Nearly one in five of the world’s estimated 10,000 species of lizards, snakes, turtles, crocodiles and other reptiles are threatened with extinction, according to a study conducted by 200 experts.
But the risk of extinction was found to be unevenly spread throughout the extremely diverse group of animals. According to the paper, an alarming 50% of all freshwater turtles are close to extinction, possibly because they are traded on international markets.
The study, published by the Zoological Society of London in conjunction with the IUCN species survival commission, is the first of its kind summarising the global conservation status of reptiles, and used 1,500 randomly selected reptiles worldwide.
Out of the estimated 19% of reptiles threatened with extinction, in order of magnitude of danger, 12% are classified as critically endangered, 41% endangered and 47% vulnerable.
Three species were found to be possibly extinct. One, a jungle runner lizard, Ameiva vittata, has only ever been recorded in one part of Bolivia. In Haiti, six of the nine species of anolis lizard included in this study have an elevated risk of extinction, due to extensive deforestation affecting the country.
The spread of farming and deforestation in tropical regions represents two of the greatest threats to reptiles, says the paper.
