CEGL003018 Bromus (diandrus, hordeaceus, madritensis) Ruderal Grassland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: (Ripgut Brome, Soft Brome, Compact Brome) Ruderal Grassland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is currently described from San Juan Island National Historical Park, Washington. It is also known to occur in California. Additional global information will be added when available. This type occurs on dry sites as a result of shallow or sandy, coarse-textured soils and/or south-facing aspects. Most occurrences are exposed to drying winds that appear to desiccate the sites by early summer. These sites have been previously disturbed by grazing and/or historical plowing. Vegetation composition is primarily composed of non-native annual species such as Bromus diandrus, Bromus hordeaceus, Bromus sterilis, and Aira caryophyllea. Other species present include Hypochaeris radicata and Pteridium aquilinum. This dry ruderal grassland typically has gone to seed and vegetation begins to dry by early summer.
