Archey's frog (Leiopelma archeyi) is an archaic species of frog endemic to the North Island of New Zealand. It is one of only three extant species belonging to the taxonomic family Leiopelmatidae. It is named after Sir Gilbert Archey, the former director of the Auckland Institute. The holotype is held at the Auckland War Memorial Museum. It is found only in the Coromandel Peninsula and near Te Kuiti in the North Island of New Zealand. This species, along with others in the family, have changed little over the past 200 million years, thus they represent "living fossils". Ecology The species is fully terrestrial, living and reproducing under damp vegetation in native forests. Currently, its distribution is confined to higher elevations at just two localities, although just 25 years ago, the species was abundant in a much wider range, down to sea level. Little is known about the natural history of this species. Although the species is sexually monomorphic, males are believed to be the primary care providers, and may prepare "nests" they guard for the eggs, secreting antimicrobial peptides onto them, to ensure successful embryonic development. Clutch sizes vary between four and 15 eggs. Reproduction is fully terrestrial; tadpoles develop within gelatinous egg capsules, and upon hatching, tailed froglets crawl onto the male's back and are carried around for several weeks where they complete metamorphosis. Adult frogs do not give advertisement vocalisations, but may communicate by chemical signalling. However, frogs sometimes give startle calls when threatened by a predator. Conservation An intensively monitored population in one Cormandel site declined by 88% from 1996 to 2001, but in many areas where frogs previously were common, none remain. Because populations are rapidly declining, and reproduction is infrequent, the species is at significant risk of imminent extinction. In 2006 70 Archey's frogs were translocated to Pureora Forest however despite breeding being observed only low numbers of frogs have been counted. As first shown by Bruce Waldman, the species appears to have an intrinsically low level of susceptibility to chytridiomycosis. However, frogs in the field show clinical signs, including blisters, that may be associated with other diseases. Nonetheless, despite field observations suggesting that frogs were dying from other causes, New Zealand researchers continued to argue that the species was most at risk from chytridiomycosis and planned their management strategies primarily to mitigate threats from this disease.
