The greatest threat to grizzlies today is conflict with people. Bears are often killed by wildlife officials once they start to frequent residential areas for easy meals of garbage, livestock, pet food and birdseed, or by hunters or hikers who encounter them in the field and shoot out of concern for personal safety rather than use bear spray.
Much of the grizzly’s habitat [1] has been lost or degraded as a result of development, road-building and energy and mineral exploration. And climate change [2] also poses new challenges to the bears; they are denning later, putting them on the landscape longer in the fall when unintended shootings by hunters are most common.
