Name: Nassella lepida Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: These grasslands are moderately widespread in California and occur across such a variety of environmental param that few generalities can be made. Sites range from sea level to 1700 m in elevation, and include all topographic locations. Climate is Mediterranean with mean annual precipitation ranging from about 12 cm in the southwestern San Joaquin Valley to 200 cm in the montane of northwestern California. Soils are often deep clays derived from sandstone or ultramafic substrates. They are moist to saturated in the winter, but are always dry during the summer. Stands have a medium-tall graminoid layer from 0.5-1 m in height that is dominated by the perennial, tussock-forming bunchgrass Nassella lepida. In some stands, this is the only perennial grass. Other perennial grasses that may be common include Festuca californica, Melica californica, Poa secunda, Nassella pulchra, Nassella cernua, and Calamagrostis koelerioides. Cover of the bunch grasses is described as typically low, but quantitative information is not available. Emergent shrubs and trees may be present. Stands that occur on ultramafic parent materials will have additional, serpentine-adapted species.
