• Date Approved: 1983, amended 1991 and 1993. <br />Decision Number/Page: Area 4B, Area 4D, Area 9A. <br />Decision Language: Area 4B: Wildlife habitat management for one or more species of <br />wildlife. Semi-primitive non-motorized, semi-primitive motorized and roaded natural <br />recreation opportunities will be provided. Livestock grazing will be compatible with wildlife <br />habitat management. Vegetation treatment will enhance plant and animal diversity. <br />Area 41): Aspen management. Area is managed to maintain or improve aspen and to <br />provide wood fiber, wildlife habitat, visual quality and plant and animal diversity. Semi- <br />primitive non-motorized, semi-primitive motorized and roaded natural recreation <br />opportunities will be provided. Livestock grazing is compatible with aspen management. <br />Area 9A: Aquatic/riparian ecosystem management to provide healthy, self-perpetuating <br />plant communities, acceptable water quality standards, fish and wildlife habitats, and stable <br />stream channels. Mineral activities may occur but must minimize disturbance to riparian <br />areas, and timely and effective rehabilitation and restoration of the riparian areas to a state of <br />productivity comparable to that before disturbance must be initiated. <br />STANDARDS FOR PUBLIC LAND HEALTH: In January 1997, Colorado BLM approved the <br />Standards for Public Land Health. Standards describe conditions needed to sustain public land <br />• health and relate to all uses of the public lands. A fmding for each standard will be made in the <br />environmental analysis (next section). <br />• <br /> <br />Standard <br />-DefinonlSta m of = = r °' _ <br />77 <br /> Upland soils exhibit infiltration and permeability rates that are appropriate to soil type, climate, <br />#1 Upland Soils landform, and geologic processes. Adequate soil infiltration and permeability allows for the <br /> accumulation of soil moisture necessary for optimal plant growth and vigor, and minimizes <br /> surface runoff. <br /> Riparian systems associated with both running and standing water, function properly and have <br />#2 Riparian the ability to recover from major surface disturbances such as fire, severe grazing, or 100-year <br />Systems floods. Riparian vegetation captures sediment, and provides forage, habitat and bio-diversity. <br /> Water quality is improved or maintained. Stable soils store and release water slowly. <br /> Healthy, productive plant and animal communities of native and other desirable species are <br />#3 Plant and maintained at viable population levels commensurate with the species and habitat's potential. <br />Animal Plants and animals at both the community and population level are productive, resilient, <br />Communities diverse, vigorous, and able to reproduce and sustain natural fluctuations, and ecological <br /> processes. <br />#4 Threatened Special status, threatened and endangered species (federal and state), and other plants and <br />and Endangered animals officially designated by the BLM, and their habitats are maintained or enhanced by <br />Species sustaining healthy, native plant and animal communities. <br /> The water quality of all water bodies, including ground water where applicable, located on or <br /> influenced by BLM lands will achieve or exceed the Water Quality Standards established by <br />#5 Water the State of Colorado. Water Quality Standards for surface and ground waters include the <br />Quality designated beneficial uses, numeric criteria, narrative criteria, and anti-degradation <br /> requirements set forth under State law as found in (5 CCR 1002-8), as required by Section <br /> 303(c) of the Clean Water Act. <br />DOI-BLM-CO-S050-2010- 0017 EA Page 15 of 43 May 2010
