the shallow well-drained soils of the Zyme-Rock outcrop complex (12 to 65 percent slopes). Runoff potential of the Zyme-Rock outcrop soils is rapid and the hazazd of erosion is high. No permanent surface water features or ripazian habitats aze in or immediately adjacent to the project azea. Drainage is towards the Animas River Valley 0.4 miles east of the project azea. Pinon-juniper woodland is located on the northern extent of the proposed project azea and is characterized by mature pinon pine and Utah juniper. Tree canopy cover is sparse (ranging from 5 to 10%) in a majority of the affected area where logging occurred (approximately 10 years ago). Associated shrubs include mountain mahogany, antelope bitterbrush, Gambel's oak, and big sagebrush. Cover in the undisturbed pinon juniper woodland on the steep south-facing slopes and along the remainder of the hilltop ranges from 50 to 60 percent. Grasses and fortis occurring in the project area include Indian ricegrass, blue grama, and galleta with phlox, actinea and Indian paintbrush in the openings. No invasive species or noxious weeds were identified in the proposed project azea. A complete list of flora associated with the proposed project area is provided in Appendix B of [his report. Wildlife in the project azea includes a variety of mammals, birds, and reptiles common to the San Juan Basin. The Project azea lies within Colorado Division of Wildlife's Game Management Unit (GMU) # 741. Summary statistics for mammals occurring within this GMU are provided in Appendix C. Evidence of deer and coyote (scat and tracks) were observed in the project area. Appendix D lists common wildlife with potential to occur in the project azea. No raptors or raptor nests were seen along or immediately adjacent to the project area. Raptor foraging and perching habitat occurs north of the project azea in the mature pinon-juniper woodland in the project azea. No prairie dog towns occur in proposed project area. 4.0 THREATENED AND ENDANGERED FLORA In following the guidelines of the Endangered Species Act of 1973, as amended, a search was made for TES flora species with potential to occur in the project area. Southwest Land Services and Ecosphere informally consulted with Tony Gurzick Area Supervisor of the Colorado Division of Wildlife. No Colorado state or federally listed TES flora species are known to exist and only four TES flora species have the potential to occur in the project area. No federal TES species were found during the biological survey of the project area. 4.1 TES Flora Eliminated from Detailed Consideration Listed in Table 1.0 aze TES flora species [hat aze known from, or have the potential to occur in, the project area but have been eliminated from detailed consideration in this report. The table provides specific reasons for the elimination. 3
