Le but de cette évaluation est de rassembler des informations sur les caméléons dont la situation est préoccupante en raison des volumes atteints récemment par le commerce à partir d'études réalisées sur le terrain.
This review of the European bisons (Bison bonasus) status clearly indicates that, through proper management and conservation, its present numbers and distribution have improved significantly since its extinction in the wild at the beginning of the 20th century. The Action Plan briefly summarizes the history of extinction in the wild and present status of the European bison, as well as the reasons of extinction.
The new Canid Action Plan synthesizes the current knowledge on the biology, ecology and status of all wild canid species, and outlines the conservation actions and projects needed to secure their long-term survival.
Les chimpanzés vivent à létat sauvage uniquement en Afrique tropicale où leur population a diminué de plus de 66% au cours des trente dernières années. Ce plan daction concerne lune des quatre sous-espèces de chimpanzés, le chimpanzé dAfrique occidentale, qui est lune des deux sous-espèces les plus menacées dextinction.
Wild chimpanzees are only found in tropical Africa, where their populations have declined by more than 66% in the last 30 years. This action plan focuses on one of the four chimpanzee subspecies, the western chimpanzee, which is one of the two subspecies most threatened with extinction.
The African elephant is the largest living land mammal, and their potential impact on their habitats raises important management issues both for protected areas and unprotected land. This Status Report, derived from data contained in the African Elephant Database, is rich in data and information on numbers, distribution and current issues, and provides continent-wide information that is vital for conservation.
The rationale for this three-volume work covering nearly 250 major sites for conservation of plant diversity worldwide is concern about rapid global loss and degradation of natural ecosystems. By highlighting areas of prime botanical importance, it is hoped that their conservation will be ensured by an adequate commitment of resources. Selection of the sites is based both on floristic statistics and on detailed first-hand knowledge of numerous botanists.

Cycads were a dominant part of the earths flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and sub-species dealt with in this Action Plan are threatened by habitat destruction and plant collecting, and more than half the known species are now classified as threatened.
