Life on Earth is under serious threat, despite the commitment by world leaders to reverse the trend, according to a detailed analysis of the IUCN Red List of Threatened Species™.

The IUCN analysis, which is published every four years, comes just before the deadline governments set themselves to evaluate how successful they were in achieving the 2010 target to reduce biodiversity loss. The IUCN report, Wildlife in a Changing World, shows the 2010 target will not be met.

"When governments take action to reduce biodiversity loss there are some conservation successes, but we are still a long way from reversing the trend,” says Jean-Christophe Vié, Deputy Head of IUCN’s Species Programme and senior editor of the publication. “It’s time to recognize that nature is the largest company on Earth working for the benefit of 100 percent of humankind – and it's doing it for free. Governments should put as much effort, if not more, into saving nature as they do into saving economic and financial sectors."

The report analyses 44,838 species on the IUCN Red List and presents results by groups of species, geographical regions, and different habitats, such as marine, freshwater and terrestrial.

The first study to determine the global conservation status of 64 species of open ocean (pelagic) sharks and rays reveals that 32 percent are threatened with extinction, primarily due to overfishing, according to the IUCN Shark Specialist Group.

The percentage of open ocean shark species threatened with extinction is higher for the sharks taken in high-seas fisheries (52 percent), than for the group as a whole.

"Despite mounting threats, sharks remain virtually unprotected on the high seas," says Sonja Fordham, Deputy Chair of the IUCN Shark Specialist Group and Policy Director for the Shark Alliance. "The vulnerability and lengthy migrations of most open ocean sharks mean they need coordinated, international conservation plans. Our report documents serious overfishing of these species, in national and international waters, and demonstrates a clear need for immediate action on a global scale."

The report comes days before Spain hosts an international summit of fishery managers responsible for high seas tuna fisheries in which sharks are taken without limit. It also coincides with an international group of scientists meeting in Denmark to formulate management advice for Atlantic porbeagle sharks.

According to a new publication by Wetlands International, more than half the populations of waders in Europe, West Asia and Africa are declining at an accelerating rate.

Waders are a group of relatively small waterbirds including species like lapwings, plovers, godwits, curlews and sandpipers. Many of them undertake long distance migrations from their Arctic breeding grounds to wintering areas as far away as southern Africa. Some concentrate in huge numbers at just a few sites, making these wetlands critical for their survival.

The new 'Wader Atlas' is the first comprehensive overview of key site networks for waders in Europe, West Asia and Africa, and the publication highlights a need for better protection of the key wetlands along their flyways, especially in Africa and the Middle East.

The authors outline that whilst many European Union (EU) Member States have established a fairly comprehensive network of protected areas for waders, many of which are Important Bird Areas (IBAs) identified by the BirdLife Partnership, the protection and management of key sites is still far from adequate beyond the EU's borders.
