Name: Nassella lepida Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This bunchgrass alliance of California's valleys and foothills grows on deep soils with a high clay content, often derived from sandstone or ultramafics. Stands can occur on all topographic positions, but due to climatic factors, they do not occur over 1700 m of elevation. The native California bunch grasses are adapted to a Mediterranean climate with moist, cool winters and long, dry summers. Precipitation varies from 25 and 70 cm per year, and falls mostly between November and April. This California native bunchgrass alliance is dominated by Nassella lepida. Other graminoids present may include Festuca californica, Melica californica, Nassella pulchra, Nassella cernua, Calamagrostis koelerioides, and Poa secunda. Many exotic annuals, such as Bromus hordeaceus, have invaded stands of this alliance. Emergent trees and shrubs may be present. Plant cover tends to be open. On sites with ultramafic-derived soils, serpentine-adapted species may be present.  Accession Code: VB.CC.19385.NASSELLALEPIDAH Plot-observations of this Community Concept: 0
