Wind Cave NP bison translocated to Mexican TNC site

Last Monday morning, 23 of the 277 bison brought in during the annual roundup at Wind Cave National Park were loaded in a semi-trailer and shipped to a Nature Conservancy-managed property in Mexico. The translocation project will establish a satellite herd on grasslands in Chihuahua that are part of the species’ historic range.

Back in 1911, the American Bison Society selected Wind Cave National Park as one of the first areas where free-roaming bison herds would be re-established in their historic range. The stocking program, part of a campaign to rescue bison from the brink of extinction and restore their numbers to healthy levels, was a rip-snorting success. Today Wind Cave’s bison herd numbers about 500 and is one of only two genetically pure (no cattle DNA) wild bison herds in the United States. And unlike the genetically pure herd at Yellowstone National Park, Wind Cave bison don’t carry brucellosis, a disease that poses a potentially serious threat to the cattle industry. Wind Cave is, in brief, the world’s only source of genetically pure, brucellosis-free wild bison.
