- Conservation efforts in Montana focus on tracking grizzly populations and attaching radio collars to aid in their recovery, despite human population growth leading to increased conflicts.
- Successful conservation efforts in areas like Glacier and Yellowstone National Parks have led to a tripling of grizzly populations and range expansion.
- Despite efforts to coexist with grizzlies through measures like installing electric fences, conflicts persist, leading to the euthanization of bears deemed a threat to human safety.
- Zoos have shifted focus to conservation, managing breeding internally using software to prevent inbreeding and maintain genetic diversity.
- The American Prairie aims to create the largest Nature Reserve in the contiguous United States, restoring Bison populations and collaborating with ranchers for sustainable practices.
