<br /> <br />species located within mountain-mahogany stands. Pasture sa~3e (A. <br />• frigida) and western ragweed (Ambrosia psilostachya) are dominant <br />fortis in Cercocarpus stands. Cheatgrass (B. tectorum), needle grass <br />(S. occidentalis), blue-grams (B. gracilis), and sedges (Carex <br />heliophila, C. foenea, and C. filifolia) are abundant in Cer~:ocarpus <br />stands. <br />The relative percent cover of mountain mahogany is 75-g!i% in the <br />more "pure" stands of Cercocarpus. Bare ground is common (1!i-30%) in <br />most areas within a mountain mahogany stand. Occassional ro~:ky outcrops <br /> exist through several stands. Cercocarpus stands persist on west- and <br /> east-facing slopes where grass and tree growth is often poor due to soil <br /> texture phenomena, and to exposure to wind. <br /> Douglas-Fir Type: <br />• This stand-type is predominately populated by douglas-fir (Pseudotsuga <br /> menziesii). The majority of douglas-fir trees are confined ~to north- and <br /> northeast-facing slopes, and in several sheltered areas alon!3 Ralston <br /> Creek. This stand type is quite dense (70-92% relative cover) with <br /> Pseudotsuga. The height of douglas-fir trees at the Schwartwalder <br /> project site average 7m (23 ft. ), and the range is quite variable <br /> (0.6-9.6m). Portions of the road cut through douglas-fir st:jnds on the <br /> western section of the site are repopulating the road embankments with <br /> young douglas-fir trees, and other shrubs. Other plants that are rela- <br /> tively frequent in this stand type are (Juniperus communis ssp.alpina), <br /> Ponderosa pine (P. ponderosa), red cedar (J. scopulorum), mom taro maple <br /> (Ater lab rum), mountain mahogany (C. montanus), and prairie sage (A. <br /> ludoviciana). <br /> <br />J- 7 <br />
