This publication represents the first time that the work of the various Specialist Groups in the IUCN Species Survival Commission (SSC) has been drawn together for the African continent The result is that we now have a much clearer basis on which to make decisions about allocating resources to biological diversity conservation on the continent. As a member of the SSC for 20 years and as Director of an IUCN member organisation, I warmly applaud this initiative and hope that the SSC will see fit to apply this model in other regions of the world. This publication will only have a major impact if people take it seriously. I recommend that it be priority reading for govern- ment officials in natural resource management agencies, as well as for those working for development assistance agencies and non-governmental organisations in the African continent I would encourage readers to study the first four general chapters, and then the country chapters of their choice. I would also like to take this opportunity to thank those who compiled this volume, and those who took the time to provide extensive comments on earlier drafts. I am sure that all will be happy with the final product Eric L.
