Like the marsh rabbit it often shares ground with, the marsh rice rat is a true Coastal Plain wetland species in Georgia, not a mountain or Piedmont animal. Most of the state’s records come from the Okefenokee Swamp’s flooded prairies and the salt marshes fringing Cumberland Island, the two habitats where the wet, grassy cover this rodent depends on is thickest and most reliable.
This rat is one of the few rodents in Georgia genuinely built for a semi-aquatic life. It swims well and dives readily to escape a predator, and it often builds a small woven nest of grass just above the waterline rather than a burrow, keeping it dry through the tidal swings and seasonal flooding common in both the Okefenokee and the coastal marshes. Its diet leans on marsh vegetation, seeds, and small invertebrates picked from the wet ground it rarely leaves.
Records here run year-round, though with only a handful of confirmed observations relative to how much suitable wetland exists across the Coastal Plain, and NatureServe ranks the species S5, Secure, in Georgia. The gap between how little has been documented and how much good habitat is out there is a reminder that this is a hard animal to survey, not necessarily a scarce one.
