The complete county distribution, spread across 2 Oklahoma counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Oklahoma’s occurrence databases hold just 14 records of the coypu, all logged through GBIF, clustered around Red Slough Wildlife Management Area, Ouachita National Forest, and Beavers Bend State Park. That’s a thin count even by the standards of a species with no wild range in North America to begin with.

The wettest corner, and nowhere else

Every one of Oklahoma’s coypu records sits in the same far southeastern corner of the state, the bottomland hardwood wetlands and forested foothills around the Red and Mountain Fork rivers near the Arkansas and Louisiana borders. That’s the natural edge of the Gulf Coast marsh country where escaped fur-farm coypu took hold and spread through Louisiana and Texas in the twentieth century. Oklahoma’s much drier interior and Panhandle offer nothing like that habitat, which is likely why records don’t extend anywhere beyond this one wet pocket.

A record, not a colony

USGS NAS lists just a single nonindigenous coypu occurrence in Oklahoma, with no report of an established colony. That’s a real contrast with the Gulf Coast marshes, where dense colonies strip the root mat out of wetland vegetation and leave behind bare, waterlogged scars. Oklahoma simply doesn’t have the extensive coastal marsh substrate that fuels that kind of spread elsewhere, so a coypu turning up here more likely reflects an isolated wanderer or escapee than a colony taking hold.

Status in Oklahoma

The coypu is not native to Oklahoma. USGS NAS records one nonindigenous occurrence in the state with no established colony reported, and NatureServe lists it as exotic with no S-rank applicable (SNA), against a global rank of G5.
