Beavers could play an important role in saving dwindling frog populations, according to new research by a PhD student at the University of Alberta.

Cameron Stevens's research, published in the January issue of Biological Conservation, shows that male frogs in the western Alberta foothills only call to woo female frogs when they are near a beaver dam.

"We showed that beaver can benefit amphibian populations, which are declining worldwide, including Alberta," Stevens said.

Dispelling idea of beavers as pests

Stevens studied frogs between Drayton Valley and Nordegg. Ponds created by beaver dams are a warm, nutrient rich environment for tadpoles, and are especially crucial during dry spells, he said.

One of the aims of his research is to get farmers and industry thinking differently about the beaver, said Stevens.

"The challenge I think will be for industry and land managers to adopt conservation plans for beaver, which as you probably know, are often considered a pest."

Stevens said he grew up listening to frogs and wants his children to hear their song.

"Amphibians are important components of the ecosystems," he said. "You take out amphibians, it's going to have a domino effect on other animals and species in that system."
