<br />xevised 1/26/80 <br />Section 785.19(c) Continued <br />Vegetation <br />In connection with the vegetation information required by 30 CFR 779.19(a) <br />aerial photographs sere utilized to map vegetation carnmuLities. The <br />study area sham on the Eclanan Pazk Stream Channel Cross Sections (Map 51) <br />was cmQared with plant camrninities shown on the Eckman Pazk vegetation <br />Map (Map 16). The Meadow Range site was found to correspond closer to <br />the study area than any other vegetation type. <br />• Field data collected in 1977 (Table 32) and 1979 (Table 38) was examined <br />for differences >n species presence and ccnQosition. Data collected <br />fran field studies indicates sedges, meadaa fescue, and horsetail were <br />the only species restricted to the meadow vegetation camnmity. Although <br />not restricted to this type, timothy, elk thistle, rush and clover were <br />found in larger amounts in the meadow type than in the other types. The <br />most obvious difference between species cc~g~osition was an increase in <br />the abundance of rushes. Table 38 indicates that the species yielding <br />significant amounts of forage production on this site aze rushes (30 <br />percent production) and sedges (14 percent production). According to <br />the 0.5M Technical Guideline, sedges and reeds are not useful for grazing <br />or cropping, and the presence of these species indicates there is no <br />subirrigation or flood inundation in the study area. <br />785-9(v) <br />
