Total vegetation cover was 56.9 percent. Standing dead, litter, bare soil, and rock averaged 4.6, <br />• 26.6, 11.7, and 0.2 percents of total vegetation cover, respectively. Species density averaged <br />25.7 species per 100 sq.m. <br />HERBACEOUS PRODUCTION (TABLE 9) <br />Total herbaceous production was 717.3 pounds per acre. <br />DISCUSSION <br />Climatic Conditions <br />The year preceding sampling in July 2004 included a fall with two wet months ((September and <br />November); 2004 proceeded up to sampling in late July with mostly below average monthly <br />precipitation (Figures 6a and 6b). April 2004 was about average, which may have prevented <br />2004 vegetation growth from being much lower than it was. When compared to other years in <br />which monitoring has occurred back to 1989, the cumulative 12 months previous precipitation <br />total ranked 2004 in the lower third relative to other years in that period (Figures 7a and 7b). The <br />cumulative six month (Figure 8b) and four month (Figure 9b) precipitation values back to 1989 <br />show that 2004 was about 20 to 25% below the 15-year average. With regard to temperature <br />• (Figure 10), cumulative January through June 2004 warmth was only very slightly above average <br />meaning that statistically, warmth was also close to "normal." <br />• <br />Cover <br />Observed cover values and derivation of the 2004 herbaceous cover standard are <br />compiled/documented in the table below: <br />Seneca IIW 2004 <br />Phase III Cover Performance Standard <br />Vegetation Type Mean Cover* 1stla11 Ratio** Adj.
