Habitat selection, where observed use of a resource is disproportionate to availability, is an important behavior allowing individuals to position themselves spatially relative to critical resources in heterogeneous environments. For species that experience variable environments across broad geographic ranges, we expect resource selection templates to vary among populations accordingly. Using radiotelemetry, we examined habitat selection for populations of Eastern Box Turtles, Terrapene carolina, in fire-maintained forests of the sandhills compared to nearby unburned coastal plain forests in south-central North Carolina. Turtles at the fire-maintained sandhills site preferred bottomland habitats and areas near steams, whereas turtles in the unburned coastal plain environment preferred uplands and used streams randomly. In addition, turtles in the fire-maintained sandhills avoided Longleaf Pine and more strongly preferred hardwood and non-Longleaf Pine forests compared to turtles at the unburned coastal plain site. Body size, but not sex, was also an important source of variation in habitat selection within populations, with smaller turtles more strongly preferring areas near water. Selection of habitat structural components in the immediate area of locations did not differ between sites, sexes, or body sizes. These results highlight the variety of resource selection templates in T. carolina, underscoring a potential need for population- or region-specific conservation and management strategies.
