Graminoid cover averaged 28 percent for one stand sampled in the type 

 (Table A), Including pinegrass (20) and elk sedge (7). Forb cover was 

 17 percent, dominated by glacier-lily (6), heartleaf arnica (4), sitka 

 valerian (Valeri ana sitchensis , 3) and Virginia strawberry (2). Tree 

 cover averaged about 70 percent, entirely serai Dougles-fir, with one 

 percent cover of subalpine fir seedlings in the understory. 



The Abi las/Cal rub habitat type occurred on the Zc and Zd gravelly, 

 cobbly silty loam soils, 15-50 percent slope and greater than 50 

 percent slope. 



Subalpine Fir/Grous e Whortl eherry (Ab i las/Vac sco) Habitat Type. The 

 Abi las/Vac sco habitat type is the most common forest type in the 

 area, found at elevations of 6620 to 7870 feet in the permit area. It 

 is found on well-drained, gentle to moderate slopes and ridges of 

 variable aspect, bordered on drier sites by Fes sea/Fes ida, Abi 

 las/Cal rub and Abi las/Car gey, and on moister sites by Abi las/Xer 

 ten and other moist subalpine fir habitat types. 



Graminoid cover averaged 11 percent for four transects sampled in the 

 type, primarily pinegrass (8) and elk sedge (2). Forb cover averaged 

 only 5 percent, dominated by heartleaf arnica (2) end sitka valerian 

 (1). Other conspicuous forbs were glacier-lily, roundleaf violet 

 ( Viola orbiculata) and Virginia strawberry. Shrub cover averaged 43 

 percent, almost entirely grouse whortleberry. Tree cover averaged
