Corvo Biosphere Reserve

The Corvo Island Biosphere Reserve, classified in September 2007, covers an area of 25,852.88 hectares that includes all the island's land area and a surrounding marine zone.

This Reserve stands out with its unique landscapes and exceptional ecological, geological, environmental and cultural values, which transcend the regional level to a national and international level, in particular, by serving as a nesting site for seabird species, many of them listed in Annex I of the Birds Directive of the European Union.
Within the Biosphere Reserve boundaries are also various marine and coastal habitats, evergreen forests and altitude vegetation.

The marine habitats are of immense natural and ecological importance and are among the best-preserved of the Azores archipelago.
Notably, the south of the island is a treasure of unique geomorphological features, including reefs that create a myriad of microhabitats, fostering a high level of marine diversity. Arches and semi-submerged caves along the coast further enhance the area's ecological richness.
Of the biological diversity, many endemic and rare species are also present, such as the Azores Grayling (Hipparchia azorina occidentalis) and the Azorean Forget-me-not plant (Myosotis azorica), both endemic to the Archipelago and whose distribution is restricted to the islands of Corvo and Flores.
