New series in which Hannah Stitfall and a guest discuss one of her picks from the LIVING WORLD archive. Today they eavesdrop on an encounter at a secret location in Norfolk with the UK’s rarest frog, the pool frog. The frogs were introduced here from Sweden over a decade ago, after the last native East Anglian pool frogs died out in the wild and their progress has been carefully monitored. As well as the frogs there’s a very smelly encounter with a couple of grass snakes!
