In the next three to five years, the National Park Service will reduce the size of the House Rock bison herd through capture and relocation and lethal culling. The Environmental Assessment, Finding of No Significant Impact and other documents can be found on the NPS Planning Environment and Public Comment (PEPC) website.

Operational details of herd reduction are being worked out and more information, including volunteer opportunities, will be announced at a later date through a news release. The information will also be available on our bison hotline 928-638-7900 and on the park web site
