Name: Festuca viridula - Carex hoodii Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This grassland association is known from northeastern Oregon, be may also occur in Washington, northern California and adjacent Idaho. <i>Festuca viridula</i> dominates high-elevation areas in the Wallowa Mountains of northeastern Oregon and the northern Cascade Mountains. On moist sites along ridgetops, seepy sideslopes and interforest meadows, <i>Festuca viridula</i> forms a unique community with <i>Carex hoodii</i>. These are tall, dense, productive montane grasslands. Stands are found from 1800 to 2410 m (5900-7900 feet) elevation, generally plateaus or ridgetops with slopes from 10-30%. Soils are formed from weathered basalt and are generally fairly shallow (76 cm) and stony. <i>Festuca viridula</i> dominates these grasslands with over 20% cover in fair condition stands, and even greater cover in good condition stands. <i>Carex hoodii</i> is codominant, ranging from 3-30% cover, and averaging 15%. Other graminoids include <i>Poa cusickii, Achnatherum occidentale (= Stipa occidentalis)</i>, and <i>Elymus elymoides</i>. Important forbs include <i>Eriogonum heracleoides, Lupinus argenteus var. laxiflorus (= Lupinus laxiflorus), Penstemon globosus, Microseris nutans</i>, and <i>Lupinus caudatus</i>. In early seral stands, <i>Achillea millefolium, Rudbeckia occidentalis</i>, and <i>Hackelia micrantha (= Hackelia jessicae)</i> can provide significant cover.
