Good winter for bison

From ANIMAL PEOPLE, March 2010:

WEST YELLOWSTONE–Montana hunters killed only one bison who
roamed out of Yellowstone National Park during the winter of
2009-2010, after killing only one the previous winter. The state
issued 144 bison tags to members of the Nez Perce tribe, and 144 to
other Montana hunters.
During the harsh winters of 2005-2006 and 2006-2007 more than
1,000 bison were either shot or trucked to slaughter after testing
positive as potential carriers of brucellosis, feared by the Montana
cattle industry, but few bison left Yellowstone during the mild past
two winters.

With less work to do protecting bison from being shot or
slaughtered, the Buffalo Field Campaign on January 15 removed two
miles of abandoned barbed wire fencing from a wildlife migration
corridor within Gallatin National Forest.
The Bureau of Land Management is coordinating a similar
volunteer fence removal project at Carrizo Plain National Monument in
California, primarily to help young pronghorn antelope, who are
often cornered against old fencing by coyotes.
