Prairie in southern Michigan.

Prairies are systems dominated by native grasses and wildflowers. Savannas are prairies with scattered trees. They were once kept open by frequent fires which cleared out the underbrush and stimulated prairie plants. Over 99% of Michigan’s native prairies and savannas have been converted to agriculture or have grown up into forest in the absence of fire. Agricultural areas can be planted to native grasses and wildflowers. Degraded savannas can be selectively logged and rejuvenated with prescribed fire. In both situations, invasive exotic shrubs and plants must be managed. If you are interested in restoring habitat for prairie or savanna wildlife on your property, see the southeast and southwest Lower Peninsula LIP pages for more information.
