2009 Defra MB0102 2B Distribution of Heleobia stagnorum in the United Kingdom and Isle of Man

This layer shows the distribution of the mollusc, Heleobia stagnorum, a Wildlife and Countryside Act Species. A number of commercially collected records have been unavailable for use in the collation of this dataset and it may be present in some areas not shown in this map. 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.本图层展示了软体动物Heleobia stagnorum的分布范围，该物种为《野生动物与乡村法》保护物种。部分商业采集的记录无法用于本数据集的整理工作，因此该物种可能存在于本地图未标注的部分区域。 本图层为英国环境、食品与农村事务部（Defra）MB0102号合同项下开发的一系列数据图层之一。本项目将助力建设符合现有国际与国内义务及承诺要求的海洋保护区网络，其中包括作为《海洋与沿海通道法案》新增举措的海洋保护区域（Marine Conservation Zones，MCZs），以及苏格兰立法框架下的同类保护措施。此类数据图层的可用性，同样可为英国海域的海洋规划（如许可审批）提供重要支撑。
