The International Union for Conservation of Nature (IUCN) is a global leader in environmental conservation and sustainable development. Founded in 1948, IUCN brings together governments, civil society organizations and experts to develop and implement nature-based solutions to global challenges. The organization is widely recognized for its Red List of Threatened Species, which assesses the conservation status of biodiversity worldwide. Through science, policy, and fieldwork, IUCN plays a vital role in protecting ecosystems and promoting sustainable resource management.
