<br />CHAPTERTHREE Attecteld Enuironmem ` <br /> <br />occur along the portion of the pipeline at Davis Point, which has not been cover~:d in previous <br /> <br />surveys. , <br />Uinta Basin Hookless cactus (Sclerocacrus glaucus) is a listed threatened species and occurs on <br />rocky hills, mesa slopes, and alluvial benches in desert shrub communities, at e1~^vations of 4,500 <br />to 6,000 feet. It is mapped as occurring within the Pazachute Creek Valley (Sparkman et al. <br />1997), but is not known to occur in the vicinity of the project facilities (CNHP 1998). <br /> <br />Other Special Status Pant Species <br />Several additional raze or sensitive plant species occur in the study azea. Botanical surveys at the , <br />Piceance Site and northern eight miles of the pipeline did not specifically target these species, or <br />record locations, but their presence was noted. Botanical surveys were not conducted for the <br /> <br />remainder of the pipeline route. ' <br />Information on known occurrence of the raze or sensitive plants was obtained from the CNHP <br />database. Dragon milkvetch occurs on shale barrens of the Green River formation, including the <br />Piceance Site and near the pipeline corridor at the West Fork of Parachute Creek. Utah fescue is <br />found on moderate to steep exposed slopes or on talus at the base of slopes and also on relatively <br />moist, rocky streambanks on soils of the Green River shale formation and Uinta :sandstone , <br />formation. Populations of Utah fescue have been identified along Barnes Ridge near the middle <br />of the project pipeline corridor. Piceance bladderpod is endemic to open areas on shales in the <br />Piceance Basin, and has been reported from an azea near the pipeline corridor between the ' <br />Greasewood Compressor Station and southern crossing of Piceance Creek. Sun-loving <br />meadowrue and Arapien stickleaf (Sevier blazing star) both occur on steeply sloping and <br />constantly moving talus or scree slopes of the Green River shale formation. Both have been ' <br />recorded on the slopes of Pazachute Creek within 1 to 2 miles of the pipeline route. Hanging <br />garden sullivantia occurs at seeps and hanging gazdens in Parachute Creek, and is known from <br />one site within a mile of the pipeline in upper Pazachute Creek Valley. Utah MoLntain lilac has <br />been reported from sites about 2 miles east of the Parachute Creek Valley. <br /> ' <br />3.11 CULTURAL AND PALEONTOLOGICAL RESOURCES <br />3.11.1 Study Area <br />The study area for cultural and paleontological resources consists of the approximately <br />3,750-acre portion of the western lease azea that has been subjected to an intensive pedestrian <br />inventory (BLM Class III) for cultural resources, the pipeline corridor as presente~I in the Mine <br />Plan (Steigers 1998b), and the Pazachute plant site. , <br />3.11.2 Sources of Information <br />The discussion on existing conditions that follows is drawn from various environmental ' <br />documents and reports prepazed for neazby projects, cultural resources survey reports for these <br />projects, and site and report files at the Office of Archaeology and Historic Preservation, <br />Colorado Historical Society, Denver. <br />3-44 Threatened and Endangen:d Species <br />
