Beavers Helping To Check Decline in Frog Population

Researchers from University of Alberta Canada, surveying streams in the forests of Alberta, believe that Beavers are helping to check decline in frog population. They believe the beaver dams may be providing favourable conditions for developing tadpoles. The scientists recorded large numbers (approximately 5,000) of male frogs and toads on streams that had beaver dams, but didn't record any on the free-flowing unobstructed streams. The beavers create an environment that seems to allow tadpoles to develop and grow. The findings have been published in the latest issue of journal Biological Conservation.
