4 - 74 <br />4.5.15 SUMMARY <br />• A vegetation study was conducted at the McClave Canyon Mine during 1980 to collect data <br />and comply with the permitting requirement of the Colorado Surface Coal Mining Reclamation <br />Act. <br />The permit area has three vegetation types, each of which is affected by mining activity. <br />They include a Greasewood Shrubland, Shadscale Shrubland, and a Juniper Woodland. Each of <br />these vegetation types is common to the extensive areas of western Colorado and neighboring <br />Utah. A vegetation map was prepared, reference areas were located, and quantitative data <br />collected. Sampling was confined to an area around existing disturbances and to areas of future <br />disturbances as well as to each reference area. Vegetation factors quantified for the three <br />affected and reference areas included: cover, production, and shrub and tree density. See <br />Tables 4.5.25, 4.5-26, and 4.5.27. All sampling was in accordance with existing and proposed <br />regulations of the Office of Surface Mining and Colorado Mined Land Reclamation. <br />Sampling in all affected and reference areas for cover, production, and woody plant density <br />met OSM and CMLR adequacy requirements (see Section 4.5.15). All reference areas mer <br />• statistical adequacy requirements for comparability with respect to cover. Two of the reference <br />areas were slightly nonrepresentative of affected areas, because the reference areas had higher <br />production. No plant species federally listed as threatened or endangered were observed in the <br />permit area. The flora included one designated noxious weed, whitetop Cardaria Draba, which is <br />present in the Greasewood Shrubland vegetation type but has a limited cover. <br />• <br />Mo Volume 1 429-96 <br />
