Which mammal, once eliminated from Arkansas, was successfully reintroduced in the Ozark and Ouachita mountains?

The Elk is the correct answer because it was historically present in Arkansas but faced extinction in the region due to overhunting and habitat loss. In the 1980s, conservation efforts led to the reintroduction of Elk into the Ozark and Ouachita mountains. These efforts were aimed at restoring the native wildlife population and enhancing ecological balance in the area. The reintroduction has been successful, and Elk populations have since thrived, becoming an important part of the local ecosystem and a popular attraction for wildlife enthusiasts. The project's success reflects effective wildlife management and conservation practices within the state.

The other mammals mentioned either were never eliminated from Arkansas or were not part of reintroduction efforts like the Elk. For example, while the Wild Turkey is an important species in Arkansas, it was not eliminated from the state in the same manner as the Elk. Black-tailed Deer are primarily found in western regions and do not naturally occur in Arkansas, while the North American Beaver has maintained a presence in Arkansas and has not undergone a similar reintroduction process.
