Status Survey and Conservation Action Plan West African Chimpanzees Compiled and edited by Rebecca Kormos, Christophe Boesch, Mohamed I. Bakarr and Thomas M. Butynski IUCN/SSC Primate Specialist Group IUCN The World Conservation Union Donors to the SSC Conservation Communications Programme and West African Chimpanzees Action Plan The IUCN Species Survival Commission is committed to communicating important species conservation information to natural resource managers, decision makers and others whose actions affect the conservation of biodiversity. The SSC’s Action Plans, Occasional Papers, newsletter Species and other publications are supported by a wide variety of generous donors including: The Sultanate of Oman established the Peter Scott IUCN/SSC Action Plan Fund in 1990. The Fund supports Action Plan development and implementation. To date, more than 80 grants have been made from the Fund to SSC Specialist Groups. The SSC is grateful to the Sultanate of Oman for its confidence in and support for species conservation worldwide. The Council of Agriculture (COA), Taiwan has awarded major grants to the SSC’s Wildlife Trade Programme and Conser- vation Communications Programme. This support has enabled SSC to continue its valuable technical advisory service to the Parties to CITES as well as to the larger global conservation community. Among other responsibilities, the COA is in charge of matters concerning the designation and management of nature reserves, conservation of wildlife and their habitats, conser- vation of natural landscapes, coordination of law enforcement efforts, as well as promotion of conservation education, research, and international cooperation. The World Wide Fund for Nature (WWF) provides significant annual operating support to the SSC. WWF’s contribution supports the SSC’s minimal infrastructure and helps ensure that the voluntary network and publications programme are adequately supported. WWF aims to conserve nature and ecological processes by: (1) preserving genetic, species, and ecosystem diversity; (2) ensuring that the use of renewable natural resources is sustainable both now and in the longer term; and (3) promoting actions to reduce pollution and the wasteful exploitation and consumption of resources and energy. WWF is one of the world’s largest independent conservation organizations with a network of National Organizations and Associates around the world and over 5.2 million regular supporters. WWF continues to be known as World Wildlife Fund in Canada and in the United States of America. The Great Ape Conservation Fund was established by the Great Ape Conservation Act of 2000 to assist in the conservation and protection of five primate groups – chimpanzees, gorillas, bonobos, orangutans and gibbons. The United States Fish and Wildlife Service (USFWS) works to achieve the objectives of the Fund by developing partnerships with natural resource management agencies, academic institutions, local community groups, government and non-government entities, and any other experienced organization or individual committed to partnering for the benefit of ape conservation. The Great Ape Conservation Fund provided the main funding for the development of an action plan for chimpanzees in West Africa. The Critical Ecosystem Partnership Fund (CEPF) is a joint initiative of Conservation International, the Global Environment Facility, the Government of Japan, the John D. and Catherine T. MacArthur Foundation and the World Bank. CEPF aims to dramatically advance conservation of Earth’s biodiversity hotspots by providing support to non-governmental, community and grassroots organizations. A fundamental goal is to ensure civil society is engaged in biodiversity conservation. CEPF provided funding for the publication, translation and dissemination of this document. The Primate Action Fund’s principle objective is to contribute to global biodiversity conservation by providing strategically targeted, catalytic support for the conservation of endangered nonhuman primates and their natural habitats. The Primate Action Fund also provided funding for the publication, translation and dissemination of this document. Conservation International’s (CI) mission statement is to conserve the Earth’s natural living heritage, our global biodiversity, and to demonstrate that human societies are able to live harmoniously with nature. CI applies innovations in science, economics, policy and community participation to protect the Earth’s richest regions of plant and animal diversity in the hotspots, major tropical wilderness areas and key marine ecosystems. CI provided support for the development, compi- lation and editing of this document. The Center for Applied Biodiversity Science (CABS) was launched at CI in 1998 to strengthen it’s research capabilities in order to accurately identify and quickly respond to emerging biological diversity threats. The key role of the Center for Applied Biodiversity Science is the acquisition and analysis of biological data to support priority-setting and analysis in the key regions targeted by CI – the Hotspots and the Tropical Wilderness Areas – as well as on continental and global scales appropriate for conservation planning. CABS provided support and expertise for the editing, layout and design, maps, printing and dissemination of this document.
