Rescued ploughshare tortoises start first European breeding programme26/08/2012 10:13:12
Ploughshare tortoisesSafety net population to ensure Ploughshare survival
The ploughshare tortoise (Astrochelys yniphora) is one of 4 highly threatened Madagascan chelonian species, which also include the radiated tortoise (Astrochelys radiata), flat-tailed tortoise (Pyxis planicauda) and the spider tortoise (Pyxis arachnoides).
Restricted to the bamboo scrub dry forest of North West Madagascar, the entire known range of the ploughshare is within the Baly Bay National Park. Previously the main threat to the tortoise came through habitat loss and degradation from cattle encroachment and burning. But now the leading cause of their decline is the illegal harvesting for the international pet trade. As one of the rarest tortoises in the world, this species can command high values on the black market.
Durrell leads conservation efforts for the ploughshare tortoise in Madagascar; working with government authorities and international partners to manage and protect their remaining habitat in Baly Bay National Park; local communities to reduce pressures on the species and managing a captive breeding and reintroduction programme which has released 65 animals back to the wild. Earlier in 2012, the first babies of released animals were discovered in the wild showing that the release programme is being successful.
August 2012. Conservationists are launching the first European breeding programme for ploughshare tortoises in an attempt to create a vital safety net population of the Critically Endangered animals.
Ploughshare tortoises are already being kept in captivity in America, where 20 animals are registered within three institutions, but it is the first time that they are being coordinated to form a breeding population in Europe. It follows a boom in the Asian pet trade, where ploughshares are being sold illegally for high prices, raising further concern for the future of the species.
The ploughshare tortoise is one of the most threatened species on the planet and until now, conservation efforts have focused on saving the species in its home range in Madagascar and protecting its native habitat, where Durrell began working with the species in 1986.
13 tortoises seized in Hong Kong
Matthias Goetz, Head of Durrell's Herpetology Department, said: "Thankfully the rescued tortoises were given to the Kadoorie Farm and Botanical Garden (KFBG) wild animal rescue centre, which took great care of them and started working with international partners to identify new homes for the animals. Along with the other two European institutions, Durrell is delighted to be receiving some of the tortoises and playing a part in a new captive breeding programme which aims to save these beautiful creatures from extinction."
Illegal pet trade
Matthias said: "Sadly, an increasing number of animals have been smuggled out of Madagascar through South Asian countries where more and more have been seized by border authorities. While it has been possible to repatriate some, this is challenging and if the animals have spent time outside of Madagascar there are disease risks to bringing them back. Equally, establishing a viable international breeding programme for the species has been identified as one of the key approaches to ensuring the species' survival."
The European breeding programme will now work alongside the one in America and the dedicated conservation actions in Madagascar. However, Dr Gerardo Garcia, Curator of Lower Vertebrates and Invertebrates for Chester Zoo, stressed that they would have to be patient while waiting for results from the new arrivals.
He explained: "As with all things associated with tortoises, it will take a while before these animals are ready to breed. They are only young and it will take a few years for them to reach maturity. But what is important is that the European breeding programme has now started and in the future, seized ploughshare tortoises will form part of an international safety net population, should the worst happen to the remaining tortoises in Madagascar."
