Underreported: America's Last Wild Buffalo

America's last herd of wild buffalo are in Yellowstone. When they wander outside of park limits, they are vulnerable to "hazing" - i.e., capture and slaughter - because ranchers and the Montana Department of Livestock fear that the buffalo can transmit brucellosis to cattle. But some scientists and activist groups like the Buffalo Field Campaign say that the threat of brucellosis transmission is extremely low, and the buffalo are an essential part of the plains ecosystem and need to be protected. Journalist Christopher Ketcham has written an article about the fight over the buffalo in the June Harper's magazine.
