In this thread and elsewhere, there have been mentions of black bears, at least, mostly ignoring humans and just going about doing bear things. Grizzlies are far more dangerous. But in my one-time experience one has to be cautious around any bear, including the black bear.
One year when a friend and I were camping in remote wilderness – a designated wilderness park, but remote nonetheless – it was apparently a poor season for the berry crop and hungry bears were foraging farther than usual, including into small towns. At one point we’d had a mama bear and her two cubs visit our campsite twice. We had properly strung up perishable food on a rope between two trees where they couldn’t reach it, but Mama Bear got into supplies that we thought would be safe, like canned goods that Mama Bear actually opened with her teeth.
I was getting a little concerned, but the problem was solved for us when the bears went over to another campsite across the lake where some foreign tourists did not know enough to keep food out of their tent. The bears barged in for the food, and though the couple wasn’t hurt, they were terrified and their tent was completely demolished. It was their report to the park office that sent a couple of park rangers our way, armed with both a tranquilizer gun and rifles.
They asked if we had encountered the bears. Then they kindly offered to paddle off across the lake so as not to further disturb us. I begged them to stay! They fried up some aromatic steak over a campfire to attract the bears, and sure enough, in comes Mama Bear and the two cubs. The plan was to tranquilize Mama and then relocate her and the two cubs much farther north.
Sadly, Mama Bear was unhappy about being stared down by us and the two rangers, and rose up on her haunches in a distinctly aggressive move. I still think she should have been tranquilized but this was too much for one of the rangers and he shot her. I think I’ve posted about this incident before. It was one of the most horrible things I’ve ever experienced.
The good news was that the two cubs were later found and were successfully relocated, and park staff told me they had seen evidence that the cubs had learned to forage and were capable of looking after themselves.
But the moral of the story is that I wouldn’t regard even a black bear as necessarily benign, although I sure as hell wouldn’t shoot one unless it was a life or death situation. I would just keep my distance.
