A frog which has been extinct in สล็อตโรม่าฟรี England since the 1990s has been reintroduced to its original habitat after some were flown over from Sweden.
The northern pool frog was last found at Thompson Common, in Norfolk.
The Swedish specimens were introduced to a secret site in Norfolk in 2005 and tadpoles have since been successfully moved back to ponds at the common.
"That means we can reverse extinction, and it's not often you can say that for an animal," a conservation group said.
Jim Foster, director of Amphibian and Reptile Conservation, said the frog became extinct in England as declining water levels made their breeding ponds unsuitable.
He said the landscape at the Norfolk Wildlife Trust's Thompson Common site, near Thetford, had been improved, with ponds holding water for longer and trees removed from some areas as "pool frogs are real sun lovers".
About 30 adult northern pool frogs per year were flown over from Sweden between 2005 and 2008, Mr Foster said.
