Pyrenean Frog

Rana pyrenaica

Endangered

At very high risk of extinction in the wild in the near future.

Spotted something wrong?

The Pyrenean frog is an anuran amphibian of the family Ranidae. The species was described in 1993, settling the controversy over the presence in the Pyrenees of Rana iberica, which it resembles morphologically. Recent genetic studies suggest that it may be more closely related phylogenetically to Rana temporaria than to R. iberica. It is an endemic amphibian, found almost exclusively in Spain, together with a few scattered localities in France along the border with Navarre, in the Irati Forest.

Fun facts

  • GeneralDescribed as a species in 1993; one of the rarest frogs in Europe.
  • It was described in 1993, a remarkable date for a European vertebrate: it went unnoticed for centuries because of its tiny size, its secretive habits and its resemblance to the common frog, with which it shares its habitat.
  • Its entire world range fits into a strip of the western and central Pyrenees, almost all of it on Spanish soil: Spain is directly responsible for its conservation.
  • It depends on cold, well-oxygenated streams in mature woodland, and rising temperatures and falling summer flows are pushing it to ever higher ground.

How to help

The pyrenean frog is classified as endangered. Organisations such as the IUCN, WWF and the Wildlife Conservation Society work specifically on its conservation and that of its habitat; looking into their programmes is a good starting point if you want to get involved.

It's documented in 2 protected areas — one reason why protecting these places matters for its conservation.
