Name: Symphoricarpos albus - Rosa nutkana Shrubland
Reference: NatureServe Biotics 2019
Description: This <i>Symphoricarpos albus</i> plant association is known from canyonlands of the Imnaha River and lower Snake River within northeastern Oregon, southeastern Washington, and west-central Idaho. The association occurs on lower to mid-slope positions of moderately steep to steep, north-facing footslopes below 915 m (3000 feet) elevation. Very deep silt or silt loam soils on these relatively moist sites are formed in loess accumulations over basalt colluvium or bedrock. The plant association is characterized by dense growth of <i>Symphoricarpos albus</i>. <i>Rosa nutkana</i> or <i>Rosa woodsii</i> are usually present. Deciduous shrubs are so abundant that growth of understory forbs and graminoids is limited. Associated understory species may include <i>Festuca idahoensis, Frasera albicaulis, Besseya rubra, Geum triflorum</i>, and <i>Lupinus sericeus</i>. Stands with potential for tree establishment are maintained as shrubland by periodic wildfire. On drier habitats, periodic wildfire will restrict expansion of the association into adjacent bunchgrass-dominated vegetation.
