Wetland information:Wetlands:soils intermittently flooded. Water chemistry: fresh. Streamsides. Cowardin class: Palustrine forested wetland. raised terraces, morainal rocks and boulders, ridges. Soils granitic, metasediment-derived. The national inventory of wetland plants (Reed 1988) lists subalpine fir as a FACW*.
Upland information: Uplands:raised terraces, morainal rocks and boulders, ridges. Soils granitic, metasediment-derived. The national inventory of wetland plants (Reed 1988) lists subalpine fir as a FACW*.

Comments:Subalpine fir forms a series in OR, WA, and Rocky Mountains, but its presence in CA was not verified until 1970 (Sawyer et al. 1970). Earlier reports in the manuals were based on specimens of Pacific silver fir collected at English Peak in the Marble Mountains (Haddock 1961). Since 1970 four additional stands have been identified; three in the Marble Mountains (Sawyer & Cope 19 2). The newest and most southern stand occurs between Virginia Lake and Marvis Lake in the Scott Mountains (Sawyer 1987). Subalpine fir is rare (a CNPS List 2 plant) in CA (Skinner & Pavlik 1994).
Plot based descriptions:Keeler-Wolf (1984b, 1989f), Sawyer & Thornburgh (1971) in Keeler-Wolf (1990e) summarize surveys in Salmon Mountains including the Sugar Creek candidate RNA. Keeler-Wolf (1984b) maps stands dominated by subalpine fir in Sugar Creek. Sawyer & Thornburgh ( 969) report density and size, and De Jager (1991) age patterns for stands in the Duck Lake Creek drainage in Siskiyou Co. m-KlaR, su-KlaR.
