RESULTS <br />Total herbaceous cover at the combined Bear Mine sites 1 and 2 was sampled at <br />40.1% (see Table 3). Of that amount, perennial, non-noxious plant species contributed <br />36.4% absolute cover (90.8% of the total vegetative cover). These results are very <br />similar to those measured last year (see chart below). Annual grasses contributed 0.490 <br />relative cover while annual/biennial forbs contributed 6.6%. Noxious weeds were <br />intercepted only 0.8% (absolute cover) of the time, slightly below last year's value of <br />1.5%. Total cover (vegetation + rock + litter) was measured at 79.8%. <br />Comparison of 1992, 1993 absolute cover values <br />Cate 1922 1~ <br />Total Cover 80.4% 79.8% <br />• (= veg. + litter + rock) <br />Total vegetative cover 39.8% 40.1% <br />Perennial, non-noxious cover 35.7% 36.4% <br />Perennial grass cover 27.4% 28.0% <br />Annual grass cover 0.1% 0.2% <br />Perennial forb cover 8.3% 8.4% <br />Annual, biennial forb cover 2.5% 2.7% <br />Noxious weeds 1.5% 0.8% <br />Twenty-eight herbaceous species were encountered during cover sampling of <br />which thirteen were perennial grass species, two were annual grass species, six were <br />perennial forb species, four were annual/biennial forb species, and three were noxious <br />weed species.
