Name: Pinus albicaulis - Pinus contorta var. latifolia / Penstemon laetus Forest
Reference: Western Ecology Working Group of...
Description: This subalpine woodland is found in Oregon's southeastern Cascades at elevations of 2135-2750 m (7000-9000 feet) and may occur in California. Aspects are variable with slopes 3-20%. Soils are poorly developed gravels and coarse sand over tuffs, breccias, and basalt. The canopy is dominated by <i>Pinus contorta</i> (5-30% cover) and <i>Pinus albicaulis</i> (1-30% cover). There is a marked absence of shrubs, although <i>Arctostaphylos nevadensis</i> may occasionally appear. The herbaceous layer consists of <i>Carex inops ssp. inops, Poa wheeleri</i>, and <i>Penstemon laetus</i>, all of which average 0-10% cover. <i>Achnatherum occidentale ssp. occidentale (= Stipa occidentalis)</i> and <i>Elymus elymoides ssp. elymoides (= Sitanion hystrix)</i> are sometimes in the understory. Both pines have moderate resistance to surface fires, but if the canopy is dense, crown fires will kill most trees.
