Range size and dynamics of black bears (Ursus americanus) were determined in Great Dismal Swamp (GDS), an 850-km2 forested wetland straddling the eastern border of Virginia and North Carolina. Male ranges were larger (P < 0.05) than female ranges annually and seasonally. Median range sizes were 21.4 km2 for adult females (N = 11),33.1 km2 for subadult females (N = 7), and 79.0 km2 for males (N = 10). Extensive fall movements inflated female ranges. Range shifts were maximal from late summer to early fall and early fall to late fall, averaging 4.4 ± 0.7 km (N = 14) and 4.4 ± 0.8 km (N =...

Food habits were determined for a black bear (Ursus americanus) population in Great Dismal Swamp on the Atlantic Coastal Plain. A total of 535 scats was collected from May 1984 to August 1986. Seasonal shifts in diet composition were similar to previously reported findings for black bear food habits in the southeastern United States. Diets changed from succulent, herbaceous material in the spring to soft mast and corn in the summer. Early fall diets were largely black gum (Nyssa sylvatica) (33%) and oak (Quercus spp.) (32%) mast. Late fall and winter diets were dominated by fruits of...
