12 <br />C <br /> <br />Reference Area • <br />Cover dominant species were the shrub Quercus oambelii (5.8`,6), <br />and the sedge Carex spp. (1.4%) (Table 5). Cercocarpus montanus was <br />an important shrub (0.9%) and Muhlenberqia montana an important grass <br />(0.9%). Total plant cover averaged 11.8%, cover by litter and rock <br />was 79.1%, and by plant-litter-rock was 90.9%. Bare ground averaged <br />17.5%. Sample adequacy was met at 13 samples, 22 were taken (Table 2). <br />Carex spp. was the high producer, at 1.3 gms/mz (Table 6). <br />Andropogon scoparium produced 0.9 gms/mz, Muhlenbergia montana 0.7 <br />gms/m2, and Clematis hirsutissima 0.7 gms/mz. Total production <br />averaged 7.3 gms/mz. Sample adequacy was met at 17 samples, and 22 <br />were obtained (Table 2). <br />uercus gamhelii was the mast dense shrub, at 2.2 shrubs/mz, or <br />60% of all shrubs (Table 7). Cercocarpus montanus and Ribes inerme -~ <br />each had densities of 0.6 shrubs/mz, or 16%. Average shrub density was <br />3.8 shrubs/mz. <br />Tree density data showed Pinus ponderosa as the most dense, <br />with 120 trees/ha, or 7% (Table 7). Pinus edulis had a density of <br />80 trees/ha, or 5%, and Pseudotsuga menziesii had 40 trees/ha, or 20. <br />P. menziesii had a very high sapling density, however, at 1,000 trees/ <br />ha, or 60%. P. ponderosa had the next highest sapling density, at 200 <br />trees/ha ,or 12%. P. edulis had only 40 trees/ha. <br />The dominants for bath the affected area and reference area <br />were Pinus ponderosa, Pseudotsuga menziesii, and Quercus gambelii. The <br />majority of P. menziesii trees were in the sapling stage in the reference <br />area. Important understory species in the affected area were Carex spp. <br /> <br />
