Federal & State Threatened (DNR herp checklist); RTE list Dec 2025: G2G3 S2, State Threatened, Federal Threatened
What the sources say
Range: Found in small portions of Maryland north-central counties, from Cecil to Carroll. This species is Federally Threatened due to threats by collectors and habitat loss. If you see one, please report sightings to Maryland Wildlife and Heritage Service.
Habitat: As its name implies, this turtle prefers spring-fed wetlands with soft highly organic soils. They like relatively open habitats with slow flowing stream systems or surface seepages. They are burrowers and need a soft substrate for digging. Dominant vegetation is usually grasses and sedges. (DNR)
Habitat: A terrestrial species, commonly encountered in rich, open woodlands and riparian forests, but may also be found in pastures and wet meadows, and during hot weather may be found soaking in shallow waters and mucks of various wetland types or under leaf litter. (DNR)
Primarily found on the Coastal Plain but has been found on the Piedmont as far west as Washington County. DNR
What the sources say
Habitat: Prefers slow-moving shallow water with soft bottoms and thick emergent and aquatic vegetation, such as ditches, wet meadows, small ponds, marshes, cypress swamps and Delmarva Bays. This species is very tolerant of brackish water, so may be locally abundant along tidal marsh edges, upland marsh hummocks and offshore islands. (DNR)
Can be found throughout Maryland but more common on the Coastal Plain. DNR
