From 1923, when the first culling of the herd took place, until 1935, when the administration of the Preserve was transferred from the Bureau of Biological Survey to the National Park Service, approximately 395 bison had been culled. This included 266 live for breeding, restocking or exhibition, 111 for meat, and 18 died of natural causes.
