Name:
Atriplex canescens - Ericameria nauseosa Shrub & Herb Wash-Arroyo Group
Reference:
NatureServe Biotics 2019
Description:
This is a sparsely to densely vegetated group that occurs along dry watercourses that experience periodic flash flooding. These are shrublands dominated by <i>Atriplex canescens, Atriplex confertifolia, Brickellia</i> spp., <i>Ephedra</i> spp., <i>Ericameria nauseosa</i>, and/or <i>Fraxinus anomala</i>. Other associated shrubs include <i>Artemisia filifolia, Artemisia tridentata, Atriplex gardneri, Gutierrezia sarothrae, Lycium andersonii, Purshia stansburiana, Quercus havardii, Rhus trilobata, Sarcobatus vermiculatus</i>, and/or <i>Suaeda moquinii</i>. Herbaceous cover is sparse (<10% cover) with a variety of grasses and forbs; non-native annuals can be abundant. This group is known from eastern Washington, eastern Oregon, the Columbia Basin, and throughout the Great Basin. Elevations range from 500-2500 m. Stands occur along the banks or edges of, in or near temporary watercourses (aka washes, dry streambeds, gullies and the like). Surfaces occupied include sandy terraces, wash bottoms, point bars, as well as basin floors that are flat or gently sloping. Substrates are rapidly drained and coarse, such as sandy or gravelly soils derived from alluvium, gneiss, shale, cinder and sandstone, that are often very rocky as well.
