Castor canadensis Kuhl, 1820

American Beaver

Castor canadensis was once widespread across the state. Dramatic declines due to trapping resulted in Blair (1939) suggesting that the species was extirpated from the state. Since that time, populations have increased statewide. Roehrs et al. (2012) reported a new specimen county record for McCurtain County. New specimen county records are reported for nine counties, including Garfield, Muskogee , Nowata , Oklahoma , Osage, Rogers, Seminole, Tulsa, and Washington.
