Prehistoric frogs face extinction
Thursday 20 May 2010
The world’s most ancient frogs may soon be mined to extinction, if the New Zealand government’s plans to open up a
conservation area for mining go ahead.
The primitive Archey’s frog (Leiopelma archeyi) and Hochstetter’s frog (Leiopelma hochstetteri) are two of the species
that inhabit the area of ‘high conservation value’ on New Zealand’s North Island where the mining is planned to take
place.
Archey’s frog is currently ranked top of ZSL's EDGE of Existence amphibian list, making it the most evolutionarily
distinct and globally endangered amphibian on the planet. Described as a “living fossil”, Archey’s frog is almost
indistinguishable from the fossilised remains of frogs that walked amongst the dinosaurs 150 million years ago.
“In the year when reducing biodiversity loss is high on the political agenda, it is inconceivable to think that we’d put
the nail in the coffin of some of our rarest and most extraordinary frog species,” say Helen Meredith, EDGE of Existence
amphibian conservation projects coordinator at ZSL.
She adds: “We will be faced with these kinds of decisions again and again in the future. Now is the time to start
recognising the long-term value of our natural world over any short-term economic gains.”
The frog populations have been intensively monitored for over 40yrs, representing the best data set on frog populations
in the world. The proposed mining will cut through the heart of these monitoring sites.
Dr Phil Bishop, leader of the University of Otago’s frog research says “Only four species of frog survive in New
Zealand, and this proposed mining activity could cause the extinction of one of New Zealand’s native amphibians, and a
severe decline in another - a devastating blow to global amphibian conservation.”
7,000 hectares of land in the West Coast’s Paparoa National Park, Great Barrier Island and the Coromandel Peninsula has
been proposed to be considered for mining of coal, gold, iron ore and other rare minerals.
The North Island brown kiwi, long-tailed bats, striped geckos and Helm’s butterfly are some of the other rare and
endangered species found in these protected areas.
The New Zealand government is now holding a public consultation on whether the conservation status of the area should be
downgraded to allow mining to take place. The closing date for submissions is Thursday 26 May 2010.
ZSL conservationists are now calling for UK residents to support the protection of New Zealand’s unique flora and fauna
by submitting to the public consultation process.
