Ruffed grouse natality, chick survival, and brood micro-habitat selection in the southern Appalachians
… Appalachian Cooperative Grouse Research Project (ACGRP). Nesting rate, pooled over all regions, was 83.6% in 1997 and 79.7% in 1998. In the 2-year period, the Alleghany Plateau reported the highest nesting rate (97.6%) while the Ohio River Valley reported the lowest rate (54.2%). Overall hen …

Population ecology of and the effects of hunting on ruffed grouse (Bonasa umbellus) in the southern and central Appalachians
… Appalachian Cooperative Grouse Research Project (ACGRP). Several hypotheses have been offered to explain the low abundance of ruffed grouse in the region including inadequate quantity of early-successional forests due to changes in land use, additive harvest mortality, low productivity and …

Ruffed grouse (Bonasa umbellus) habitat ecology in the central and southern Appalachians
… Appalachian Cooperative Grouse Research Project (ACGRP) researchers tracked >1500 radioed grouse at 10 study sites (1996__2002). To improve our understanding of Appalachian grouse habitat ecology, I carried out two primary analyses of this database. First, grouse should be under selective pressure …

Factors Influencing Predation on Ruffed Grouse in the Appalachians
Predation accounts for the majority of ruffed grouse mortality beyond the brooding period throughout grouse range. Most studies of ruffed grouse ecology have taken place in the central portion of the species range including the Great Lakes states and southern Canada where aspen (Populus …
