This type is mapped in broken landscapes associated with weathering of sedimentary
rocks where patches or layers of gyp are common in the landscape. Small (10 sq m to
200 sq m), open, sparsely vegetated patches or layers of gyp on slopes are common.
Short and mid-grasses such as sideoats grama, blue grama, hairy grama, little bluestem,
cane bluestem, sand dropseed, and annual bromes are also common. Forbs common

and western ragweed. Important shrubs may include skunkbush sumac, lotebush,
mesquite (within range), and Mohr shin oak. Succulents such as soapweed yucca,
pricklypear, and Christmas cactus may be present. Pinchot's juniper, or less commonly,
eastern redcedar may be present.
