During the Working of the Bison, the animals are sorted and separated one at a time to receive their vaccinations. They receive individual health screenings that include checks for pregnancies, parasites, and health issues.
Free public tours and media opportunities are available all three days of this phase. Educators and other group organizers: please reserve group tours by emailing dpittz@utah.gov. Group reservations are limited and tours are not guaranteed for groups without reservations.
November 4
Bison Auction
The manageable herd size for bison on the island is between around 500-550 bison, and each year there are between 100-200 calves born into the herd. With no natural predators on the island capable of taking down a bison, it is necessary to artificially reduce the herd size to balance out the food supply.
By selling excess bison at a public auction, park staff are able to keep the herd within a number the habitat can support. Ideally, the plan calls for a herd size of about 550 bison. This will be an online auction. Contact bwmorris@utah.gov with any questions.
