Family – Poaceae (Grasses)
Names can be confusing and/or location dependent!
Foxtail chess is an invader of the historical perennial grasslands of California.
Prefers disturbed sites
Prefers Mediterranean sites (dry summers, wet winters) but can occur in drier climates.
Prolific seed producer – averages 76 seeds/plant
Prefers disturbed areas
Requires less moisture than natives
Rarely grazed (little nutritional value, ripe seedheads/awns dangerous to livestock)
Very responsive to over-grazed and post-fire areas
Problem #2 - Fire
Red brome grows in areas that were once either open gaps (vacant niches) or filled with native annuals that were out competed.
Red brome interspersed with native plants
Native shrubs are killed = loss of habitat, food value and recreational/aesthetic values
Red brome now has more spaces to germinate
1966, B. rubens was common (21- 50%) only in the upper terraces, but occurred occasionally (6-20%) the shoreline and lower terraces of the NE side
2009, B. rubens was very common (50%+) to common on most of the island. It was not surveyed on the lower NE terraces due to pelican nests.
