In the next three to five years, the National Park Service will reduce the size of the House Rock bison herd on the Kaibab Plateau 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.

No lethal culling will take place during 2019. Operational details of future herd reduction are being worked out. More information, including volunteer opportunities, will be announced at a later date through a news release. This website is the best source of up-to-date information.
