Yellowstone bison face slaughter when winter snows force them out of the park to graze


Yellowstone National Park's high altitudes sometimes receive deep snowfall - when that happens, the bison who live there travel to lower areas to seek food. Outside the park boundary, however, they face corralling by Montana authorities who fear that they may transmit brucellosis to cattle. Brucellosis causes cattle to abort their fetuses, and is very costly to Montana's cattle industry. If the bison test positive, they're killed. Some years have seen a third of the bison herd killed. Here's an msnbc story about a judge's recent decision to deny a request from wildlife groups to stop the slaughter.
