  • EC_Habitats

Marine natural heritage importance

Listed under EC Habitats Directive
National importance Uncommon
Habitat Directive feature (Annex 1) Mudflats and sandflats not covered by seawater at low tide
Large shallow inlets and bays

Biotope importance

Biotopes such as LGS.Lan support large nursery populations of flatfishes and round fishes prior to their movement offshore and eventual commercial exploitation, e.g. Elliott et al., 1990 (Elliott et al., 1998).


Commercial shell fisheries potentially can have a large effect on the integrity of intertidal sandflats, their physical structure and biological components (Jennings & Kaiser, 1998, Elliott, 1998). For instance, mechanical cockle harvesting or bait-digging may potentially cause reduced community diversity and species richness through removal, scattering or damage to individuals (Elliott et al., 1998).
