Alabama’s marsh rice rat records are sparse for a species that has some of the best wetland habitat in the country waiting for it: the Mobile-Tensaw Delta, one of the largest river deltas in the United States, spreads across the state’s southwest corner as flooded forest, tidal marsh, and backwater swamp. A scattering of additional records comes from wet creek bottoms near Tuskegee National Forest, closer to the Black Belt.
A rodent that swims through flooded grass
The marsh rice rat builds runways through standing marsh grass and swims readily between them, feeding on seeds, green plant material, insects, and small aquatic animals it finds along the flooded edges. That combination of dense grass cover and shallow water is exactly what the Delta offers on a scale few other places in Alabama can match.
Why the record count stays low
Wetland rodents like this one are difficult to survey. They’re active mostly after dark, spend much of their time in dense marsh vegetation that’s hard to walk through, and rarely turn up in casual observation the way a more visible mammal would. A low record count in the Delta almost certainly understates how much of that habitat the species actually uses.
Status in Alabama
NatureServe ranks the marsh rice rat S5, secure, and it’s native to its Alabama range. The IUCN lists it as globally Least Concern, and its biggest advantage in this state is simply having one of the largest intact river-delta wetlands left on the Gulf Coast.
