Salamander Crossing to Provide Squish-Free Passage

Posted June 16, 2008 4:56 PM

From CBC | Technology & Science News:

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."

Here in the UK we use one foot dia, pipes under all major roads that are known frog and toad crossings when they are going to their spawning pools.

We also have special road signs on smaller roads when the spawning season starts, this is so motorists can slow down when these animals are crossing the road.

Hey Scapolie,

That's very interesting that your Department of Transportation actually has road signs put up when the amphibian migration season starts. I wish we had that here in the States or at least in Upsate New York.

I do research every Spring at the Saratoga National Historical Park in Saratoga Springs, NY tracking the migration of frogs and salamanders to and from their oviposition sites. There is a tour road that runs through the park and a major US route that runs through the very eastern portion of the National Park lands. Right now there are no pipes running underneath these roads and no signs indicating that there are migratory routes running across those roads. Hopefully, the research I'm helping with will get these migration routes "piped."

I was witness to another case where infrastructure piping would have been a good idea when a major 4 lane highway was built through the Montezuma National Refuge in western New York. One Summer, the wetlands in the refuge had become so dry that the giant tortoises that lived in the refuge, were migrating across the four-lane highway(!) to find deeper wetlands. I, unfortunately, saw a couple tortoises turned over on their backs in the middle of the highway while tractor trailers were speeding by them at 80 mph (~130km/h)! I wish there were pipes under Interstate 90 and those areas like the refuge to allow animals to migrate in extreme conditions.

It's "Be Kind to the Wildlife" in Canada year.

Evidently nobody thought about the salamanders, when that kerbing was designed and installed.

Kind Regards....
