"What if I see a black bear?"
This is probably the most common question we hear.
The standard answer nationwide is, "Speak calmly and back away slowly." This is good advice. It identifies you as a person, shows that you are non-threatening, and gives the bear space.
Is following this advice necessary to avoid an attack? No.
Those are polite actions that respect a black bear's comfort zone and help ease its anxiety. It is the gentle way to separate. More aggressive action would be more likely to increase a black bear's anxiety and send it running.
Which action is safest? If a black bear is more than a few yards away, it hardly matters. Attacks are extremely rare despite what people do. Fearful, unnecessary advice about what to do, or not do, when a person sees a bear is often given by well meaning people.
