PROJECT 99-1483 

Correlates of Extinction Risk for Central Asian Biodiversity

Project participants:

Imperial College London, UKInstitute of Zoology, UZIUCN - World Conservation Union, CHInstitute of Zoology, KZSwedish Threatened Species Unit, SEInstitute of Deserts, TMInstitute of Zoology and Parasitology, TJInstitute of Botany, KZ

Objectives• To integrate the Red

Listing system used by the Central Asian countries into the global framework IUCN-SSC.

• To develop a system for assessing the threat of extinction of Central Asian species at 3 levels: national, regional and global.

Objectives• To use archive data to

correlates extinctions of the listed species at the national, regional and global scales.

• To product of GIS for extinction risk.

• To initiate and support a collaborative network of CA scientists.
