Pennsylvania: Climate Change Brings Uncertain Future for Bog Turtle

In October 2010, the U.S. Fish and Wildlife Service established the Cherry Valley National Wildlife Refuge in northeastern Pennsylvania, in part, to protect the federally threatened bog turtle. Climate change, however, could amplify existing threats to the turtle’s fragile habitat. 

The Pennsylvania Fish and Boat Commission, Pennsylvania Natural Heritage Program, and the Pennsylvania Department of Conservation and Natural Resources all have identified habitat loss and fragmentation -- mostly due to development -- as the main threat facing bog turtles.

When the Refuge boundary was established, Cherry Valley was experiencing a surge in residential development that threatened the turtle’s habitat -- wet meadows and other shallow, sunny wetlands. In a November 2010 article in Refuge Update detailing establishment of the refuge, Refuge Manager Michael Horne said the first parcel acquired for Cherry Valley National Wildlife Refuge’s provided “promising wetlands in terms of bog turtle management.”
