The UK's Rarest Frog
Joanna Pinnock is at a secret location in Norfolk to see the rare pool frog which has been reintroduced after becoming extinct.
The UK's rarest frog is the pool frog and they can be found in ponds at a secret location in Norfolk. Although the last native English pool frogs died out over a decade ago, they were reintroduced here from Sweden in 2005-2008. Joanna Pinnock meets John Baker, a consultant specialising in reptiles and amphibians, who is monitoring their numbers. Joanna also comes face to face with a couple of grass snakes on site and encounters their very smelly defence strategy! Producer Brett Westwood
