According to a press release from the wild bison advocacy group Buffalo Field Campaign (BFC), the National Park Service (NPS) has captured a further 193 buffalo inside Yellowstone National Park, USA and plans to slaughter them all, bringing the number captured in the last month to 865 and the number killed to 779. Eighty-six calves were sent to the Corwin Springs quarantine facility earlier this year. As in January, Montana has refused to transport the buffalo to slaughterhouses, prompting involvement from the US Department of Homeland Security.
"Yellowstone officials are blatantly ignoring the will of the American people by slaughtering, rather than protecting, wild bison," said Stephany Seay of BFC. "Destroying nearly 800 of the country's last native wild buffalo to appease one small cattle ranch should be a punishable crime."

Some of the bison captured by the Park Service migrated onto or near the Royal Teton Ranch, owned by the Church Universal and Triumphant (CUT). The ranch is located within North America's largest wildlife migration corridor directly adjacent to Yellowstone's northern boundary. In 1999 US taxpayers spent $13 million on conservation easements to allow wild bison to access these lands. The government never finalised the deal.
Fear that bison may transmit brucellosis to the CUT cattle is the purported reason for the slaughter.

Wild bison are a nomadic species native to North America and once numbered 45 million. Today there are less than 4,500 wild bison in America, all members of the Yellowstone herd.
