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 in the
Canyon: Gyp modern landscape include broom snakeweed, common broomweed, stiff greenthread, Navajo tea, Indian 67,378.6 0.372%
Grassland
breadroot, stemmy four-nerve daisy, sundrops species, 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.

This type is mapped on prairie soils across much of the state, and ranges from relatively dense woodlands to more
Ruderal Eastern open shrublands where eastern redcedar is a significant component. Common woody components vary by region,

black locust, western soapberry, lotebush, post oak, and Osage orange.

Crosstimbers: Post This type is mapped on slopes >20% and composition is similar to Crosstimbers: Post Oak Forest, although these
