Characteristics of Black Bear Dens in the Southern Appalachian Region

Characteristics of Black Bear Dens in the Southern Appalachian Region

Dens of radio-instrumented black bears (Ursus americanus) were examined in the southern Appalachian Mountains from 1973 to 1982. Most dens were in tree cavities high above ground. Entrance height differed among tree species with high entrances in yellow poplars (Liriodendron tulipifera) and low entrances in chestnut oak (Quercus prinus), red maple (Acer rubrum), and yellow birch (Betula alleghaniensis). Den tree species differed with elevation, macrotopography, and microtopography. Both tree dens and ground dens were characterized by high microtopographic position. Chestnut oaks and northern red oaks (Q. rubra) comprised 10 of 15 tree dens in the exterior of the study area. Extensive use of these 2 species indicates the importance of incorporating site provisions into timber management plans in the Southern Appalachian Region.
