MESA COUTNY, Colo. The Bureau of Land Management presented the Colorado Volunteer of the Year Award to five people who participate in a darting team for fertility control.
"It does so much for the horses, and the range and the wildlife that I'm just so glad to be a part of it," said volunteer Georgia Manus.
The volunteers said it's a humane way to control the population and help the animals thrive. It's been a successful program since 2002.
