Hamilton's frog

A two-phase translocation of Hamilton's frog (Leiopelma hamiltoni) into Zealandia Ecosanctuary Te Māra a Tāne, in Wellington, was the first attempt to restore the species to the mainland. All non-native mammals had been eradicated there, but house mice (Mus musculus) re-invaded, providing an opportunity to investigate their impact on L. hamiltoni. In Phase I, 60 frogs were translocated into mouse-proof enclosures over 2006–2007.

Post-metamorphic body growth and longevity of two archaic terrestrial frogs (Anura: Leiopelmatidae) endemic to New Zealand are described using data from long-term capture-recapture studies and measurements of snout-vent length. Population studies of Hamilton's frog (Leiopelma hamiltoni) on Te Pākeka/Maud Island, Marlborough Sounds, have been undertaken since 1976 and Archey's frog (L. archeyi) in the Coromandel Ranges since 1982.
