It’s a wet and wild episode 22! We’re joined by national beaver specialist, Mark Elliott, down in the Knepp beaver pen after a night of heavy rain. We marvel at the amazing work of the beavers - how they’re creating the most wonderful wetland area that’s holding on to water during winter floods and providing an oasis for life during droughts.  We tap into Mark’s encyclopaedic knowledge of the natural history of beavers in Britain: why they became extinct, how they’re making an incredible come-back and the amazing benefits they bring to wildlife and us humans too.
