| Abstract |
|
Northern map turtles (Graptemys geographica) are large water turtles, which are abundant in the northeastern United States. Their range extends from southern Canada and east into Vermont, throughout the Great Lakes region and into lower Wisconsin. Although this turtle is widely distributed within this area, there were no reported occurrences in the Susquehanna River in New York until 2006. Upon further study, it was determined that a sizeable population of these turtles occurred along the Susquehanna River near Vestal, New York. The research presented in this paper is based on visual surveys to quantify occupancy of northern map turtles along 9.7 km of the river. Results indicate turtles occupy most of the surveyed stretch and that other populations likely exist in the larger tributaries of the Susquehanna as well. Capture-markrecapture data collected using basking traps (contributed by a collaborator) were used to determine population size. Analyses indicate approximately 123 individuals utilize the area around Moore Park in Vestal, NY. Although these turtles were not reported in the New York State herp atlas, other research does show their range extending into the Susquehanna River area of New York. This population could be a rediscovered or newly reported “old” population of northern map turtles.
