Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Deergrass Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous bunchgrass association has been documented in southern and central California and in the lower Sierra Nevada foothills. It occurs on gently rolling slopes (1-3%) or flat areas between 90 and 1496 m (296-4909 feet) elevation. Soils are well-drained sandy to sandy loams. Stands form open to dense grasslands dominated by Muhlenbergia rigens. Other graminoids present include Bromus diandrus, Bromus hordeaceus, Elymus glaucus, Leymus triticoides, and Lolium perenne ssp. multiflorum. Forbs are also often present and include Clarkia purpurea ssp. quadrivulnera, Erodium cicutarium, Eschscholzia californica, and Hypochaeris glabra. Shrubs may also be present with <10% cover, including Eriogonum fasciculatum, Eriogonum wrightii, Rubus armeniacus, and Toxicodendron diversilobum.

Floristics: Stands form open to dense grasslands dominated by Muhlenbergia rigens. Other graminoids present (many exotic) include Bromus diandrus, Bromus hordeaceus, Elymus glaucus, Leymus triticoides, and Lolium perenne ssp. multiflorum (= Lolium multiflorum). Forbs are also often present and include Clarkia purpurea ssp. quadrivulnera, Erodium cicutarium, Eschscholzia californica, and Hypochaeris glabra. Shrubs may also be present with <10% cover, including Eriogonum fasciculatum, Eriogonum wrightii, Rubus armeniacus (= Rubus discolor), and Toxicodendron diversilobum.
Dynamics: Stands can withstand periodic flooding and occur in settings with periodic disturbance. Burning increases the vigor of stands, as seedlings and new growth can be stimulated, detritus can be cleared away, and nutrients can be recycled.
Environmental Description: It occurs on gently rolling slopes (1-3%) or flat areas between 90 and 1496 m (296-4909 feet) elevation. Soils are well-drained sandy to sandy loams.
Geographic Range: This grassland is known from the Coast Ranges of central and southern California and from the Sierra Nevada foothills.
