The American beaver turns up in slow water across a wide stretch of Arkansas, and the state’s occurrence databases hold 299 records, most of them iNaturalist entries. That count reflects who went looking and where, not how many beavers live in the state.
A dam builder that doesn’t care which river
A beaver needs slow water, woody plants within reach of the bank, and enough depth to hide the underwater entrance to its lodge, and Arkansas offers all three from the Ozarks to the Delta. Records reach the Buffalo National River’s spring-fed pools in the northwest, the oxbow lake at Wapanocca National Wildlife Refuge in the Delta’s northeast corner, a cutoff bend of an old Mississippi River channel, and the bottomland hardwood forest where the Ouachita and Saline rivers meet at Felsenthal National Wildlife Refuge in the south. A clear mountain creek and a muddy Delta slough work the same for a beaver as long as there’s wood to cut and water deep enough to build in.
Built to outlast winter
It cuts bark, twigs, and aquatic plants and jams the branches into the mud near its lodge, an underwater pantry it can reach once the surface freezes or floods high. That stockpiling season runs into late winter, and Arkansas’s records peak in April and May, right as the work of repairing dams and restocking a larder becomes easiest to see from the bank.
Status in Arkansas
NatureServe ranks the American beaver S5, secure, and the USGS Nonindigenous Aquatic Species database doesn’t list it as introduced here. It’s native across the state, and a record spread that runs from Ozark headwaters to Delta oxbows fits an animal that adapts one skill, damming slow water, to whatever water it finds.
