygons were created by using current (2005 to 2012) and historical 
species (1985 to 1996) location points, which were then used in 
conjunction with hydrology, vegetation, and expert opinion. The 
location points were split into current and historical groups because 
we found no capture records of New Mexico meadow jumping mice between 
1996 and 2005.
    We set the limits of each critical habitat unit by identifying 
landmarks (islands, confluences, roadways, crossings, dams) that 
clearly delineated each area. Stream confluences are often used to 
delineate the boundaries of a unit for an aquatic species because the 
confluence of a tributary typically marks a significant change in the 
size or habitat characteristics of the stream. Stream confluences are 
also logical and recognizable termini. When a named tributary was not 
available, or if another landmark provided a more recognizable 
boundary, another landmark was used.
    When current or historical locations of New Mexico meadow jumping 
mice were used to delineate upstream and downstream boundaries of 
critical habitat, we extended the boundaries by

[[Page 37336]]

about 0.8 km (0.5 mi) to encompass areas that have the potential to be 
occupied during the active season of the species if a New Mexico meadow 
jumping mouse moves the maximum known distance beyond the protective 
herbaceous cover. However, we then refined the starting and end points 
by evaluating appropriate habitat conditions based on the presence or 
absence of perennial water or suitable vegetation. We selected upstream 
and downstream cutoff points that would avoid including highly degraded 
areas that are not likely restorable. For example, we did not include 
areas that were permanently dewatered or permanently developed (i.e., 
natural vegetation removed), or areas in which there was some other 
indication that suitable habitat no longer existed and was not likely 
to be restored.
    When determining proposed critical habitat boundaries, we also made 
every effort to avoid including developed areas such as lands covered 
by buildings, pavement, and other structures because such lands lack 
physical or biological features for the New Mexico meadow jumping 
mouse. The scale of the maps we prepared under the parameters for 
publication within the Code of Federal Regulations may not reflect the 
exclusion of such developed lands. Any such lands inadvertently left 
inside critical habitat boundaries shown on the maps of this proposed 
rule have been excluded by text in the proposed rule and are not 
proposed for designation as critical habitat. Therefore, if the 
critical habitat is finalized as proposed, a Federal action involving 
these lands would not trigger section 7 consultation with respect to 
critical habitat and the requirement of no adverse modification unless 
the specific action would affect the physical or biological features in 
the adjacent critical habitat.
Summary
    In summary, we are proposing for designation of critical habitat 
geographic areas that we have determined are occupied by the New Mexico 
meadow jumping mouse at the time of listing and contain sufficient 
elements of physical or biological features to support life-history 
processes essential for the conservation of the species and that 
require special management. Moreover, we are proposing to designate as 
critical habitat additional areas that are considered presently 
unoccupied, but essential to the conservation of the New Mexico meadow 
jumping mouse.
    The critical habitat designation is defined by the maps, as 
modified by any accompanying regulatory text, presented at the end of 
this document in the rule portion. We will make the coordinates or plot 
points or both on which each map is based available to the public on 
http://www.regulations.gov at Docket No. FWS-R2-ES-2013-0014, at http://www.fws.gov/southwest/es/NewMexico/, and at the New Mexico Ecological 
Services Field Office (see FOR FURTHER INFORMATION CONTACT above).

Proposed Critical Habitat Designation

    We are proposing to designate approximately 310.5 km (193.1 mi) 
(5,892 ha (14,560 ac)) in eight units as critical habitat for the New 
Mexico meadow jumping mouse in the states of Colorado, New Mexico, and 
Arizona. The critical habitat areas we describe below constitute our 
current best assessment of areas that meet the definition of critical 
habitat for the New Mexico meadow jumping mouse. The units we propose 
as critical habitat and the approximate area of each proposed critical 
habitat unit and land ownership are shown in Table 1. A summary of the 
proposed areas by land ownership and State are provided in Table 2.

Unit Descriptions

    We present brief descriptions of each of the proposed critical 
habitat units, and reasons why they meet the definition of critical 
habitat for the New Mexico meadow jumping mouse, below. For additional 
information on each unit, see the SSA (Service 2013, Chapter 4).
    We consider the 29 locations where the New Mexico meadow jumping 
mouse has been found since 2005 to be within the geographic area 
occupied at the time of listing (occupied areas). All of these occupied 
areas are contained within 19 of the 23 proposed critical habitats 
units that we refer to as partially occupied in Table 1. The exceptions 
are the completely unoccupied units (3-C Rio de las Vacas, 4-B Upper 
Rio Pe[ntilde]asco, 6-A Isleta Pueblo, and 6-B Ohkay Owingeh 3-C). We 
specifically describe each of the occupied areas within the proposed 
critical habitat unit descriptions presented below. All of these 
occupied areas contain suitable habitat with one or more of the 
essential physical or biological features that require special 
management and are, therefore, included in the proposed designation 
under section 3(5)(A)(i) of the Act. All of these occupied areas 
exhibit: PCE 1--appropriate wetland vegetation communities and PCE 2--
flowing water with tall herbaceous vegetation. The occupied areas 
within these 19 proposed units may require special management or 
protection to address the direct or indirect loss or alteration of the 
essential physical and biological features. These special management 
considerations or protections are needed

[[Page 37339]]

to address: Water development, recreational use, livestock grazing, 
road reconstruction, the loss of beaver ponds, and vegetation mowing.
    Every proposed critical habitat unit contains areas outside the 
geographic area occupied by the species at the time of listing 
(unoccupied areas) that we conclude are essential for the conservation 
of the New Mexico meadow jumping mouse. As noted, four of these units 
(3-C Rio de las Vacas, 4-B Upper Rio Pe[ntilde]asco, 6-A Isleta Pueblo, 
and 6-B Ohkay Owingeh 3-C) are considered completely unoccupied. The 
remaining 19 proposed critical habitat units include unoccupied areas 
that are up- or downstream of the occupied areas, but do not currently 
have the necessary vegetation to protect New Mexico meadow mice from 
predators or to provide food sources. We describe these units 
containing both occupied and unoccupied areas within the same stream 
reach as partially occupied (Table 1). All of these completely or 
partially unoccupied areas currently have flowing water to allow for 
future restoration of the essential PCEs 1 and 2, but also PCE 3--
sufficient areas of streams, ditches or canals; and PCE 4--adjacent 
floodplain and upland areas that would collectively provide the needed 
physical and biological features of habitat required to sustain the 
species' life-history processes.
    We conclude that all of these areas, whether they are within 
partially or completely unoccupied proposed units, are essential to the 
conservation of the New Mexico meadow jumping mouse because: (1) The 
areas occupied by the mouse since 2005 do not contain enough suitable, 
connected habitat to support resilient populations of New Mexico meadow 
jumping mouse; (2) the currently unoccupied segments within individual 
stream reaches or waterways need to be of sufficient size to allow for 
the expansion of populations and provide connectivity (active season 
movements and dispersal) between multiple populations as they become 
established; (3) additional areas need habitat protection to allow 
restoration of the necessary herbaceous vegetation for possible future 
reintroductions; and (4) multiple local populations along streams are 
important to maintaining genetic diversity within the populations and 
for providing sources for recolonization if local populations are 
extirpated. Therefore, all of the unoccupied areas are included in the 
proposed designation under section 3(5)(A)(ii) of the Act.

Unit 1: Sugarite Canyon

    Unit 1 consists of 687 ha (1,698 ac) along 13.0 km (8.1 mi) of 
streams on private lands and areas owned by the States of Colorado and 
New Mexico. The Colorado streams areas are found within Las Animas 
County, Colorado, and the New Mexico stream areas are found within 
Colfax County, New Mexico. The unit begins 0.6 km (0.4 mi) north of the 
headwaters of Lake Dorothey, Colorado, along the East Fork and 1.1 km 
(0.7 mi) north of the headwaters of Lake Dorothey along the West Fork 
of Schwacheim Creek and follows the drainage downstream, to include a 
2.0 km (1.25 mi) segment of Chicorica Creek that is a tributary flowing 
into the headwaters of Lake Maloya and a 0.8 km (0.5 mi) segment of 
Segerstrom Creek which is a tributary flowing into the western edge of 
Lake Maloya, New Mexico. The unit continues through Lake Maloya and 
includes about 1.8 km (1.1 mi) of the small western tributary Soda 
Pocket Creek, which flows into and includes lower Chicorica Creek below 
Lake Maloya Dam downstream to the terminus of the area at Lake Alice 
Dam within Sugarite Canyon State Park.
    Based upon captures of the New Mexico meadow jumping mouse since 
2005 (Frey 2006d, pp. 19-21, 67) approximately 2.8 ha (7 ac) within 
this unit in Sugarite Canyon State Park in New Mexico are considered 
occupied at the time of listing and contain suitable habitat. The 
occupied areas occur along the Canyon at five locations: Chicorica 
Creek 0.6 km (0.4 mi) below Lake Maloya Dam; Segerstrom Creek just 
above the western confluence with Lake Maloya; the headwaters of Lake 
Alice; and Soda Pocket Creek and Campground along the two streams that 
cross the open meadow on Barlett Mesa near the campfire program area 
and behind campsite number 16 (Frey 2006d, pp. 19-21, 67). In 2011, the 
Track Fire burned nearly the entire watershed of Sugarite Canyon, and 
surveys have not been conducted to determine whether New Mexico meadow 
jumping mice still persist postfire (Service 2012c). However, until new 
information is collected we consider this area within the geographical 
area occupied by the New Mexico meadow jumping mouse at the time of 
listing. The features essential to the conservation of this species may 
require special management considerations or protection to reduce the 
following threats: Severe wildland fires, recreation, grazing, water 
use and management, floods, the reduction in the distribution and 
abundance of beaver ponds, and coalbed methane. The occupied areas are 
centered around the five capture locations plus an additional 0.8-km 
(0.5-mi) segment upstream and downstream of these areas where the 
physical and biological features are found. The remaining unoccupied 
areas within Unit 1 are found both upstream and downstream of the 
occupied areas, and are considered essential to the conservation of the 
New Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).

Unit 2: Coyote Creek

    Unit 2 consists of 239 ha (590 ac) along 11.8 km (7.4 mi) of Coyote 
Creek on private lands and an area owned by the State of New Mexico 
within Mora County. The unit begins at the confluence of Little Blue 
Creek and Coyote Creek and extends downstream about to the terminus 
just south of the Village of Guadalupita.
    Based upon captures of the New Mexico meadow jumping mouse since 
2006 (Frey 2006d, pp. 24, 70; Frey 2012, p. 6), approximately 1.7 ha 
(4.3 ac) within this unit in Coyote Creek State Park and several miles 
north of the park along Highway 434 in New Mexico are considered 
occupied at the time of listing and contain suitable habitat. The 
occupied areas occur at two locations along Coyote Creek including: an 
area that contains extensive beaver ponds, dams, and canals and is 
located between the only vehicle bridge within the southwestern part of 
Coyote Creek State Park and the southern boundary of the park; and 
within another area that contains extensive beaver activity about 1.9 
km (1.2 mi) south of the confluence of Little Blue Creek and Coyote 
Creek. The features essential to the conservation of this species may 
require special management considerations or protection to reduce the 
following threats: severe wildland fires, recreation, grazing, water 
use and management, floods, the reduction in the distribution and 
abundance of beaver ponds, and development. The occupied areas are 
centered around the two capture locations plus an additional 0.8-km 
(0.5-mi) segment upstream and downstream of these areas where the 
physical and biological features are found. The remaining unoccupied 
areas within Unit 2 are found both upstream and downstream of the 
occupied areas, and are considered essential to the conservation of the 
New Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).

Unit 3: Jemez Mountains

    Unit 3 consists of 1,118 ha (2,761 ac) of streams within three 
subunits on private lands and areas owned by the Forest Service and the 
State of New Mexico within Sandoval County, New Mexico. Areas proposed 
for critical habitat for the New Mexico meadow jumping mouse in this 
unit incorporate the only habitat known to be occupied by the species 
since 2005 within the Jemez Mountains with the capability to support 
the breeding and reproduction of the species.
Subunit 3-A; San Antonio Creek
    Subunit 3-A consists of 234 ha (579 ac) along 11.5 km (7.1 mi) of 
San Antonio Creek on private lands and areas owned by the Forest 
Service. This subunit begins along the northern part of San Antonio 
Creek where it exits the boundary of the Valles Caldera National 
Preserve and follows the creek through mostly Forest Service lands 
where it meets private land immediately downstream of the San Antonio 
Campground.
    Based upon the capture of one New Mexico meadow jumping mouse since 
2005 (Frey 2005a, pp. 15, 24, 58), approximately 0.4 ha (1 ac) within 
this unit along San Antonio Creek are considered occupied at the time 
of listing and contain suitable habitat. The occupied area is located 
within a wet meadow near the southwestern part of San Antonio 
Campground (Frey 2005a, pp. 15, 24, 58). The features essential to the 
conservation of this species may require special management 
considerations or protection to reduce the following threats: severe 
wildland fires, recreation, grazing, floods, and the reduction in the 
distribution and abundance of beaver ponds. The occupied area is 
centered around the capture location plus an additional 0.8-km (0.5-mi) 
segment upstream and downstream of this area where the physical and 
biological features are found. The remaining unoccupied areas within 
Subunit 3-A are found both upstream and downstream of the occupied 
area, and are considered essential to the conservation of the New 
Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).
Subunit 3-B; Rio Cebolla
    Subunit 3-B consists of 429 ha (1,060 ac) along 20.7 km (12.9 mi) 
of the Rio Cebolla on private lands and areas owned by the Forest 
Service and the State of New Mexico. This subunit extends from an old 
beaver dam about 0.6 km (0.4 mi) north of Hay Canyon downstream about 
where it meets the Rio de las Vacas.
    Based upon captures of the New Mexico meadow jumping mouse since 
2005 (Frey 2005a, pp. 23-28, 37-38; Frey 2007b, p. 11), approximately 
10.7 ha (26.4 ac) within this unit on State of New Mexico and Forest 
Service lands in New Mexico are considered occupied at the time of 
listing and contain suitable habitat. The occupied areas occurs at six 
locations along the Rio Cebolla: near the western edge of the 
northwestern pond along the access road within the New Mexico 
Department of Game and Fish's Seven Springs Hatchery; within Fenton 
Lake State Park at the upper end of Fenton Lake Marsh above Highway 126 
and the New Mexico Highway 126 bridge; within Fenton Lake State Park 
Day Use Area at the mouth of a small tributary that enters the 
southwest side of Fenton Lake; within Lake Fork Canyon inside a 
livestock exclosure above the bridge on Forest Road 376; within a 
network of channels, beaver ponds, and wet meadows about 0.9 kilometers 
(0.6 miles) southwest of Forest Road 376 bridge; and about 2.7 km (1.7 
mi) north of the confluence of the Rio Cebolla and the Rio de las Vacas 
(Frey 2005a, pp. 23-28, 37-38; Frey 2007b, p. 11). The features 
essential to the conservation of this species may require special 
management considerations or protection to reduce the following 
threats: severe wildland fires, recreation, grazing, floods, the 
reduction in the distribution and abundance of beaver ponds, 
development, and highway reconstruction. The occupied areas are 
centered around the six capture locations plus an additional 0.8-km 
(0.5-mi) segment upstream and downstream of these areas where the 
physical and biological features are found. The remaining unoccupied 
areas within Subunit 3-B are found both upstream and downstream of the 
occupied areas, and are considered essential to the conservation of the 
New Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).
Subunit 3-C; Rio de las Vacas
    Subunit 3-C consists of 454 ha (1,122 ac) along 23.3 km (14.5 mi) 
of the Rio de las Vacas on private lands and areas owned by the Forest 
Service. This subunit starts about 0.8 km (0.5 mi) north of Forest Road 
94 adjacent to Burned Canyon and extends downstream to the confluence 
with the Rio Cebolla Subunit.
    Although much of the habitat was historically occupied with 
individuals detected as recently as 1989 (Morrison 1985; 1992, p. 311; 
Frey 2005a, p. 7), no New Mexico meadow jumping mice were captured 
during surveys in 2005 (Frey 2005a, p. 18). The entire subunit is 
considered unoccupied at the time of listing. All of the areas within 
the Subunit 3-C are considered essential to the conservation of the New 
Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).

Unit 4: Sacramento Mountains

    Unit 4 consists of 777 ha (1,920 ac) of streams within five 
subunits on private lands and areas owned by the Forest Service within 
Otero County, New Mexico. Areas proposed for critical habitat for the 
New Mexico meadow jumping mouse in this unit incorporate the only 
habitat known to be occupied by the species since 2005 within the 
Sacramento Mountains with the capability to support the breeding and 
reproduction of the species.
Subunit 4-A; Silver Springs
    Subunit 4-A consists of 105 ha (260 ac) along 5.2 km (3.2 mi) of 
Silver Springs Creek on private lands and areas owned by the Forest 
Service. This subunit begins about 0.3 km (0.2 mi) north of the 
intersection of Forest Road 162 and New Mexico Highway 244 and follows 
Silver Springs Creek downstream to the boundary of Forest Service and 
Mescalero Apache lands.
    Based upon the capture of one New Mexico meadow jumping mouse since 
2005 (Frey 2005a, p. 31), approximately 5.4 ha (13.3 ac) within this 
unit on Forest Service lands in New Mexico are considered occupied at 
the time of listing. The occupied area is located within a grazing 
exclosure containing well-developed riparian habitat about 7.4 km (4.6 
mi) north of Cloudcroft along middle Silver Springs Creek, at Junction 
of Turkey Pen Canyon and Forest Road 405 (Frey 2005a, pp. 31, 38). The 
features essential to the conservation of this species may require 
special management considerations or protection to reduce the following 
threats: severe wildland fires, grazing, floods, and the reduction in 
the distribution and abundance of beaver ponds. The occupied area is 
centered around the capture location plus an additional 0.8-km (0.5-mi) 
segment upstream and downstream of this area where the physical and 
biological features are found. The remaining unoccupied areas within 
Subunit 4-A are found both upstream and downstream of the occupied 
area, and are considered essential to the conservation of the New 
Mexico meadow jumping mouse (as described

in the Unit Description introduction section above).
Subunit 4-B; Upper Rio Pe[ntilde]asco
    Subunit 4-B consists of 136 ha (335 ac) along 6.4 km (4.0 mi) of 
the Rio Pe[ntilde]asco on private lands and areas owned by the Forest 
Service. This subunit begins at the junction of Forest Service Road 164 
and New Mexico Highway 6563 and follows the Rio Pe[ntilde]asco drainage 
downstream to about 2.4 km (1.5 mi) below Bluff Spring at the boundary 
of private and Forest Service lands.
    Although much of the habitat was historically occupied with 
individuals detected as recently as 1988 (Morrison 1989, pp. 7-10, Frey 
2005a, pp. 30-31), no New Mexico meadow jumping mice were captured 
during surveys in 2005 (Frey 2005a, pp. 19-20, 32-34). The entire 
subunit is considered unoccupied at the time of listing. All of the 
areas within the Subunit 4-B are considered essential to the 
conservation of the New Mexico meadow jumping mouse (as described in 
the Unit Description introduction section above).
Subunit 4-C; Middle Rio Pe[ntilde]asco
    Subunit 4-C consists of 264 ha (652 ac) along 11.4 km (7.1 mi) of 
the Rio Pe[ntilde]asco on private lands and areas owned by the Forest 
Service. This subunit begins at the junction of Wills Canyon and Forest 
Service Road 169 and follows the Rio Pe[ntilde]asco drainage downstream 
to the junction of Forest Road 212.
    Based upon the capture of two New Mexico meadow jumping mice in 
2012, following the cessation of grazing for 2 years, (Forest Service 
2012h, pp. 2-4; Service 2012d; U.S. Army Corps of Engineers 2012, 
entire; 2012a, entire), approximately 0.3 ha (0.75 ac) within this unit 
on Forest Service lands in New Mexico are considered occupied at the 
time of listing. The occupied area is located within a wetland at the 
junction of Cox Canyon and the Rio Pe[ntilde]asco (Forest Service 
2012h, pp. 2-4). The features essential to the conservation of this 
species may require special management considerations or protection to 
reduce the following threats: severe wildland fires, recreation, 
grazing, floods, and the reduction in the distribution and abundance of 
beaver ponds. The occupied area is centered around the capture location 
plus an additional 0.8-km (0.5-mi) segment upstream and downstream of 
this area where the physical and biological features are found. The 
remaining unoccupied areas within Subunit 4-C are found both upstream 
and downstream of the occupied area, and are considered essential to 
the conservation of the New Mexico meadow jumping mouse (as described 
in the Unit Description introduction section above).
Subunit 4-D; Wills Canyon
    Subunit 4-D consists of 111 ha (275 ac) along 5.6 km (3.5 mi) of 
streams on private lands and areas owned by the Forest Service. This 
subunit begins at upper Mauldin Spring, the head of the Wills Canyon, 
and follows the drainage downstream along Forest Service Road 169 to 
the boundary of Forest Service and private lands in the vicinity of 
Bear Spring.
    Based upon the capture of one New Mexico meadow jumping mouse in 
2012 (Forest Service 2012b, entire; 2012c, entire; 2012h, pp. 2-5), 
approximately 0.8 ha (1.9 ac) within this unit on Forest Service lands 
in New Mexico are considered occupied at the time of listing. The 
occupied area is located within a grazing exclosure at Lower Mauldin 
Spring in Wills Canyon (Forest Service 2012h, pp. 2-5). The features 
essential to the conservation of this species may require special 
management considerations or protection to reduce the following 
threats: severe wildland fires, grazing, floods, and the reduction in 
the distribution and abundance of beaver ponds. The occupied area is 
centered around the capture location plus an additional 0.8-km (0.5-mi) 
segment upstream and downstream of this area where the physical and 
biological features are found. The remaining unoccupied areas within 
Subunit 4-D are found both upstream and downstream of the occupied 
area, and are considered essential to the conservation of the New 
Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).
Subunit 4-E; Agua Chiquita Canyon
    Subunit 4-E consists of 161 ha (398 ac) along 7.7 km (4.8 mi) of 
Agua Chiquita Creek on areas owned by the Forest Service. This subunit 
begins about 0.8 km (0.5 mi) upstream of the livestock exclosure around 
Barrel and Sand Springs along Agua Chiquita Creek and follows the 
canyon downstream along Forest Service Road 64 to Crisp, a Forest 
Service riparian pasture.
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2005 (Frey 2005a, p. 34; Forest Service 2010, entire; Service 
2012d, pp. 1-2), approximately 4.9 ha (12.0 ac) within this unit on 
Forest Service lands in New Mexico are considered occupied at the time 
of listing. The occupied areas are located within two of four fenced 
livestock exclosures including: the exclosure surrounding Sand and 
Barrel Springs and the most downstream section of the second in the 
series of four exclosures (Frey 2005a, p. 34; Forest Service 2010, 
entire; Service 2012d, pp. 1-2). The features essential to the 
conservation of this species may require special management 
considerations or protection to reduce the following threats: severe 
wildland fires, recreation, grazing, floods, and the reduction in the 
distribution and abundance of beaver ponds. The occupied areas are 
centered around the two capture locations plus an additional 0.8-km 
(0.5-mi) segment upstream and downstream of these areas where the 
physical and biological features are found. The remaining unoccupied 
areas within Subunit 4-E are found both upstream and downstream of the 
occupied areas, and are considered essential to the conservation of the 
New Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).

Unit 5: White Mountains

    Unit 5 consists of 2,448 ha (6,047 ac) of streams within eight 
subunits on private lands and areas owned by the Forest Service and the 
State of Arizona within Greenlee and Apache Counties, Arizona. Areas 
proposed for critical habitat for the New Mexico meadow jumping mouse 
in this unit incorporate the only habitat known to be occupied by the 
species since 2005 within the White Mountains with the capability to 
support the breeding and reproduction of the species.
Subunit 5-A; Little Colorado River
    Subunit 5-A consists of 478 ha (1,181 ac) along 22.6 km (14.0 mi) 
of the Little Colorado River on private lands and areas owned by the 
Forest Service. This subunit encompasses the East and West Forks of the 
Little Colorado River. The East Fork Segment begins 0.8 km (0.5 mi) 
upstream of the Phelps Research Natural Area and follows the drainage 
downstream about 3.2 km (2.0 mi) to the confluence of Lee Valley Creek 
and then runs upstream about 1.6 km (1.0 mi) to the dam of Lee Valley 
Reservoir. The subunit continues from the confluence of Lee Valley 
Creek and the East Fork, downstream to the confluence of the West Fork 
of the Little Colorado River, continuing to about 8.9 km (5.5 mi) 
upstream along the drainage to about 0.8 km (0.5 mi) past Sheep's 
Crossing.
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2008 (Frey 2011, p. 87; ADGF 2012a, p. 3), approximately 0.6 ha 
(1.5 ac) within

[[Page 37342]]

this unit on Forest Service lands in Arizona are considered occupied at 
the time of listing. The occupied area is within a livestock exclosure 
along a short 0.4-km stream reach that is 1.8 km (1.1 mi) south of 
Greer, below Montlure Camp ((Frey 2011, p. 87; ADGF 2012a, p. 3). In 
2011, the Wallow Fire burned much of this area, and surveys during 2012 
continued to detect New Mexico meadow jumping mice (ADGF 2012a, p. 3). 
The features essential to the conservation of this species may require 
special management considerations or protection to reduce the following 
threats: severe wildland fires, recreation, grazing, floods, the 
reduction in the distribution and abundance of beaver ponds, and 
development. The occupied areas are centered around the capture 
locations plus an additional 0.8-km (0.5-mi) segment upstream and 
downstream of this area where the physical and biological features are 
found. The remaining unoccupied areas within Subunit 5-A are found both 
upstream and downstream of the occupied area, and are considered 
essential to the conservation of the New Mexico meadow jumping mouse 
(as described in the Unit Description introduction section above).
Subunit 5-B; Nutrioso Creek
    Subunit 5-B consists of 413 ha (1,021 ac) along 20.4 km (12.7 mi) 
of Nutrioso Creek on private lands and areas owned by the Forest 
Service. This subunit begins at the confluence of Paddy Creek about 4.8 
km (3 mi) south of the town of Nutrioso and follows the drainage 
downstream about 16 km (10 mi) to Nelson Reservoir.
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2008 (Frey 2011, pp. 29, 35, 89, 95; ADGF 2012a, p. 3), 
approximately 1.9 ha (4.9 ac) within this unit on Forest Service lands 
in Arizona are considered occupied at the time of listing. The occupied 
area is a short 1.3-km (0.8-mi) stream reach 3.9 km (2.4 mi) south of 
the town of Nutrioso. In 2011, the Wallow Fire burned much of this 
area, and surveys during 2012 continued to detect New Mexico meadow 
jumping mice (ADGF 2012a, p. 3). The features essential to the 
conservation of this species may require special management 
considerations or protection to reduce the following threats: severe 
wildland fires, grazing, floods, the reduction in the distribution and 
abundance of beaver ponds, highway reconstruction, and development. The 
occupied area is centered around the capture locations plus an 
additional 0.8-km (0.5-mi) segment upstream and downstream of this area 
where the physical and biological features are found. The remaining 
unoccupied areas within Subunit 5-B are found both upstream and 
downstream of the occupied area, and are considered essential to the 
conservation of the New Mexico meadow jumping mouse (as described in 
the Unit Description introduction section above).
Subunit 5-C; San Francisco River
    Subunit 5-C consists of 252 ha (622 ac) along 11.8 km (7.3 mi) of 
the San Francisco River and its tributary Turkey (=Talwiwi) Creek on 
private lands and areas owned by the Forest Service. This subunit 
begins about 0.6 km (0.4 mi) west of Forest Road 8854 along the San 
Francisco River and follows the drainage downstream about 10.5 km (6.5 
mi), including a 1.3-km (0.8-mi) segment of Turkey (= Talwiwi) Creek 
that is south of Arizona Highway 180, then continues downstream to the 
headwaters of Luna Lake.
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2008 (Frey 2011, p. 97), approximately 0.9 ha (2.3 ac) within 
this unit on Forest Service lands in Arizona are considered occupied at 
the time of listing. There are two occupied areas within this unit 
including: a small livestock exclosure along a 0.2-km (0.1-mi) stream 
reach of upper Turkey Creek at the junction of Highway 80 and Forest 
Road 289; and two fenced livestock exclosures along a 0.4-km (0.2-mi) 
stream reach at the junction of the San Francisco River and Forest Road 
8854 (Frey 2011, p. 97). In 2011, the Wallow Fire burned much of this 
area, and surveys during 2012 did not detect New Mexico meadow jumping 
mice (ADGF 2012, entire, 2012a, p. 2). However, until multiple years of 
surveys determine that the population has been extirpated, we consider 
this area within the geographical area occupied by the New Mexico 
meadow jumping mouse at the time of listing. The features essential to 
the conservation of this species may require special management 
considerations or protection to reduce the following threats: severe 
wildland fires, grazing, floods, the reduction in the distribution and 
abundance of beaver ponds, highway reconstruction, and development. The 
occupied areas are centered around the capture locations plus an 
additional 0.8-km (0.5-mi) segment upstream and downstream of these 
areas where the physical and biological features are found. The 
remaining unoccupied areas within Subunit 5-C are found both upstream 
and downstream of the occupied areas, and are considered essential to 
the conservation of the New Mexico meadow jumping mouse (as described 
in the Unit Description introduction section above).
Subunit 5-D; East Fork Black River
    Subunit 5-D consists of 421 ha (1,040 ac) along 20.3 km (12.6 mi) 
of the East Fork of the Black River areas owned by the Forest Service. 
This subunit begins 0.8 km (0.5 mi) north of the intersection of Three 
Forks Road and Route 285 and follows the drainage downstream about 20.3 
km (12.6 mi), where it abuts the West Fork Black River Subunit (see 
``West Fork Black River Subunit'' below).
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2008 (Frey 2011, p. 97; ADGF 2012, entire, 2012a, p. 2), 
approximately 6.9 ha (16.9 ac) within this unit on Forest Service lands 
in Arizona are considered occupied at the time of listing. The occupied 
area is located along the headwaters of the East Fork Black River near 
the intersection of Three Forks Road and Route 285 (Frey 2011, p. 97; 
ADGF 2012, entire, 2012a, p. 2). In 2011, the Wallow Fire burned much 
of this area and surveys during 2012 continued to detect New Mexico 
meadow jumping mice (ADGF 2012a, p. 2). The features essential to the 
conservation of this species may require special management 
considerations or protection to reduce the following threats: severe 
wildland fires, grazing, floods, the reduction in the distribution and 
abundance of beaver ponds, and highway reconstruction. The occupied 
area is centered around the capture location plus an additional 0.8-km 
(0.5-mi) segment upstream and downstream of this area where the 
physical and biological features are found. The remaining unoccupied 
areas within Subunit 5-D are found both upstream and downstream of the 
occupied area, and are considered essential to the conservation of the 
New Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).
Subunit 5-E; West Fork Black River
    Subunit 5-E consists of 481 ha (1,188 ac) along 23.0 km (14.3 mi) 
of the West Fork of the Black River on private lands and areas owned by 
the Forest Service and the State of Arizona. The proposed subunit 
begins at the confluence of the West Fork of the Black River and Burro 
Creek and follows the drainage downstream where it abuts the East Fork 
Black River Subunit (see ``East Fork Black River Subunit'' above).
    Based upon multiple captures of New Mexico meadow jumping mice 
since

[[Page 37343]]

2008 (Frey 2011, p. 97; ADGF 2012, entire, 2012a, p. 2), approximately 
13.7 ha (33.9 ac) within this unit on Forest Service lands in Arizona 
are considered occupied at the time of listing. The occupied areas 
occur at four locations: along the upper West Fork Black River just 
north of Forest Road 116; immediately adjacent to the campground along 
the middle Fork of the Black River; at the junction of Forest Road 68 
and the middle Fork of the Black River; and near the junction of the 
lower Fork of the Black River and Home Creek (Frey 2011, p. 97; ADGF 
2012, entire, 2012a, pp. 2-3). In 2011, the Wallow Fire burned much of 
this area and surveys during 2012 continued to detect New Mexico meadow 
jumping mice at the lower and middle sections of the West Fork Black 
River (ADGF 2012a, pp. 2-3). Although New Mexico meadow jumping mice 
were not detected at the upper West Fork Black River location, until 
multiple years of surveys determine that the population has been 
extirpated, we consider this area within the geographical area occupied 
by the New Mexico meadow jumping mouse at the time of listing. The 
features essential to the conservation of this species may require 
special management considerations or protection to reduce the following 
threats: severe wildland fires, grazing, floods, the reduction in the 
distribution and abundance of beaver ponds, and highway reconstruction. 
The occupied areas are centered around the capture locations plus an 
additional 0.8-km (0.5-mi) segment upstream and downstream of these 
areas where the physical and biological features are found. The 
remaining unoccupied areas within Subunit 5-E are found both upstream 
and downstream of the occupied areas, and are considered essential to 
the conservation of the New Mexico meadow jumping mouse (as described 
in the Unit Description introduction section above).
Subunit 5-F; Boggy Creek and Centerfire Creeks
    Subunit 5-F consists of 196 ha (485 ac) along 8.9 km (5.5 mi) of 
Boggy Creek and Centerfire Creek on areas owned by the Forest Service. 
The East Segment of the subunit begins 0.8 km (0.5 mi) north of the 
intersection of Route 25 and Boggy Creek and follows the drainage 
downstream to the confluence with Centerfire Creek. The West segment 
begins 0.8 km (0.5 mi) north of the intersection of Route 25 and 
Centerfire Creek and follows the drainage downstream to the confluence 
with Boggy Creek, then continues downstream to the confluence with the 
Black River.
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2008 (Frey 2011, pp. 104-105; ADGF 2012, entire, 2012, p. 3), 
approximately 3.0 ha (7.5 ac) within this unit on Forest Service lands 
in Arizona are considered occupied at the time of listing. The occupied 
areas are located within fenced livestock exclosures at the junction of 
Forest Road 25 and Boggy Creek; and within a fenced livestock exclosure 
at the junction of Forest Road 25 and Centerfire Creek (Frey 2011, pp. 
104-105; ADGF 2012, entire, 2012, p. 3). In 2011, the Wallow Fire 
burned much of this area, and surveys during 2012 continued to detect 
New Mexico meadow jumping mice (ADGF 2012a, p. 3). The features 
essential to the conservation of this species may require special 
management considerations or protection to reduce the following 
threats: severe wildland fires, grazing, floods, and the reduction in 
the distribution and abundance of beaver ponds. The occupied areas are 
centered around the capture locations plus an additional 0.8-km (0.5-
mi) segment upstream and downstream of these areas where the physical 
and biological features are found. The remaining unoccupied areas 
within Subunit 5-F are found both upstream and downstream of the 
occupied areas, and are considered essential to the conservation of the 
New Mexico meadow jumping mouse (as described in the Unit Description 
introduction section above).
Subunit 5-G; Corduroy Creek
    Subunit 5-G consists of 104 ha (256 ac) along 4.8 km (3.0 mi) of 
Corduroy Creek on lands owned by the Forest Service. The proposed 
subunit begins at the headwaters about 0.8 km (0.5 mi) south of the 
intersection of County Road 24 and County Road 8184A and follows the 
drainage downstream to the confluence with Fish Creek.
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2009 (Frey 2011, pp. 104-105; ADGF 2012, entire, 2012a, p. 4), 
approximately 0.4 ha (1.1 ac) within this unit on Forest Service lands 
in Arizona are considered occupied at the time of listing. The occupied 
area is located within fenced livestock exclosures at the junction of 
Forest Road 8184A and Corduroy Creek (Frey 2011, pp. 104-105; ADGF 
2012, entire, 2012a, p. 4). In 2011, the Wallow Fire burned much of 
this area, and surveys during 2012 continued to detect New Mexico 
meadow jumping mice (ADGF 2012a, p. 4). The features essential to the 
conservation of this species may require special management 
considerations or protection to reduce the following threats: severe 
wildland fires, grazing, floods, and the reduction in the distribution 
and abundance of beaver ponds. The occupied area is centered around the 
capture location plus an additional 0.8-km (0.5-mi) segment upstream 
and downstream of this area where the physical and biological features 
are found. The remaining unoccupied areas within Subunit 5-G are found 
both upstream and downstream of the occupied area, and are considered 
essential to the conservation of the New Mexico meadow jumping mouse 
(as described in the Unit Description introduction section above).
Subunit 5-H; Campbell Blue Creek
    Subunit 5-H consists of 102 ha (253 ac) along 4.8 km (3.0 mi) of 
Campbell Blue Creek on private lands and areas owned by the Forest 
Service. The proposed subunit begins at the confluence with Cat Creek 
along Forest Road 281 and extends downstream to the confluence with 
Turkey Creek.
    Based upon multiple captures of New Mexico meadow jumping mice 
since 2008 (Frey 2011, p. 101), approximately 0.008 ha (0.02 ac) within 
this unit on Forest Service lands in Arizona are considered occupied at 
the time of listing. The occupied area is located within a livestock 
exclosure 13 km (8 mi) north of the community of Blue (Frey 2011, p. 
101). In 2011, the Wallow Fire burned much of this area, and surveys 
during 2012 did not detect New Mexico meadow jumping mice (ADGF 2012, 
entire, 2012a, p. 2). However, until multiple years of surveys 
determine that the population has been extirpated, we consider this 
area within the geographical area occupied by the New Mexico meadow 
jumping mouse at the time of listing. The features essential to the 
conservation of this species may require special management 
considerations or protection to reduce the following threats: severe 
wildland fires, grazing, floods, and the reduction in the distribution 
and abundance of beaver ponds. The occupied area is centered around the 
capture location plus an additional 0.8-km (0.5-mi) segment upstream 
and downstream of this area where the physical and biological features 
are found. The remaining unoccupied areas within Subunit 5-H are found 
both upstream and downstream of the occupied area, and are considered 
essential to the conservation of the New Mexico meadow jumping mouse 
(as described

[[Page 37344]]

in the Unit Description introduction section above).

Unit 6: Middle Rio Grande

    Unit 5 consists of 294 ha (727 ac) of streams, ditches, and canals 
within three subunits of streams on lands owned by Isleta Pueblo, 
Bernalillo County; Ohkay Owingeh, Rio Arriba County; and the Service's 
Bosque del Apache NWR, Socorro County, New Mexico. Areas proposed for 
critical habitat for the New Mexico meadow jumping mouse in this unit 
incorporate the only habitat believed to be occupied (Bosque del Apache 
NWR) by the subspecies within the middle Rio Grande with the capability 
to support the breeding and reproduction of the species.
    Because Bosque del Apache NWR is the only locality within the 
middle Rio Grande considered still in existence (Frey and Wright 2012), 
we do not believe one population is sufficient to provide for the 
conservation of the species. A designation limited to the range that we 
consider occupied by the species within the middle Rio Grande would be 
inadequate to recover the species within the unit. We have determined 
additional subunits are essential to the conservation of the species 
because, if necessary, these additional areas have the potential to 
provide for the reintroduction and reestablishment of New Mexico meadow 
jumping mouse to support recovery. As such, we are proposing two 
additional subunits that were historically occupied, but where presence 
of the New Mexico meadow jumping mouse is currently unknown.
Subunit 6-A; Isleta Pueblo
    Subunit 6-A consists of 43 ha (105 ac) along 3.7 km (2.3 mi) of 
ditches, canals, and marshes on lands owned by Isleta Pueblo. There are 
two segments within this subunit. One segment begins at the confluence 
of the Isleta Return Channel and the Rio Grande and extends north about 
0.5 km (0.3 mi), then heads west about 30 m (100 ft), and finally heads 
south about 1.6 km (1 mi) to the end of Isleta Marsh paralleling New 
Mexico Highway 314. The other segment begins about 0.8 km (0.5 mi) 
south of Highway 25 and extends about 1.6 km (1.0 mi) along the marsh 
where it terminates at the railroad crossing, just west of the Rio 
Grande.
    Much of the habitat was historically occupied with individuals 
detected as recently as 1988 (Morrison 1988, pp. 22-27; Frey 2006c, 
entire); however, no New Mexico meadow jumping mice surveys have been 
conducted recently. The entire subunit is considered unoccupied at the 
time of listing. All of the areas within Subunit 6-A are considered 
essential to the conservation of the New Mexico meadow jumping mouse 
(as described in the Unit Description introduction section above).
    We will also consider our partnership with this Tribe and evaluate 
the conservation planning and management that occurs for potential 
exclusion under section 4(b)(2) of the Act (see ``Exclusions'' below).
Subunit 6-B; Ohkay Owingeh
    Subunit 6-B consists of 51 ha (125 ac) along 4.8 km (3.0 mi) of 
ditches, canals, and marshes on lands owned by Ohkay Owingeh. There are 
two segments within this subunit. The first segment begins at the 
junction of New Mexico Highway 291 and immediately west of the middle 
Rio Grande, generally follows riparian areas, and terminates about 0.6 
km (0.4 mi) southeast of Guique, New Mexico. The second segment begins 
near San Juan Lakes, east of the Rio Grande 0.08 km (0.05 mi) east of 
Fishpond Road and extends about 0.4 km (0.25 mi) southeast where it 
heads northwest about 0.9 km (0.6 mi) through a series of ponds and 
marshes, paralleling the eastern edge of the fishing pond. Much of the 
habitat was historically occupied with individuals detected as recently 
as 1988 (Morrison 1988, pp. 28-35, Frey 2006c, entire); however, no New 
Mexico meadow jumping mice were captured during surveys conducted 
recently (Morrison 2012, entire). The entire subunit is considered 
unoccupied at the time of listing. All of the areas within Subunit 6-B 
are considered essential to the conservation of the New Mexico meadow 
jumping mouse (as described in the Unit Description introduction 
section above).
    We will also consider our partnership with this Tribe and evaluate 
the conservation planning and management that occurs for potential 
exclusion under section 4(b)(2) of the Act (see ``Exclusions'').
Subunit 6-C; Bosque del Apache National Wildlife Refuge
    Subunit 6-C consists of 201 ha (496 ac) along 29.6 km (18.5 mi) of 
ditches and canals on areas owned by the Service. This subunit includes 
parts of a complex ditch system with associated irrigation of Refuge 
management units, making habitat within this area unique. This subunit 
begins in the northern part of the refuge and generally follows the 
Riverside Canal to the southern end, including a 4.8-km (3.0-mi) 
segment of Socorro-San Antonio Main Canal.
    Based upon multiple captures of the New Mexico meadow jumping mouse 
since 2009 (Frey and Wright 2012, entire), approximately 4.1 ha (10.1 
ac) within this unit on Service lands in New Mexico are considered 
occupied at the time of listing. The occupied area is located along a 
2.7-km (1.7-mi) segment of the Riverside Canal (Frey and Wright 2012, 
entire). The features essential to the conservation of this species may 
require special management considerations or protection to reduce the 
following threats: water use and management, severe wildland fires, and 
thinning, mowing, or removing tamarisk (also known as saltcedar, 
Tamarix ramosissima), decadent stands of willow that are greater than 3 
years old or 1.5 meters (4.9 feet) tall. The occupied area is centered 
around the capture locations plus an additional 0.8-km (0.5-mi) segment 
upstream and downstream of this area where the physical and biological 
features are found. The remaining unoccupied areas within Subunit 6-C 
are found both upstream and downstream of the occupied area, and are 
considered essential to the conservation of the New Mexico meadow 
jumping mouse (as described in the Unit Description introduction 
section above).

Unit 7: Florida River

    Unit 7 consists of 256 ha (634 ac) along 13.6 km (8.4 mi) of the 
Florida River on private lands and an area owned by the Bureau of Land 
Management, La Plata County, Colorado. The unit begins at the 
irrigation diversion structure (Florida Ditch main headgate) of the 
Florida Water Conservancy District about 0.8 km (0.5 mi) northeast of 
the intersection of La Plata County Road 234 and 237 and follows the 
drainage downstream to about 0.16 km (0.1 mi) north of Ranchos Florida 
Road.
    Based upon the capture of two New Mexico meadow jumping mice since 
2007 (Museum of Southwestern Biology 2007; 2007a; Frey 2008c, pp. 42-
45, 56; 2011a, pp. 19, 33), approximately 0.15 ha (0.37 ac) within this 
unit on private lands in Colorado are considered occupied at the time 
of listing. The occupied area is located 0.9 km (0.6 mi) north of 
Highway 160 along the Florida River (Museum of Southwestern Biology 
2007; 2007a; Frey 2008c, pp. 42-45, 56; 2011a, pp. 19, 33). The 
features essential to the conservation of this species may require 
special management considerations or protection to reduce the following 
threats: floods, water use and management, development, and coalbed 
methane. The occupied area is centered around the capture location

[[Page 37345]]

plus an additional 0.8-km (0.5-mi) segment upstream and downstream of 
this area where the physical and biological features are found. The 
remaining unoccupied areas within Unit 7 are found both upstream and 
downstream of the occupied area, and are considered essential to the 
conservation of the New Mexico meadow jumping mouse (as described in 
the Unit Description introduction section above).

Unit 8: Sambrito Creek

    Unit 8 consists of 75 ha (184 ac) along 4.6 km (2.9 mi) of Sambrito 
Creek on private lands and areas owned by the State of Colorado within 
Navajo State Park, near Arboles, Archuleta County, Colorado. There are 
two segments within this unit. One segment begins at Archuleta County 
Road 977, following Sambrito Creek downstream to the headwaters of 
Navajo Reservoir. The second segment starts about 0.3 km (0.2 mi) west 
of the intersection of Colorado Road 977 and 988 and follows the 
drainage about 3.9 km (2.1 mi) through the Sambrito Wetlands Area 
downstream about to the headwaters of Navajo Reservoir.
    Based upon multiple captures of New Mexico meadow jumping mice in 
2012 (Colorado Parks and Wildlife 2012, entire), approximately 0.9 ha 
(2.3 ac) within this unit on State of Colorado lands are considered 
occupied at the time of listing. The occupied area is located 
immediately south of Archuleta County Road 977 along the unnamed 
drainage through the Sambrito Wetlands Areas about 1.8 km (1.1 mi) due 
west of Sambrito Creek (Colorado Parks and Wildlife 2012, entire). The 
features essential to the conservation of this species may require 
special management considerations or protection to reduce the following 
threats: floods, grazing, water use and management, the reduction in 
the distribution and abundance of beaver ponds, development, 
recreation, and coalbed methane. The occupied area is centered around 
the capture location that is about 0.5 km (0.3 mi) south of Archuleta 
County Road 977 plus an additional 0.8-km (0.5-mi) segment upstream and 
downstream of this area where the physical and biological features are 
found. The remaining unoccupied areas within Unit 8 are found both 
upstream and downstream of the occupied area, and are considered 
essential to the conservation of the New Mexico meadow jumping mouse 
(as described in the Unit Description introduction section above).

Effects of Critical Habitat Designation

Section 7 Consultation

    Section 7(a)(2) of the Act requires Federal agencies, including the 
Service, to ensure that any action they fund, authorize, or carry out 
is not likely to jeopardize the continued existence of any endangered 
species or threatened species or result in the destruction or adverse 
modification of designated critical habitat of such species. In 
addition, section 7(a)(4) of the Act requires Federal agencies to 
confer with the Service on any agency action that is likely to 
jeopardize the continued existence of any species proposed to be listed 
under the Act or result in the destruction or adverse modification of 
proposed critical habitat.
    Decisions by the 5th and 9th Circuit Courts of Appeals have 
invalidated our regulatory definition of ``destruction or adverse 
modification'' (50 CFR 402.02) (see Gifford Pinchot Task Force v. U.S. 
Fish and Wildlife Service, 378 F. 3d 1059 (9th Cir. 2004) and Sierra 
Club v. U.S. Fish and Wildlife Service et al., 245 F.3d 434, 442 (5th 
Cir. 2001)), and we do not rely on this regulatory definition when 
analyzing whether an action is likely to destroy or adversely modify 
critical habitat. Under the statutory provisions of the Act, we 
determine destruction or adverse modification on the basis of whether, 
with implementation of the proposed Federal action, the affected 
critical habitat would continue to serve its intended conservation role 
for the species.
    If a Federal action may affect a listed species or its critical 
habitat, the responsible Federal agency (action agency) must enter into 
consultation with us. Examples of actions that are subject to the 
section 7 consultation process are actions on State, tribal, local, or 
private lands that require a Federal permit (such as a permit from the 
U.S. Army Corps of Engineers under section 404 of the Clean Water Act 
(33 U.S.C. 1251 et seq.) or a permit from the Service under section 10 
of the Act) or that involve some other Federal action (such as funding 
from the Federal Highway Administration, Federal Aviation 
Administration, or the Federal Emergency Management Agency). Federal 
actions not affecting listed species or critical habitat, and actions 
on State, tribal, local, or private lands that are not federally funded 
or authorized, do not require section 7 consultation.
    As a result of section 7 consultation, we document compliance with 
the requirements of section 7(a)(2) through our issuance of:
    (1) A concurrence letter for Federal actions that may affect, but 
are not likely to adversely affect, listed species or critical habitat; 
or
    (2) A biological opinion for Federal actions that may affect, or 
are likely to adversely affect, listed species or critical habitat.
    When we issue a biological opinion concluding that a project is 
likely to jeopardize the continued existence of a listed species and/or 
destroy or adversely modify critical habitat, we provide reasonable and 
prudent alternatives to the project, if any are identifiable, that 
would avoid the likelihood of jeopardy and/or destruction or adverse 
modification of critical habitat. We define ``reasonable and prudent 
alternatives'' (at 50 CFR 402.02) as alternative actions identified 
during consultation that:
    (1) Can be implemented in a manner consistent with the intended 
purpose of the action,
    (2) Can be implemented consistent with the scope of the Federal 
agency's legal authority and jurisdiction,
    (3) Are economically and technologically feasible, and
    (4) Would, in the Director's opinion, avoid the likelihood of 
jeopardizing the continued existence of the listed species and/or avoid 
the likelihood of destroying or adversely modifying critical habitat.
    Reasonable and prudent alternatives can vary from slight project 
modifications to extensive redesign or relocation of the project. Costs 
associated with implementing a reasonable and prudent alternative are 
similarly variable.
    Regulations at 50 CFR 402.16 require Federal agencies to reinitiate 
consultation on previously reviewed actions in instances where we have 
listed a new species or subsequently designated critical habitat that 
may be affected and the Federal agency has retained discretionary 
involvement or control over the action (or the agency's discretionary 
involvement or control is authorized by law). Consequently, Federal 
agencies sometimes may need to request reinitiation of consultation 
with us on actions for which formal consultation has been completed, if 
those actions with discretionary involvement or control may affect 
subsequently listed species or designated critical habitat.

Application of the ``Adverse Modification'' Standard

    The key factor related to the adverse modification determination is 
whether, with implementation of the proposed Federal action, the 
affected critical

[[Page 37346]]

habitat would continue to serve its intended conservation role for the 
species. Activities that may destroy or adversely modify critical 
habitat are those that alter the physical or biological features to an 
extent that appreciably reduces the conservation value of critical 
habitat for the New Mexico meadow jumping mouse. As discussed above, 
the role of critical habitat is to support life-history needs of the 
species and provide for the conservation of the species.
    Section 4(b)(8) of the Act requires us to briefly evaluate and 
describe, in any proposed or final regulation that designates critical 
habitat, activities involving a Federal action that may destroy or 
adversely modify such habitat, or that may be affected by such 
designation.
    Activities that may affect critical habitat, when carried out, 
funded, or authorized by a Federal agency, should result in 
consultation for the New Mexico meadow jumping mouse. These activities 
include, but are not limited to:
    (1) Any activity that destroys, modifies, alters, or removes the 
herbaceous riparian vegetation that comprises the species' habitat, as 
described in this proposed rule or within the May 2013 SSA Report, 
especially if these activities occur during the New Mexico meadow 
jumping mouse's active season. Such activities could include, but are 
not limited to: Domestic livestock grazing; land clearing or mowing; 
activities associated with construction for roads, bridges, pipelines, 
or bank stabilization; residential or commercial development; channel 
alteration; timber harvest; prescribed fires; off-road vehicle 
activity; recreational use; the removal of beaver (excluding irrigation 
ditches and canals); and other alterations of watersheds and 
floodplains. These activities may affect the physical or biological 
features of critical habitat for the New Mexico meadow jumping mouse, 
by removing sources of food, shelter, nesting or hibernation sites, or 
otherwise impacting habitat essential for completion of its life 
history.
    (2) Any activity that results in changes in the hydrology of the 
unit, including modification to any stream or water body that results 
in the removal or destruction of herbaceous riparian vegetation in any 
stream or water body. Such activities that could cause these effects 
include, but are not limited to, water diversions, groundwater pumping, 
watershed degradation, construction or destruction of dams or 
impoundments, developments or `improvements' at a spring, 
channelization, dredging, road and bridge construction, destruction of 
riparian or wetland vegetation, and other activities resulting in the 
draining or inundation of a unit.
    (3) Any activity (e.g., instream dredging, impoundment, water 
diversion or withdrawal, channelization, discharge of fill material) 
that detrimentally alters natural processes in a unit, including 
changes to inputs of water, sediment, and nutrients, or any activity 
that significantly and detrimentally alters water quantity in the unit.
    (4) Any activity that could lead to the introduction, expansion, or 
increased density of an exotic plant or animal species that is 
detrimental to the New Mexico meadow jumping mouse and to its habitat.

Exemptions

Application of Section 4(a)(3) of the Act

    The Sikes Improvement Act of 1997 (Sikes Act) (16 U.S.C. 670a) 
required each military installation that includes land and water 
suitable for the conservation and management of natural resources to 
complete an integrated natural resources management plan (INRMP) by 
November 17, 2001. An INRMP integrates implementation of the military 
mission of the installation with stewardship of the natural resources 
found on the base. Each INRMP includes:
    (1) An assessment of the ecological needs of the installation, 
including the need to provide for the conservation of listed species;
    (2) A statement of goals and priorities;
    (3) A detailed description of management actions to be implemented 
to provide for these ecological needs; and
    (4) A monitoring and adaptive management plan.
    Among other things, each INRMP must, to the extent appropriate and 
applicable, provide for fish and wildlife management; fish and wildlife 
habitat enhancement or modification; wetland protection, enhancement, 
and restoration where necessary to support fish and wildlife; and 
enforcement of applicable natural resource laws.
    The National Defense Authorization Act for Fiscal Year 2004 (Pub. 
L. 108-136) amended the Act to limit areas eligible for designation as 
critical habitat. Specifically, section 4(a)(3)(B)(i) of the Act (16 
U.S.C. 1533(a)(3)(B)(i)) now provides: ``The Secretary shall not 
designate as critical habitat any lands or other geographic areas owned 
or controlled by the Department of Defense, or designated for its use, 
that are subject to an integrated natural resources management plan 
prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if the 
Secretary determines in writing that such plan provides a benefit to 
the species for which critical habitat is proposed for designation.''
    There are no Department of Defense lands within the proposed 
critical habitat designation for the New Mexico meadow jumping mouse; 
therefore, we do not anticipate exempting any areas under section 
4(a)(3)(B)(i) of the Act.

Exclusions

Application of Section 4(b)(2) of the Act

    Section 4(b)(2) of the Act states that the Secretary shall 
designate and make revisions to critical habitat on the basis of the 
best available scientific data after taking into consideration the 
economic impact, national security impact, and any other relevant 
impact of specifying any particular area as critical habitat. The 
Secretary may exclude an area from critical habitat if he determines 
that the benefits of such exclusion outweigh the benefits of specifying 
such area as part of the critical habitat, unless he determines, based 
on the best scientific data available, that the failure to designate 
such area as critical habitat will result in the extinction of the 
species. In making that determination, the statute on its face, as well 
as the legislative history, are clear that the Secretary has broad 
discretion regarding which factor(s) to use and how much weight to give 
to any factor.
    Under section 4(b)(2) of the Act, we may exclude an area from 
designated critical habitat based on economic impacts, impacts on 
national security, or any other relevant impacts. In considering 
whether to exclude a particular area from the designation, we identify 
the benefits of including the area in the designation, identify the 
benefits of excluding the area from the designation, and evaluate 
whether the benefits of exclusion outweigh the benefits of inclusion. 
If the analysis indicates that the benefits of exclusion outweigh the 
benefits of inclusion, the Secretary may exercise his discretion to 
exclude the area only if such exclusion would not result in the 
extinction of the species.

Exclusions Based on Economic Impacts

    Under section 4(b)(2) of the Act, we consider the economic impacts 
of specifying any particular area as critical habitat. In order to 
consider economic impacts, we are preparing an analysis of the economic 
impacts of the proposed critical habitat designation and related 
factors. Potential land use sectors that

[[Page 37347]]

may be affected by New Mexico meadow jumping mouse critical habitat 
designation include domestic livestock grazing, activities associated 
with construction or improvement of roads, bridges, pipelines, or bank 
stabilization; residential or commercial development; recreation; 
prescribed burns; and irrigation water use and management.
    During the development of a final designation, we will consider 
economic impacts, public comments, and other new information, and areas 
may be excluded from the final critical habitat designation under 
section 4(b)(2) of the Act and our implementing regulations at 50 CFR 
424.19.

Exclusions Based on National Security Impacts

    Under section 4(b)(2) of the Act, we consider whether there are 
lands owned or managed by the Department of Defense (DOD) or lands 
where a national security impact might exist. In preparing this 
proposal, we have determined that the lands within the proposed 
designation of critical habitat for the New Mexico meadow jumping mouse 
are not owned or managed by the DOD. Currently, there are no areas 
proposed for exclusion based on impacts on national security.

Exclusions Based on Other Relevant Impacts

    Under section 4(b)(2) of the Act, we consider any other relevant 
impacts, in addition to economic impacts and impacts on national 
security. We consider a number of factors including whether the 
landowners have developed any HCPs or other management plans for the 
area, or whether there are conservation partnerships that would be 
encouraged by designation of, or exclusion from, critical habitat. In 
addition, we look at Tribal management in recognition of their 
capability to appropriately manage their own resources, and consider 
the government-to-government relationship of the United States with 
Tribal entities. We also consider any social impacts that might occur 
because of the designation.
    When we evaluate the existence of a conservation plan when 
considering the benefits of exclusion, we consider a variety of 
factors, including but not limited to, whether the plan is finalized; 
how it provides for the conservation of the essential physical or 
biological features; whether there is a reasonable expectation that the 
conservation management strategies and actions contained in a 
management plan will be implemented into the future; whether the 
conservation strategies in the plan are likely to be effective; and 
whether the plan contains a monitoring program or adaptive management 
to ensure that the conservation measures are effective and can be 
adapted in the future in response to new information.
    In preparing this proposal, we have determined that there are 
currently no HCPs for the New Mexico meadow jumping mouse. As detailed 
above, the proposed designation includes areas within two Native 
American Pueblos that are considered unoccupied by New Mexico meadow 
jumping mice, but are essential for the conservation of the species. 
Therefore, we have proposed designation of critical habitat for the New 
Mexico meadow jumping mouse on tribal lands. We have begun government-
to-government consultation with these tribes, and will continue to do 
so throughout the public comment period and during development of the 
final designation of critical habitat for the New Mexico meadow jumping 
mouse. We will consider these areas for exclusion from the final 
critical habitat designation to the extent consistent with the 
requirements of section 4(b)(2) of the Act. At this time, we are not 
proposing the exclusion of any Tribal areas in this proposed critical 
habitat designation. However, we specifically solicit comments on the 
inclusion or exclusion of such areas. In the paragraphs below, we 
identify lands that we are considering for exclusion under section 
4(b)(2) of the Act.
Tribal Management Plans and Partnerships
    Ohkay Owingeh (San Juan Pueblo) and Isleta Pueblo contain segments 
of the Rio Grande in Rio Arriba and Bernalillo Counties, New Mexico, 
respectively, which are essential to the conservation of the New Mexico 
meadow jumping mouse. These river segments occur within the proposed 
Rio Grande Critical Habitat Unit. We sent notification letters in 
November 2011 to both Tribes describing our listing process. We will 
coordinate with these Tribes and examine what New Mexico meadow jumping 
mouse conservation actions, management plans, and commitments and 
assurances occur on these lands for potential exclusion from the final 
designation of New Mexico meadow jumping mouse habitat.
Isleta Pueblo
    Isleta Pueblo contains proposed New Mexico meadow jumping mouse 
critical habitat along the Rio Grande within Bernalillo County, New 
Mexico. The Isleta Pueblo has conducted a variety of voluntary 
measures, restoration projects, and management actions to conserve 
riparian vegetation, including not allowing cattle to graze within the 
bosque (riparian areas) and protecting riparian habitat from fire, 
maintaining native vegetation, and preventing habitat fragmentation 
(Service 2005; 70 FR 60955; Pueblo of Isleta 2005, entire). Because of 
the voluntary measures undertaken, we will consider excluding Isleta 
Pueblo lands from the final designation of New Mexico meadow jumping 
mouse critical habitat under section 4(b)(2) of the Act.
Ohkay Owingeh (San Juan Pueblo)
    Ohkay Owingeh contains proposed New Mexico meadow jumping mouse 
critical habitat along the Rio Grande within Rio Arriba County, New 
Mexico. The Pueblo has conducted a variety of voluntary measures, 
restoration projects, and management actions to conserve the New Mexico 
meadow jumping mouse and its habitat on their lands. The Pueblo has 
engaged in riparian vegetation and wetland improvement projects, while 
managing to reduce the occurrence of wildfire due to the abundance of 
exotic flammable riparian vegetation, including using Tribal Wildlife 
Grants in both 2004 and 2006 to restore riparian and wetland habitat to 
benefit the Southwestern willow flycatcher (Empidonax traillii 
extimus), bald eagle (Haliaeetus leucocephalus), and other riparian 
species on 36.4 ha (90 ac) of the Rio Grande (Service 2007a, p. 42; 
Service 2005, 70 FR 60963). Funding for another 10.9 ha (27 ac) of 
riparian and wetland restoration was provided in 2007 (Service 2012f, 
p. 12). The Pueblo received an additional Tribal Wildlife Grant in 2011 
to conduct surveys and restore habitat for the New Mexico meadow New 
Mexico meadow jumping mouse (Service 2012f, p. 12). The long-term goal 
of the Pueblo's riparian management is to implement innovative 
restoration techniques, decrease fire hazards by restoring native 
vegetation, share information with other restoration practitioners, 
utilize restoration projects in the education of the Tribal community 
and surrounding community, and provide a working and training 
environment for the people of the Pueblo. Because of the voluntary 
measures undertaken, we will consider excluding Ohkay Owingeh (San Juan 
Pueblo) lands from the final designation of New Mexico meadow jumping 
mouse critical habitat under section 4(b)(2) of the Act.
    A final determination on whether the Secretary will exercise his 
discretion to exclude any of these areas from critical habitat for the 
New Mexico meadow jumping mouse will be made when we publish the final 
rule designating critical habitat. We will take into

[[Page 37348]]

account public comments and carefully weigh the benefits of exclusion 
versus inclusion of these areas. We may also consider areas not 
identified above for exclusion from the final critical habitat 
designation based on information we may receive during the preparation 
of the final rule (e.g., management plans for additional areas).

Peer Review

    In accordance with our joint policy on peer review published in the 
Federal Register on July 1, 1994 (59 FR 34270), we will seek the expert 
opinions of at least three appropriate and independent specialists 
regarding this proposed rule. The purpose of peer review is to ensure 
that our listing determination and critical habitat designation are 
based on scientifically sound data, assumptions, and analyses. We have 
invited these peer reviewers to comment during this public comment 
period.
    We will consider all comments and information received during this 
comment period on this proposed rule during our preparation of a final 
determination. Accordingly, the final decision may differ from this 
proposal.

Public Hearings

    Section 4(b)(5) of the Act provides for one or more public hearings 
on this proposal, if requested. Requests must be received within 45 
days after the date of publication of this proposed rule in the Federal 
Register. Such requests must be sent to the address shown in FOR 
FURTHER INFORMATION CONTACT. We will schedule public hearings on this 
proposal, if any are requested, and announce the dates, times, and 
places of those hearings, as well as how to obtain reasonable 
accommodations, in the Federal Register and local newspapers at least 
15 days before the hearing.

Required Determinations

Regulatory Planning and Review--Executive Orders 12866 and 13563

    Executive Order 12866 provides that the Office of Information and 
Regulatory Affairs (OIRA) in the Office of Management and Budget will 
review all significant rules. The Office of Information and Regulatory 
Affairs has determined that this rule is not significant.
    Executive Order 13563 reaffirms the principles of Executive Order 
12866 while calling for improvements in the nation's regulatory system 
to promote predictability, to reduce uncertainty, and to use the best, 
most innovative, and least burdensome tools for achieving regulatory 
ends. The executive order directs agencies to consider regulatory 
approaches that reduce burdens and maintain flexibility and freedom of 
choice for the public where these approaches are relevant, feasible, 
and consistent with regulatory objectives. Executive Order 13563 
emphasizes further that regulations must be based on the best available 
science and that the rulemaking process must allow for public 
participation and an open exchange of ideas. We have developed this 
rule in a manner consistent with these requirements.

Regulatory Flexibility Act (5 U.S.C. 601 et seq.)

    Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.) as 
amended by the Small Business Regulatory Enforcement Fairness Act 
(SBREFA) of 1996 (5 U.S.C 801 et seq.), whenever an agency must publish 
a notice of rulemaking for any proposed or final rule, it must prepare 
and make available for public comment a regulatory flexibility analysis 
that describes the effects of the rule on small entities (small 
businesses, small organizations, and small government jurisdictions). 
However, no regulatory flexibility analysis is required if the head of 
the agency certifies the rule will not have a significant economic 
impact on a substantial number of small entities. The SBREFA amended 
the RFA to require Federal agencies to provide a certification 
statement of the factual basis for certifying that the rule will not 
have a significant economic impact on a substantial number of small 
entities.
    According to the Small Business Administration, small entities 
include small organizations such as independent nonprofit 
organizations; small governmental jurisdictions, including school 
boards and city and town governments that serve fewer than 50,000 
residents; and small businesses (13 CFR 121.201). Small businesses 
include such businesses as manufacturing and mining concerns with fewer 
than 500 employees, wholesale trade entities with fewer than 100 
employees, retail and service businesses with less than $5 million in 
annual sales, general and heavy construction businesses with less than 
$27.5 million in annual business, special trade contractors doing less 
than $11.5 million in annual business, and forestry and logging 
operations with fewer than 500 employees and annual business less than 
$7 million. To determine whether small entities may be affected, we 
will consider the types of activities that might trigger regulatory 
impacts under this designation as well as types of project 
modifications that may result. In general, the term ``significant 
economic impact'' is meant to apply to a typical small business firm's 
business operations.
    Importantly, the incremental impacts of a rule must be both 
significant and substantial to prevent certification of the rule under 
the RFA and to require the preparation of an initial regulatory 
flexibility analysis. If a substantial number of small entities are 
affected by the proposed critical habitat designation, but the per-
entity economic impact is not significant, the Service may certify. 
Likewise, if the per-entity economic impact is likely to be 
significant, but the number of affected entities is not substantial, 
the Service may also certify.
    The Service's current understanding of recent case law is that 
Federal agencies are only required to evaluate the potential impacts of 
rulemaking on those entities directly regulated by the rulemaking; 
therefore, they are not required to evaluate the potential impacts to 
those entities not directly regulated. The designation of critical 
habitat for an endangered or threatened species only has a regulatory 
effect where a Federal action agency is involved in a particular action 
that may affect the designated critical habitat. Under these 
circumstances, only the Federal action agency is directly regulated by 
the designation, and, therefore, consistent with the Service's current 
interpretation of RFA and recent case law, the Service may limit its 
evaluation of the potential impacts to those identified for Federal 
action agencies. Under this interpretation, there is no requirement 
under the RFA to evaluate the potential impacts to entities not 
directly regulated, such as small businesses. However, Executive Orders 
12866 and 13563 direct Federal agencies to assess costs and benefits of 
available regulatory alternatives in quantitative (to the extent 
feasible) and qualitative terms. Consequently, it is the current 
practice of the Service to assess to the extent practicable these 
potential impacts if sufficient data are available, whether or not this 
analysis is believed by the Service to be strictly required by the RFA. 
In other words, while the effects analysis required under the RFA is 
limited to entities directly regulated by the rulemaking, the effects 
analysis under the Act, consistent with the E.O. 12866 regulatory 
analysis requirements, can take into consideration impacts to both 
directly and indirectly impacted entities, where practicable and 
reasonable.
    In conclusion, we believe that, based on our interpretation of 
directly regulated entities under the RFA and relevant case law, this 
designation of

[[Page 37349]]

critical habitat will only directly regulate Federal agencies which are 
not by definition small business entities. And as such, we certify 
that, if promulgated, this designation of critical habitat would not 
have a significant economic impact on a substantial number of small 
business entities. Therefore, an initial regulatory flexibility 
analysis is not required. However, though not necessarily required by 
the RFA, in our draft economic analysis for this proposal we will 
consider and evaluate the potential effects to third parties that may 
be involved with consultations with Federal action agencies related to 
this action.

Energy Supply, Distribution, or Use--Executive Order 13211

    Executive Order 13211 (Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use) requires 
agencies to prepare Statements of Energy Effects when undertaking 
certain actions. A small portion of an existing gas pipeline is within 
proposed critical habitat; however, we do not expect the designation of 
this proposed critical habitat to significantly affect energy supplies, 
distribution, or use. Therefore, this action is not a significant 
energy action, and no Statement of Energy Effects is required. However, 
we will further evaluate this issue as we conduct our economic 
analysis, and review and revise this assessment as warranted.

Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)

    In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501 
et seq.), we make the following findings:
    (1) This rule will not produce a Federal mandate. In general, a 
Federal mandate is a provision in legislation, statute, or regulation 
that would impose an enforceable duty upon State, local, or tribal 
governments, or the private sector, and includes both ``Federal 
intergovernmental mandates'' and ``Federal private sector mandates.'' 
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal 
intergovernmental mandate'' includes a regulation that ``would impose 
an enforceable duty upon State, local, or tribal governments'' with two 
exceptions. It excludes ``a condition of Federal assistance.'' It also 
excludes ``a duty arising from participation in a voluntary Federal 
program,'' unless the regulation ``relates to a then-existing Federal 
program under which $500,000,000 or more is provided annually to State, 
local, and tribal governments under entitlement authority,'' if the 
provision would ``increase the stringency of conditions of assistance'' 
or ``place caps upon, or otherwise decrease, the Federal Government's 
responsibility to provide funding,'' and the State, local, or tribal 
governments ``lack authority'' to adjust accordingly. At the time of 
enactment, these entitlement programs were: Medicaid; Aid to Families 
with Dependent Children work programs; Child Nutrition; Food Stamps; 
Social Services Block Grants; Vocational Rehabilitation State Grants; 
Foster Care, Adoption Assistance, and Independent Living; Family 
Support Welfare Services; and Child Support Enforcement. ``Federal 
private sector mandate'' includes a regulation that ``would impose an 
enforceable duty upon the private sector, except (i) a condition of 
Federal assistance or (ii) a duty arising from participation in a 
voluntary Federal program.''
    The designation of critical habitat does not impose a legally 
binding duty on non-Federal Government entities or private parties. 
Under the Act, the only regulatory effect is that Federal agencies must 
ensure that their actions do not destroy or adversely modify critical 
habitat under section 7. While non-Federal entities that receive 
Federal funding, assistance, or permits, or that otherwise require 
approval or authorization from a Federal agency for an action, may be 
indirectly impacted by the designation of critical habitat, the legally 
binding duty to avoid destruction or adverse modification of critical 
habitat rests squarely on the Federal agency. Furthermore, to the 
extent that non-Federal entities are indirectly impacted because they 
receive Federal assistance or participate in a voluntary Federal aid 
program, the Unfunded Mandates Reform Act would not apply, nor would 
critical habitat shift the costs of the large entitlement programs 
listed above onto State governments.
    (2) We lack the available economic information to determine if a 
Small Government Agency Plan is required. Therefore, we defer this 
finding until completion of the draft economic analysis is prepared 
under section 4(b)(2) of the Act.

Takings--Executive Order 12630

    In accordance with Executive Order 12630 (Government Actions and 
Interference with Constitutionally Protected Private Property Rights), 
we will analyze the potential takings implications of designating 
critical habitat for the New Mexico meadow jumping mouse in a takings 
implications assessment. Critical habitat designation does not affect 
landowner actions that do not require Federal funding or permits, nor 
does it preclude development of habitat conservation programs or 
issuance of incidental take permits to permit actions that do require 
Federal funding or permits to go forward. We have not yet completed the 
economic analysis for this proposed rule. Once the economic analysis is 
available, we will review and revise this preliminary assessment as 
warranted, and prepare a Takings Implication Assessment.

Federalism--Executive Order 13132

    In accordance with Executive Order 13132 (Federalism), this 
proposed rule does not have significant Federalism effects. A 
Federalism assessment is not required. In keeping with Department of 
the Interior policy, we requested information from, and coordinated 
development of, this proposed critical habitat designation with 
appropriate State resource agencies. The designation of critical 
habitat in geographic areas currently occupied by the New Mexico meadow 
jumping mouse imposes no additional restrictions to those currently in 
place and, therefore, has little incremental impact on State and local 
governments and their activities. The designation may have some benefit 
to these governments because the areas that contain the physical or 
biological features essential to the conservation of the species are 
more clearly defined, and the elements of the features of the habitat 
necessary to the conservation of the species are specifically 
identified. This information does not alter where and what federally 
sponsored activities may occur. However, it may assist local 
governments in long-range planning (rather than having them wait for 
case-by-case section 7 consultations to occur).
    Where State and local governments require approval or authorization 
from a Federal agency for actions that may affect critical habitat, 
consultation under section 7(a)(2) would be required. While non-Federal 
entities that receive Federal funding, assistance, or permits, or that 
otherwise require approval or authorization from a Federal agency for 
an action, may be indirectly impacted by the designation of critical 
habitat, the legally binding duty to avoid destruction or adverse 
modification of critical habitat rests squarely on the Federal agency.

Civil Justice Reform--Executive Order 12988

    In accordance with Executive Order 12988 (Civil Justice Reform), 
the Office of the Solicitor has determined that the

[[Page 37350]]

rule does not unduly burden the judicial system and that it meets the 
requirements of sections 3(a) and 3(b)(2) of the Order. We have 
proposed designating critical habitat in accordance with the provisions 
of the Act. To assist the public in understanding the habitat needs of 
the species, the rule identifies the elements of physical or biological 
features essential to the conservation of the species. The designated 
areas of critical habitat are presented on maps, and the rule provides 
several options for the interested public to obtain more detailed 
location information, if desired.

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)

    This rule does not contain any new collections of information that 
require approval by OMB under the Paperwork Reduction Act of 1995 (44 
U.S.C. 3501 et seq.). This rule will not impose recordkeeping or 
reporting requirements on State or local governments, individuals, 
businesses, or organizations. An agency may not conduct or sponsor, and 
a person is not required to respond to, a collection of information 
unless it displays a currently valid OMB control number.

National Environmental Policy Act (42 U.S.C. 4321 et seq.)

    It is our position that, outside the jurisdiction of the U.S. Court 
of Appeals for the Tenth Circuit, we do not need to prepare 
environmental analyses pursuant to NEPA (42 U.S.C. 4321 et seq.) in 
connection with designating critical habitat under the Act. We 
published a notice outlining our reasons for this determination in the 
Federal Register on October 25, 1983 (48 FR 49244). This position was 
upheld by the U.S. Court of Appeals for the Ninth Circuit (Douglas 
County v. Babbitt, 48 F.3d 1495 (9th Cir. 1995), cert. denied 516 U.S. 
1042 (1996)). However, when the range of the species includes States 
within the Tenth Circuit, such as that of the New Mexico meadow jumping 
mouse, under the Tenth Circuit ruling in Catron County Board of 
Commissioners v. U.S. Fish and Wildlife Service, 75 F.3d 1429 (10th 
Cir. 1996), we will undertake a NEPA analysis for critical habitat 
designation and notify the public of the availability of the draft 
environmental assessment for this proposal when it is finished.

Government-to-Government Relationship With Tribes

    In accordance with the President's memorandum of May 29, 1994 
(Government-to-Government Relations with Native American Tribal 
Governments; 59 FR 22951), Executive Order 13175 (Consultation and 
Coordination With Indian Tribal Governments), and the Department of the 
Interior's manual at 512 DM 2, we readily acknowledge our 
responsibility to communicate meaningfully with recognized Federal 
Tribes on a government-to-government basis. In accordance with 
Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights, 
Federal-Tribal Trust Responsibilities, and the Endangered Species Act), 
we readily acknowledge our responsibilities to work directly with 
tribes in developing programs for healthy ecosystems, to acknowledge 
that tribal lands are not subject to the same controls as Federal 
public lands, to remain sensitive to Indian culture, and to make 
information available to tribes.
    There are tribal lands in New Mexico included in this proposed 
designation of critical habitat that are unoccupied by the species at 
the time of listing that are essential for the conservation of the New 
Mexico meadow jumping mouse. We have begun government-to-government 
consultation with these tribes. We will consider these areas for 
exclusion from the final critical habitat designation to the extent 
consistent with the requirements of section 4(b)(2) of the Act. Isleta 
Pueblo and Ohkay Owingeh are the main tribes affected by this proposed 
rule. We sent notification letters in November 2011 to both tribes 
describing the listing process. We will coordinate with these tribes 
and examine what New Mexico meadow jumping mouse conservation actions, 
management plans, and commitments and assurances occur on these lands 
for potential exclusion from the final designation of New Mexico meadow 
jumping mouse habitat. We will schedule meetings with these tribes and 
any other interested tribes shortly after publication of this proposed 
rule so that we can give them as much time as possible to comment.

Clarity of the Rule

    We are required by Executive Orders 12866 and 12988 and by the 
Presidential Memorandum of June 1, 1998, to write all rules in plain 
language. This means that each rule we publish must:
    (1) Be logically organized;
    (2) Use the active voice to address readers directly;
    (3) Use clear language rather than jargon;
    (4) Be divided into short sections and sentences; and
    (5) Use lists and tables wherever possible.
    If you feel that we have not met these requirements, send us 
comments by one of the methods listed in the ADDRESSES section. To 
better help us revise the rule, your comments should be as specific as 
possible. For example, you should tell us the numbers of the sections 
or paragraphs that are unclearly written, which sections or sentences 
are too long, the sections where you feel lists or tables would be 
useful, etc.

New Mexico Meadow Jumping Mouse (Zapus hudsonius luteus)

    (1) Critical habitat units are depicted for Bernalillo, Colfax, 
Mora, Otero, Rio Arriba, Sandoval, and Socorro Counties, in New Mexico; 
Las Animas, Archuleta, and La Plata Counties, Colorado; and Greenlee 
and Apache Counties, Arizona on the maps below.
    (2) Within these areas, the primary constituent elements of the 
physical or biological features essential to the conservation of the 
New Mexico meadow jumping mouse consist of the following:
    (i) Riparian communities along rivers and streams, springs and 
wetlands, or canals and ditches characterized by one of two wetland 
vegetation community types:
    (A) Persistent emergent herbaceous wetlands dominated by beaked 
sedge (Carex rostrata) or reed canarygrass (Phalaris arundinacea) 
alliances; or
    (B) Scrub-shrub riparian areas that are dominated by willows (Salix 
spp.) or alders (Alnus spp.); and
    (ii) Flowing water that provides saturated soils throughout the New 
Mexico meadow jumping mouse's active season that supports tall (average 
stubble height of herbaceous vegetation of at least 69 cm (27 inches) 
and dense herbaceous riparian vegetation (cover averaging at least 61 
vertical cm (24 inches)) composed primarily of sedges (Carex spp. or 
Schoenoplectus pungens) and forbs, including, but not limited to one or 
more of the following associated species: spikerush (Eleocharis 
macrostachya), beaked sedge (Carex rostrata), reed canarygrass 
(Phalaris arundinacea), rushes (Juncus spp. and Scirpus spp.), and 
numerous species of grasses such as bluegrass (Poa spp.), slender 
wheatgrass (Elymus trachycaulus), brome (Bromus spp.), foxtail barley 
(Hordeum jubatum), or Japanese brome (Bromus japonicas), and forbs such 
as water hemlock (Circuta douglasii), field mint (Mentha arvense), 
asters (Aster spp.), or cutleaf coneflower (Rudbeckia laciniata); and
    (iii) Sufficient areas of 9 to 24 km (5.6 to 15 mi) along a stream, 
ditch, or canal that contain suitable or restorable habitat to support 
movements of individual New Mexico meadow jumping mice; and
    (iv) Include adjacent floodplain and upland areas extending 
approximately 100 m (330 ft) outward from the water's edge (as defined 
by the bankfull stage of streams).
    (3) Critical habitat does not include manmade structures (such as 
buildings, fire lookout stations, runways, roads, and other paved 
areas) and the land on which they are located existing within the legal 
boundaries on the effective date of this rule.
    (4) Critical habitat map units. Units were mapped using the USA 
Contiguous Albers Equal Area Conic USGS version projection. The maps in 
this entry, as modified by any accompanying regulatory text, establish 
the boundaries of the critical habitat designation. The coordinates or 
plot points or both on which each map is based are available to the 
public at the Service's internet site (http://www.fws.gov/southwest/es/NewMexico/), at http://www.regulations.gov at Docket No. FWS-R2-ES-
2013-0014, and at the New Mexico Ecological Services Field Office. You
