A number of ursine encounters have prompted officials to issue bear warnings around western Alberta.

Alberta Parks posted a warning this week after a grizzly sidled up to a tent full of campers.

“It looks as if the bear had stepped on the side of the tent and then stepped off, leaving a couple of tear marks in the tent," wildlife ecologist John Paczkowski told the Rocky Mountain Outlook.

The warning covers the campgrounds of Boulton Creek, Lower Lake and Interlakes, all in Kananaskis Country.

Bears break into cabins

There is also a bear warning in place for Jasper National Park, where two grizzlies broke into cabins last week in search of food.

Bear attacks in Alberta are rare. A larger concern for park officials is having to relocate bears that become accustomed to human contact.

If a bear becomes dependent on food left behind by people, officials usually try to relocate the animal, which is costly and can create issues with other bears' territories.
