About Black Bears
Black bears are the smallest of American species, less physically impressive than grizzly or Kodiak bears and much less dangerous than polar bears. However, they still range over much of the country and should be treated with respect when they're encountered. A well-grown black bear can exceed 800 lbs. in weight, and they are strong enough to bring down a full-grown elk. Their claws are capable of causing tremendous wounds, and their jaws exert enough force to bite through heavy bones.
Speed
The normal gait of a black bear going about its business is a relatively relaxed, shambling stroll. Although it looks awkward, bears can cover an astonishing amount of ground without appearing to hurry. Depending on the terrain, one individual bear will stake out and patrol an area as large as 100 square miles in that same steady stride. When bears are attacking or retreating they are capable of great speed over short distances, usually estimated at 25 to 35 mph. This is much faster than a human can run, making flight a poor option when encountering a bear.
Bear Encounters
Although bear populations have diminished through most of the contiguous 48 states, they can be encountered in wooded areas almost anywhere in the country. If you see a bear, stay calm and don't run. Back away slowly, making soothing noises. Stand up straight and spread your arms to make yourself appear bigger. A bear that stands on its hind legs is only curious, and trying to get a better look at you. If you've startled the bear, it may make a huffing, grunting noise and charge at you. This is a bluff. Just back away slowly, until you are out of sight.
Avoidance
If you see a bear, it usually means he didn't hear you coming. If you hike in an area known to have bears, make noise to announce your presence. If you choose to jog in the woods, remember that running is "flight" behavior that can trigger bear aggression. Be alert at all times and don't wear headphones. If your home is in bear country, be especially careful about securing your trash. Bears are attracted to food waste, the smellier the better, and are both creative and destructive in their determination to get into it.
