Name: Betula occidentalis / Philadelphus lewisii - Symphoricarpos albus Wet Shrubland
Reference: NatureServe Biotics 2019
Description: This riparian shrubland or short woodland community is known from low elevations of 427 to 1037 m (1400-3400 feet) in the Columbia Plateau and adjacent foothills in Oregon and Washington. This association generally appears well below treeline and within steppe or shrub-steppe settings, and is usually found on upper stream terraces, although it can occur on toeslopes or in the active floodplain. Short <i>Betula occidentalis</i> trees or tall shrubs, 4 to 9 m (15-30 feet) tall, form a dense to open woody layer usually with <i>Philadelphus lewisii</i> and/or <i>Symphoricarpos albus</i>. The shrub layer sometimes contains high cover of <i>Prunus virginiana, Ribes aureum, Clematis ligusticifolia, Rosa woodsii, Rosa nutkana</i>, or <i>Holodiscus discolor</i>. <i>Toxicodendron rydbergii</i> is abundant on more moist sites. The sparse herbaceous layer can have <i>Maianthemum stellatum</i> in abundance.
