Common names: red brome; foxtail chess

Bromus madritensis ssp. rubens (=B. rubens) (red brome) is a cool-season annual grass (family Poaceae) found throughout California, especially in the southern part of the state. Red brome invades disturbed areas, roadsides, agricultural fields, rangelands, and forestry sites, in addition to native communities. Red brome is spreading rapidly in desert shrublands, pinyon pine-juniper communities, three-needle pine woodlands, and coastal scrub, where it increases fire frequency and converts habitat to annual grassland.
