Regional action plan for the conservation of western chimpanzees (Pan troglodytes verus) 2020–2030 IUCN SSC Primate Specialist Group INTERNATIONAL UNION FOR CONSERVATION OF NATURE IUCN SSC SpecialistPRIMATE Group About IUCN IUCN is a membership Union uniquely composed of both government and civil society organisations. It provides public, private and non- governmental organisations with the knowledge and tools that enable human progress, economic development and nature conservation to take place together. Created in 1948, IUCN is now the world’s largest and most diverse environmental network, harnessing the knowledge, resources and reach of more than 1,400 Member organisations and some 15,000 experts. It is a leading provider of conservation data, assessments and analysis. Its broad membership enables IUCN to fill the role of incubator and trusted repository of best practices, tools and international standards. IUCN provides a neutral space in which diverse stakeholders including governments, NGOs, scientists, businesses, local communities, indigenous peoples organisations and others can work together to forge and implement solutions to environmental challenges and achieve sustainable development. Working with many partners and supporters, IUCN implements a large and diverse portfolio of conservation projects worldwide. Combining the latest science with the traditional knowledge of local communities, these projects work to reverse habitat loss, restore ecosystems and improve people’s well-being. www.iucn.org https://twitter.com/IUCN/ IUCN Species Survival Commission With over 8,000 members, the Species Survival Commission (SSC) is the largest of the six expert commissions of IUCN and enables IUCN to influence, encourage and assist societies to conserve biodiversity by building knowledge on the status and threats to species, providing advice, developing policies and guidelines, facilitating conservation planning, and catalysing conservation action. Members of SSC belong to one or more of the 140 Specialist Groups, Red List Authorities, Task Forces and Conservation Committees, each focusing on a taxonomic group (plants, fungi, mammals, birds, reptiles, amphibians, fishes and invertebrates), or a disciplinary issue, such as sustainable use and livelihoods, reintroduction of species, wildlife health, climate change and conservation planning. www.iucn.org/theme/species/about/species-survival-commission twitter.com/iucnssc IUCN Global Species Programme The IUCN Global Species Programme supports the activities of the IUCN Species Survival Commission and individual Specialist Groups, as well as implementing global species conservation initiatives. It is an integral part of the IUCN Secretariat and is managed from IUCN’s international headquarters in Gland, Switzerland. The Species Programme includes a number of technical units covering Wildlife Trade, the Red List, Freshwater Biodiversity Assessments (all located in Cambridge, UK), and the Global Biodiversity Assessment Initiative (located in Washington DC, USA). www.iucn.org/species IUCN SSC Primate Specialist Group The Primate Specialist Group (PSG) is concerned with the conservation of more than 700 species and subspecies of prosimians, monkeys, and apes. Its particular tasks include carrying out conservation status assessments, the compilation of action plans, making recommendations on taxonomic issues, and publishing information on primates to inform IUCN policy as a whole. The PSG facilitates the exchange of critical information among primatologists and the professional conservation community. The PSG Chair is Dr. Russell A. Mittermeier and the Deputy Chairs are Drs. Anthony B. Rylands and Christoph Schwitzer. The Vice Chairs of the Section on Great Apes are Dirck Byler and Prof. Serge Wich. www.primate-sg.org Regional action plan for the conservation of western chimpanzees (Pan troglodytes verus) 2020–2030 Regional action plan for the conservation of western chimpanzees (Pan troglodytes verus) 2020–2030 IUCN SSC Primate Specialist Group The designation of geographical entities in this book, and the presentation of the material, do not imply the expression of any opinion whatsoever on the part of IUCN or other participating organisations concerning the legal status of any country, territory, or area, or of its authorities, or concerning the delimitation of its frontiers or boundaries.
