Woody plant density measurements in 1999 differed from 1987 as suffruticose species were <br />not measured consistent with Guidelines for Compliance with Land Use and Vegetation <br />Requirements for Coal Mining. Succulents were also not included in the density calculations. <br />Mean density for the type was 17.23 stems /50m2 or 2,517 stems /acre (Table 2.04.10 -23). <br />Sagebrush dominated with an average density of 17 stems /50m2 or (2,483 stems /acre). Other <br />species included Utah juniper with 0.03 stems /50m2 or (12 stems /acre) and four -wing <br />saltbrush with 0.2 stems /50m2 or (29 stems /acre). <br />Nineteen species occurred in the cover samples, however, only 4 species had relative cover <br />values of 1 percent or greater. Grasses (including annuals) comprised 6 of the species (see <br />Table 2.04.10 -21), while annual /biennial /perennial forbs totaled 4. Five shrubs occurred in the <br />cover samples, as did two succulent and two trees. <br />(Revised October 2009) 2.04.10-80 <br />
