Range: Northeast United States, Southern Appalachian region.
Habitat Type: Open canopy wetlands with little standing water, bogs, fens and murky soils.
Primary Diet: Small insects, invertebrates, various plant vegetation.

States with Current Habitat
bog turtle states
Bog turtles are one of the most rare turtles found in the United States. Laws banning the collection of the turtles for sale have done little to stop the practice with bog turtles being a prized species in many animal black markets.
Invasive plants such as the purple loosestrife can dry out large areas of suitable habitat. Purple loosestrife grows in large, compact clumps that are impenetrable to the turtle, restricting its movement.
Bog turtle populations are divided into two distinct populations separated by a 250-mile distance. The northern populations found in Connecticut, Massachusetts, New York, Pennsylvania, New Jersey, Delaware, and Maryland are listed as threatened. The southern populations found in Georgia, North Carolina, South Carolina, Tennessee, and Virginia are listed as threatened due to similarity of appearance.
Threats related to Global Warming
Bog turtles are extremely sensitive to the effects of global warming. The turtle’s survival is closely tied to its delicate habitat. Erratic weather patterns resulting from global warming will disrupt the fragile balance key to the turtle’s survival. By altering hydrological cycles, global warming will either dry out or flood the turtle’s habitat.
In addition to bog turtles needing a very specific habitat, much of the remaining habitat in the Northeast has been fragmented apart by roads and development. As the changing climate alters the availability of the turtle’s current habitat, they will have very limited ability to migrate to places that could be more suitable.

Sea turtles swim in tanks in the rehab center at the North Carolina Aquarium in Mateo, N.C., on Tuesday, January 5, 2010. Volunteers and staff have taken in an unprecedented number of cold-stunned sea turtles this year that have beached due to exceptionally low temperatures this winter. The Network for Endangered Sea Turtles, NEST, covers the medical costs for the animals and is seeking donations to help them through this winter season. (Preston Gannaway | The Virginian-Pilot)
