North Carolina’s marsh rice rat reports come almost entirely from the Coastal Plain, in the tidal marshes and pocosin wetlands that fringe the Albemarle and Pamlico sounds. It’s a swimmer built for flooded grass, not the Piedmont hardwoods or Blue Ridge forest that hold most of the state’s other small rodents.
It swims through standing marsh water on regular routes, feeding on seeds, plants, insects, and small aquatic animals, and builds its nest just above the waterline where flooding won’t reach it. That tight link to wet, grassy ground explains why records track sound-side marsh and pocosin bog rather than dry upland habitat.
North Carolina’s records are thin, which likely reflects how easily this species goes undetected in dense marsh vegetation rather than genuine scarcity. Wetland drainage and rising seas along the coast remove exactly the cover this rat depends on.
