Name: Betula occidentalis / Philadelphus lewisii - Symphoricarpos albus Shrubland
Reference: Western Ecology Working Group of...
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 Betula occidentalis trees or tall shrubs, 4 to 9 m (15-30 feet) tall, form a dense to open woody layer usually with Philadelphus lewisii and/or Symphoricarpos albus. The shrub layer sometimes contains high cover of Prunus virginiana, Ribes aureum, Clematis ligusticifolia, Rosa woodsii, Rosa nutkana, or Holodiscus discolor. Toxicodendron rydbergii is abundant on more moist sites. The sparse herbaceous layer can have Maianthemum stellatum in abundance.
