Common (Translated Scientific) Name: Pacific Reedgrass / Coyotebrush Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous association is reported from Washington, Oregon and California. The following description is based on occurrences at Point Reyes National Seashore in California. Additional information will be added as it becomes available. This association occurs on gentle to moderate slopes (9-28°). It is found from midslope to ridge positions with northern to eastern exposures. Stands are located within 5 km of the Pacific Ocean. Stands are frequently small, less than 2 acres in size, and occur on mesic northward slopes from the top to middle third of slopes. These slopes are frequently fog-shrouded in the summer months and exposed to strong winds. This type includes stands dominated by Calamagrostis nutkaensis with cover between 30-70%. Baccharis pilularis is also present with cover values from 7-15%. The canopy is fullest between 50-100 cm, with emergent flowering stems of Calamagrostis to 2 m. Baccharis pilularis is typically stunted and less than 1 m tall. Thus the grass layer is as tall or taller than the sparse shrubs. Common associates include Pteridium aquilinum, Holcus lanatus (exotic), Plantago lanceolata (exotic), Rubus ursinus, and Iris douglasiana.
