Muhlenbergia sylvatica grows in upland forests, along creeks and hollows, on rocky ledges derived from sandstone, shale, or calcareous parent materials, moist prairies, and swamps, at elevations from 30-1500 m. It is restricted to the Flora region, its primary range being southeastern Canada and the midwestern and eastern United States. Reports from British Columbia were based on a misidentification (Douglas et al. 2002). The record from Arizona is based on the report in Kearney and Peebles (1951) of a collection made by Toumey at Grapevine Creek in the Grand Canyon.
