Coniferous Community




Douglas-fir (Pseudotsuga menziesii), white fir (Abies concolor), and aspen (Populus tremuloides) dominate this community, either in pure or in mixed stands, growing chiefly on north- to northeast- and northwest-facing slopes; the aspen reach as low as 1706 m (5600 ft) and the firs occur mostly above 1828 m (6000 ft). Achlorophyllous Corallorhiza spp. (coralroot orchid) are among the few plants able to flourish in the shade of dense stands of mixed conifers. Many small trees, shrubs, forbs, and grasses thrive in less dense stands or in openings between stands of trees in this community. Among them are those listed to the right.
