Greg Schroeder (National Park Service) and a pair of Auburn University graduate students approach a prairie dog that has been trapped outside its burrow in Wind Cave National Park. The animal is part of a field test to determine the effectiveness of a USGS-developed oral sylvatic plague vaccine (SPV).

Over 30 organizations and agencies are 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.

This prairie dog was trapped by scientists outside its burrow in Wind Cave National Park as part of a field test to determine the effectiveness of a USGS-developed oral sylvatic plague vaccine (SPV). This animal will be brought to a research van for tagging and blood, whisker, and hair sampling, and then released.
