2009 Defra MB0102 2C Distribution of intertidal Mytilus edulis beds on mixed and sandy sediments (from polygon data) in the United Kingdom and Isle of Man

This layer shows the distribution of polygon records of intertidal Mytilus edulis beds on mixed and sandy sediments , an OSPAR Habitat. This layer forms one of a set of data layers created for the Defra MB0102 contract. This work will support the delivery of a network of Marine Protected Areas as required to meet existing international and national obligations and commitments, including Marine Conservation Zones (MCZs), a new measure to be delivered as part of the Marine and Coastal Access Bill, and equivalent measures under Scottish legislation. The availability of these data layers will also be of importance in underpinning Marine Planning (e.g. licensing) in our marine area.本图层展示了分布于混合沉积物与砂质沉积物上的潮间带紫贻贝（Mytilus edulis）床多边形要素记录，该生境属于东北大西洋海洋环境保护委员会（OSPAR）划定的生境类型。 本图层为英国环境、食品与农村事务部（Defra）MB0102号合同所开发的系列数据图层之一。此项工作将支撑海洋保护区网络的建设，以履行现有国际与国内相关义务及承诺，其中包括作为《海洋与海岸出入法案》（Marine and Coastal Access Bill）配套举措的海洋保护区域（Marine Conservation Zones, MCZs），以及苏格兰立法框架下的等效措施。上述数据图层的可用性，也将为本国海域内的海洋规划（如许可审批）工作提供重要支撑。
