Marine natural heritage importance

Listed under EC Habitats Directive
National importance Rare
Habitat Directive feature (Annex 1) Reefs

Biotope importance

Shore birds feed on rocky shores on species such as limpets. Rich pickings are also available under macroalgae canopies. Fish and crustaceans, migrating into the intertidal zone to feed as the tide rises, are important predators of rocky shore species.

Exploitation

It is unlikely that species in this biotope will be exploited. The biotope occurs on remote and dangerously wave exposed shores.
