The 2007 IUCN Red List has been issued, and the news is grim. Extinction crisis escalates: Red List shows apes, corals, vultures, dolphins all in danger 2007 IUCN Red List of Threatened Species™, the world’s most authoritative assessment of the Earth’s plants and animals, acts as a wake up call on the global extinction crisis 74 seaweeds have been added to the IUCN Red List from the Galápagos Islands. Ten species are listed as Critically Endangered, with six of those highlighted as Possibly Extinct. The cold water species are threatened by climate change and the rise in sea temperature that characterizes El Niño. The seaweeds are also indirectly affected by overfishing, which removes predators from the food chain, resulting in an increase of sea urchins and other herbivores that overgraze these algae. Yangtze River Dolphin listed as Critically Endangered (Possibly Extinct) After an intensive, but fruitless, search for the Yangtze River Dolphin, or Baiji, (Lipotes vexillifer) last November and December, it has been listed as Critically Endangered (Possibly Extinct). The dolphin has not been placed in a higher category as further surveys are needed before it can be definitively classified as Extinct. A possible sighting reported in late August 2007 is currently being investigated by Chinese scientists. The main threats to the species include fishing, river traffic, pollution and degradation of habitat. India and Nepal’s crocodile, the Gharial (Gavialis gangeticus) is also facing threats from habitat degradation and has moved from Endangered to Critically Endangered. Its population has recently declined by 58%, from 436 breeding adults in 1997 to just 182 in 2006. Dams, irrigation projects, sand mining and artificial embankments have all encroached on its habitat, reducing its domain to 2% of its former range. Banggai Cardinalfish heavily exploited by aquarium trade Overfishing continues to put pressure on many fish species, as does demand from the aquarium trade. The Banggai Cardinalfish (Pterapogon kauderni), which is highly prized in the aquarium industry, is entering the IUCN Red List for the first time in the Endangered category. The fish, which is only found in the Banggai Archipelago, near Sulawesi, Indonesia, has been heavily exploited, with approximately 900,000 extracted every year. Conservationists are calling for the fish to be reared in captivity for the aquarium trade, so the wild populations can be left to recover. These highlights from the 2007 IUCN Red List are merely a few examples of the rapid rate of biodiversity loss around the world. The disappearance of species has a direct impact on people’s lives. Declining numbers of freshwater fish, for example, deprive rural poor communities not only of their major source of food, but of their livelihoods as well.

It is a searchable online database containing the global status and supporting information on more than 41,000 species. Its primary goal is to identify and document the species most in need of conservation attention and provide an index of the state of biodiversity. The IUCN Red List threat categories are the following, in descending order of threat: Extinct or Extinct in the Wild; Critically Endangered, Endangered and Vulnerable: species threatened with global extinction; Near Threatened: species close to the threatened thresholds or that would be threatened without ongoing specific conservation measures; Least Concern: species evaluated with a low risk of extinction; Data Deficient: no evaluation because of insufficient data. Critically Endangered (Possibly Extinct): This is not a new Red List category, but is a flag developed to identify those Critically Endangered species that are in all probability already Extinct but for which confirmation is required (for example, through more extensive surveys being carried out and failing to find any individuals). The total number of species on the planet is unknown; estimates vary between 10 - 100 million, with 15 million species being the most widely accepted figure. 1.7 - 1.8 million species are known today. People, either directly or indirectly, are the main reason for most species’ decline. Habitat destruction and degradation continues to be the main cause of species’ decline, along with the all too familiar threats of introduced invasive species, unsustainable harvesting, over-hunting, pollution and disease. Climate change is increasingly recognized as a serious threat, which can magnify these dangers. Major analyses of the IUCN Red List are produced every four years. These were produced in 1996, 2000 and 2004. The 2004 Global Species Assessment is available from: http://www.iucn.org/themes/ssc/ red_list_2004/2004home.htm Key findings from major analyses to date include: The number of threatened species is increasing across almost all the major taxonomic groups. IUCN Red List Indices, a new tool for measuring trends in extinction risk are important for monitoring progress towards the 2010 target. They are available for birds and amphibians and show that their status has declined steadily since the 1980s. An IUCN Red List Index can be calculated for any group which has been assessed at least twice. Most threatened birds, mammals and amphibians are located on the tropical continents – the regions that contain the tropical broadleaf forests which are believed to harbour the majority of the Earth’s terrestrial and freshwater species. Of the countries assessed, Australia, Brazil, China and Mexico hold particularly large numbers of threatened species. Estimates vary greatly, but current extinction rates are at least 100-1,000 times higher than natural background rates. The vast majority of extinctions since 1500 AD have occurred on oceanic islands, but over the last 20 years, continental extinctions have become as common as island extinctions. All IUCN Red List updates contribute to a worldwide biodiversity assessment. Work is underway to reassess the status of all mammals (approximately 6,000 species) and birds (approximately 10,000 species) and to assess for the first time all reptiles (approximately 8,000 species) and freshwater fish (approximately 13,000 species). The first global assessment of all amphibians (approximately 6,000 species) was completed in 2004. The IUCN Red List of Threatened Species™ is a joint effort between IUCN and its Species Survival Commission www.iucn.org/themes/ssc, working with its Red List partners BirdLife International www.birdlife.org, Conservation International’s Center for Applied Biodiversity Science www.conservation.org, NatureServe www.natureserve.org, and the Zoological Society of London www.zsl.org. About The World Conservation (IUCN) Created in 1948, the World Conservation Union (IUCN) brings together 84 States, 108 government agencies, 800 plus NGOs, and some 10,000 scientists and experts from 147 countries in a unique worldwide partnership. The Union’s mission is to influence, encourage and assist societies throughout the world to conserve the integrity and diversity of nature and to ensure that any use of natural resources is equitable and ecologically sustainable. The Union is the world's largest environmental knowledge network and has helped over 75 countries to prepare and implement national conservation and biodiversity strategies. The Union is a multicultural, multilingual organization with 1,000 staff located in 62 countries. Its headquarters are in Gland, Switzerland. www.iucn.org About the IUCN Species Survival Commission (SSC) and Species Programme The Species Survival Commission (SSC) is the largest of IUCN’s six volunteer commissions with a global membership of 7,000 experts. SSC advises IUCN and its members on the wide range of technical and scientific aspects of species conservation and is dedicated to securing a future for biodiversity. SSC has significant input into the international agreements dealing with biodiversity conservation. www.iucn.org/themes/ssc/ The IUCN Species Programme supports the activities of the IUCN Species Survival Commission and individual Specialist Groups, as well as implementing global species conservation initiatives. It is an integral part of the IUCN Secretariat and is managed from IUCN’s international headquarters in Gland, Switzerland. The Species Programme includes a number of technical units covering Species Trade and Use, the Red List Unit, Freshwater Biodiversity Assessments Unit, (all located in Cambridge, UK), and the Global Biodiversity Assessment Unit (located in Washington DC, USA).
