Reliable and timely information on the status of biodiversity and the health of our environment is fundamental when taking environment-related decisions. IUCN provides governments, the private sector, multilateral agencies responsible for natural resource use, and environmental treaties with access to state-of the-art information and trends on biodiversity.
IUCN derives its value as a trusted source of knowledge from its expert groups, its Members, and its Secretariat. An example of this work in Europe is the European Red List. It is a review of the conservation status of European species according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the pan-European and EU levels so that appropriate conservation action can be taken to improve their status. Red List training is also provided to help governments with their national assessments.
