$4906.25, according to a post by David Willcove, excellent conservation biologist. He points out that a Colorado rancher was fined $157,000 for illegally killing 32 bison that had wandered onto his land last winter. Willcove discusses the conflict between wildlife and livestock in terms of the fear of disease. Bison could transmit brucellosis to cattle, but, Willcove says,
There has never been a documented case of a wild bison transmitting brucellosis to a cow, but the mere possibility that it could happen is enough to cause the State of Montana to insist on the death penalty for all bison that wander outside the park boundary (unless they can be chased back into the park…but try making a bison go where you want it to go).
You would think it might be possible for livestock and wildlife to co-exist, especially in a place where it really is not a matter of life and death, and Willcove has some suggestions to achieve that. But don’t hold your breath.
