Occurrence

Widely scattered and locally abundant through much of the desert grassland from about 2,500 to 5,700 feet. Has been found in Coconino, Yavapai, Greenlee, Gila, Pinal, Cochise, Pima and Santa Cruz counties.

Forage Value

Highly palatable, and for this reason, rather inclined to be overgrazed even when associated grasses are properly utilized. Because of the general softness and thinness of the leaves, and the tendency for some green leaves to be present much of the year, Hall’s panic grass remains moderately to highly palatable even after plants have cured.


Grazing Management

Because it usually makes up a minor portion of the perennial grasses on any range, few ranges can be managed to maintain this grass. It is quite palatable and may be damaged by a degree of grazing that does not harm the associated grasses.
