Uses/Management
Wildlife	Used by livestock throughout the summer. Does not cure well, considered only fair forage for fall and winter grazing. Highly palatable in the summer but only fairly palatable after maturity. Provides a good source of protein and vitamin A throughout the summer when leaves are green. Digestibility and crude protein decrease as plants mature. Spring burning (April 1-15) increased digestibility. Intolerant of repeated close grazing; decreaser on all range sites. May decrease during drought, but recovers rapidly when precipitation returns to normal. Cutting Indiangrass at the hay stage has showed a decrease in plant density, but cutting at monthly intervals during the summer caused little or no decrease.
Grazing	Highly palatable; good source of protein and Vitamin A for wildlife in the summer when plants are actively growing. Fair forage in fall and winter once the plant matures. Excellent protective and nesting cover for pheasants, northern bobwhite, mourning doves, prairie chickens, and several songbirds.
