|
Terrapene carolina carolina (Eastern Box Turtle) home range size and habitat preferences were studied over a 9 year period at the Jug Bay Wetlands Sanctuary in Maryland. Males were found to have a mean home range of 1.51 ± SD 1.33 Ha; while females have a significantly larger (t(20)=2.589, p=0.018) home range of 5.92 ± SD 7.49 Ha. The home range estimates based on two commonly used data-collection methods, mark-recapture and telemetry, were also compared to determine which was more accurate when compared to the overall home range (based on compiled data from the 2 methods). Telemetry females and males were found to have significantly different home ranges (t(16)=2.234, p=0.040), and the difference between female random and compiled data was also found to be significant (t(21)=-2.465, p=0.022). To increase confidence levels in the home range size study turtles were chosen from the database based on 10+ sightings (29 on average). Females were found to use all 7 habitat types with no significant preference, and males were found to use most of the habitats with similar frequency to the females although they did use the meadow appreciably less and were never found in the Phragmites. The significant size and diversity of female home ranges has important implications, because without their recognition critical nesting habitats are likely to be left overlooked by conservation plans putting T. c. carolina populations at risk.
