Translocate frogs Amphibian Conservation

A before-and-after study in the UK (Wilkinson & Buckley 2012) found that a small population of pool frogs Pelophylax lessonae was established from translocations. The frogs were healthy and had good survival rates, but the population did not grow as anticipated. Not all of the ponds were used by the frogs. In 2005, adults, juveniles and tadpoles were collected from Sweden and released at a recently restored site. Releases were repeated three times. Individual frogs were monitored.


Head-start amphibians for release Amphibian Conservation

A replicated, before-and-after study of agile frogs Rana dalmatina at two sites on Jersey, UK (Wilkinson & Buckley 2012) found that following the release of head-started metamorphs, breeding increased at both sites. The number of egg clumps increased by approximately 500% and the number of breeding ponds occupied increased compared to five years previously. Tadpoles were held in captivity until metamorphosis and then released at existing, re-profiled and newly created ponds at two sites.
