Through its six Commissions, lUCN draws together over 5000 expert volunteers in project teams and action groups. A central secretariat coordinates the lUCN Programme and leads initiatives on the conservation and sustainable use of the world's biological diversity and the management of habitats and natural resources, as well as providing a range of services. The Union has helped many countries to prepare National Conservation Strategies, and demonstrates the application of its knowledge through the field projects it supervises. Operations are increasingly decentralised and are carried forward by an expanding network of regional and country offices, located principally in developing countries. I UCN - The World Conservation Union seeks above all to work with its members to achieve development that is sustainable and that provides a lasting Improvement in the quality of life for people all over the world. World Conservation Monitoring Centre The World Conservation Monitoring Centre (WCI^C) is a joint venture between the three partners who developed the World Conservation Strategy and its successor, Caring for the Earth: lUCN - The World Conservation Union, UNEP - United Nations Environment Programme., and WWF - World Wide Fund For Nature (formerly World Wildlife Fund). Its mission is to support conservation and sustainable development through the provision of information on the world's biological diversity. WCMC has developed a global overview database that includes threatened plant and animal species, habitats of conservation concern, critical sites, protected areas of the world, and the utilisation and trade in wildlife species and products. Drawing on this database, WCMC provides an information service to the conservation and development communities, governments and the United Nations agencies, scientific institutions, the business and commercial sector, and the media. WCMC produces a wide variety of specialist outputs and reports based on analyses of its data. It Is also actively involved in building the capabilities of other institutions, particularly In developing countries, for promoting and planning their own biological resources. 1994 lUCN Red List of Threatened Animals Compiled by the World Conservation l\/lonitoring Centre Cambridge, UK in association with the lUCN Species Survival Commission and BirdLife International Edited by Brian Groombridge Guest Essay by Georgina Mace and Foreword by George Rabb lUCN - The World Conservation Union 1993 presentation of the The designations of geographical entities in this boolc, and the on the part of lUCN or material, do not imply the expression of any opinion whatsoever of its authorities, WCMc'conceming the legal status of any country, territory, or area or or concerning the delimitation of its frontiers or boundaries. 1994 lUCN Red Use of Threatened Animals was made possible by the generous support of: BirdLife International Chicago Zoological Society DEJA, Inc.

Our knowledge has changed in expression through the years, as lUCN's small book The Road to Extinction'. pubUshed in 1987 testifies. For some while, members of lUCN's Species Survival Commission have been considering the redefinition of the categories of threatened status of species in order to make them more reaUstic measures. The essay by Georgina Mace that follows is an up-to-date report on this process. We anticipate that the next Red List will reflect the adoption of new and redefined categories by lUCN. In the meantime we look to cooperation from all parties as systematic re-examination of the status of taxonomic groups and surveys of regional and national biotas proceed. To inform conservation actions we will need ever better specification of the population and distributional status of species the world over from people in touch with the real situations of these species. In closing her essay, Dr Mace calls attention to other dimensions, both biological and human, that should be taken into account as we determine the best responses to the threats of extinction. One need is to link a quantitative grid of population and distribution criteria such as outlined in her essay to an assessment of the relative importance of a species. The evolutionary and ecological values of a species should be factored into our prioritization of conservation action. Weighting and decision making systems such as that developed by Williams, Vane-Wright, and Humphries, lend themselves to this purpose." The integration of such systems will, however, require cooperation by systematists and ecologists with conservation biologists to a degree not previously envisaged. Given that we can foresee a three-dimensional assessment of conservation status from a biological standpoint, it remains to factor in the human dimensions. From simple human population impact relationships on a species or its ecosystem to complexities of constunptive and non-consumptive uses of species, we need conservationists to foster collaboration by demographers, economists, and sociologists. The human domain in which issues of extinction generally will be settled is political, at local, national, and international levels. There a balance has to be struck among ethical, financial, socioeconomic, and biological considerations. We need the most cogent information to bring to the decisions in this realm, and we need it organized to best effect. To these ends, the conservation community must encourage the rapid development of systems for not only better categorizing the conservation status of species, but also for deteimining logical priorities for conservation action more comprehensively than we have in the past. In signing off this foreword, it is a pleasure to acknowledge and commend the diUgence of WCMC staff, in particular Dr Brian Groombridge, in compiling this new Red List. They have made i'
