Why Desertas Island is so well known?

The islands were the private property of two English families of Madeira, from 1894 to 1971, then were bought by the Portuguese State and converted into a Nature Reserve. While the protection of these islands was motivated by the urgency of taking measures for the conservation of the monk seal, its objective is the protection and preservation of all wildlife and unique flora and includes several species rare and endemic.

What does exist in Desertas Islands?

The Desert Islands are one of the last refuges of the monk seal (Monachus monachus), a colony estimated at 23 animals that are in the process of restocking. This space is also an important nesting site for seabirds. North of Deserta Grande Valley in Castanheira, the Tarantula is of desertion (Lycosa ingens), a species endemic to this island. These islands also feature a variety of plants.
