Applies Red List data to calculate a Red List Index.

Release of the 2000 Red List is a major landmark for IUCN. It is the first time that listings of animals and plants have been combined and the first time that the Red List has been produced on CD-ROM. The 2000 Red List combines new assessmentsincluding all bird species, many antelope and bat species, most primates and sharks, all Asian freshwater turtles, more molluscs, and many otherswith those from previous publications. The combination of animals and plants into a single list containing assessments of more than 18,000 taxa (11,000 of which are threatened species) and the move towards improved documentation of each species on the list means that a hard-copy version of the Red List would run to several volumes. This, combined with the fact that the Red List will be updated annually, led to the decision to release the Red List in electronic format, via the World Wide Web and as a CD-ROM.

"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."

Tree species are ecologically, culturally and economically valuable components of biodiversity and their conservation is essential to the well-being of people in all countries of the world. With increasing general pressures on ecosystems and selective pressures on species, it has become apparent that many tree species are threatened with extinction. The world list of threatened trees presents the results of the first survey of the conservation status of tree species worldwide.

"Amphibians are facing an extinction crisis, but getting to the facts has been difficult. "Threatened Amphibians of the World" is a visual journey through the first-ever comprehensive assessment of the conservation status of the world's 6,000 known species of frogs, toads, salamanders, and caecilians. All 1,900 species known to be threatened with extinction are covered, including a description of threats to each species and an evaluation of conservation measures in place or needed. Each entry includes a photograph or illustration of the species where available, a distribution map, and detailed information on range, population and habitat and ecology. Introductory chapters present a detailed analysis of the results, complemented by a series of short essays written by many of the world's leading herpetologists. Appendices include annoted lists of lower risk species and a country-by-country listing of threatened amphibians."--pub. desc.
