National Park Service Extends Comment Period on Proposal To Vaccinate Yellowstone Bison

A plan to use air rifles to vaccinate Yellowstone National Park bison against brucellosis apparently is more controversial than initially thought. Park Service officials say due to interest and concerns over the project, they're extending the comment period on the draft Environmental Impact Statement another 60 days.

The move to develop such a "remote vaccine" was called for in the Interagency Bison Management Plan adopted back in 2000. If adopted, the program would be the latest evolution of brucellosis control in the park, though it certainly wouldn't mollify critics of how Montana officials haze bison back into the park, sometimes with helicopters, at various times of the year.

While the original 60-day comment period was scheduled to close July 26 -- Monday -- park officials announced Friday that they would keep it open another two months.

The purpose of remote vaccination of bison inside the park is to reduce the brucellosis infection rate in order to increase tolerance for bison on historic and essential winter range outside the park in Montana when cattle are not present. The park believes the most logical method for remote delivery of the vaccine is to use a compressed air rifle to deliver an absorbable projectile containing the vaccine.

... Due to public interest and concerns about uncertainties disclosed in the Draft EIS, the National Park Service has decided to extend the comment period for an additional 60 days.

The Draft EIS and an electronic form to submit comments on the Internet can be found at the National Park Service’s Planning, Environment and Public Comment (PEPC) website at http://parkplanning.nps.gov/yell. The Draft EIS is also available on CD or in hard copy by writing the Bison Management Program, P.O. Box 168, Yellowstone National Park, Wyoming 82190.

Written comments may be submitted through the PEPC website, in person, or by mail. Comments will not be accepted over the phone, by fax, or e-mail. All public comments must now be received or postmarked by midnight, September 24, 2010.

Yellowstone is home to the last free ranging and wild herd of pure plains bison. Between 40 and 60 percent of the bison have been exposed to the bacteria which causes brucellosis; a disease which can induce abortions or the result in the birth of non-viable calves in both cattle and wildlife.
