CWillow Carr 4eoetation Type <br />Affected Area <br />Cover dominant species were Salix exiqua (4.9%), Carex spp. <br />(4.2%), Cirsium arvense (4.2%), Mertensia spp. (5.8%), Solidago altissima <br />(9.7%), and Poa prratensis (3.2%) (Table 8). Forbs were diverse and <br />abundant. Total plant cover averaged 43.1%. Cover by litter and rock <br />was 19.70, and by plant -litter -rock was 62.9%. Bare ground averaged <br />58.6%. Sample adequacy for cover was met at 5 samples, although 15 <br />were taken (Table 2). <br />Forbs were the most productive species. The highest producer was <br />Ambrosia trifida, at 41.4 gms/m2, followed by Cirsium arvense (22.5 <br />gms/m2), Humulus lupulus (16.4 gms/mz), and Linaria vuloaris (15.7 gms/m2) <br />(Table 9). Highest producing grasses were Carex spp. (8.5 gms/m2), Poa <br />pratensis (7.7 gms/m2), and Poa spp. (6.0 gms/m2). Total average <br />production was 240 gms/m2. Sample adequacy was met at 11 samples; 15 <br />were obtained (Table 2). <br />Salix exiqua was the most dense shrub, at 2.8 shrubs/m2, or 74%, <br />followed by Rosa woodsii, at 1.0 shrubs/m2, or 26% (Table 10). These <br />were the only shrubs encountered in sampling. Average shrub density <br />was 3.8 shrubs/m2. <br />Reference Area <br />Cover dominant species included Salix exiqua (3.3%), Linaria <br />vulgaris (11.6%), Cynoglossum officinale (5.4%), Artemisia dracunculus <br />(5.2%), Cirsium arvense (4.5%), and Arcticum minus (4.3%) (Table 8). <br />In the grass category, Carex spp. provided the most cover, at 3.20. <br />Total plant cover averaged 36.8%. Cover by litter and rock was 15.50, <br />14 <br />
