American badger
The negative effect on distribution is evident in the Texas distribution of many wide-ranging specie of both eastern and western North American fauna reaching their respective distributional limits in the region of the Texas Blackland Prairies and East Central Texas forests [e.g. eastern: American alligator ("Alligator mississippiensis"), eastern gray squirrel ("Sciurus carolinensis"), southern flying squirrel ("Glaucomys volans"),; western: American badger ("Taxidea taxus"), western diamondback rattlesnake ("Crotalus atrox"); and other fauna listed below].
