Summary
Seven annual surveys have been conducted during varying portions of a 19-year period (1962-80) which permit assessments of them as relative abundance indexes of ruffed grouse (Bonasa umbellus) in Wisconsin. These surveys included the harvest estimate, roadside drumming count transects, winter roost counts, study area censuses of male grouse on areas in northern and central Wisconsin, a spring and a summer rural resident wildlife inquiry, and a grouse brood tally. These have been extensively applied rather than narrowly used except for the study areas.
