Who will help them against mankind’s destruction of their habitat if zoos don’t? Conservationsists race to halt decline of some of the planet’s best-loved animal species

One of the world’s largest frogs, Britain’s only native crayfish and Amur leopards are among the creatures fighting extinction with the help of caring zoos.
A list of species whose future is most reliant on conservation programmes has been drawn up by the British and Irish Association of Zoos and Aquariums to highlight their work to save wildlife.
The top 10 list includes Polynesian tree snails, the Potosi pupfish from Mexico and the Scimitar-horned oryx from Tunisia, Morocco and Senegal, which are all extinct in the wild.
The critically endangered mountain chicken frog, facing extinction in its Caribbean home from exploitation by humans, habitat loss and a deadly fungus, is being bred in captivity in the UK.
Just 45 Amur leopards remain in the wild but there are 220 of the critically endangered cat in a global conservation breeding programmes in zoos around the world with a reintroduction scheme that is currently in the planning stages.
Around 95 per cent of Britain’s white-clawed crayfish have vanished from the country as a result of the introduction of American signal crayfish and disease, prompting UK zoos to breed the species for release in safe areas in the wild and raise public awareness of their plight.
The top 10 list also includes ploughshare tortoises and the blue-eyed black lemur, which are both from Madagascar.
Zoos are also helping the blue-crowned laughingthrush, whose population numbers less than 250 mature birds in the wild in China, and even a tree, the Verdcourt’s polyalthia, which is found in just three places in the Kilombero valley of Tanzania.
Andrew Marshall, of the association’s programmes committee, said: “This list highlights 10 prevailing examples of how zoos are working to save these and many other species from extinction.
“Without the valuable conservation and breeding work of many of our member zoos and aquariums, at-risk species such as these may be lost to extinction forever.”
The top 10 were chosen from hundreds of zoo-backed conservation programmes, focusing on species at high risk of extinction or extinct in the wild, schemes which involved initiatives in the field, zoos which had a management role and projects which included habitat protection and working with local communities.
