Protected Area for the Management of Habitats or Species
With 112 hectares, this protected area constitutes a coastline that lies between the seashore and the edge of the sea-cliff, from the Porto da Baixa, in Ribeirinha, to the Ribeira das Gramelas (stream) in Santo Amaro.
It is characterized by a continuous sea-cliff of high altitude, finding its highest point at about 400 metres of altitude, where there is the Terra Alta Viewpoint.
Despite the fairly rugged morphology, this sea-cliff that was once cultivated (vines, fruit trees, taros) by the local people, is now a densely forested scarp with Macaronesian woodland from the coastline to the top of the sea-cliff.
This area is particularly important for the birds Sterna dougallii, Calonectris borealis and Puffinus lherminieri baroli.
This protected area is also an Important Bird and Biodiversity Area (IBA) of the BirdLife International organization.
