CEGL001595 Carex hoodii - Festuca idahoensis Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Hood''s Sedge - Idaho Fescue Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association occurs in eastern Oregon, Washington and Idaho on high-elevation ridges of the Wallowa and Seven Devil mountains of the Blue Mountains ecoregional section. Sites range from gentle, broad, dissected plateau ridgetops to steep mountain sideslopes at 1830-2410 m (6000-7900 feet) elevation. Soils are moderately deep to deep silt loam. Stands are typically dense with high and diverse cover of sedges, grasses, and perennial forbs. Abundant Festuca idahoensis and Danthonia intermedia occur with a variety of different sedge and grass species, including Carex hoodii, Carex geyeri, Achnatherum occidentale, and Koeleria macrantha. Commonly associated forbs are Lupinus argenteus var. laxiflorus, Geum triflorum, Hieracium scouleri var. albertinum, Antennaria rosea, Arenaria congesta, and Symphyotrichum foliaceum. This association should not be mistaken as ~Festuca idahoensis - Carex hoodii Grassland (CEGL001609)$$, which is abundant in the Blue Mountains ecoregional section. Carex hoodii - Festuca idahoensis is distinguished from Festuca idahoensis - Carex hoodii on the basis of the presence of Danthonia intermedia, Arenaria congesta, or Antennaria rosea.
