Name: Physocarpus malvaceus - Symphoricarpos albus Shrubland
Reference: NatureServe Biotics 2019
Description: This association is known from canyonlands of the northern Wallowa Mountains, Imnaha River, and Snake River within northeastern Oregon, southeastern Washington, and west-central Idaho. The association occurs on upper slope positions of steep, northeast- to northwest-facing canyon slopes at 1125 to 1375 m (3700-4500 feet) elevation. Deep soils on these relatively moist, shaded sites are formed from basalt colluvium. <i>Physocarpus malvaceus</i> is the dominant shrub species (mean cover exceeds 80%). <i>Symphoricarpos albus</i> is consistently present. Other associated shrub species include <i>Amelanchier alnifolia, Prunus virginiana</i>, and <i>Philadelphus lewisii</i>. Shrubs are so abundant that growth of understory forbs and graminoids is limited. This <i>Physocarpus malvaceus</i> association is distinguished from <i>~Pseudotsuga menziesii / Physocarpus malvaceus</i> Forest (CEGL000447)$$ by the absence of trees. Periodic fire may serve to maintain this deciduous shrubland vegetation by controlling the establishment of trees.
