Baía de São Lourenço

Covering 178 hectares, the Baía de São Lourenço stretches between Ponta dos Matos and Ponta das Salinas, and is characterised by sandy seabeds and lava flows, which support marine habitats and ecosystems of great ecological value. The diversity of seabed features and the quality of its waters make this area an important natural nursery, and its protection is essential to ensure the sustainable use of its resources.

The bay is home to several biodiversity niches, hosting coastal and juvenile species of great ecological importance, such as the White Seabream (Diplodus sargus), Thicklip Grey Mullet (Chelon labrosus), the Parrotfish (Sparisoma cretense) and the Island Grouper (Mycteroperca fusca). Larger species or those with migratory behaviour are also frequently found, such as the Loggerhead Turtle (Caretta caretta), the Thornback Ray (Raja clavata) and the Common Stingray (Dasyatis pastinaca). The ecological importance of this area is further reflected in its designation as an Integral Reserve Zone for Limpet Capture, which contributes to the protection of intertidal ecosystems.

Opposite Ponta Negra lies Ilhéu do Romeiro, also known as Ilhéu de São Lourenço, which is home to Furna do Ilhéu do Romeiro, a cave formed by volcanic erosion, featuring stalactites created by the prolonged action of water and minerals. This islet is one of the most important nesting sites for seabirds in the bay, and it is common to spot the Cory’s Shearwater (Calonectris borealis) and the Common Tern (Sterna hirundo), amongst other species that use the islet to breed or rest.
