The coastline of the province of A Coruña is home to many species of plants – many of them endangered – growing in the peculiar environments created by the interaction between the sea and the land, such as the Anllóns estuary.
The fact that this stretch of coast Ponteceso is included in an SPA (Special Protection Area for Birds) gives us an idea of the ornithological importance of Ponteceso coast.
