Red brome is an
introduced grass adapted to the warmer climates of Utah, found mostly
in the semi-desert summer precipitation of southern Utah where the
rainfall is 8 to 10 inches annually. It occurs at elevations from
2500 up to 5500 feet.
Soils: It grows in a wide range of
soils from shallow to deep and from fine to coarse textures. It
does well in limy soils and on hardpan soil.
species include blackbrush,
indigobush, sunflower, sand
dropseed, and spike dropseed.
brome is an important forage for cattle and desert tortoise in the
early spring. Generally, it is not considered a good forage plant
because of the short season of growth. It is a very poor erosion
control plant, and provides abundant fuel for wildfire. Red Brome
is an indicator of deteriorated range or disturbed sites.
Good management should strive to replace red brome with native range
plants high in desirability in terms of volume of production and,
more especially, in terms of wind and water erosion control.
