I thought the OP was about black bears in a specific area, one I never visited.
My experience when paddle camping wild areas (AK, WY, CO) was that sometimes I would see signs they had been around.
In grizzly country in AK, we just decided to NOT CAMP THERE. Even so, one night I heard something moving around not far from our tents and in the morning found huge grizzly prints and the flattened vegetation where it had sat or lain. Not right near tents but not that far away. We knew it was time to be extra-cautious—the salmon run had just begun. That’s the closest encounter we had.
In contrast, black bears that consider human presence a signal of easy scrounging have been a worse problem. Where we used to live, people left their garbage bins out the night before pickup even though both the trash companies AND the state wildlife dept repeatedly told people to put it out only the morning of pickup. We always, always followed this advice.
People also left bowls of pet food outside, another bad habit.
Unfortunately, right when we moved into that house my husband ignored the seller’s warning not to store bird seed in the built-in under-bench boxes in the front porch. My husband ignored both his advice and my reiteration of it. The predictable happened not long after that. I awoke to loud banging sounds, turned outside lights on, tried to wake up my near-deaf-and-sleeps-like-corpse husband to no avail, and then I ran down to YELL at that bear while waving my arms around. It was hitting the Plexigas porch windows. The bear ran away…and returned within half an hour. I again hazed it and this time it stayed away.
I was livid. My husband finally figured out that the warnings were valid and never stored food in there again. When I called the wildlife dept they said that in late summer bears forage up to 20 hours a day! They advised spraying ammonia around the porch to mask the seed scents for a few days, to keep the bear from becoming a repeat visitor. It worked. No more bear trouble after that, and we lived there for 15 years, among not only black bears but also mountain lions. We left the claw marks in the redwood siding even when we got the buildings professionally restained. Good warning to the next owners!
Yellowstone NP requires backcountry campers to go through bear orientation. Do not ignore. They also have rules on how to store food. Do not ignore. Heeding these rules, we never had trouble there on any of our several backcountry camping trips there. Also, if bears have been reported too many times in a certain area, there will be posted advisories. I think there was even a temporary closure of a few sites at least one time.
Ironically, black bears sometimes migrate down to big subdivisions from the wilder areas. We read of this every.single.year happening in the fast-growing greater Durango, where too many people think it’s cool/amusing/“we’reCountryPeopleNow!” to leave garbage cans, uncleaned cooking grills, and of course DOG BOWLS outside (because getting a dog means they’re a local now!). Of course, all the bears care about all summer and early fall is gorging themselves. The subidivisions turn into bear magnets and the complains to relocate roll in.
Wildlife dept says they want to move bears into the wilder areas. I personally know from observing bears and deer that even though they might retreat to wilder areas, the easy living of garbage, dog food, food scraps left around (bear magnets) and cattle pasture, provided water, fruit trees, and relative protection from poaching (deer magnets) means that I see MORE deer in pastures than in the wildlands.
So far, in my location, black bears seems to avoid getting near humans. We see them once in a great while on gamecams or see their tracks and scat. They’re still wild enough not to hang nearby. But the suburban or exurban subdivisions full of careless people and pets are a different story. Don’t give them any hope of easy food.
