The latest update of the IUCN Red List of Threatened Species shows that more than a third of species (17,291 species out of the 47,677 assessed species) are threatened with extinction. A fifth of the world's known mammals, a third of its amphibians, more than a quarter of its reptiles and up to 70% of its plants are under threat of extinction according to the red list of threatened species, the latest survey compiled by the International Union for Conservation of Nature (IUCN). "The scientific evidence of a serious extinction crisis is mounting," says Jane Smart, Director of IUCN's Biodiversity Conservation Group. "January sees the launch of the International Year of Biodiversity. The latest analysis of the IUCN Red List shows the 2010 target to reduce biodiversity loss will not be met. It's time for governments to start getting serious about saving species and make sure it's high on their agendas for next year, as we're rapidly running out of time." The Eastern Voalavo (Voalavo antsahabensis) appears on the IUCN Red List for the first time in the Endangered category. This rodent, endemic to Madagascar, is confined to montane tropical forest and is under threat from slash-and-burn farming. Among the critically endangered species are the western lowland gorilla and the bactrian camel. The golden-headed lion tamarin is listed as endangered and the socorro dove is extinct in the wild. Only a single male specimen of the Rabb's fringe-limbed tree frog, which lives in central Panama, has been heard calling in the last three years and attempts to breed it in captivity have so far failed.
