Toad numbers in the UK have dropped by two-thirds in the past 30 years - now human patrols are getting involved to give them a much-needed boost.
BBC1’s Wild Isles will show how, in one Somerset village, an army of high-vis patrollers are out stopping traffic to allow the toads to cross the roads safely.
Sir David Attenborough tells viewers: “Common toads need freshwater in which to lay their eggs so she must find a pond - and that can involve a journey of several miles which is full of obstacles and dangers. Tens of thousands are killed every year.”
