Savage Islands, also referred to as the Selvagens Islands, (Portuguese: Ilhas Selvagens, pron. ; Islas Salvajes) consist of an uninhabitable and small archipelago in the North Atlantic Ocean roughly midway between Madeira and the Canary Islands at . The archipelago is comprised of two islands and several islets and is the southernmost region of Portugal.
The Savage Islands are administered by the Portuguese municipality of Funchal and are part of the freguesia of Sé of Funchal. They are set aside as a nature reserve. There are two reserve zones, one on Selvagem Grande Island and another one on Selvagem Pequena Island.
The archipelago consists of two islands and several islets, in two groups about apart:
As with all Macaronesian islands, the Savage Islands are of volcanic origin. On the larger islands, cones of extinct volcanoes are found, such as the Atalaia Summit on Selvagem Grande. Other summits include Tornozelos and Veado. Headlands include Atalaia and Leste on Selvagem Grande, and Norte, Oeste, Leste and Garajaus on Selvagem Pequena.
The Canary Islands were visited by European explorers, including natives of Minorca, since the 14th century. In 1402, Castile began the conquest of the Canary Islands to join them to the Castilian realm. During those years of fighting, Castilian ships did not visit the Savage Islands, thus they did not populate the islands, which were considered uninhabitable. Although the Canary Islands had been inhabited by a primitive population - the Guanches - human beings never set foot in the Madeira archipelago before the Portuguese discoveries and expansion. Thus, this island group presented itself to Portuguese navigators authentically uninhabited.
In 1438, the Portuguese mariner Diogo Gomes de Sintra declared that he had discovered the Savage Islands by chance, while returning to Portugal from the Guinea coast of Africa. He left the first written notice about the geography of Selvagem Grande, the group's main island, which constitutes the first official record of their discovery. However, the islands are not included in the list of possessions of Christ's Order. The Portuguese historian João de Barros includes them in the Canary Archipelago and Gaspar Frutuoso in the second edition of his work Saudades da Terra mentions "These islands, known as Selvagens, apparently were discovered by Castilians, have Castilian owner, as also Madeira and Azores archipelagos (...) which will belong to this glorious and powerful Catholic King, the greatest in the world". This was a convenient addition to the first edition, certainly not made by Frutuoso, with the purpose to flatter King Phillip II of Spain, during the period in which Portugal was united with the Spanish crown.
What is certain is that during the 16th century the Savage Islands belonged to a family from Madeira known as Teixeiras Caiados. How they found themselves under Caiados control is unknown. In 1560 they were given to João Cabral de Noronha. After 1717 they are recorded in wills, inheritances, inventories and other documents. Between 1774 and 1831 taxes were paid to the King. The islands were also recorded in the books of Conservatória do Registo Predial of Funchal.
In 1904 the islands were sold to Luís Rocha Machado.
The Permanent Commission of International Maritime Law gave sovereignty of the Savage Islands to Portugal on February 15, 1938. In 1959, the World Wildlife Fund (WWF) became interested in the islands and signed a contract-promise with the owner, Luis Rocha Machado. In 1971 the Portuguese government intervened and acquired the islands, converting them into a nature reserve. The Savage Islands Reserve was created as part of the Madeira Natural Park; it is one of the oldest nature reserves of Portugal and it also includes the surrounding shelf to a depth of 200 m. In 1976, permanent surveillance began, and in 1978 the reserve was elevated to the status of Nature Reserve.
In 2002, part of the nature reserve was nominated to UNESCO's World Heritage Sites. They are currently included in the tentative World Heritage Site list.
Today the Savage Islands have a permanent team of wardens from Madeira Natural Park (On Selvagem Grande there is a permanent research station with two wardens year around while Selvagem Pequena is manned usually by two wardens between May and October). These are the only human inhabitants on the islands.
The temperatures in the Savage Islands exceed those in Madeira and the sea temperature remains comfortable all year round. There is almost no rainfall (desertic climate i.e. below 200 mm). Jacques-Yves Cousteau once said he found the cleanest waters in the world there. Although there are commercial tours available, all visitors require special authorization from the Madeira Natural Park, the regional environmental authority. The scientific and natural interest of this tiny group of islands lies in its marine biodiversity and unique flora as well as the sea birds that breed there. The White-faced Storm-petrel, the Bulwer's Petrel, and the Roseate Tern breed and nest on the islands and are the subject of annual scientific expeditions.
The Savage Islands host 150 species of plants, most of them creepers. The richest islands in flora are the Selvagem Pequena and Fora Islet as they have never suffered the introduction of non-indigenous animals or plants. These islands also have many endemic species of plants, some endemic snails and also a unique gecko (Tarentola boettgeri bischoffi).
