Name: Betula occidentalis / Philadelphus lewisii Shrubland
Reference: Western Ecology Working Group of...
Description: This is a riparian, bottomland association found on seasonal streams to third-order perennial streams, in small, U-shaped to V-shaped, valley bottoms. Occurrences occur at relatively low elevations in the mountains of eastern Oregon and adjacent Idaho. Betula occidentalis forms a low, patchy canopy along the stream, and occasionally spreads out throughout the floodplain with cover ranging from 60-90%. Philadelphus lewisii is found throughout the bottomland, creating shrub thickets with overall cover ranging from 20-40%. Other trees and tall shrubs are rare, but can include Salix species (Salix lemmonii, Salix exigua, Salix geyeriana, or Salix lasiolepis), Cornus sericea, or Crataegus douglasii. Low shrubs (Rosa woodsii, Ribes aureum, Toxicodendron radicans), and graminoids (Elymus glaucus, Carex douglasii, Carex amplifolia, Juncus balticus) dominate the understory, along with some non-native grasses and forbs (Bromus tectorum, Poa pratensis, Verbascum thapsus and Solanum dulcamara).
