The pool frog is the UK's rarest amphibian. It was driven to extinction in the late twentieth century, largely as a result of habitat loss and degradation. Earlier this century it was returned via a reintroduction project using Swedish stock. Although still at the early stages, the results from the two reintroduction sites are promising. The increased interest in rewilding presents opportunities for pool frog conservation, since it could allow extensive restoration of habitat in the species' former range, including the Fens. Further reintroductions would be needed in order to re-establish populations, and as the species has such specialist habitat requirements, a rewilding approach would need certain characteristics to be beneficial to pool frogs. Fundamentally, an outcomes-based approach would assist with ensuring that objectives for pool frogs and rewilding are optimally aligned.
