Name: Carex nardina Scree Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This association occupies windy, rocky, high-alpine slopes that are free of snow by early May. Slopes range from moderate to steep, and elevations vary depending on the location. In Washington, stands occur at around 2100 m (6900 feet); in Wyoming, the documented stand is at 3254 m (10,676 feet), and the stands in Colorado are located around 3800 m (12,467 feet). Soils are well-drained and gravelly with high rock cover. Total vegetation cover is around 40%. The community is strongly dominated by the tufted sedge <i>Carex nardina</i>. Other graminoids present include <i>Calamagrostis purpurascens, Festuca brachyphylla</i>, and <i>Carex albonigra</i>. The forb element is variable depending on location; in the northwestern part of the range (Washington), <i>Minuartia obtusiloba</i> and <i>Smelowskia ovalis</i> are the most common associated species. In the middle part of the range (Wyoming), <i>Silene acaulis, Astragalus kentrophyta</i>, and <i>Phlox pulvinata</i> are common. In Colorado, <i>Silene acaulis, Erigeron grandiflorus</i>, and <i>Besseya alpina</i> are the most constant species. The moss layer is often high in cover and diversity.
