Northern Prairie Wildlife Research Center
Results of a 5-year study on effects of four treatments (spring burn, fall burn, mowing, and grazing) on native tallgrass prairie in northwestern Minnesota. Treatment effects on litter, upland grasses and forbs, shoreline vegetation, songbirds, small mammals, and insects summarized. Effects on willow and aspen invasion are treated in detail. Effects are related to known habitat requirements of ducks and prairie chickens in effort to develop a basic program for tallgrass prairie maintenance. See also Tester and Marshall, 1961.
