Name: Carex nardina Herbaceous Alliance
Reference: Western Ecology Working Group of...
Description: Plant associations within this short grassland alliance occur on windy, exposed ridges in subalpine and alpine regions. Elevations range from 2200-2600 m in the Cascade Range and 3000-3900 m in Colorado. Sites are typically gently sloping (2-25%), sparsely vegetated, stabilized scree slopes. Winter snow cover is thin, due to the exposed slopes, thus snowmelt is relatively early (late April to early May). Soils are rocky and shallow with high pH value, 5.5-7.1. Carex nardina is calciphilous throughout its range, and it dominates the graminoid stratum. In the Colorado stands, Festuca brachyphylla, Poa lettermanii, and Festuca minutiflora are associates in the graminoid stratum. Besseya alpina is typically a codominant in the forb layer. Other forbs in the Colorado stands include Erigeron grandiflorus, Silene acaulis, Packera werneriifolia (= Senecio werneriifolius), and Chionophila jamesii. The fern layer is dominated by Selaginella densa. The moss layer is well-developed with Cladonia pyxidata, Hypnum revolutum, and Polytrichum piliferum. Common associates in the Cascade Range stands include Festuca ovina, Minuartia obtusiloba (= Arenaria obtusiloba), and Smelowskia ovalis. Important cryptograms are Tortula ruralis, Thamnolia subuliformis, and Cornicularia aculeata. Information on adjacent communities is not available.
