Usually associated with deep-water areas of coastal plain rivers and associated floodplain marshes, and ponds. Typically found in areas with a soft silt bottom, lots of aquatic vegetation and numerous basking sites, such as logs and debris. Can also be found in brackish water, near river mouths.
How to Find:
Look for basking turtles from March to November along the shorelines of large Eastern Shore rivers. This species is shy and difficult to approach, so it is best to view from afar with binoculars.
Canoe or kayak in quietly for a close-up view.
Distribution in Maryland:
Primarily a Coastal Plain species but can be found as far west as Allegany County.
