The Science and Knowledge team facilitates and catalyses integration of science into IUCN’s programme and promotes enhanced knowledge management to support better conservation practice.
Working with IUCN’s Members, Commissions, Secretariat and partners around the world, we strive to ensure the best possible scientific basis for IUCN policy and action.
