A keystone species that went invasive due to human interference. This episode is all about what happened when a small group of beavers was taken from their native home of North America to the southern tip of South America. Part one is just facts about how they ended up there and part two is a fictional story partially based on true events. It's so you can hear the phrases and words in sentences. I hope you enjoy it!
