Name: Populus tremuloides / Carex pellita Forest
Reference: Western Ecology Working Group of...
Description: This association is a wide-ranging, linear or small-patch community type, found in eastern Washington and Oregon in the Columbia Basin, Okanogan Highlands, and the Blue Mountains. It is associated with ephemeral depressions, wetland sites, organic soils, shallow water tables, and with low-gradient headwater streams. Elevations range from 549 to 1647 m (1800-5400 feet). This is an open forest dominated by Populus tremuloides occasionally with Pinus contorta var. latifolia or Betula papyrifera in the northern portions of its range or with Pinus ponderosa in Oregon or Betula occidentalis in the Columbia Basin. The understory is graminoid-dominated. Carex pellita (= Carex lanuginosa) is indicative of this community type with high cover (well over 25% cover) in higher condition sites. Carex microptera, Carex nebrascensis, Calamagrostis canadensis, Elymus glaucus, and Poa pratensis are low cover sedge-grass associates. Forbs are frequent but rarely abundant. Shrub cover is typical low with Salix boothii, Cornus sericea, and Rosa gymnocarpa frequent in northern sites and Cornus sericea and Symphoricarpos albus on warmer sites.
