PUEBLO — Thirty black-footed ferrets bolted from cages onto barren ranchland Wednesday, potentially launching a new approach to rescuing endangered species — and introducing a natural predator of prairie dogs.
Although the federal government, led by biologists in Colorado, has bred thousands of black-footed ferrets in captivity, they still do not exist as self-sustaining species in the wild.
Plague has attacked some released ferrets in other states, but the bigger problem has been landowners hesitant to allow an endangered animal on their land fearing liability if anything happens to it.
