Bison are generally not aggressive but will defend themselves when they feel threatened. Visitors should be especially cautious during the mating season when bison are more prone to agitation.

Visitors should exercise extra caution in these high-risk areas, especially during peak tourist seasons when bison are more active and visitor numbers are higher.
