The Azores is a remote oceanic archipelago of nine islands which belongs to the Macaronesia biogeographical region and is among the richest regions concerning fungi, plant and animal diversity in Europe. This checklist lists all the species of the most important terrestrial and marine taxonomic groups. The total number of terrestrial and marine taxa (species and subspecies) in the Azores is estimated in about 8047. The marine organisms currently listed make up about 23% of the Azorean biodiversity. The total number of terrestrial and marine endemic taxa (species and subspecies) in the Azores is estimated of about 491.

This dataset is based on a National Report on the progress and implementation of the Habitats Directive in Portugal, concerning the 2007-2012 period. It originates from a project performed periodically (every 6 years) that aims to permit an adequate assessment of the progress, via the Natura 2000 Network, towards the goals of the Habitats Directive. This national reports describes conservation status for flora and fauna species in three biogeographic regions (Atlantic, Macaronesian and Mediterranean) and two marine regions (Atlantic and Macaronesian). It contains occurrence data for fauna and flora belonging to 3 kingdoms, 7 phyla, 16 classes, 52 orders, 104 families, 188 genera and 271 species.

This checklist includes, as rigorously as possible, all the known terrestrial and freshwater, i.e. insular, fungi, plants and animals of the Madeira and Selvagens archipelagos with the indication of their known presence on the islands of Madeira, Porto Santo, Desertas and Selvagens. It results from the collaborative work of many taxonomists from different Portuguese and foreign institutions (about 90 taxonomists), under the editorial coordination of the Azorean Biodiversity Group (http://www.gba.uac.pt). The total estimated number of terrestrial species and subspecies in the Madeira and Selvagens archipelagos was about 7,571 (7,452 species and 421 subspecies). Fungi and plants represent about 42% of the terrestrial diversity. However, animals dominate, arthropods being the majority (51%) of all recorded taxa. The total number of endemic species and subspecies from the Madeira and Selvagens archipelagos is about 1,419 (1,286 species and 182 subspecies), which represents 19% of the overall species diversity. The animal Phyla are the most diverse in endemic taxa, namely Mollusca (210) and Arthropoda (979), comprising about 84% of the Madeiran endemics. The percentage of endemism within Mollusca is particularly remarkable, reaching 71%. Within vascular plants there are 154 endemic species and subspecies (13% of the overall plant species diversity) while the remaining higher taxonomic groups are less diverse in terms of endemic forms: Fungi – 36 (5%); Lichens – 12 (2%); Bryophytes – 11 (2%); vertebrates 15 (24%).
