A study in 1990–1993 of endangered Hamilton's frog Leiopelma hamiltoni on Stephens Island, New Zealand (Brown 1994) found that at least seven of 12 translocated frogs survived the first year within a predator-proof exclosure. The seven frogs were recaptured 27 times by June 1993. There was no control and so the frogs may have survived without the exclosure. In May 1992, frogs were translocated 40 m to a new habitat (a rock-filled pit 72 m2) created in May-October 1991 in a nearby forest remnant. A predator-proof fence was built around the new habitat to exclude tuatara Sphenodon punctatus and the area was ‘seeded’ with invertebrate prey. Frogs were surveyed regularly from November 1990 to May 1992 (90 visits).
