FILE - In this April 20, 2014 file photo, a group of bison graze along a state highway near West Yellowstone, Mont. Montana officials are reviving efforts to craft a statewide bison-conservation plan that stalled amid a backlash from ranchers worried about new herds competing with cattle. A broad strategy for managing bison in Montana has been in the works since 2010. Concerted opposition from ranchers has slowed the initiative, and officials recently scaled back expectations for bison in new areas. (AP Photo/Matthew Brown,File) less
