To Aid Ferrets, Vaccine Treats Planned for Prairie Dogs in Wyoming
CHEYENNE, Wyo. (AP) — Feeding vaccine nuggets to prairie dogs could help bring back a species of prairie weasel that almost went extinct.
Scientists thought the black-footed ferret was extinct until a Wyoming ranch dog brought a ferret home in 1981.
One of the biggest barriers to restoring the black-footed ferret to Western ranges is plague, a disease that kills prairie dogs by the thousand. Black-footed ferrets feed almost exclusively on prairie dogs, meaning plague can leave ferrets without enough to eat.
To help black-footed ferrets, the U.S. Fish and Wildlife Service and others plan to vaccinate prairie dogs against plague in several Western states later this year.
They will use all-terrain vehicles and possibly drones to disperse vaccine pellets across as much as 40 square miles of ferret habitat.
