Name: Deschampsia cespitosa - Horkelia marinensis Marsh
Reference: NatureServe Biotics 2019
Description: This association is only known from the Point Reyes National Seashore, California. 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 an intermittent to continuous herb layer of up to 25% mosses and lichens, 40-50% cover at 0-25 cm and 7-15% at 25-50 cm tall. This association is dominated by <i>Deschampsia cespitosa</i>. <i>Horkelia marinensis</i> is usually from 1-18% cover. Other species are characteristic of coastal dunes and include <i>Cardionema ramosissimum, Armeria maritima, Gamochaeta purpurea, Vulpia bromoides</i> (exotic), <i>Carpobrotus edulis</i> (exotic), and <i>Holcus lanatus</i> (exotic).
