IUCN SSC Mid-Atlantic Island Invertebrates Specialist Group


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

Only 42 species of arthropods and molluscs were assessed from Azores until recently.  In this last year we assessed about 130 species of arthropods from Azores. Our aim is to assess all endemic species of Macaronesia and Southern Atlanti 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.
