Relatively low fecundity may be responsible for lower Ruffed Grouse (Bonasa umbellus) populations in the southern Appalachians compared to those in more northern areas of the species ' range. Nutritional stress imposed by poor-quality habitat and greater nest predation have been cited as negative influences on reproduction in the region. We monitored 56 female grouse during the reproductive season in the Appalachian Mountains of North Carolina, 1999 - 2004, to measure reproductive success and evaluate cover used for nesting. Nests (n = 44) were located to determine fate and habitat...

Sound management of ruffed grouse (Bonasa umbellus) populations requires an understanding of survival and cause-specific mortality; however, these parameters have not been investigated at the southern extent of the species' range. Ruffed grouse were studied in the mountains of western North Carolina. Grouse (n = 276) were radiotagged and monitored >3 times/week. Mean annual survival was greater than reports from the northern core of the species' range. Seasonal survival was greatest in summer, followed by fall, winter, and spring. Of 155 mortalities, the greatest proportion was...
