Launch for amphibian 'life raft'

 Dendrobates azureus - R.A.Mittermeier

By Richard Black, Environment correspondent, BBC News website

Conservationists have launched a new initiative aimed at safeguarding the world's amphibians from extinction.

The Amphibian Survival Alliance will bring together existing projects and organisations, improving co-ordination, scientific research and fund-raising.

About a third of amphibian species are threatened with extinctions.

A two-day summit held last week in London identified the two main threats as destruction of habitat and the fungal disease chytridiomycosis.

"The world's amphibians are facing an uphill battle for survival," said James Collins, co-chair of the Amphibian Specialist Group (ASG) co-ordinated by the International Union for the Conservation of Nature (IUCN).

"By far the worst threats are infectious disease and habitat destruction, so the Alliance will focus on these issues first." ...

"If we want to stop the amphibian extinction crisis, we have to protect the areas where amphibians are threatened by habitat destruction," said Claude Gascon, the Amphibian Specialist Group's other co-chair.

"One of the reasons amphibians are in such dire straits is because many species are only found in single sites and are therefore much more susceptible to habitat loss." …

The 'mountain chicken' frog

By Jessica Aldred and agencies

Conservationists have rescued a number of critically endangered "mountain chicken" frogs from the path of a fatal disease which has hit their Caribbean island home of Montserrat.

The decision to remove 50 mountain chicken frogs (leptodactylus fallax) from their natural habitat was taken in the face of the spread of the chytrid fungus, which is devastating amphibian populations worldwide.

The Zoological Society London (ZSL) and the Durrell Wildlife Conservation Trust, based in Jersey, have each provided a home for 12 of the frogs which have been removed from Montserrat. Another 26 have gone to Parken zoo in Stockholm.

The plan is to breed the rescued frogs in captivity in a bid to save the species from extinction.

Montserrat is one of only two sites where the once-common mountain chicken is found, but hundreds of the frogs - one of the world's largest species - have been killed in the last few weeks by the disease. …

Dr Andrew Cunningham, a senior ZSL scientist, said: "Chytridiomycosis has already decimated the mountain chickens on Dominica and within a few weeks of the disease being diagnosed on the neighbouring island of Montserrat, its impact has been catastrophic. The mountain chicken frog has been virtually wiped out on the island and the number of surviving frogs decreases every day." …
