Plague Vaccine Testing Signage in Wind Cave National Park

Detailed Description

Wind Cave National Park is one of 34 areas testing a USGS-developed oral vaccine to prevent the spread of plague in prairie dogs. If successful, the sylvatic plague vaccine could help protect endangered black-footed ferrets in the western U.S. because the ferrets rely on prairie dogs for food. The project is a collaboration of over 30 organizations and agencies.
