 SPOTTED TURTLE RADIO TELEMETRY
Residential Subdivision in Rare Turtle Habitat

Oxbow conducted a radio-telemetry study over multiple years on a small population of spotted turtles to determine the effectiveness of turtle barriers and a turtle passageway beneath a subdivision road to avoid turtle mortality due to traffic while allowing seasonal movement patterns. After 5 seasons of monitoring, Oxbow determined that the passageway beneath the subdivision road was adequately sized so that turtles crossed beneath the road on a regular basis. However, some of the turtle barrier types were not adequate to prevent turtles from crossing from the protected area to the subdivision side of the project. Although, no turtles were killed during our monitoring period, Oxbow recommended improved turtle barrier types and periodic monitoring of the barriers to ensure they are effective. This information was valuable for both Oxbow and the Natural Heritage and Endangered Species Program so that better designs can be incorporated in future projects.
