Four miniature tunnels have been built in a national park south of Calgary to save hundreds of migrating salamanders from being squashed to death by traffic.
The special underpasses open this week in Waterton Lakes National Park, about 270 kilometres south of Calgary, to allow long-toed salamanders to safely cross a busy roadway as they migrate to and from Linnet Lake.
The amphibian tunnels — a first for Canada's national parks — are a miniature version of the underpasses and overpasses Parks Canada already uses to help wildlife, including bears, wolves and elk, safely cross highways.
In the early '90s, Parks Canada installed a new sidewalk along the lake and it soon proved to be a major barrier for the salamanders.
"The salamanders were just piling up there against that curb," explained Parks Canada biologist Cyndi Smith. "They were trapped against there and then a lot of them were getting killed."
