Which small carnivorous mammal was thought to be extinct in Arkansas but has made a slow return?

The River Otter is the small carnivorous mammal that was once believed to be extinct in Arkansas but has since made a gradual return to the state. This improvement in their population can be attributed to various conservation efforts and natural habitat recovery, which have allowed the otters to thrive once more in waterways throughout Arkansas. The species is well-adapted to aquatic environments, where it plays a crucial role in maintaining the health of ecosystems through its diet, which includes fish and other small aquatic animals.

Understanding the history of the River Otter's decline and subsequent recovery highlights the importance of wildlife management and conservation in Arkansas. Efforts to mitigate habitat loss and protect these animals from overexploitation have facilitated their comeback, illustrating the effectiveness of dedicated wildlife management practices. The other options do not reflect a similar history of presumed extinction followed by a successful recovery in Arkansas.
