Detailed Description

USGS scientist Tonie Rocke is working to immunize populations of free-ranging prairie dogs against plague with an oral sylvatic plague vaccine (SPV). If successful, the SPV could help protect endangered black-footed ferret populations in the western U.S. because the ferrets rely on prairie dogs for food.

The SPV project is a collaboration of over 30 organizations and agencies.
