Abstract : A wildlife species account for the ruffed grouse (Bonasa umbellus) is provided as Section 4.1.1 of the US Army Corps of Engineers Wildlife Resources Management Manual. The account is developed as a guide to provide the Corps District or project biologist with basic information on the biology, ecological requirements, and management technology for the ruffed grouse. Major topics covered include status, characters and measurements, population attributes, habitat requirements, management, and census and sampling. The importance of the ruffed grouse as a game species is discussed, and the present and historic range of the species is described. Diagnostic characters are presented, including criteria for sex and age determination. The section on population attributes includes details on densities, movements, breeding biology, and mortality factors. Food and cover requirements are treated from a regional perspective, and principal foods are listed by region in tabular form. Techniques for managing ruffed grouse habitat and estimating grouse populations are described, and major sources of information are provided. (Author)
