CEGL003325 Deschampsia cespitosa - Danthonia californica Coastal Marsh

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Tufted Hairgrass - California Oatgrass Coastal Marsh

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is only known from the Point Reyes National Seashore. Information about its global characteristics is not available without additional inventory. It was likely to be more widespread along the coast from Santa Cruz County, California, north to Washington, prior to the introduction of invasive exotic annual and perennial grasses. Other similar stands at Salt Point State Park occur adjacent to the coastal bluffs as a rim of native grassland adjacent to non-native annual and perennial grassland. Stands of this grassland association form a continuous herb layer. There is usually less than 20% cover between 0.5 and 1 m tall. It is dominated by Deschampsia cespitosa and Danthonia californica. Aira caryophyllea, Plantago lanceolata, Lolium perenne, Rumex acetosella and Nassella pulchra may also be present.

Small stands resembling this association have been inventoried at Salt Point State Park in Sonoma County (CNDDB 1993).
