Southeast Asia is one of the most important places on earth for nature conservation. The region supports one sixth of the world’s species of mammals and amphibians, a fifth of the world’s species of butterflies, and almost a quarter of the world’s species of birds. This is also home to around half a billion people. The IUCN Southeast Asia Group was established in 2011, to support the growth of IUCN’s work in Southeast Asian countries, particularly through multi-country/trans-boundary interventions, and to provide a platform for IUCN interaction with Regional bodies such as ASEAN.
