During the past 20 years sharp-tailed grouse (Pedioecetes phasianellus) and pinnated grouse (Tympanuchus cupido) have steadily declined in Wisconsin as a result of changing land-use patterns. On the other hand, ruffed grouse (Bonasa umbellus) in Wisconsin have increased since the middle thirties, and at present are one of the major game birds in this state. This population increase coincides with the regrowth of forests following the fires and logging that occurred in the period 1900-1938. To determine how to maintain these favorable environmental conditions, basic research on the habitat requirements of ruffed grouse was needed. This information could then be integrated with forest management and silvicultural practices. Since the grouse habitat work of Bump, Darrow, Edminster and Crissey (1947) in New York and Hungerford (1953) in Idaho was done in forest types quite different from those in the Lake States, it was felt that a reappraisal of their results was needed before a management program could be initiated in Wisconsin.
