Name: Populus tremuloides / Carex pellita Riparian Forest
Reference: NatureServe Biotics 2019
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 <i>Populus tremuloides</i> occasionally with <i>Pinus contorta var. latifolia</i> or <i>Betula papyrifera</i> in the northern portions of its range or with <i>Pinus ponderosa</i> in Oregon or <i>Betula occidentalis</i> in the Columbia Basin. The understory is graminoid-dominated. <i>Carex pellita</i> is indicative of this community type with high cover (well over 25% cover) in higher condition sites. <i>Carex microptera, Carex nebrascensis, Calamagrostis canadensis, Elymus glaucus</i>, and <i>Poa pratensis</i> are low cover sedge-grass associates. Forbs are frequent but rarely abundant. Shrub cover is typical low with <i>Salix boothii, Cornus sericea</i>, and <i>Rosa gymnocarpa</i> frequent in northern sites and <i>Cornus sericea</i> and <i>Symphoricarpos albus</i> on warmer sites.
