BIOLOGICAL ASSESSMENT AND BIOLOGICAL EVALUATION FOR THE 2015 JOE’S VALLEY BOULDERING PROJECT ENVIRONMENTAL ASSESSMENT MANTI-LA SAL NATIONAL FOREST FERRON/PRICE RANGER DISTRICT EMERY COUNTY, UTAH Prepared by: ________________________________________ Date________________ Jeff Jewkes, Wildlife Biologist Reviewed by: _______________________________________ Date ________________ Kim Anderson, Forest Ecologist ________________________________________ Date ________________ Pamela Manders, Forest Fisheries Biologist Joe’s Valley Bouldering Project Biological Assessment and Biological Evaluation Page 1 I. INTRODUCTION The purpose of this Biological Assessment/Biological Evaluation (BA/BE) is to review the potential effects of the Joe’s Valley Bouldering Project on threatened, endangered, or proposed plant and animal species (TEP) and to determine whether consultation with the U.S. Fish and Wildlife Service (USFWS) is necessary. The Endangered Species Act of 1973 (PL 93-205, as amended) requires federal agencies to ensure that any activities they authorize, fund, or carry out, do not jeopardize the continued existence of any wildlife species federally listed as Threatened or Endangered (Section 7). Consultation with the USFWS is required if threatened or endangered (T&E) species, or their critical habitat may be affected by proposed actions. This BA/BE is prepared in accordance with legal requirements set forth under Section 7 of the Endangered Species Act (16 U.S.C. 1536 (c)), and follows standards established in the Forest Service Manual (FSM 2671.2 and 2672.4). The USDA, Forest Service has developed policy regarding the designation of sensitive plant and animal species (FSM 2670.32). A sensitive species is defined (FSM 2670.5) as those plant and animal species identified by the Regional Forester for which population viability is a concern as evidenced by: 1) significant current or predicted downward trends in population numbers or density or 2) significant current or predicted downward trends in habitat capability that would reduce a species' existing distribution. The Biological Evaluation is an analysis of which sensitive species may occur in the project area and whether any impacts on these species or their habitat are anticipated which will adversely affect their viability. II. DESCRIPTION OF THE PROPOSAL A. Summary of the Proposed Action The Ferron/Price Ranger District of the Manti-La Sal National Forest proposes to: Construct designated fire rings at dispersed campsites; dismantle and naturalize redundant user created fire rings. Approximately 12 fire rings would be installed. Contain dispersed campsites and parking areas as needed to minimize vehicle impacts to soils/vegetation and nearby riparian areas. Native rocks and/or barrier posts/rails would be utilized. Harden high use parking areas with road base to prevent soil erosion. Install a vault toilet facility at the angler access parking area in Straight Canyon (Left Fork). Install kiosks and signage promoting climbing ethics and “Leave No Trace” principles. Construct rock retaining walls at boulders to level landing areas; focusing on boulders receiving heavy use and/or located on slopes greater than 10%. Approximately 90 boulders would receive treatment. Joe’s Valley Bouldering Project Biological Assessment and Biological Evaluation Page 2 Develop a sustainable trail network by hardening trails to bouldering sites displaying obvious soil erosion with native rock; re-route access trails as needed to reduce grades; close and rehabilitate redundant trails. Approximately 2.5 miles of trail would receive treatment. Mark trail beginning points and install reassurance markers as needed so that trails are easily identified and followed. B. Purpose and Need Bouldering and associated camping at Joe’s Valley have contributed to recreation resource impacts throughout the area. Multiple informal trails, soil erosion, bare soil, vegetation trampling, and numerous fire sites are commonly observed impacts. Data for National Forest System (NFS) lands included in the Baseline Assessment documents the following: 60.6% (114) of the bouldering sites inventoried are located on NFS lands. 41 of these boulders were rated as receiving heavy use. 70 of these boulders are located on slopes in excess of 10%. 5.0 miles of informal trails are located on NFS lands. 1.8 miles of these 5.0 miles display obvious soil erosion. 28 parking areas are located on NFS lands. The purpose for this project is to mitigate current impacts to soils and vegetation in the Joe’s Valley Bouldering area while providing quality recreation opportunities and protecting resources. The need for this project is guided by legal requirements specified in Forest Plan General and Management Unit Direction below. Specifically: 1) There is a need to develop sustainable, resource sensitive access trails to bouldering sites. 2) There is a need to develop sustainable landing zones around boulders. 3) There is a need to contain motorized use at dispersed campsites and parking areas to protect resources and provide for user safety. C. Project Area Description/Affected Environment The proposed Joe’s Valley Bouldering Project is located in east-central Utah, approximately 9 miles northwest of the town of Orangeville, in Emery County, Utah. The action area boundary or analysis area for this BA/BE is the Joe’s Valley Bouldering area. The Joe’s Valley Bouldering area generally describes the region receiving bouldering use. Bouldering areas can be generally categorized into three geographical regions: Left Fork of Straight Canyon, along Utah highway State Route (SR) 29, Joe’s Valley Bouldering Project Biological Assessment and Biological Evaluation Page 3 Right Fork (Cottonwood Canyon, along Forest System Road (FSR 50040), and New Joe’s (Grimes Wash near Utah Highway 57) (see maps below). Topography is generally similar in all of the bouldering areas; characterized by rocky, rugged terrain in the vicinity of the roadway, with vertical cliff walls above the climbing areas. Elevation ranges from approximately 6,500 ft. – 8,200 ft. The vegetation within the project area varies slightly with topography and elevation with nine different cover types; however, the majority of the bouldering sites (161 out of 192) are within the Colorado Plateau Pinyon Juniper Woodland according to SWReGAP data (USGS 2004). The Description for the Colorado Plateau Pinyon-Juniper Woodland vegetation cover type found is listed listed below. The description is derived from the SWReGAP definitions of each vegetation cover type (USGS 2004). This cover type has not been ground-truthed and may differ from actual vegetation within the project area. Colorado Plateau Pinyon-Juniper Woodland This ecological system occurs in dry mountains and foothills of the Colorado Plateau region including the Western Slope of Colorado to the Wasatch Range, south to the Mogollon Rim of Arizona and east into the northwestern corner of New Mexico. It is typically found at lower elevations ranging from 4,900 to 8,000 ft. These woodlands occur on warm, dry sites on mountain slopes, mesas, plateaus, and ridges. Severe climatic events occurring during the growing season, such as frosts and drought, are thought to limit the distribution of pinyon- juniper woodlands to relatively narrow altitudinal belts on mountainsides. Soils supporting this system vary in texture ranging from stony, cobbly, gravelly sandy loams to clay loam or clay. Pinyon pine and/or Utah juniper dominate the tree canopy. In the southern portion of the Colorado Plateau in northern Arizona and northwestern New Mexico, one-seed juniper (Juniperus monosperma) and hybrids of juniper may dominate or codominate the tree canopy. Rocky Mountain juniper (Juniperus scopulorum) may codominate or replace Utah juniper at higher elevations. Understory layers are variable and may be dominated by shrubs, graminoids, or be absent. Associated species include greenleaf manzanita (Arctostaphylos patula), big sagebrush (Artemisia tridentata), littleleaf mountain mahogany, mountain mahogany (Cercocarpus montanus), blackbrush, Stansbury cliffrose (Purshia stansburiana), antelope bitterbrush (Purshia tridentata), Gambel oak (Quercus gambelii), blue grama (Bouteloua gracilis), James’ galleta (Pleuraphis jamesii), or muttongrass (Poa fendleriana). This system occurs at higher elevations than Great Basin Pinyon-Juniper Woodland and Colorado Plateau shrubland systems where sympatric. The Joe’s Valley Bouldering area is home to a variety of wildlife species including: elk, deer, bear, mountain lion, raptors, small mammals, and a variety of songbirds. The escarpment above the climbing areas is ideal nesting habitat for golden eagles and peregrine falcons.
