The most valuable range grasses are by all odds the various species of grama. These abound as a ground cover over most of the region whether valley or hill or mountain slope, and in normal years furnish an abundant range; but during periods of drought overgrazing is heavy.

Wild flowers show a periodicity in season induced by the semi-desert climate. Sorts which in a more moist region bloom in spring, here bloom whenever they can get the necessary moisture. This usually means they wait till mid-summer or early fall. Then, with plenty of rain, they cover all protected areas with a profusion of infinitely varied color. Showy species of four o'clocks, milkweeds, Asters, Senecios, milkworts, mallows, lupines, Astragalus, prairie clover, and many others are abundant.
