Braunschweig, 11 August 2014 \u2013 Reptiles are among Madagascar’s most bewildering creatures, but nearly 40% of them are facing an elevated risk of extinction according to a study published today by an international team of researchers with participation of a German team of specialists. Forest clearance threatens the island’s snakes and lizards, whilst illegal collecting for trade and consumption heavily affects tortoises and turtles. Yet, almost of the over 370 known species have been observed recently in the wild, suggesting that few extinctions have occurred yet and that urgent and intensive conservation actions might still be able to save these unique animals. dx.plos.org\/10.1371\/journal.pone.0100173<\/a><\/p>\n

Madagascar is renowned for its unique animals and plants, most of which occur nowhere else on Earth. Few tourists leave the island without being astonished by a glimpse of its colourful chameleons, giant snakes and otherworldly leaf-tail geckos.<\/p>\n

But the island is also a priority country for nature conservation. Most of Madagascar’s wildlife, including the well-known lemurs, is affected by habitat destruction and over-collecting.<\/p>\n

An assessment of the extinction risk of Madagascar’s over 370 species of native reptiles has now been completed by national and international experts for The Red List of Threatened Species of the International Union for Conservation of Nature (IUCN). Today, in a research paper entitled \u2018Extinction Risk and the Conservation of Madagascar\u2019s Reptiles\u2019, the authors analysed patterns in the geographic distribution of the species and the threats facing them.<\/p>\n

The data suggest that as many as 39% of Madagascar’s reptile species are threatened with extinction. Clearance, or disturbance, of forest habitats for timber removal and expanding agriculture is the major threat to Madagascar\u2019s snakes and lizards, including chameleons and geckos. All Malagasy species of tortoises and freshwater turtles were classed as \u2018Critically Endangered\u2019, because of escalating levels of illegal collection for international trade and human consumption.<\/p>\n

Such new information on the status of reptiles in Madagascar is crucial to evaluating the exact role of existing protected areas as well as for prioritizing funding and conservation action.<\/p>\n

Most importantly, the study also gives some reason for optimism. In fact, no extinctions have so far been documented \u2013 with almost all known species having been recorded in recent years in the wild. And most of them occur within the protected area network, although threats are active even in many protected sites, calling for their improved conservation.<\/p>\n

Miguel Vences, a Madagascar reptile specialist from the University of Braunschweig in Germany, notes: “Our results highlight the importance of Madagascar\u2019s new protected areas, created since 2003. And, given that almost no extinctions have been recorded yet, we still have the chance to save Madagascar’s unique reptiles from extinction.”<\/p>\n
