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. Capture of Cory's Shearwaters exist in small scale. Invasive plant species like the cane reduces the available nesting habitat for seabirds. Natural land slides occur often. The absence of the establishment of the SPA by the regional law constitutes a weakness in its surveillance and legal protection. There is a management plan for the SPA Costa do Corvo.
