| Abstract |
|
A landscape-scale approach to species conservation is important for species in which land cover use varies both temporally and spatially. We used radio-telemetry to study habitat use and movement patterns of adult female Blanding’s Turtles (Emydoidea blandingii) in the context of landscape composition, connectivity, and physiognomy over two years to inform management activities for the population. Throughout the year, Blanding’s Turtles used a complex of wetlands differing in size and depth. Turtles traveled overland extensively during the nesting season, and exhibited frequent use of ephemeral wetlands while on nesting forays. In addition, they made numerous road crossings and many turtles nested along road edges, indicating that paved roads did not represent a barrier to nesting-related travel, and may represent an ecological trap to this population. By taking a landscape-level approach to studying habitat use and movement patterns, we demonstrated how this species used both aquatic and terrestrial cover types throughout the year, the distances traveled between different cover types during different seasons, and how connectivity between habitat patches may affect adult survival. We recommend that conservation efforts for Blanding’s Turtle populations be implemented at the landscape level and: (1) encompass all land cover types used throughout the year; (2) maintain corridors for safe travel among these cover types; and (3) include sufficiently-large terrestrial buffer zones around wetlands such that the entire extent of females’ nesting-related travel is enclosed.
