Utah’s Henry Mountains Reveal Rare Pure American Bison Herd
Most American bison today are not genetically pure, having been extensively crossbred with domestic cattle in the 19th century. This hybridization aimed to create animals with bison hardiness and cattle docility, resulting in semi-domesticated herds. Historically, only two known genetically pure herds existed in the U.S., located in Yellowstone and Wind Cave National Parks.
A significant discovery in 2015 revealed a third, truly wild, disease-free, and free-ranging population of approximately 350 genetically pure American bison in Utah's Henry Mountains. Originating from Yellowstone stock transplanted in the 1940s, genetic analysis confirmed no cattle genes. This herd is invaluable for species conservation and provides crucial insight: despite co-grazing on unfenced public lands with cattle, wild bison bulls demonstrated no interest in cross-breeding, challenging long-held assumptions.
Furthermore, the Henry Mountain bison are notably free of brucellosis, a venereal disease that plagues Yellowstone's bison and elk populations. While there's concern about brucellosis transmission to livestock, leading to controversial culling of Yellowstone bison, no direct wild bison-to-cattle transmission has been recorded. Conservation efforts are expanding, with genetically pure Yellowstone bison relocated to Fort Peck and Fort Belknap Indian Reservations. Montana has also expanded the range for Yellowstone bison on public lands, and the National Park Service now prioritizes relocation over slaughter, marking a pivotal step toward restoring these majestic, truly wild animals across North America.
