Estuaries provide doorways for many creatures, creating corridors that link rivers to the sea.

Providing important feeding grounds for migratory birds and nursery grounds for many marine fish, like plaice.

This site has been designated to protect the estuarine habitats found here including coastal sealtmarshs, saline reedbeds and restuarine rocky habitats.

Located on the Northumberland coast this is one of only two estuaries recommended within the North Sea. Estuaries provide a link between the land and sea and are home to unique communities of life making them of particular importance within the MCZ network.

The Aln has been recommended for a range of habitats including mud, sand, gravel, sheltered muddy gravel, estuarine rocky habitats, saltmarsh and saline reedbed. It is one of the few places within the North Sea supporting seagrass and has significant importance for feeding and roosting birds, including gulls, dunlins and other waders such as redshanks, curlews, snipe and wigeons. Estuaries are also important for juvenile fish. The Aln supports sprat, flounder, sandeel, plaice and European eel.
