Eastern Box Turtle (Terrapene carolina carolina) home range size and habitat preferences were studied over a 9 year period at the Jug Bay Wetlands Sanctuary, Maryland. The analyses made use of data from both mark-recapture and telemetry, and three different methods were used for home range analysis: minimum convex polygon (MCP), bivariate normal (BN), and 90% kernel (K). Only turtles with 5 or more sightings were used for home range determinations, with an average of 26 sightings for females (n = 49), 15 for males (n = 47), and 22 for juveniles (n = 4). Home range sizes were affected weakly if at all by the number of sightings. All analyses yielded significantly larger home ranges for females: for all data and methods combined (mean ± S.D.), 12.9 ± 19.4 ha for females, 5.3 ± 10.2 ha for males (p < 0.05). The results were more distinct for telemetry records than for random recaptures. Overall females used more of each of the available habitat types. Both males and females were found at higher frequency in each of the habitats, excluding tidal wetland, than expected based on habitat availability. Females used mostly the Phragmites, scrub shrub, and meadow habitats; males used mostly the open forests, flood plains, dense forests, and meadows; and juveniles used more of the meadow and tidal wetland habitats than either adult females or males. The size and diversity of female home ranges has important conservational implications because, without recognition of this variation, critical nesting habitats are likely to be overlooked.
