Distribution of Ruffed Grouse Southeast of the Range of Quaking Aspen

We delineated the distribution of ruffed grouse (Bonasa umbellus) southeast of the range of quaking aspen (Populus tremuloides), and estimated the total range-area and forested range-area within this expanse. All or portions of 11 states comprised a total range-area of 285,184.3 km2, 25.7% of the total land-area ofthose states. The percentage of each state occupied by ruffed grouse varied from 99.4% in West Virginia to 2.5% in each of South Carolina and Alabama. Approximately 67% of the species' range was forested.
