Name: Crataegus douglasii / Rosa woodsii Wet Shrubland
Reference: NatureServe Biotics 2019
Description: This association occurs in the Columbia Basin along low-elevation, low-gradient streams with broad floodplains that are flooded seasonally. Due to the low gradients, however, the floodplains are rarely scoured. The association is composed of a partially closed canopy of the broad-leaved, deciduous tall-shrub <i>Crataegus douglasii</i>, which is typically 3-6 m tall. Occasional individuals of the broad-leaved deciduous trees <i>Populus tremuloides, Populus balsamifera ssp. trichocarpa, Betula occidentalis</i> or <i>Alnus incana</i> may occur, but they never dominate the stand. A broad-leaved, deciduous short-shrub layer is present, with varying amounts of cover. Common species include <i>Rosa woodsii, Salix exigua</i>, and <i>Amelanchier alnifolia</i>. The herbaceous layer is composed of perennial grasses, such as <i>Leymus cinereus, Deschampsia cespitosa</i>, and <i>Elymus glaucus</i>. Some <i>Carex</i> species do occur.
