The compilation and production of The IUCN Red List of Threatened Species™ would not be possible without the financial support of many donors. IUCN would like to thank all the donors who have generously provided funds to support this work, and in particular would like to acknowledge the ongoing financial support from The Rufford Foundation and the MAVA Foundation for Nature Conservation (MAVA Stiftung für Naturschutz / Fondation pour la Protection de la Nature) that enable the production of the IUCN Red List.

In addition to considerable ongoing support provided by all the IUCN Red List Partners, other major donors to the Red List assessment process include the Moore Family Foundation; the Gordon and Betty Moore Foundation; the Critical Ecosystem Partnership Fund; the European Commission; the Esmée Fairburn Foundation; the French Ministry for Foreign Affairs (DgCiD – Direction générale de la Coopération internationale et du Développement); and the MacArthur Foundation. Further details about the specific contributions of these and other donors are included under the acknowledgement sections for the different assessment projects (see under Contributors).

To conduct Red List assessments and to make the information readily available requires the use of various tools including Geographic Information Systems (GIS) for mapping species ranges. IUCN gratefully acknowledges support from esri by providing GIS software and training under its Conservation Grant Program.
