4-33 4.5 VEGETATION ASSESSMENT • This report presents, discusses, and summarizes data on vegetation types proposed to be affected by mining related activities planned for areas within a permit revision to the Munger Canyon permit (C-020-81). Specifically, a facilities complex would be built - at the mouth of Munger Canyon and require additional areas out- side the existing permit boundary. A refuse area is proposed for a site approximately one mile south of the mouth of Munger Canyon and would be connected to the central development by a service road. Additionally, a coal conveyor transport system would extend south from the McClane Canyon Mine (Permit No. C-004- 81) to the proposed facilities site at Dlunger Canyon. These proposed developments would affect some acreage of six vegetation types within the area of the permit revision. Th~~ planned refuse disposal facility would affect four vegetation types. They include four shrublands: Shadscale Cheatgrass, Shadscale Wildrye, and small areas of Gardner 3altbush and Juni- • per Woodland. The first two vegetation types per Colorado Mined Land Reclamation (CMLR) direction were quantitatively sampled for vegetation cover, production, and woody plant density during the 1981 growing season. A premising inventory approach was used to establish standards for revegetation success. The latter two vegetation types, Gapdrier Saltbush and Juniper Woodland, per CMLR direction were qualita~:ively de5¢ribe~ from limited quanti- tative data on cover and density. -The proposed central facilities would affect Greasewood Shrublands and Agricultural area S. These two latter vegetation types would be disturbed both within the permit revision area as well as within the area described in the existing Munger Canyon permit. Likewise, small areas of Big Sagebrush Shrubland, Juniper Woodland, and Shadscale Shrubland vegetation types within the Munger Canyon permit area would be potentially affected. The major disturbance within the Munger Canyon permit area is for existing disturbed . sites.
