Translocate frogs Amphibian Conservation

A before-and-after study in 2004–2011 of 71 Hamilton's frogs Leiopelma hamiltoni translocated from Stephens Island to Nukuwaiata Island, New Zealand (Tocher 2011) found that a breeding population was established. Production of juveniles, establishment of the new population and recovery of the donor population was slower than expected. However, by August 2011, repeated breeding had occurred and new recruits were almost at breeding age. There was no evidence of a decline within the donor population. Frogs were translocated between May 2004 and July 2006. Both the translocated frogs and donor population were monitored until 2011.
