Grizzly bears were here first, but they were quickly killed by the pioneers in the 1890s. Black bears were introduced in the mid-twentieth century and are much more tolerant of people. We now have a stable Black bear population in the forest.
Bears usually avoid people, but their responses are unpredictable.
A female may be quickly provoked if her cubs are disturbed or if you come between her and the cubs. Bears don't like surprises. Make your presence known by singing, talking, wearing bells, or making other noises. Hike in groups. Do not hike after dark.
