"Yellowstone National Park is proposing to reduce its celebrated bison herd by 1,000 animals this winter by rounding up those wandering into adjacent Montana and delivering them to Native American tribes for slaughter, officials said on Wednesday.

The longstanding but controversial annual culling is designed to lessen the risk of straying Yellowstone bison infecting cattle herds in Montana with brucellosis, a bacterial disease carried by many bison, also known as buffalo.

Yellowstone bison, the nation's last sizable herd of wild, purebred buffalo, are a top attraction for the millions of tourists who annually visit the park, which spans parts of Wyoming, Montana and Idaho."
