Name: Carex hoodii Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This medium-tall, bunch, temperate or subpolar grassland alliance is confined to the highest elevations occupied by canyon grasslands, between 1950 and 2400 m. It occurs commonly in the openings wholly or partially surrounded by forests. It occurs with gentle topography; slope between 4-6%. The soils are shallow and stony and have high organic matter content. Soil texture varies from loam to sandy loam with a soil pH average of 5.0 in the A horizon. Only one plant association, Carex hoodii - Festuca idahoensis Herbaceous Vegetation (CEGL001595), is described for this alliance. Carex hoodii dominates the sedges, but typically Carex geyeri, Carex multicostata, and Carex rossii can occur in the graminoid layer. The other dominant, Festuca idahoensis, always occurs with Carex hoodii. Perennial forbs are also abundant (25-60% cover). They include Antennaria anaphaloides, Antennaria microphylla, Arenaria congesta, Symphyotrichum foliaceum (= Aster foliaceus), Eriogonum flavum, and Potentilla glandulosa. Deciduous forests, dominated by Populus tremuloides, frequently occur in the adjacent uplands.  Accession Code: VB.CC.20001.CAREXHOODIIHERB Plot-observations of this Community Concept: 0
