World’s largest conservation gathering opens to escalating global species extinction crisis

A total of 15,589 species face extinction, reveals the 2004 IUCN Red List of Threatened Species. One in three amphibians and almost half of all freshwater turtles are threatened, on top of the one in eight birds and one in four mammals known to be in jeopardy.

Pittosporum tanianum was first discovered in 1988 in New Caledonia. It was thought to have become Extinct in 1992, but in 2002 it was rediscovered and is now listed as critically Endangered. Three plants are now known to exist, giving this species a tenuous lifeline to avoid extinction. Loss and degradation of its sclerophyllous forest habitat is the main threat to the species - photo © Bernard SuprinBangkok, Thailand, 17 November 2004. IUCN-The World Conservation Union- From the mighty shark to the humble frog, the world’s biodiversity is declining at unprecedented rates. Halting the growing extinction crisis will be a major concern for IUCN’s 1,000 plus member organisations attending the 3rd IUCN World Conservation Congress, which kicks off in Bangkok today.

The situation facing global biodiversity is clearly escalating and the 4,000 delegates, including representatives of the private sector, governmental and non-governmental organisations, will be outlining ways to halt this alarming trend. They will draw the attention of the international community to the fact that species loss has critical implications for human well-being, and that conserving biodiversity is central to managing the risks this poses to sustainable development.

There is some good news. Conservation measures are already making a difference – a quarter of the world’s threatened birds have benefited from such measures. What is needed is more of them, and to focus them better using the constantly improving information at our disposal. That means more resources, resources applied more effectively, and new coalitions across all sections of society.

Nectophrynoides viviparus is one of the few frogs that give birth to live young. This Vulnerable species occurs in the Uluguru and Udzungwa Mountains and in the Southern Highlands of Tanzania. It is threatened by ongoing forest loss, especially at lower altitudes, due to agricultural encroachment, wood extraction and expanding human settlements - photo © David Moyer ? Wildlife Conservation SocietyThese are among the key messages to emerge from the Global Species Assessment (GSA) based on, and released in conjunction with, the 2004 IUCN Red List of Threatened Species. It is the most comprehensive evaluation ever undertaken of the status of the world’s biodiversity. The GSA is produced by the Red List Consortium comprising IUCN and its Species Survival Commission, Conservation International and its Center for Applied Biodiversity Science, BirdLife International and NatureServe.

The Global Species Assessment shows trends in biodiversity over four years since the last major analysis in 2000, and it includes, for the first time, complete assessments of amphibians, cycads (an ancient group of plants) and conifers, as well as regional case studies. It also highlights which species are at greatest risk of extinction, where they occur, and the many threats facing them. more

Case Studies
Threats
This section deals with threats to species due to, among others, over-fishing and climate change. more
Extinctions
Examples of extinctions including amphibians, molluscs, and the St. Helena olive. more
Conservation Success
Case studies covering conservation successes through, for example, re-introduction, captive breeding, environmental education, and habitat restoration. more

Slender loris (Loris tardigradus) from Sri Lanka is assessed as Endangered. Habitat fragmentation over the years has seriously reduced the area available for this species. Between 1956 and 1993, Sri Lanka lost more than 50% of forest cover to human activities, followed by a similar rate of decline in the remaining forest cover between 1994 and 2003 - photo © Anna Nekaris A gallery of images is available on the 2004 IUCN Red List website. more photos

Species Profiles
The St. Helena olive (Nesiota elliptica) (Extinct) became Extinct in the Wild in 1994 and all attempts to propagate and maintain the species ex situ failed, with the last individual dying in December 2003 - photo © Rebecca Cairns-Wicks St. Helena olive
Profiled in the release of the 2003 IUCN Red List as Extinct in the Wild, this symbolic species is now sadly Extinct. more
The Hawaiian crow (Corvus hawaiiensis) is now listed as Extinct in the Wild after the last two known wild individuals disappeared from Hawaii in 2002. Habitat alteration, collecting and shooting, introduced predators (e.g., rats, the Indian mongoose) and predation from the native Hawaiian hawk, and avian malaria and pox carried by introduced mosquitoes have contributed to the crow?s decline. Some individuals remain in captive breeding facilities and a reintroduction plan is being developed - photo © Jack Jeffrey Photography Hawaiian crow
Moving from Critically Endangered to Extinct in the Wild, the last two known wild individuals of this species disappeared in 2002. more
Humphead wrasse (Cheilinus undulatus) is widely distributed on coral reefs and inshore habitats throughout much of the tropical Indo-Pacific, but it is nowhere common. Wherever it is fished, even if only moderately, density quickly declines and it appears now to have disappeared from several locations. It is particularly heavily exploited at the centre of its range in southeastern Asia for the live reef fish trade. Fishery-dependent and trade-related data suggest overall declines of at least 50% over the last 30 years - photo © John E. Randall Humphead wrasse In 1996, the humphead wrasse was assessed as Vulnerable. more
The fabulous green sphinx moth (Tinostoma smaragditis) was listed as Extinct in 1996, but in February 1998 a single male was attracted to a light trap on its home island of Kauai, Hawaii. Since 1998, further individuals have been trapped, but the species is listed as Endangered due to the impacts of invasive species on its habitat - photo © Mandy Heddle Fabulous green sphinx moth
This enthusiastically named species moved from Data Deficient to Endangered. more
