As folks head outdoors to camp, swim and explore, it’s time to prep for potential run-ins with our wild neighbors – bears included.

Last month, a hiker in Wyoming surprised a grizzly bear, causing the bear to attack. The hiker was flown by helicopter to a hospital in Billings, Montana, where he received treatment.

Dr. Jamie Sherman, a wildlife veterinarian at the University of California, Davis, said black bears and grizzly bears are two of the most common in the United States. Most publicized cases of human-bear encounters are going to involve black bears, the smaller of the two, she said. 

“They’re startled (or) you catch them off guard, and then they feel threatened,” she said. “If they hear you coming from far away, they’re more likely to be moving away before you even get to them.”

What to do if you see a bear

Branndon Bargo, assistant director of outdoor adventure at Southwestern University in Texas, has had encounters with dozens of bears, especially while exploring wild Alaska. 

“I’ve been in parks like Grand Teton National Park, which is right next to Yellowstone, and just been hiking on a trail and seen a black bear … maybe two feet from the trail,” he told USA TODAY. “Here come these tourists … they walk up, and they just get right in his face and start taking pictures of it.”

Here’s a tip: don’t do that, Bargo said.

Instead, give bears space, he said. Most of the time, they have no interest in humans anyway, he said. 

But what’s also important is how you walk away. 

“You do not want to turn and run,” Bargo said. “If you see something that’s scary, you’re going to want to turn and run. A bear that wouldn’t have been aggressive now has this predatory response, and it sees this thing running and it wants to chase it.”

Running isn’t wise, partially because bears can run as fast as horses, and, well, humans can’t, Bargo said.

“You just stop what you’re doing and let the bear kind of move its way,” he said. “You’ll be perfectly fine.”

He also stressed treating each bear uniquely because they’re not all the same.

For example, in grizzly bear territory like Montana, parts of Wyoming, Alaska and Canada, it’s best to travel in groups of six or more people, he said.
