IUCN-CI Biodiversity Assessment Unit

 The IUCN-CI Biodiversity Assessment Unit (BAU) established in 2001, is a collaborative project between IUCN and Conservation International with the mandate of expanding the taxonomic and geographic coverage of the IUCN Red List.

Since inception, the BAU, working in close association with the IUCN Species Programme and other partners, has conducted: the first-ever assessment of the world’s 6,000 amphibians (the Global Amphibian Assessment or GAA); a major revision of the conservation status of the world’s mammals (Global Mammal Assessment, or GMA); initiated a comprehensive assessment of some 20,000 selected marine species (the Global Marine Species Assessment, or GMSA) and some 9,000 reptiles (the Global Reptile Assessment, or GRA); and raised more than US$500,000 in funding to support the Global Freshwater Biodiversity Assessment. Most recently the BAU has additionally supported a review of the conservation status of the world’s cacti species (Global Cactus Assessment).

The assessment process typically includes the organization of regional workshops, attended by the world’s leading experts, on particular species groups. Scientifically rigorous data are collected on the geographic range of the species (including a range map); population status; habitat and ecology; threats to the species; conservation measures needed and in place; and finally, once the supporting information is available, the allocation of a standardized IUCN Red List Category indicating the degree of extinction risk.

All of the data collected during the assessment process are made publically available on the IUCN Red List website.

The comprehensive information gathered can be used to inform the planning of individual species conservation efforts (such as the development of action plans); to identify sites for conservation action (such as the designation of protected areas); to inform broader policy and management (at scales from local to international level); to evaluate the state of biodiversity (allowing geographic and taxonomic comparisons); and to monitor the changing state of biodiversity (including the Red List Index).

Global appetite for resources pushing new species to the brink – IUCN Red List

Pacific Bluefin Tuna, Chinese Pufferfish, American Eel, Chinese Cobra and an Australian butterfly are threatened with extinction

Fishing, logging, mining, agriculture and other activities to satisfy our growing appetite for resources are threatening the survival of the Pacific Bluefin Tuna, Chinese Pufferfish, American Eel and Chinese Cobra, while the destruction of habitat has caused the extinction of a Malaysian mollusc and the world’s largest known earwig, and threatens the survival of many other species – according to the latest update of the IUCN Red List of Threatened Species™ released today at the IUCN World Parks Congress taking place in Sydney, Australia. …   | French | Spanish | Dutch

Documentation and Analysis of NBSAP Revision Processes

National Biodiversity Strategies and Action Plans (NBSAPs) are the main vehicles of national implementation of the Convention on Biological Diversity. They are processes through which societies come together to make the difficult decisions of where, when, and how biodiversity and ecosystem services should be conserved, used sustainably, and the benefits of this use shared equitably. Most countries that are Parties to the Convention have already developed at least one NBSAP. …
