Abstract: The Eastern box turtle (Terrapene carolina carolina) is a vulnerable species with decreas-
ing population density from anthropogenic development and habitat loss. To determine the im-
pact of electric utility pole replacement and vegetation maintenance on the home range size and
habitat preference of T. carolina carolina, we radio-tagged 13 box turtles and located them weekly
from April to November 2019, recording several habitat measurements at each location. We per-
formed a principal component analysis of vegetation data and estimated home range size using
95% minimum convex polygon (MCP), kernel, and Brownian-bridge methods. Our data indicate
that turtles prefer shrub cover and avoid rocky areas. While there was no signifcant diference
between male and female home range size, a post hoc analysis dividing females into right-of-
way (ROW) and non-ROW groups revealed a signifcant diference in female home range size,
which may result from accessibility of higher-quality nesting sites within the ROW compared with
surrounding forest stands.

INTRODUCTION
The woodland box turtle, also commonly referred to as the Eastern box turtle
