From the New York Times:
You like caribou. You like wolves. How do you preserve one without killing the other? Research supporting an unusual conservation approach suggests that it may have something to do with hunting moose, at least in one region of North America.
Scientists spent a decade monitoring wolf, moose and endangered mountain caribou populations in the remote rain forests of southern British Columbia. In a study published Tuesday in the journal PeerJ, they found that if you let people hunt more moose, you get fewer wolves and more caribou. While this approach may only be part of the solution for preserving the caribou, it illustrates the complexity of conservation in natural environments.
