Site details
Site description: A IBA é consituída por duas zonas, ambas formadas por uma faixa desde a beira-mar até ao rebordo da falésia. A zona da Ponta da Ferraria - Mosteiros inicia-se na Ponta da Ferraria e termina na Ribeira do Mosteiro. A zona da Bretanha inicia-se no porto da Ponta da Ilha e estende-se até ao calhau norte dos Mosteiros. Os principais habitats são falésias com vegetação das costas macaronésicas, matos macaronésicos endémicos e vegetação vivaz das costas de calhaus rolados.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Additional biodiversity: Important for breeding seabirds, especially the Cory's Shearwater and the Little Shearwater.

Threats
Summary of threats to biodiversity at KBA: Feral terrestrial mammals (dogs, cats, rats and weasels) affect most of the seabirds, especially those who nest in holes and burrows. Invasive plant species like the cane reduces the available nesting habitat for seabirds. Garbage disposals affect landscape and the integrity of the habitats.
