in the Ponderosa Pine-Pinyon-Juniper Woodland vegetation type, this area <br />had a total average basal cover of 19.1 percent dominated by basal grass <br />cover of 5.3 percent and lesser amounts of tree, shrub and forb cover. <br />Sample adequacy was calculated at 20 samples while a total of 60 samples <br />were taken. Refer to Exhibit 11, Vegetation Inventory for detailed <br />information regarding this reference area. <br />Coal Loadout Reference Area. As with the refuse disposal site, the coal <br />Loadout site is located entirely within the Grassland vegetation type and <br />was entirely disturbed prior to the initial vegetation inventory conducted <br />in 1980. A vegetation reference area for the coal Loadout was selected <br />based upon similarities to the Loadout area and the fact that it had not <br />been previously disturbed. The reference area for the coal Loadout is <br />located on the east side of the coal Loadout site as shown on the Loadout <br />Area Soils Map, (Map 15). <br />Total basal cover within this area was 19.35 percent at the time sampling <br />was conducted and was dominated by grasses with a basal grass cover of <br />9.01 percent, followed by forbs with a basal forb cover of 5.04 percent. <br />Sample adequacy was calculated to be 18 samples and 18 samples were <br />collected for the site. Refer to Exhibit 11, Vegetation Inventory for <br />detailed descriptions and information regarding this reference area. <br />Threatened and Endangered Species <br />In 1980, when the original vegetation inventory was conducted at the site, <br />a comprehensive vascular plant inventory was performed. A total of 130 <br />species were identified within the mine and Loadout areas. They included <br />6 tree species, 22 shrub or sub-shrub species, 13 forbs and 29 graminoids. <br />None of the species identified were listed on the Federal Threatened or <br />Endangered Species list in 1980. <br />Potential Forage Production and Range Condition <br />During 1979 and 1980, the Soil Conservation Service in Canon City, <br />~, <br />Colorado conducted preliminary vegetation surveys within the Southfield <br />mine area. These surveys are included within Exhibit 11, Vegetation <br />2.04.10-5R Revised - August, 1990 <br />
