Biotope importance

Fish and crustaceans migrating into the intertidal zone to feed as the tide rises, are important predators of rocky shore species. Corkwing wrasse Crenilabrus melops rely heavily on the intertidal. Nucella lapillus is preyed on by numerous sea birds and wildfowl, however, the dog whelk is not considered to be an important food source, except where alternative food sources are absent (Crothers, 1985). However, there is not the diversity of species in ELR.BPat to provide the rich pickings for birds that are seen in some rocky shore biotopes.

Exploitation

There are no species present that are likely to be harvested from the ELR.BPat biotope. Fucoid plants are not present in high enough abundance for exploitation to be viable. However, rocky shores are widely exploited for a range of recreational uses including rock pooling, angling and as a resource for students and scientific researchers. Trampling has been shown to have a significant impact on community structure.
