About the IUCN

The International Union for Conservation of Nature (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 has evolved into the world’s largest and most diverse environmental network. It harnesses the experience, resources and reach of its 1,300 Member organisations and the input of some 16,000 experts. IUCN is the global authority on the status of the natural world and the measures needed to safeguard it. Our experts are organised into six commissions dedicated to species survival, environmental law, protected areas, social and economic policy, ecosystem management, and education and communication.

IUCN Species Programme, in conjunction with the IUCN Species Survival Commission (SSC) and partners, are driving the fight to save species for people and nature through many initiatives, including the continuing development of The IUCN Red List of Threatened Species, and supporting on the ground conservation projects through Save Our Species (SOS) and the Integrated Tiger Habitat Conservation Programme (ITHCP).  Learn More

Species Survival Commission

The IUCN Species Survival Commission (SSC) is a science-based network of more than 10,000 volunteer experts from almost every country of the world, all working together towards achieving the vision of, “A just world that values and conserves nature through positive action to reduce the loss of diversity of life on earth”.

Most members are deployed in more than 140 Specialist Groups, Red List Authorities, Task Forces and Sub-Committees. Some groups address conservation issues related to particular groups of plants, fungi or animals while others focus on topical issues, such as reintroduction of species into former habitats or wildlife health. Learn More
