Name: Bromus (diandrus, hordeaceus, madritensis) Ruderal Grassland
Reference: NatureServe Biotics 2019
Description: 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 <i>Bromus diandrus, Bromus hordeaceus, Bromus sterilis</i>, and <i>Aira caryophyllea</i>. Other species present include <i>Hypochaeris radicata</i> and <i>Pteridium aquilinum</i>. This dry ruderal grassland typically has gone to seed and vegetation begins to dry by early summer.
