CEGL001551 Artemisia cana (ssp. bolanderi, ssp. viscidula) / Poa fendleriana ssp. fendleriana Shrub Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (Bolander Silver Sagebrush, Mountain Silver Sagebrush) / Muttongrass Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This community occurs on broad, low-gradient floodplains at moderate to high elevations where it occurs on dry terraces and inactive floodplains and on the dry margins of mid-elevation meadows. Elevations range from 1340 to 1710 m (4400-5600 feet) and as high as 2135 m (7000 feet) in the Warner Mountains. Soils are deep, easily eroded alluvium with surface textures of fine sandy to silty clay loams. Available water-holding capacity is moderately high. Water tables are within 60 cm (2 feet) of the soil surface in May and June, dropping to 1.2-1.7 m (4-5.5 feet) below the soil surface in July through September. Artemisia cana is the dominant shrub. Artemisia tridentata (usually ssp. vaseyana but occasionally ssp. tridentata) is also common in some sites. Poa fendleriana is the dominant herbaceous species. Other common herbaceous species include Koeleria macrantha, Elymus trachycaulus, Muhlenbergia richardsonis, Achnatherum occidentale ssp. occidentale, Carex praegracilis, Achillea millefolium, Symphyotrichum campestre var. bloomeri, and Cirsium foliosum.

Geographic Range: This association is scattered across its range in south-central Oregon, in the East Cascades ecoregion, and in the Ochoco and Blue mountains in the Idaho Batholith ecoregion. It may possibly extend south into the Modoc Plateau of California. The association is scattered in occurrence because it requires broad, low-gradient floodplains or dry margins of mid-elevation meadows.
