 The red-billed chough "Pyrrhocorax pyrrhocorax" became extinct in Jersey around 1900, when changes in farming and grazing practices led to a decline in the coastal slope habitat required by this species.Birds on the Edge, a project between the Government of Jersey, Durrell Wildlife Conservation Trust and Jersey National Trust, is working to restore Jersey's coastal habitats and reinstate the red-billed chough (and other bird species) to the island

Jersey is the only place in the British Isles where the agile frog "Rana dalmatina" is found.The remaining population of agile frogs on Jersey is very small and is restricted to the south west of the island.
