Indonesia is one of the world’s largest biodiversity hotspots, outstanding not only in terms of biological richness and endemicity, but also reflecting the urgency to prioritize its conservation. The objectives of this SSC Group are: To engage experts on the country`s biodiversity to establish close coordination with representatives from key partners and government agencies, especially focusing on overlooked taxonomic groups (e.g., freshwater fishes, invertebrates, marine plants, marine mammals/marine megafauna, and fungi) and unrepresented geographical areas, especially from the eastern parts of Indonesia; To develop and regularly update Indonesia's National IUCN Red List of Threatened Species based on the global IUCN Red List of Threatened Species, as well as conducting regional Biodiversity/Species Conservation Planning, strengthening the network and capacity building for local scientists and conservation practitioners; To conduct regular meetings to strengthen the network, identify research and intervention priorities, and support the development of smaller working groups in response to certain biodiversity issues or initiatives; To build public constituents to support pro-biodiversity policies and mainstream biodiversity issues across sectors and ministries through diverse communication channels; To facilitate international collaboration where Indonesian scientists can contribute meaningfully to the international agenda to reverse biodiversity loss and growing scientific evidence of global biodiversity status.
