Following an attack on a school group on British Columbia’s Central Coast, the B.C. Wildlife Federation is calling on the province to consider lifting the ban on hunting grizzly bears — but not everyone is convinced.

The footage is extraordinary in that grizzly bears hibernate during the winter, when the Yukon receives most of its snow. So it’s rare to document a grizzly at close range during a blizzard and before it has shaken off the snow.

Ranches in northwest Wyoming — and around the Mountain West — are turning to virtual fences to cut labor costs, prevent grazing overuse and get rid of barbed wire, which opens up migration corridors for elk or pronghorn. For Anson, preventing conflicts with grizzly bears is also a big motivator for using the new tracking technology.

The man wanders off the marked trail, and away from the group, towards a bear in the Hayden Valley area of Yellowstone National Park.

An update from the B.C. Conservation Officer Service says the investigation, including witness accounts, has found that additional bears were seen in Bella Coola at the time of the attack, which left three pupils and a teacher with major injuries.

The grizzly bear attack on a school group in Bella Coola this week was one of several high-profile sightings and attacks in B.C. this past year.
