36 CFR Part 7

RIN 1024-AD10


Special Regulations, Areas of the National Park System; Saguaro 
National Park, Designated Bicycle Routes

AGENCY: National Park Service, Interior.

ACTION: Final rule.

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

SUMMARY: The National Park Service (NPS) is designating a trail where 
bicycles may be used off road in Saguaro National Park. This rule is 
necessary because the NPS regulations for bicycle use off park roads in 
units of the National Park System require that a special regulation be 
promulgated in order to allow use on trails outside of developed park 
areas.

DATES: The rule becomes effective September 19, 2003.

ADDRESSES: Superintendent, Saguaro National Park, 3693 South Old 
Spanish Trail, Tucson, AZ 85730-5601 e-mail: [email protected]. Fax: (520) 733-5183.

SUPPLEMENTARY INFORMATION:

Description of Saguaro National Park

    Saguaro National Park is an important national resource visited by 
approximately 755,618 people annually. The gross area acreage is 
91,445.96 (Federal: 87,156.17; Nonfederal: 4,289.79) of which 71,400 
acres are designated wilderness. Giant saguaro cacti, unique to the 
Sonoran Desert, sometimes reach a height of 50 feet in this cactus 
forest, which covers the valley floor and the slopes of the Rincon and 
Tucson Mountains. The Cactus Forest Trail is a multi-use trail (5.3 
miles long) that originates at the northern boundary of the park and 
eventually bisects the Cactus Forest Loop Drive. The segment of the 
Cactus Forest Trail within the loop drive is 2.5 miles long. Cactus 
Forest Loop Drive, an 8 mile paved loop road located in the western 
portion of the Rincon Mountain District, originates from the main 
entrance and visitor center and is the only paved road in the east 
district of the park. The Cactus Forest Trail is designed along the 
natural topography and vegetation of the area and meanders through a 
relatively even elevation with rolling hills and gentle peaks. The 
trail is lined with a variety and abundance of desert trees and shrubs.

Legislation and Purposes of Saguaro National Park

    Saguaro National Park was initially reserved as a national monument 
on March 1, 1933 (Proclamation No. 2032, 47 Stat. 2557), and 
transferred from the Forest Service, U.S. Dept. of Agriculture, to the 
National Park Service on August 10, 1933. This area was of outstanding 
scientific interest because of the exceptional growth of various 
species of cacti, including the so-called giant saguaro cactus. 
Proclamation 3439 (November 16, 1961), enlarged the boundaries of the 
Saguaro National Monument to include certain lands within the Tucson 
Mountains containing a remarkable display of relatively undisturbed 
lower Sonoran desert vegetation, including a spectacular saguaro stand. 
Public Law 94-567(October 1976) designated parts of Saguaro National 
Monument as a wilderness area, known as the Saguaro Wilderness.
    On June 19, 1991 Congress passed the ``Saguaro National Monument 
Expansion Act of 1991'' to authorize the addition of approximately 
3,540 acres to the Rincon unit of Saguaro National Monument in order to 
protect, preserve, and interpret the monument's resources, and to 
provide for education and benefit to the public. Under the Saguaro 
National Park Establishment Act of 1994, Saguaro National Monument was 
given full recognition and statutory protection and renamed a National 
Park. See 16 U.S.C. 410ZZ.

Management Plans

    Saguaro National Park General Management Plan (GMP) was completed 
in 1988. The GMP envisions the Rincon Mountain District as a main 
attraction for the first-time visitors, with the focus on the Saguaro 
forest and the lower Sonoran desert. Suggested frontcountry 
recreational uses include ``* * * biking, jogging, picnicking, sunset 
watching, and horseback riding'', while the ``* * * backcountry 
wilderness would continue to be used primarily by hikers and horseback 
riders.'' In the 1988 plan, the Cactus Forest trail is located in the

[[Page 50074]]

frontcountry natural zone with a historic zone overlay. The management 
emphasis of the natural zone is the conservation of natural resources 
and processes. The plan states that ``In certain locations, uses are 
allowed that do not adversely affect these resources and processes.''
    The park's trail plan for the Cactus Forest section of the Rincon 
Mountain District was completed in 1991. In addition to hiking and 
equestrian use, the plan proposed that the Cactus Forest Trail inside 
the Cactus Forest Loop Road be open to bicycle use for a one-year trial 
period. The plan also proposed the monitoring program designed to 
evaluate the environmental and social impacts of mountain bike use on 
the trail. The park adopted the plan's proposal and the trial period 
was extended for more than 10 years. The monitoring plan results 
indicated, overall, that any adverse impacts associated with bicycle 
use was negligible.
    Starting in 1991, bicyclists, pedestrians, and equestrians were 
allowed to use the portion of the Cactus Forest Trail within the paved 
loop drive area. Recently, it was brought to the Park's attention that 
National Park Service regulations appear to require promulgation of a 
special regulation to permit bicycle use along the 2.5-mile section of 
the Cactus Forest Trail. In reviewing the actions leading to the 
opening of this trail for mountain bike use over 10 years ago, the Park 
discovered that the requirements in the regulation governing bicycle 
use had not been followed. While the trail is located in the 
frontcountry as identified in the GMP, the area is designated a natural 
zone. Under the servicewide regulations, because the trail is not in a 
developed area or special use zone the park is required by 36 CFR 
4.30(b) to adopt a special regulation to designate a route for bicycle 
use. In part the regulations state that:

    Routes may only be designated for bicycle use based on a written 
determination that such use is consistent with the protection of a 
park area's natural, scenic and aesthetic values, safety 
considerations and management objectives and will not disturb 
wildlife or park resources. Except for routes designated in 
developed areas and special use zones, routes designated for bicycle 
use shall be promulgated as special regulations. (36 CFR 4.30)

    Based on the criteria in the regulations, and the fact that the 
trail was not identified as being in a developed zone in the GMP in 
1988, the Park determined that it did not then have the authority to 
allow such use on the trail. On April 15, 2002, the park closed the 
Cactus Forest Trail to bicycle use and initiated an Environmental 
Assessment and the special regulation process. In addition, the park 
will be addressing the bicycle use issue in a comprehensive way through 
the new GMP process that began in September 2002. The new GMP is 
scheduled to be complete in approximately 2-3 years. Apart from this 
Final rule, in the meantime, bicycles are allowed to use paved and 
unpaved roads in the park pursuant to 36 CFR 4.30(a).

History of Bicycle Use

    In the early 1990's the NPS was in the process of preparing a 
trails management plan for the Cactus Forest section of the park. 
During the planning process, public scoping revealed that some members 
of the local community and the visiting public were interested in 
mountain bike trails in the park. Based on this information, the NPS 
analyzed the appropriateness of establishing mountain bike trails. As 
noted above, the park opened that portion of the trail inside the 
Cactus Forest Loop Road to mountain bike use for a one-year trial 
period. The park monitored the trail for resource and social impacts by 
implementing a monitoring plan that included sixteen photo-points along 
the trail. Park staff monitored these locations on a monthly basis.
    The park recorded approximately 1,200 bicyclists, or nearly 50% of 
all trail users, on the trail between May 1, 1991 and June 30, 1992. 
There were no major incidents or accidents during the trial period. At 
the end of the one-year period, the park concluded that monitoring data 
revealed little measurable resource impact caused by bicycle use and 
the decision was made to keep the Cactus Forest Trail inside the loop 
road open to bicycle use. The park continued to monitor the trail for 
resource damage at the designated monitoring points, performed patrols, 
and engaged in informal contact with visitors using the trail. 
Continued use of that trail by bicyclists had been authorized by the 
Superintendent's Compendium since that time. Until bicycle use was 
prohibited in April 2002, the trail continued to be a popular trail for 
mountain biking. Much of the trail follows an old two-track road that 
was allowed to revegetate and become a trail. About half the use of the 
trail is by hikers and equestrians.

Impacts

    Soils: Reinstating mountain bike use would likely result in added 
visitation on the trail. This type of use would impact soils 
differently than hiking and equestrian use. Some monitoring points show 
that soil erosion and loss has been exacerbated by the ``cupping'' of 
the cross-section of the trail that is caused by repeated use in the 
center of the trail. At times, multiple uses occurring on the trail 
have resulted in beneficial impacts by redistributing soils across the 
trail. Soils may be distributed from the center of the trail to the 
sides by cyclists, and then loosened and redistributed in the center of 
the trail by horses and hikers. Park staff would continue to maintain 
the trail depending on available staffing and funding levels. With 
proper trail repair and maintenance, the overall effect of added 
visitation on soils would be of minor intensity.
    Vegetation: Mountain bike use would contribute to a greater amount 
of disturbance of vegetation from riders dismounting from their bikes 
onto the side of the trail to yield to another trail user or to push 
their bike uphill. Vegetation that is affected is typically located in 
steeper slopes or where the trail curves and is lost through repeated 
trampling. Impacts from the added use would be of minor intensity. 
Trail repair and rehabilitation may offset some of the impacts 
associated with trailside vegetation loss. Trailside re-vegetation 
efforts could help to restore the natural scene, as well as contribute 
to a more defined trail path.
    Wildlife: Wildlife would be frightened or displaced by the presence 
of visitors. However, given the higher speeds that mountain bicycles 
may reach on the trail, there may be a greater tendency for cyclists to 
encounter and frighten wildlife. There may also be a greater tendency 
for mountain bikers to run over smaller vertebrates such as snakes on 
the trail. These factors, along with an anticipated increase in the 
amount of use on the trail are expected to result in more individual 
wildlife species being frightened and displaced from the immediate 
area. Overall, the impacts of this use on wildlife would be of minor 
intensity.
    Archeological resources: Reinstating bicycle use on the Cactus 
Forest Trail would not have any additional impacts on archeological 
resources or historic structures. As with any increase in visitation, 
however, there is a greater possibility that cultural resources could 
be discovered and/or damaged. Bicycle use off the trail would not be 
permitted and it is anticipated that visitors would remain on the 
trail; therefore, impacts to archeological resources and historic 
structures would be negligible.
    Visitor conflicts: Bicyclists would view the opportunity for an 
off-road experience in the park as beneficial. However, some hikers and 
equestrians

[[Page 50075]]

would feel as though their ability to experience park resources along 
the trail is diminished if they see mountain bike use as incompatible 
with their desired experience. Some hikers and equestrians may choose 
to use the trail less or avoid the trail completely. However, the 
multi-use orientation of the trail would be likely to have no more than 
minor impacts on a hiker or equestrian's ability to experience the 
park. This is because a number and variety of other trails in the 
Cactus Forest area are open to hiking and equestrian use only.
    Visitor safety: There would be a greater potential for visitor 
accidents under this Final rule in comparison to no bicycle use. 
Mountain bikes traveling at higher speeds could inadvertently collide 
with other recreationists, regardless of their mode of travel. Horses 
may be frightened by bicyclists and their response may result in a 
number of unsafe situations. Given the past record of incidents on this 
trail, however, reinstating mountain bike use would not be considered 
an unsafe use if recreationists continued to abide by the recommended 
trail etiquette/rules. Overall impacts to visitor safety would be 
negligible to minor in intensity.
    Threatened species: According to the U.S. Fish and Wildlife 
Service's October 2001 list of listed, proposed and candidate species 
for the area, there are seven species of concern, including four 
federally listed species (Mexican spotted owl, cactus ferruginous 
pygmy-owl, lesser long-nosed bat, Gila topminnow), one delisted species 
(American peregrine falcon), and two species proposed for listing 
(Chiricahua leopard frog, Goodding Onion) that are known to or might 
occur in the Rincon Mountain District where the Cactus Forest Trail is 
located.
    The Goodding onion has not been recorded in the Rincon Mountains. 
The Cactus Forest Trail is in the same watershed as a drainage that 
could potentially be used to restock Gila topminnow. However, the 
Cactus Forest Trail is well below and disjunct from that drainage, and 
activities on the Cactus Forest Trail would have no impact on that 
drainage or affect its potential to reintroduce this fish. Despite 
surveys throughout the Rincon Mountains by Saguaro and other NPS 
biological staff, Chiricahua leopard frogs have never been recorded in 
Saguaro National Park. Furthermore, the proposed action will not affect 
potential habitat for this frog, which requires surface water above 
3,000' elevation.
    The Cactus Forest Trail is located over a mile from the known 
Lesser long-nosed bat roost, and neither the trail, nor any of the 
activities proposed to occur on it, would be expected to disturb bats 
(which forage after dark), or saguaros or agaves, upon which the bats 
forage. Cactus ferruginous pygmy-owls (cfpo) have not been confirmed to 
occur in the Park since intensive surveys began in 1995; however, they 
may inhabit, and have the potential to breed, in the low (<4000') 
elevations of the Rincon Mountain District of the Park. Within the last 
20 years, one possible detection of this species occurred within a 
half-mile of the Cactus Forest Trail. Based on the descriptions of 
recently occupied territories, it does not appear that human presence, 
particularly established presence, is a deterrent to owl occupancy of a 
site.
    American peregrine falcons are known to occur in the Rincon 
Mountain District, and may forage and perch around the project area in 
the non-breeding season. Peregrines may be affected by and try to avoid 
human activities on the Cactus Forest Trail; however, hiking, riding or 
biking on an established trail would be expected to have negligible to 
minor impacts on these birds. Five Mexican spotted owl protected 
activity centers lie within the Rincon Mountain District above 7000' 
elevation. Designated critical habitat for the owl does not include the 
Cactus Forest Trail, nor is the project area suitable habitat for the 
owls.
    The biological evaluation of these threatened and endangered 
species as part of the proposed action found that there would be no 
effect on the Mexican spotted owl, the Lesser long-nosed bat, or the 
Gila topminnow. One confirmed detection of the Cactus ferruginous pygmy 
owl within the park occurred in 1995 and two possible detections have 
occurred in the past two years, one of which was within half a mile of 
the Cactus Forest Trail. Fast moving bicycles, with their hard frames 
and spokes, might pose a slightly higher collision risk for the Cactus 
ferruginous pygmy owl than hikers or horses would, therefore, the 
proposed action may affect but is not likely to adversely affect Cactus 
ferruginous pygmy-owls or their habitat.
    The U.S. Fish and Wildlife Service concurred with the determination 
of effect stated in the biological evaluation in a letter dated January 
16, 2003.

Authorizing Bicycle Use

    The final rule opens the approximately 2.5 mile section of the 
Cactus Forest Trail located within the Cactus Forest Drive loop to 
mountain biking on a permanent basis. The park will continue to monitor 
and mitigate the environmental impacts of mountain bike use through the 
use of volunteer organizations and local interest groups to ensure that 
the trail is maintained in good condition and issues of concern are 
immediately brought to the attention of the park management staff.

Public Comments

    Saguaro National Park conducted initial internal scoping with 
appropriate park staff. Internal scoping was conducted by an 
interdisciplinary team of Saguaro National Park, and planning 
professionals of the National Park Service, Intermountain Support 
Office in Denver. Teams members conducted a field trip on July 11, 2002 
to discuss purpose and need; important resource topics; past, present, 
and possible mitigation of the proposed action. Affiliated Native 
American tribes were contacted by letter dated July 12, 2002 to solicit 
any interests or concerns with the proposed action. External scoping 
was through a public scoping letter dated August 2002 and mailed to 
interested and affected parties. A press release was mailed to local 
newspapers.
    The environmental assessment was released for public review and 
comment during a 30-day period ending November 20, 2002. The proposed 
rule was published on March 7, 2003 (68 FR 11019) and was open for 
public comment for 60 days. A total of 31 comments were received. 
Twenty-four of those writing in fully support the proposal to reopen 
the route to bike use. Four commentors did not support continued bike 
use on that trail. Other specific, substantive comments are summarized 
below.
    1. Comment: One commentor suggested that additional routes be 
opened for mountain bike use.
    Response: The scope of this project is limited to the Cactus Forest 
Trail inside the Cactus Forest Loop Drive and, accordingly, the rule 
only considers whether this specific trail can be reopened based on the 
analysis contained in the supporting environmental assessment. 
Additional trails may be considered during the General Management Plan 
process beginning at the park.
    2. Comment: Several commentors felt that horses create more impact 
than bicycles on that trail and therefore bicycles should not be 
excluded while horses continue to be allowed.
    Response: All recreational uses (hiking, equestrian, bicycling) 
contribute to impacts to the trail. The environmental assessment 
analyzed impacts resulting from all user groups before selecting an 
alternative. Additionally, under 36 CFR 4.30, bicycles may only be 
allowed upon

[[Page 50076]]

promulgation of a special regulation. Under 36 CFR 2.16, Horses and 
pack animals, the Superintendent is only required to designate areas 
where a horse may be used, not promulgate a special regulation.
    3. Comment: Two commentors felt that other trails in the park would 
be more suitable for mountain bike use instead of this trail.
    Response: The scope of the project was limited to the Cactus Forest 
Trail inside the Cactus Forest Loop Road. As the General Management 
Plan proceeds, other areas may be considered for bike use as well.
    4. Comment: Many commentors did not feel that bicycles had caused 
unacceptable impacts to the Cactus Forest Loop Trail in the past and 
therefore should not be prohibited from using that trail now.
    Response: The NPS would agree that based on previous monitoring and 
information compiled during the environmental assessment, bicycles have 
not created unacceptable impacts to the trail and continued use is 
appropriate.
    5. Comment: Having the trail open to mountain bike use provides 
economic benefit to the community as well as health benefits to users 
and should continue to be allowed.
    Response: Although the NPS believes that economic benefits 
resulting from reopening the trail to mountain bike use would be 
negligible, the NPS would generally agree that continued bike use will 
provide positive recreational benefits to the community and continued 
bike use is appropriate.
    6. Comment: One commentor suggested the NPS charge a small fee to 
each bicycle rider for use of the trail to offset the cost of 
maintaining the trail for bicycle use.
    Response: The NPS charges a $6.00 entrance fee to the paved loop 
road and the Cactus Forest Trail is not accessible to bicyclists except 
from this road. Thus, all bicyclists using this trail are already 
paying the park's entrance fee. The NPS believes that the impacts 
created by mountain bike use on this trail are not significant enough 
to warrant the cost of collecting an additional fee for this type of 
use. In addition, some of the maintenance work done on the trail is 
donated by local mountain bike user groups at little to no expense to 
the NPS.

Regulatory Flexibility Act

    The Department of the Interior certifies that this document will 
not have a significant economic effect on a substantial number of small 
entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.).
    There are no businesses in the surrounding area economically 
dependent on continued mountain bike use on this trail. The park does 
not have any mountain bike rental concessioners and the users are 
mainly private individuals using the trail for recreational purposes.

Small Business Regulatory Enforcement Fairness Act (SBREFA)

    This rule is not a major rule under 5 U.S.C. 804(2), the Small 
Business Regulatory Enforcement Fairness Act. This rule:
    a. Does not have an annual effect on the economy of $100 million or 
more.
    b. Will not cause a major increase in costs or prices for 
consumers, individual industries, Federal, State, or local government 
agencies, or geographic regions.
    c. Does not have significant adverse effects on competition, 
employment, investment, productivity, innovation, or the ability of

    This rule does not impose an unfunded mandate on State, local, or 
tribal governments or the private sector of more than $100 million per 
year. The rule does not have a significant or unique effect on State, 
local or tribal governments or the private sector.

Takings (Executive Order 12630)

    In accordance with Executive Order 12630, the rule does not have 
significant takings implications. A taking implications assessment is 
not required. No taking of personal property will occur as a result of 
this rule.

Federalism (Executive Order 13132)

    In accordance with Executive Order 13132, the rule does not have 
sufficient federalism implications to warrant the preparation of a 
Federalism Assessment. This Final rule only affects use of NPS 
administered lands and waters. It has no outside effects on other areas 
and only allows use within a small portion of the park.

Civil Justice Reform (Executive Order 12988)

    In accordance with Executive Order 12988, the Office of the 
Solicitor has determined that this rule does not unduly burden the 
judicial system and meets the requirements of sections 3(a) and 3(b)(2) 
of the Order.

Paperwork Reduction Act

    This regulation does not require an information collection from 10 
or more parties and a submission under the Paperwork Reduction Act is

National Environmental Policy Act

    The National Park Service has analyzed this rule in accordance with 
the criteria of the National Environmental Policy Act and has prepared 
an Environmental Assessment (EA). A copy of the EA is available by 
contacting the Superintendent, Saguaro National Park, 3693 South Old 
Spanish Trail, Tucson, Arizona 85730-5601. The EA may also be viewed 
via the internet at http://www.nps.gov/sagu/CactusTrailEA.pdf.

Government-to-Government Relationship with Tribes

    In accordance with the President's memorandum of April 29, 1994, 
``Government to Government Relations with Native American Tribal 
Governments'' (59 FR 22951) and 512 DM 2:
    We have evaluated potential effects on federally recognized Indian 
tribes

[[Page 50077]]

and have determined that there are no potential effects. Affiliated 
Native American tribes were contacted by letter dated July 12, 2002 to 
solicit any interests or concerns with the proposed action. Two tribes 
responded; the Tohono O'odham and the Hopi Tribes. Both tribes 
expressed concern that archeological resources be surveyed for impacts 
from this proposed bicycle use. The NPS has determined that the 
archeological resources will not sustain adverse impacts and has 
indicated this in writing to the tribes.

Clarity of Rule

    Executive Order 12866 requires each agency to write regulations 
that are easy to understand. We invite your comments on how to make 
this rule easier to understand, including answers to questions such as 
the following: (1) Are the requirements in the rule clearly stated? (2) 
Does the rule contain technical language or jargon that interferes with 
its clarity? (3) Does the format of the rule (grouping and order of 
sections, use of headings, paragraphing, etc.) aid or reduce its 
clarity? (4) Would the rule be easier to read if it were divided into 
more (but shorter) sections? (A ``section'' appears in bold type and is 
preceded by the symbol ``Sec.  '' and a numbered heading; for example 
Sec.  7.11 Saguaro National Park.) (5) Is the description of the rule 
in the Supplementary Information section of the preamble helpful in 
understanding the proposed rule? What else could we do to make the rule 
easier to understand?
