• PLOT SPECIES COMPOSITION <br />Four species were found in more than half of the Valley Bottum plots: Ducrylis <br />glomerutu, Bromopsls inPrmis, Polygonum douglusii, and Pou prutensis. Three of <br />these most frequently encountered species were perennial grasses, the fourth being an <br />annual forb. Ductylis Rlomeruto and Brnmopsis inermis were the dominant species in <br />eleven of the I S (73.3%) plots while Polygonum dnuglusil and Pou prutensis were only <br />encountered in lower amounts and never dominated a plot. The dominant species was a <br />perennial species in all but 2 of the plots (those two plots were dominated by <br />Verhuscum thnpstts). Annual and biennial species comprised only 15.7% of the <br />estimated relative cover, and four of the five species having an estimated relative cover <br />exceeding 3 % were perennial grasses. <br />• Only one species, Elytrigiu repens, was found to dominate more than one <br />Hillside plot. Verbascum thupsus was the only nun-perennial species to he dominant <br />in a plot. Of the six species with an estimated relative cover exceeding 3%, four were <br />perennial grasses. These four species were encountered in three or more of the six <br />plots while the two biennial fortis with greater than 3% cover were only in two plots <br />each. <br />COVER AND SPECIES COMPOSITION' PROGRESS TOWARD SUCCESS <br />As noted above, cover values for plant species and litter, nxk, and hare ground <br />were estimated but should only he considered to he rough representations of the overall <br />community value. In spite of their shurtcomtngs in precision, cover estimates for the <br />plots can he discussed and compared from year to year. In plots from both areas. <br />annual and biennial species comprise over 45% of the total diversity. However, their <br />. estimated relative cover percentages are lower.
