There is a huge problem at Banff NP because of the 4-lane Trans-Canada highway that bisects the Park. There are also way too many elk in the Bow River Valley near the town of Banff.
An experiment is underway to try to make fences and highway underpasses tilted in favor of elk predators.
Use of underpass fencing sets up Banff elk for predators. Officials hope experiment will reduce numbers. Cathy Ellis, Calgary Herald
