Wolf pack known for close encounters exits Bow Valley

- SPENCER VAN DYK

The Bow Valley wolf pack, which was as strong as five last summer, is no more.

The breeding pair that arrived in the valley around the summer of 2014 has since mated and moved on. Of the six pups they had last summer, none survived and they were left with only the three they bore in 2015.

“It’s very easy for wildlife to become conditione­d and as soon as they taste human food, they can become instantly hooked on it and unfortunat­ely that increases their risk of mortality,” said Parks Canada wildlife ecologist Jesse Whittingto­n, adding it is also more dangerous for humans when animals become immune to aversive conditioni­ng.

The breeding female and one of the yearlings were destroyed last year after they became habituated to people and had several close human encounters.

The breeding male also left the Bow Valley and joined another pack this spring and there have been no signs of the remaining yearling for about a month.

As of last winter, the pack was down to three: the breeding male and two pups. One of those yearlings wandered into B.C., where it was later shot.

Whittingto­n said there have still been sightings of single wolves, but no pack, not unusual considerin­g the vast range the animals have.

He said wolves have a “phenomenal influence on the entire ecosystem,” because they keep the number of prey in check, mostly grazing animals that can become too numerous and, in turn, have a cascading effect on the system.

“We’re hopeful that wolves will have another pack formed in the next few years, but for this year, I would expect that deer, elk and moose in the Bow Valley will have higher reproducti­ve rates and higher survival rates,” he said.
