THREATENED SPECIES -- Our big bears need lots of room to roam, something that's in short supply in our ever-more-developed world.
Grizzly bears in NW Montana face trio of obstacles
An estimated 45 grizzly bears reside in the Cabinet-Yaak Ecosystem in the northwest corner of Montana. In most cases, their lineage traces back to a female grizzly from British Columbia that was trapped and released to the area in 1993 to boost the population. The effort continues as the species struggles with isolation from other populations, conflicts with humans and habitat.
