Species

Over 150 Atlantic islands species are threatened with extinction. Help us secure their future.

Our aim is to assess all endemic species of Atlantic islands, which will be a daunting task.

What are Red Lists?

The IUCN Red List assesses the extinction risk of the world’s plant, animal and fungi species.
