Introduced perennial (orbs contributed 0.7 percent while introduced perennial cool season <br />• grasses accounted for 0.5, moss accounted for 0.3 and native annual and biennial (orbs <br />accounted for 0.2 percent of total vegetation cover. <br />Total vegetation cover was 52.2 percent. Standing dead, litter, bare soil, and rock cover values <br />were 8.1, 22.6, 16.8 and 0.3 percent, respectively. Total species density averaged 25.5 species <br />per 100 sq. m. <br />HERBACEOUS PRODUCTION (TABLE 9i <br />Total. herbaceous production was 389.5 pounds per acre. <br />DISCUSSION <br />Climatic Conditions <br />The dry growing season of 2002 was followed by anear-average fall 2002 and a generally above- <br />average spring 2003 (Figures 6a and 6b). Although June and especially July were below <br />average, the average for the 12 months preceding late July sampling was slightly above average <br />(Figures 7a and 7b). Considering the previous six-months only (Figures 8a and 8b) the 2003 <br />figures are quite noticeably above average with the effects of the wet spring weighing heavily. <br />From a perspective of the previous four months only (Figures 9a and 9b) the effects of the dry <br />early summer brought the 2003 values down to average. As regards heat from January through <br />June, the year was very near average (Figure 10). <br />Cover <br />• <br />Observed cover values and derivation of the 2003 herbaceous cover standard are <br />compiled/documented in the table below: <br />Yoast 2003 <br />Using the Seneca II-W 2003 <br />Phase III Cover Performance Standard <br />Vegetation Type Mean Cover` 1sUall Ratio*" Adj.
