The International Union for Conservation of Nature (IUCN) updated its authoritative study on the state of biodiversity on Earth, saying 20,219 species were at risk of dying out.
It added 402 species such as the Egyptian dab lizard and the Sichuan Taimen, a fresh water fish from China, to the “Red List”, which puts them in the threatened category.
Two invertebrates, a cockroach from the Seychelles last seen in 1905 and a freshwater snail called Little Flat-Top from the US state of Alabama, have moved into the extinct category since the last update of the bi-annual survey in June.
“These are species that do not occur anywhere else in the world,” the IUCN’s director of biodiversity conservation Jane Smart said at a UN Convention on Biological Diversity (CBD) conference in Hyderabad, southern India.
The report also showed that 83 percent of Madagascar’s 192 palm species, which the poor rely on heavily for food and housing, are at risk of extinction.
They include the “Suicide Palm”, which grows up to 18 metres (60 feet) in height and dies a few months after flowering and producing seeds. Only 30 mature specimens are known to exist in the wild today.
A quarter of the world’s mammals, 13 percent of birds, 41 percent of amphibians and 33 percent of reef-building corals are at risk of extinction, according to the IUCN.
The report set alarm bells ringing as more than 70 environment ministers met for talks on halting the depletion of the Earth’s natural resources, with pressure for them to match political pledges with hard cash.
There was also some happy news, however, with the IUCN saying eight species had moved out of the extinct category due to new sightings.
They include a Tanzanian tree, Erythrina schliebenii, five types of mollusc, a dwarf toad from Sri Lanka, and Holdridge’s Toad, a species from Costa Rica.
The gathering comes two years after UN countries approved a 20-point plan at a conference in Japan for reversing the worrying decline in plant and animal species that humans depend on for food, shelter and livelihoods.
Execution of the plan has been hamstrung by a lack of funding and the Hyderabad talks are being closely watched for new financial commitments.
