Santa Maria Island Red Desert
Região Autónoma dos Açores
The Santa Maria Island Red Desert, locally known as Barreiro da Faneca, is a distinctive semi-arid landscape located in the São Pedro parish on Santa Maria Island in the Azores. Spanning approximately 1542 hectares, this protected area extends from Ponta dos Frades to the island's northern tip, encompassing the Barreiro da Faneca and the bays of Raposo, Cré, and Tagarete. The terrain is characterized by its yellow-reddish clay soil, part of the Feteiras Formation, creating a rare semi-desert environment unique in the Azores. The landscape features gently undulating relief with altitudes around 200 meters and low slopes under 5%, where wind and water erosion have sculpted dune-like formations. While historically sparsely vegetated, recent decades have seen a natural increase in plant coverage, now covering about 70% of the area with endemic species such as Erica azorica (heather), Picconia azorica (pau-branco), Scabiosa nitens, and others. The adjacent bays offer significant geological and ecological value, with sedimentary formations containing well-preserved fossils and steep cliffs serving as vital nesting habitats for protected seabirds including Calonectris diomedea borealis (Cagarro) and Sterna species. This blend of geological uniqueness, endemic flora, and important avian habitats makes the Barreiro da Faneca a remarkable natural feature in the Azores.
