Red Brome Grass
Photographed at Mesquite Wash, Maricopa Co., Arizona. March 29, 2008.
ANNUAL: Annual weedy grass of spring growing in abundance after winters
with moderate to high rainfall amounts. Typically less than
½ meter tall.
This invasive weed not only competes with native herbs and grasses, it also promotes range fires in the Sonoran Desert where most plants are not fire-adapted. The disruption to the natural ecosystem cannot be understated. Originally introduced as a range grass, now even ranchers find it a nuisance because the barbed spikelets cause injury to the gums of cattle.
