The Montana Legislature will consider year-round bison hunting and prohibitions on the animals' movements amid a slew of bison-related measures during the second half of the Legislature.
    
Senate Bill 143 is one of the most contentious bills this session. It would extend the bison hunting season from its current three months, increase the number of bison that could be killed, and prohibit the transfer of wild bison.
    
Supporters say the animals can cause property damage on farms and ranches. They also worry about the spread of brucellosis- a disease that causes cattle to abort their first calf.
    
Opponents, however, say the bison population could be devastated by a year-round hunting season, as it has in the past.
