[Docket No. FWS-R4-ES-2014-0027; 4500030113]


Endangered and Threatened Wildlife and Plants; 12-Month Finding 
on a Petition To List Symphyotrichum georgianum as an Endangered or 
Threatened Species

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of 12-month petition finding.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a 
12-month finding on a petition to list the Symphyotrichum georgianum 
(Georgia aster) as an endangered species under the Endangered Species 
Act of 1973, as amended (Act). After review of the best available 
scientific and commercial information, we find that listing the S. 
georgianum is not warranted at this time. However, we ask the public to 
submit to us any new information that becomes available concerning the 
threats to the S. georgianum or its habitat at any time.

DATES: The finding announced in this document was made on September 18, 
2014.

ADDRESSES: This finding is available on the Internet at http://www.regulations.gov at Docket Number FWS-R4-ES-2014-0027. Supporting 
documentation we used in preparing this finding is available for public 
inspection, by appointment, during normal business hours at the U.S. 
Fish and Wildlife Service, Asheville Ecological Services Field Office, 
160 Zillicoa St., Asheville, NC 28801. Please submit any new 
information, materials, comments, or questions concerning this finding 
to the above address.

SUPPLEMENTARY INFORMATION:

Background

    Section 4(b)(3)(B) of the Act (16 U.S.C. 1531 et seq.) requires 
that, for any petition to revise the Federal Lists of Endangered and 
Threatened Wildlife and Plants that contains substantial scientific or 
commercial information that listing the species may be warranted, we 
make a finding within 12 months of the date of receipt of the petition. 
In this finding, we determine that the petitioned action is either: (1) 
Not warranted, (2) warranted, or (3) warranted, but the immediate 
proposal of a regulation implementing the petitioned action is 
precluded by other pending proposals to determine whether species are 
endangered or threatened, and expeditious progress is being made to add 
or remove qualified species from the Federal Lists of Endangered and 
Threatened Wildlife and Plants. Section 4(b)(3)(C) of the Act requires 
that we treat a petition for which the requested action is found to be 
warranted but precluded as though resubmitted on the date of such 
finding, that is, requiring a subsequent finding to be made within 12 
months. We must publish these 12-month findings in the Federal 
Register.

Previous Federal Actions

    Symphyotrichum georgianum was added to the Federal list of 
candidate species in 1990 (55 FR 6184) as a category 2 species. 
Category 2 species were those for which there was some evidence of 
vulnerability, but for which additional biological information was 
needed to support a proposed rule to list as endangered or threatened. 
Candidate categories were discontinued in 1996 (61 FR 7596) in favor of 
maintaining a list that only represented those species for which we 
have on file sufficient information on biological vulnerability and 
threats to support a proposal to list as endangered or threatened, but 
for which immediate preparation and publication of a proposal is 
precluded by higher priority listing actions. At that time, S. 
georgianum was removed from the candidate species list. In 1999, we 
returned S. georgianum to the candidate species list (64 FR 57534), and 
it has remained on the candidate list since that time. In the 2007 
Candidate Notice of Review (CNOR) (72 FR 69034), the Service downgraded 
the species' listing priority number from 5 (magnitude of threat = 
high; immediacy of threat = nonimminent) to 8 (magnitude of threat = 
moderate; immediacy of threat = imminent) due to an increase in the 
number of known populations of S. georgianum and a corresponding 
reduction in the magnitude of threats.
    On May 11, 2004, we received a petition, dated May 4, 2004, from 
the Center for Biological Diversity, requesting that Symphyotrichum 
georgianum be listed as an endangered species under the Act. Included 
in the petition was supporting information regarding the species' 
taxonomy and ecology, historical and current distribution, present 
status, and actual and potential causes of decline.
    The standard for making a 12-month warranted but precluded finding 
on a petition to list a species is identical to our standard for making 
a species a candidate for listing. All candidate species identified 
through our own initiative already have received the equivalent of 
substantial 90-day and warranted-but-precluded 12-month findings. 
Nevertheless, we review the status of the newly petitioned candidate 
species and through the CNOR publish specific section 4(b)(3) findings 
(i.e., substantial 90-day and warranted-but-precluded 12-month 
findings) in response to the petitions to list these candidate species. 
We publish these findings as part of the first CNOR following receipt 
of the petition. At the time we received the petition, Symphyotrichum 
georgianum was already on the candidate species list. Therefore, we had 
determined it was warranted for listing but precluded by higher 
priority listing actions. We reviewed the status of S. georgianum in 
every CNOR since the petition was received in 2004.
    Under the 2011 Multi-District Litigation (MDL) settlement 
agreements, the Service agreed to systematically, over a period of 6 
years, review and address the needs of 251 candidate species to 
determine if they should be added to the Federal Lists of Endangered 
and Threatened Wildlife and Plants. Symphyotrichum georgianum was on 
that list of candidate species. Therefore, the Service is making this 
finding at this time in order to comply with the conditions outlined in 
the MDL agreement.
    This notice constitutes a new 12-month finding and listing 
determination for Symphyotrichum georgianum and supersedes all previous 
findings.

Species Information

    Symphyotrichum georgianum is a flowering plant with large heads, 5 
centimeters (cm) (2 inches (in)) across (containing numerous flowers), 
with dark purple rays up to 2.5 cm (0.9 in) long, and thick, lanceolate 
(narrow, and tapering toward the apex of the leaf) to oblanceolate 
(having a rounded apex and a tapering base), scabrous (having small 
raised dots, scales, or points), clasping leaves. Flowering occurs from 
early October to mid-November. Disk flowers are white fading to a light 
or dull lavender, tan or white as they mature, resulting in a 
difference between colors of early and mature disk corollas (the inner 
envelope of floral leaves of a flower). The ribbed achenes

[[Page 56042]]

(small, dry, one-seeded fruit) are up to 4 millimeters (0.1 in) long, 
with evenly distributed spreading trichomes (small hairs from the outer 
layer of a plant). Symphyotrichum georgianum can be distinguished from 
the similar S. patens by its dark purple rays (compared to the light 
lavender rays of S. patens), and white to lavender disk flowers 
(compared to the yellow disk flowers of S. patens) (Weakley 2011, p. 
968).
    Various species of butterflies and bumblebees have been observed 
pollinating the flowers, but these have not yet been identified to 
species (Matthews 1993, p. 21). The main mode of reproduction is 
vegetative. Plants are usually colonial, with one to two stems arising 
from each underground part.

Taxonomy and Species Description

    Alexander initially described the species as Aster georgianus based 
on a specimen collected by Cuthbert in 1898 from Augusta (Richmond 
County), Georgia (Small 1933, p. 1381). The distribution was listed as 
the coastal plain and piedmont of Georgia and South Carolina. When 
Cronquist (1980) prepared the treatment of the Asteraceae for the 
Southeastern Flora, he included A. georgianus as a variety of A. 
patens. Jones (1983), in a Ph.D. dissertation on the Systematics of 
Aster Section Patentes (Vanderbilt University, TN), provided 
morphological (relating to form and structure of a plant or animal or 
its parts), cytological (cell-based), geographic distributional, and 
ecological evidence that supported consideration of this taxon as a 
distinct species.
    The genus Aster L. (sensu lato (in the broad sense)) contains 250-
300 species that occur in the northern Hemisphere of Eurasia and North 
America, with a few species occurring in South America (Nesom 1994). 
Recent evidence (derived from morphological and molecular characters as 
well as chromosome counts) supports earlier contentions that North 
American species are distinct from Eurasian and South American species, 
and a major revision of the genus is needed (e.g., Nesom 1994; Noyes 
and Rieseberg, 1999; Brouillet et al. 2001; Semple et al. 1996). 
According to these findings, the currently accepted nomenclature for 
this taxon is Symphyotrichum georgianum (Alexander) Nesom.

Habitat

    Symphyotrichum georgianum occupies woodlands and piedmont prairies. 
Soils vary from sand to heavy clay, with pH ranging from 4.4 to 6.8 at 
the sites sampled for a 1993 study on the species (Matthews 1993, p. 
20). The primary controlling factor appears to be the availability of 
light. The species is a good competitor with other early successional 
species, but tends to decline when shaded by woody species. Populations 
can persist for an undetermined length of time in the shade, but these 
rarely flower (Matthews 1993, p. 20) and reproduce only by rhizomes 
(horizontal underground stems that put out lateral shoots and 
adventitious roots at intervals).

Distribution

    Symphyotrichum georgianum is a relict species of post oak savanna/
prairie communities that existed across much of the southeastern United 
States prior to widespread fire suppression and extirpation of large 
native grazing animals (e.g., bison). The species appears to have been 
extirpated from Florida (Leon County), one of the five States in which 
it originally occurred. Symphyotrichum georgianum is presumed extant in 
5 counties in Alabama, 15 counties in Georgia, 9 counties in North 
Carolina, and 14 counties in South Carolina (Figure 1). The species has 
been documented at 283 site-specific locations that (due to the 
proximity of many sites) aggregate into 146 probable populations of the 
species. Of these 146 populations, 118 are presumed extant.

Life History

    A genetic study completed in 2013 supports the hypothesis that 
Symphyotrichum georgianum is a perennial outcrossing species due to the 
majority of its genetic variation being partitioned within populations 
(87.5%) with less (12.3%) partitioned among populations within States. 
The genetic relationships among populations roughly reflected 
geographic proximity, with populations grouping into three groups: 
Alabama, Georgia, and the Carolinas. This genetic study suggests no 
difference in genetic variation or seed fitness between large and small 
populations of S. georgianum (Gustafson 2013, pp. 4-5). A seed 
viability analysis study, done by the Atlanta Botanical Garden, showed 
that across the range of the species, the percentage of filled seed 
ranged from 77 percent to 99 percent with a trend for smaller 
populations to have higher percentages of filled seed. Seed germination 
ranged from 20 to 90 percent, with seeds from North Carolina 
populations having significantly lower germination percentages than 
seeds from other States (Cruse-Sanders 2013, p. 1).

Summary of Information Pertaining to the Five Factors

    Section 4 of the Act (16 U.S.C. 1533) and implementing regulations 
(50 CFR 424) set forth procedures for adding species to, removing 
species from, or reclassifying species on the Federal Lists of 
Endangered and Threatened Wildlife and Plants. Under section 4(a)(1) of 
the Act, a species may be determined to be endangered or threatened 
based on any of the following five factors:
    (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range;
    (B) Overutilization for commercial, recreational, scientific, or 
educational purposes;
    (C) Disease or predation;
    (D) The inadequacy of existing regulatory mechanisms; or
    (E) Other natural or manmade factors affecting its continued 
existence.
    In making this finding, information pertaining to the S. georgianum 
in relation to the five factors provided in section 4(a)(1) of the Act 
is discussed below. In considering what factors might constitute 
threats, we must look beyond the mere exposure of the species to the 
factor to determine whether the species responds to the factor in a way 
that causes actual impacts to the species. If there is exposure to a 
factor, but no response, or only a positive response, that factor is 
not a threat. If there is exposure and the species responds negatively, 
the factor may be a threat, and we then attempt to determine how 
significant a threat it is. If the threat is significant, it may drive 
or contribute to the risk of extinction of the species such that the 
species warrants listing as endangered or threatened as those terms are 
defined by the Act. This finding does not necessarily require empirical 
proof of a threat. The combination of exposure and some corroborating 
evidence of how the species is likely impacted could suffice. The mere 
identification of factors that could impact a species negatively is not 
sufficient to compel a finding that listing is appropriate; we require 
evidence that these factors are operative threats that act on the 
species to the point that the species meets the definition of an 
endangered or threatened species under the Act.
    In making our 12-month finding on the petition we considered and 
evaluated the best available scientific and commercial information.

Factor A. The Present or Threatened Destruction, Modification, or 
Curtailment of Its Habitat or Range

    The destruction and loss of habitat due to development can 
detrimentally affect small populations of many rare or locally endemic 
species, including Symphyotrichum georgianum. Habitat loss due to 
development has been considered a threat to the species in the States 
where it currently is found, and historically throughout its range (M. 
(Franklin) Buchanan, pers. comm. 2007; A. Schotz, pers. comm. 2007). 
Disturbance (e.g., fire, native grazers) is a part of this species' 
habitat requirements. The historical sources of this disturbance have 
been virtually eliminated from S. georgianum's range, except where 
road, railroad, and rights-of-way (ROW) maintenance is mimicking the 
missing natural disturbances. The habitat of some existing populations 
continues to be subject to destruction, modification, or curtailment 
due to planned residential subdivision development, highway expansion/
improvement projects, and woody succession due to fire suppression.
Conservation Efforts To Reduce Habitat Destruction, Modification, or 
Curtailment of Its Range
    Conservation partners have been working to manage Symphyotrichum 
georgianum, and improvements are continually being made in population 
size and vigor. A few examples of work by our partners to conserve this 
plant are highlighted below.

Georgia Department of Natural Resources

    Oaky Woods Wildlife Management Area in Georgia has used prescribed 
fires to help manage for this species. In October 2006, Symphyotrichum 
georgianum (one patch with five flowering-stems) was discovered on the 
largest prairie remnant in Oaky Woods. Regular winter and early growing 
season burns every 1 to 3 years on the S. georgianum prairie since 2007 
greatly enhanced the prairie. By 2012, the small patch had increased to 
more than 80 flowering stems in a 30 meter (m) by 10 m area, and 
several new patches have been found on other parts of the prairie 
habitat (T. Patrick, pers. comm. 2013).

U.S. Forest Service (USFS)

    The USFS has been thinning woody vegetation, conducting prescribed 
burns, and treating for nonnative invasive species to manage for 
Symphyotrichum georgianum on national forest land throughout the 
species' range. For example, management has aided many populations on 
the Chattahoochee National Forest in Georgia. As of 2013, nine 
populations, totaling roughly 5,000 S. georgianum stems, grow on the 
Chattahoochee National Forest. The Chattahoochee National Forest is 
also working with partners on propagation and out-planting (J. Baggs, 
pers. comm. 2013). The Talladega National Forest contains Alabama's 
largest population (approximately 4,000 individuals). In 2008, the 
Talladega National Forest thinned longleaf pine (Pinus palustris) 
stands to savannah conditions specifically to aid the S. georgianum 
population. The Talladega National Forest is partnering with Auburn 
University to grow and plant approximately 2,000 S. georgianum 
seedlings (G. Shurette, pers. comm. 2013). The Uwharrie National Forest 
in North Carolina reduced the basal area (average amount of an area 
occupied by tree stems) of an oak-hickory forest adjacent to a S. 
georgianum population from 100 square feet (ft\2\) to less than 40 
ft\2\ in 2002. This area was burned in 2003 with the fireline 
constructed next to the original S. georgianum population of 60 stems. 
This population expanded into the fireline by 2004, and stem counts in 
2010 and 2011 indicated a 25-fold increase from 1998 counts (G. 
Kauffman, pers. comm. 2013). Sumter National Forest is using 
propagation, out-planting, prescribed-fire, and woody vegetation 
thinning to increase S. georgianum population size (R. Mackie,

[[Page 56044]]

pers. comm. 2013). More than 7,000 individuals of S. georgianum from 13 
populations grow on the Sumter National Forest in South Carolina.

National Park Service

    The Chattahoochee River National Recreation Area in Georgia 
annually monitors the populations that grow in the park. In 
coordination with the Georgia Department of Transportation, plants were 
rescued from a road-widening site within the park in 2012 and planted 
near a parking lot which is maintained via weed-trimming in winter 
months. This site now has 256 stems showing good viability (Read and 
Pierson 2012).

State Departments of Transportation

    In Georgia, North Carolina and South Carolina, populations have 
been relocated in advance of road improvement activities that would 
have destroyed or modified S. georgianum habitat.
Summary of Factor A
    Since the Service added Symphyotrichum georgianum to the candidate 
list in 1999, more than 50 additional populations of the species have 
been discovered. There are currently 118 known populations of the 
species occurring in 4 States. While an unknown number of S. georgianum 
populations may be subject to future habitat loss due to development, a 
minimum of 55 populations occur on lands managed for conservation. 
These populations are not subject to development and are being managed 
to maintain and enhance S. georgianum.
    Therefore, we conclude, based on the best scientific and commercial 
information available, that the present or threatened destruction, 
modification, or curtailment of its habitat or range is not considered 
a threat to this species, nor is it likely to become a threat in the 
foreseeable future.

Candidate Conservation Agreement (CCA)

    The Service has also worked with partners to create a CCA to 
establish a formal framework for public and private landowners to 
continue to cooperate on actions (like those described above) that 
conserve, manage, and improve Symphyotrichum georgianum populations 
range-wide. Signed by multiple landowners in May 2014, the CCA is 
voluntary and flexible in nature and aims to continue to reduce habitat 
destruction, modification, or curtailment of S. georgianum range 
through management techniques designed to mimic natural disturbance by 
natural or prescribed fire or direct management such as mowing or 
silvicultural techniques.

Factor B. Overutilization for Commercial, Recreational, Scientific, or 
Educational Purposes

    This species is not currently known to be a significant component 
of the commercial trade, and the Service is not aware of any 
utilization of Symphyotrichum georgianum for recreational, scientific, 
or educational purposes. Furthermore, we found no information 
indicating that overutilization has led to the loss of populations or a 
significant reduction in numbers of individuals of this species. 
Therefore, we conclude based on the best scientific and commercial 
information available that overutilization for commercial, 
recreational, scientific, or educational purposes does not currently 
pose a threat to S. georgianum, nor is it likely to become a threat in 
the foreseeable future.

Factor C. Disease or Predation

    In 2010 and 2011, researchers from the North Carolina Botanical 
Garden, USFS and the Service found larvae (not yet identified) feeding 
on seeds inside the heads of Symphyotrichum georgianum at all sites 
visited in North Carolina. This activity was also observed in other 
Asteraceae blooming in the fall during the same study period. Percent 
of infested heads varied by site and ranged from 10 percent to 40 
percent of S. georgianum seed heads present. Seeds in infested heads 
seemed to have low to no viability.
    There was evidence of deer browse and reduced seed set at one North 
Carolina site in 2011 (M. Kunz, pers. comm. 2012). The North Carolina 
Department of Transportation (NCDOT) found that one population they 
helped to conserve was heavily impacted by deer browse, prompting them 
to place deer fencing around transplants in a conservation area (Herman 
and Frazer 2012, p. 3). Many of Georgia's populations are also impacted 
by deer browse (M. Moffet and T. Patrick, pers. comm. 2013).
Conservation Efforts to Reduce Disease or Predation
    The NCDOT placed deer fencing around one population of S. 
georgianum that they helped conserve.
    Although there is evidence showing this species has been impacted 
by disease and predation, we found no information indicating that 
disease or predation on Symphyotrichum georgianum has led to the loss 
of populations or a significant reduction in numbers of individuals for 
this species. Therefore, we conclude, based on the best scientific and 
commercial information available, that disease or predation does not 
currently pose a threat to the species, nor is it likely to become a 
threat in the foreseeable future.

Factor D. The Inadequacy of Existing Regulatory Mechanisms

    Section 4(b)(1)(A) of the Act requires the Service to take into 
account ``those efforts, if any, being made by any state or foreign 
nation, to protect such species . . .'' In relation to Factor D under 
the Act, we interpret this language to require the Service to consider 
relevant Federal, State and tribal laws, plans, regulations and other 
such mechanisms that may minimize any of the threats we describe in 
threat analyses under the other four factors or otherwise enhance 
conservation of the species. Having evaluated the significance of the 
threat as mitigated by any such conservation efforts, we analyze under 
Factor D the extent to which regulatory mechanisms are inadequate to 
address the specific threats to the species. Regulatory mechanisms, if 
they exist, may reduce or eliminate the impacts from one or more 
identified threats. We give strongest weight to statutes and their 
implementing regulations and to management direction that stems from 
those laws and regulations. An example would be State governmental 
actions enforced under a State statute or constitution or Federal 
action under statute.
State Regulations
    The North Carolina Plant Conservation and Protection Act (NC State 
Code Article 19B, Sec.  106-202.12) provides limited protection from 
unauthorized collection and trade of plants listed under that statute. 
However, this statute was not designed to protect the species or its 
habitat from destruction in conjunction with development projects or 
otherwise legal activities. Plant species are afforded some protection 
in South Carolina; they are protected from disturbance where they occur 
on properties owned by the State and specifically managed as South 
Carolina Heritage Preserves (SC State Code of Regulations Part 123 
Sec.  200-204). Portions of two South Carolina populations occur on 
State park land and are afforded some protection by this State statute. 
Collection of S. georgianum on public lands without a permit is 
prohibited in Georgia under the Georgia Wildflower Preservation Act of 
1973. However, no such provisions

[[Page 56045]]

are afforded to plants found on privately owned lands in the State. The 
species does not receive any specific legal protections from State laws 
or regulations in Alabama.
Federal Regulations
    Thirty-eight extant populations of Symphyotrichum georgianum occur 
on Federal lands (USFS National Forest lands, including the 
Chattahoochee-Oconee, Sumter, Talladega, and Uwharrie National Forests; 
National Park Service (NPS) lands, including the Chattahoochee River 
National Recreation Area and Kings Mountain National Military Park; the 
Cahaba River National Wildlife Refuge; and land owned by the U.S. Army 
Corps of Engineers).
    The USFS has to maintain viability of this plant on each planning 
unit where it occurs because Symphyotrichum georgianum is a USFS region 
8 sensitive species (USFS Handbook 2670 written in 1991, updated by the 
regional forester in 2001 with S. georgianum added). The USFS considers 
the effects of their actions on the viability of sensitive species 
through the National Environmental Policy Act process. As defined by 
USFS policy, actions should not result in loss of species' viability or 
create significant trends toward the need for Federal listing.
    National Park Service policies (NPS 2006) state that ``The National 
Park Service will inventory, monitor, and manage state and locally 
listed species in a manner similar to its treatment of federally listed 
species to the greatest extent possible. In addition, the NPS will 
inventory other native species that are of special management concern 
to parks (such as rare, declining, sensitive, or unique species and 
their habitats) and will manage them to maintain their natural 
distribution and abundance.''
    Management practices being implemented by the USFS and NPS through 
their policies help abate the threat of habitat destruction, 
modification, or curtailment to 36 Symphyotrichum georgianum 
populations on Federal lands.
Tribal Regulations
    We are not aware of any populations of Symphyotrichum georgianum 
that occur on tribal lands; therefore, there are no tribal regulations 
that would apply.
    Existing regulatory mechanisms are working as designed to reduce or 
minimize impacts to Symphyotrichum georgianum. Therefore, we conclude, 
based on the best scientific and commercial information available, that 
the inadequacy of existing regulatory mechanisms does not currently 
pose a threat to S. georgianum, nor is it likely to become a threat in 
the foreseeable future.

Factor E. Other Natural or Manmade Factors Affecting Its Continued 
Existence

    Due to the elimination of historical sources of disturbance that 
helped maintain suitable habitat conditions for the species, most of 
the known populations of Symphyotrichum georgianum are now found 
adjacent to roads, railroads, utility ROW, and other openings where 
land management mimics natural disturbance regimes. However, at these 
locations S. georgianum also is inherently vulnerable to accidental 
destruction from herbicide application, road shoulder grading, and 
other maintenance activities. More utility companies and railroads are 
shifting to herbicide spraying instead of mowing for longer lasting 
control of vegetation growth. Repeated mowing of S. georgianum 
populations during the height of the growing season can reduce 
population vigor, and may eventually kill plants, but these effects 
take longer to manifest than direct application of herbicides during 
the growing season.
    Several sites are impacted by the encroachment of invasive exotic 
plants. Examples of these invasive exotic plants include autumn olive 
(Elaeagnus umbellata), Japanese honeysuckle (Lonicera japonica), 
bicolor lespedeza (Lespedeza bicolor), sericea (Lespedeza cuneata), 
kudzu (Pueraria lobata), Johnson grass (Sorghum halepense) and Bahia 
grass (Paspalum notatum). At this time, however, we have no information 
on the nature or extent of the impacts of invasive plants.
Conservation Efforts To Reduce Other Natural or Manmade Factors 
Affecting Its Continued Existence
    The NCDOT signed a Memorandum of Understanding (MOU) with the North 
Carolina Department of Environment and Natural Resources (NCDENR) in 
1990. Under the MOU, NCDOT agrees to protect populations of North 
Carolina rare species that occur on NCDOT ROW. In addition to other 
management actions, under this agreement, NCDOT does not mow in the 
height of the growing season, and they do not use herbicides near known 
Symphyotrichum georgianum populations.
    Since Symphyotrichum georgianum was added to the candidate species 
list in 1999, many threats have been reduced or abated, including 
potential threats from herbicide application, and other road and 
utility ROW maintenance activities.
    Therefore, we conclude, based on the best scientific and commercial 
information available, that the threat of other natural or manmade 
factors has been reduced considerably, and these factors do not 
currently pose a threat to Symphyotrichum georgianum, nor are they 
likely to in the foreseeable future.
    As described under Factor A, the CCA formalizes management 
activities that partners have already been implementing to protect and 
enhance S. georgianum and its habitat.

Cumulative Effects From Factors A through E

    None of the cumulative impacts will rise to the level that warrants 
listing under the Act. The current and threatened destruction, 
modification, and curtailment of the habitat and range of the species 
(Factor A) are a concern for the species in the States where it 
currently is found. Residential subdivision development, highway 
expansion/improvement projects, and woody succession due to fire 
suppression are all stressors to habitat. However, these stressors are 
abated in a large percentage (45 percent) of known populations due to 
management practices currently being undertaken by USFS, NPS, and 
multiple State agencies. Existing State regulatory mechanisms were not 
designed to protect the species or its habitat from destruction in 
conjunction with development projects or otherwise legal activities, 
which is a concern. However, the Federal regulations implemented by the 
USFS and NPS help to protect 36 populations. As described in Factor E, 
management (mowing and herbicide applications) of roadside and utility 
ROW, where the majority of the known remaining populations occur, can 
directly kill the plants. This stressor has been abated in NCDOT ROW 
due to their MOU with NCDENR.
    The CCA simply formalized these ongoing management practices. These 
management actions will continue to be implemented throughout the 
species' range.

Finding

    As required by the Act, we considered the five factors in assessing 
whether Symphyotrichum georgianum is endangered or threatened 
throughout all of its range. We examined the best scientific and 
commercial information available regarding the past, present, and 
future threats faced by S. georgianum. We reviewed the petition, 
information available in our files, and other available published and

[[Page 56046]]

unpublished information, and we consulted with recognized S. georgianum 
experts and other Federal and State agencies.
    The species is relatively widely distributed across 4 States with 
an estimated 118 existing populations. Recent information indicates the 
species is more abundant now than when we initially identified it as a 
candidate for listing in 1999 when approximately 60 populations were 
known. Due to this increase in known abundance of Symphyotrichum 
georgianum, the magnitude of threats has been reduced, as noted 
previously in our downgrading of the species' listing priority number 
in the Service's 2007 CNOR (72 FR 69034).
    Based on our review of the best available scientific and commercial 
information pertaining to the five factors, we find that the threats 
are not of sufficient imminence, intensity, or magnitude to indicate 
that the Symphyotrichum georgianum is in danger of extinction 
(endangered), or likely to become endangered within the foreseeable 
future (threatened), throughout all of its range.

Distinct Vertebrate Population Segment (DPS)

    Symphyotrichum georgianum is not a vertebrate, and therefore the 
Service's DPS policy does not apply.

Significant Portion of the Range

    Under the Act and our implementing regulations, a species may 
warrant listing if it is an endangered or a threatened species 
throughout all or a significant portion of its range. The Act defines 
``endangered species'' as any species which is ``in danger of 
extinction throughout all or a significant portion of its range,'' and 
``threatened species'' as any species which is ``likely to become an 
endangered species within the foreseeable future throughout all or a 
significant portion of its range.'' The term ``species'' includes ``any 
subspecies of fish or wildlife or plants, and any distinct population 
segment [DPS] of any species of vertebrate fish or wildlife which 
interbreeds when mature.'' We published a final policy interpretating 
the phrase ``Significant Portion of its Range'' (SPR) (79 FR 37578). 
The final policy states that (1) if a species is found to be an 
endangered or a threatened species throughout a significant portion of 
its range, the entire species is listed as an endangered or a 
threatened species, respectively, and the Act's protections apply to 
all individuals of the species wherever found; (2) a portion of the 
range of a species is ``significant'' if the species is not currently 
an endangered or a threatened species throughout all of its range, but 
the portion's contribution to the viability of the species is so 
important that, without the members in that portion, the species would 
be in danger of extinction, or likely to become so in the foreseeable 
future, throughout all of its range; (3) the range of a species is 
considered to be the general geographical area within which that 
species can be found at the time FWS or NMFS makes any particular 
status determination; and (4) if a vertebrate species is an endangered 
or a threatened species throughout an SPR, and the population in that 
significant portion is a valid DPS, we will list the DPS rather than 
the entire taxonomic species or subspecies.
    The SPR policy is applied to all status determinations, including 
analyses for the purposes of making listing, delisting, and 
reclassification determinations. The procedure for analyzing whether 
any portion is an SPR is similar, regardless of the type of status 
determination we are making. The first step in our analysis of the 
status of a species is to determine its status throughout all of its 
range. If we determine that the species is in danger of extinction, or 
likely to become so in the foreseeable future, throughout all of its 
range, we list the species as an endangered (or threatened) species and 
no SPR analysis will be required. If the species is neither an 
endangered nor a threatened species throughout all of its range, we 
determine whether the species is an endangered or a threatened species 
throughout a significant portion of its range. If it is, we list the 
species as an endangered or a threatened species, respectively; if it 
is not, we conclude that listing the species is not warranted.
    When we conduct an SPR analysis, we first identify any portions of 
the species' range that warrant further consideration. The range of a 
species can theoretically be divided into portions in an infinite 
number of ways. However, there is no purpose to analyzing portions of 
the range that are not reasonably likely to be significant and either 
an endangered or a threatened species. To identify only those portions 
that warrant further consideration, we determine whether there is 
substantial information indicating that (1) the portions may be 
significant and (2) the species may be in danger of extinction in those 
portions or likely to become so within the foreseeable future. We 
emphasize that answering these questions in the affirmative is not a 
determination that the species is an endangered or a threatened species 
throughout a significant portion of its range--rather, it is a step in 
determining whether a more detailed analysis of the issue is required. 
In practice, a key part of this analysis is whether the threats are 
geographically concentrated in some way. If the threats to the species 
are affecting it uniformly throughout its range, no portion is likely 
to warrant further consideration. Moreover, if any concentration of 
threats apply only to portions of the range that clearly do not meet 
the biologically based definition of ``significant'' (i.e., the loss of 
that portion clearly would not be expected to increase the 
vulnerability to extinction of the entire species), those portions will 
not warrant further consideration.
    If we identify any portions that may be both (1) significant and 
(2) endangered or threatened, we engage in a more detailed analysis to 
determine whether these standards are indeed met. The identification of 
an SPR does not create a presumption, prejudgment, or other 
determination as to whether the species in that identified SPR is an 
endangered or a threatened species. We must go through a separate 
analysis to determine whether the species is an endangered or a 
threatened species in the SPR. To determine whether a species is an 
endangered or a threatened species throughout an SPR, we will use the 
same standards and methodology that we use to determine if a species is 
an endangered or a threatened species throughout its range.
    Depending on the biology of the species, its range, and the threats 
it faces, it may be more efficient to address the ``significant'' 
question first, or the status question first. Thus, if we determine 
that a portion of the range is not ``significant,'' we do not need to 
determine whether the species is an endangered or a threatened species 
there; if we determine that the species is not an endangered or a 
threatened species in a portion of its range, we do not need to 
determine if that portion is ``significant.''
    We evaluated the current range of Symphyotrichum georgianum to 
determine if there is any apparent geographic concentration of 
potential threats for this species. We examined potential threats and 
found no concentration of threats that suggests that S. georgianum may 
be in danger of extinction in a portion of its range. We found no 
portions of the range where potential threats are significantly 
concentrated or substantially greater than in other portions of its 
range. Therefore, we find that the factors affecting S. georgianum are 
essentially uniform throughout its range, indicating no portion of the 
range warrants further

consideration of possible endangered or threatened status under the 
Act.
    Our review of the best available scientific and commercial 
information indicates that the Symphyotrichum georgianum is not in 
danger of extinction (endangered) nor likely to become endangered 
within the foreseeable future (a threatened species), throughout all or 
a significant portion of its range. Therefore, we find that listing 
Symphyotrichum georgianum as an endangered or threatened species under 
the Act is not warranted at this time.
    We request that you submit any new information concerning the 
status of, or threats to, Symphyotrichum georgianum to our Asheville 
Ecological Services Field Office (see ADDRESSES) whenever it becomes 
available. New information will help us monitor S. georgianum and 
encourage its conservation. If an emergency situation develops for S. 
georgianum, we will act to provide immediate protection.
