CEGL001460 Artemisia cana (ssp. bolanderi, ssp. viscidula) / Leymus cinereus Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (Bolander Silver Sagebrush, Mountain Silver Sagebrush) / Basin Wildrye Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs in a semi-arid region of varied topography. Average annual precipitation is between 20-40 cm, with somewhat more at the higher elevations. Occurs in perennially moist, semi-alkaline, pluvial lakebeds above 1070 m (3500 feet) or montane meadows to 1980 m (6500 feet). Only a few forb species occur, typically in moist microsites. These include species of Astragalus, Orthocarpus and Rorippa. Bare ground is extensive. Artemisia cana and Leymus cinereus are diagnostic species. The 1- to 2-m tall Artemisia cana is moderately to widely spaced in the canopy. The herbaceous layer is dominated by the widely spaced 2-m tall bunchgrass Leymus cinereus.

Floristics: Little information is available on the composition of this association. The 1- to 2-m tall, broad-leaved evergreen shrub Artemisia cana is moderately to widely spaced in the canopy of this association. The herbaceous layer is dominated by the widely spaced, 1- to 2-m tall bunchgrass Leymus cinereus, which often forms clumps up to 1 m broad. Only a few forb species occur, typically in moist microsites. These include species of Astragalus, Orthocarpus, and Rorippa. Bare ground is extensive.

Environmental Description: The association occurs in a semi-arid region of varied topography. Average annual precipitation is between 20-40 cm for much of the region, with somewhat higher amounts at higher elevations. This association is found on moist, semi-alkaline flats or valley bottoms within the sagebrush or western juniper zones of Oregon. Elevations of these bottomlands can range from 1060 to over 1830 m, but at higher elevations the association occurs as small patches in montane meadows. Soils are alkaline, and typically deep, with some movement of water through the soil layers.
Geographic Range: This plant association is found in Oregon''s Blue and Ochoco mountains and Lake, Harney, Malheur and Klamath counties, extending south into the northeastern California counties of Modoc and Lassen.
