Name: Abies lasiocarpa - Pinus albicaulis / Vaccinium scoparium Woodland
Reference: Pfister, R. D., B. L. Kovalchik,...
Description: This is an extensive forest type in much of the highest forest belt east of the Continental Divide in Montana and is also known from western Wyoming and as far west as eastern Oregon. It is found on all exposures at elevations ranging from 2200 to 3070 m (7200-10,075 feet). Soils are generally thin and poorly developed from a variety of parent materials and are usually acidic to very acidic in the surface layers. Soil textures range from gravelly loams to silts. Ground cover typically has moderate amounts of bare ground and rock. Tree cover is typically open, rarely exceeding 50% total over. <i>Abies lasiocarpa</i> shares dominance with <i>Pinus albicaulis</i> with 10-60% cover, averaging about 20-30%, each. Higher canopy cover occurs in more protected locations. Other tree species may be present and include <i>Picea engelmannii, Pinus flexilis</i>, and <i>Pinus contorta</i>. Understory growth is usually dominated by <i>Vaccinium scoparium</i>, and on drier sites <i>Carex geyeri</i> can be more abundant. <i>Arnica latifolia</i> is the only consistently present forb across all studies. This association is differentiated from pure <i>Pinus albicaulis</i> associations by the consistent codominance of <i>Abies lasiocarpa</i> in the overstory canopy.
