A couple times a year, Angela Jarding heads to the grasslands in the middle of the night. She and other scientists are working to find and trap black-footed ferrets.
This species is so endangered that it was once thought to be extinct. Now, it's slowly coming back along with its main food source: prairie dogs.
We ask Jarding about the conservation efforts helping bring back the ferret and the important ecological niche they fill on the prairie.
Jarding is a wildlife biologist at Wind Cave National Park.
