Name: Nassella cernua Grassland
Reference: NatureServe Biotics 2019
Description: These grasslands are moderately widespread in California and occur across such a variety of environmental parameters that few generalities can be made. Sites range from sea level to 1400 m in elevation, and include all topographic locations. Climate is Mediterranean. Soils are usually fine-textured (clay is common), moist to saturated in winter, but very dry in the summer. Stands have a medium-tall graminoid layer from 0.5-1 m in height, dominated by the perennial, tussock-forming bunchgrass <i>Nassella cernua</i>. In some stands, this is the only perennial grass. Other perennial grasses that may be common include <i>Elymus glaucus, Festuca californica, Koeleria macrantha, Melica californica, Leymus triticoides, Poa secunda</i>, and <i>Aristida ternipes</i>. Cover of the bunchgrasses is described as open, but may be high in some stands. Perennial and annual forbs form a matrix between the bunchgrass tussocks; information on forb species composition is not available. Occasionally, emergent shrubs or other trees may be present.
