TermDefinition
Management SchemeA plan, prepared by the relevant authorities, that sets the framework within which activities will be managed to achieve the conservation objectives of a European marine site (Defra, 2007).
Marine Conservation Zones (MCZs)Marine Conservation Zones (MCZs) are a new type of Marine Protected Area (MPA) brought in under the UK Marine Act. Marine Conservation Zones will form a key part of the UK MPA network.
Marine Conservation Zones afforded a high level of protectionWelsh inshore marine sites in which all damaging and disturbing activities will be excluded. They will be recommended to the Welsh Assembly Government by the Countryside Council for Wales in 2012.
Marine Consultation Area (MCA)A non-statutory nature conservation designation for Scotland. It identifies areas of nature conservation interest for which widespread consultation is desirable before any development takes place (Anon, 2001).
Marine inletAs defined for the Habitats Directive, 'large shallow inlets and bays' are: "Large indentations of the coast where, in contrast to estuaries, the influence of freshwater is generally limited. These shallow indentations are generally sheltered from wave action and contain a great diversity of sediments and substrates with a well developed zonation of benthic communities" (European Commission 1995). 'Shallow' may be defined by the depth limit of the photic zone in open coastal waters adjoining the inlet or bay. In the UK this is interpreted for the Habitats Directive as a depth of 30 m below chart datum or shallower across at least 75% of the site."
Marine Nature Reserve (MNR)an area of sea and seabed (which can include intertidal areas) designated under the Wildlife and Countryside Act (1981) for the purpose of conserving marine flora and fauna or geological or physiographic features of special interest and/or providing opportunities for study and research. The designation can be applied throughout UK territorial waters; sites designated already are Lundy MNR (England), Skomer MNR (Wales), Strangford Lough MNR (Northen Ireland) (Anon, 2001).
Marine Protected Area (MPA)Any area of intertidal or subtidal terrain, together with its overlaying water and associated fauna, flora, historical and cultural features, which has been reserved by law or other effective means to protect part or all of the enclosed environment (Kelleher 1999) (from Anon, 2001).
MudflatAn expanse of mud or muddy sediment in the intertidal zone. The 1991 CORINE biotopes manual (Commission of the European Communities, 1991) defines 'Mud flats and sand flats' as "Sands and muds, submerged for part of the tide, devoid of vascular plants, but usually coated by blue algae and diatoms." The EC Habitats Directive 'mudflats and sandflats not covered by seawater at low tide' uses the same definition (European Commission, 1995).
