Erethizon dorsatum (Linnaeus, 1758)

North American Porcupine

Erethizon dorsatum was suggested to be uncommon and to occur only from the Wichita Mountains westward into the Black Mesa region of Oklahoma ( Caire et al. 1989). Caire et al. (1989) reported specimens from 12 counties and observational records from three additional counties. Since then, specimens have been reported from Tillman (Stangl et al. 1992), Beaver, Carter, Cotton, Dewey, Kingfisher, McClain, Noble, Pottawatomie, and Woodward (Tyler and Joles 1997), Oklahoma ( Braun and Revelez 2005), Grady, Harper, and Texas (Tyler and Haynie 2001), Blaine ( Caire et al. 2008), and Tulsa ( Curtis and Curtis 2014) counties. Additionally, observations have been reported from Caddo, Jefferson, Logan (Tyler and Joles 1997), Cana- dian, Cleveland, Murray, Stephens (Tyler and Haynie 2001), Creek, Washington, Nowata, Delaware, Cherokee, Haskell, Garfield, Payne, and Washita ( Caire et al.

2008) counties. Specimen records and observations of this large rodent indicate that it has been expanding eastward across the state (Stangl et al. 1992; Tyler and Joles 1997; Tyler and Haynie 2001; Caire et al. 2008; Curtis and Curtis 2014). New specimen county records are reported for Caddo county.
