A project that has been running for 11 years to save the agile frogs species from extinction is "working brilliantly" according to the Durrell Wildlife Conservation Trust.
Previously, the frogs could only be found around Ouaisne Common, but efforts to introduce the species to other areas of the island have been successful.
Durrell's breeding programme has seen over 50,000 tadpoles released into the wild in total.
The frogs now live across the island, but Matt Goetz from Durrell says it is a "long-term commitment" to ensure the species continues to grow.
