Here they go again! 🦎
It’s time for Alberta’s fall salamander migration! After spending the past few months at their summer breeding grounds, western tiger and long-toed salamanders are now heading back to their underground overwintering sites.
These salamanders are two of the ten amphibian species who call Alberta home. Due to their nocturnal, burrowing lifestyles, they have always been difficult to observe. Unfortunately, they are becoming increasingly difficult to find as they face the combined threats of habitat loss, climate change, pollution, and disease.
Development can reduce amphibian populations through habitat loss and fragmentation. Barriers like major roads make it difficult for these slow, small species to move between habitats, and vehicle strikes are estimated to kill between 40 and 100% of migrating salamanders in some areas. However, through data-informed planning, there are still opportunities to support these salamanders and other amphibians!
Last year, the Miistakis Institute was involved in researching and monitoring eco-passages in Waterton Lakes National Park. These specialized tunnels run underneath roadways, providing safe passage for migrating amphibians, and reducing amphibian fatalities by up to 80%. Camera trap monitoring revealed that both tiger salamanders and long-toed salamanders are using these crossings, along with many other small species!
Sharing this data supports wider amphibian conservation efforts and provides further evidence that targeted infrastructure can help vulnerable species move across the landscape.
