New Banff fence will zap bears who try to climb it to eat roadside dandelions – CBC.ca

Banff National Park is trying a new strategy to keep bears off the highway.

The park recently installed five kilometres of electrified wire along fencing on the side of the TransCanada highway, east of the Banff townsite.

Dan Rafla, a human-wildlife coexistence specialist for the park, said every summer, parks staff will see black bears climb the fence to eat dandelions and berries on the other side.

"In spring through June, we'll actually see a pulse of activity of bears crossing over the fence," he said.

"Then it might peter off into July as the snow melts off the landscape, grass grows elsewhere, and the animals follow that green wave up the mountains. Then we might see it again in August as buffalo berries come online in the valley bottom."

Staff havealreadyremoved berries and other food attractants from the highway side of the fence,and have replaced and upgraded fences to prevent animals burrowing underneath.

Now, the new wiring, installed far from any human trails a few weeks ago,will deliver strong but non-lethal zapsto encourage the bears to wander off in search ofa safer place to cross.

And Rafla said it's working so far.

"Unless something radically different has happened, that area where the hot wire [was installed] has been a traditional hotspot for bears climbing over for years and we haven't had one yet this year."

Rafla said they'll be assessing the wire's effectiveness over the course of the summer.

They have also introduced warning signs and highway speed reductions near those trouble spots to remind drivers to stay alert.
