Great East Heritage Species Sensitivity Maps

This data package includes layers of the Great East Heritage Species Sensitivity Maps produced in 2018-2019 by the ODONAT Grand Est network for DREAL Grand Est. Several layers are available: • Presence maps weighted by natural regions, giving an overall overview of the knowledge of the distribution of the species in the Greater East Region, • Simple presence cards (conventional Atlas cards) in meshes 10 x 10 km, • Mess weighted presence cards 10 x 10 km. The 10 x 10 km grid maps show more precisely the knowledge of the distribution of species and are used in addition to maps by natural regions. • Presence potential maps by hydrographic sections for two species of odonates. Maps were made for 91 wildlife species, selected according to criteria related to their conservation status or protection status (species for which regional action plans exist or have existed, included in red lists, annexes to European directives, national protection text, etc.) and for which data could be mobilised. These layers represent the state of knowledge at the time of their realisation, they should not be considered exhaustive. The presence of the species outside the identified areas is possible. Refer to the card reading instructions as well as PDF cards for more information.本数据集包包含2018-2019年由大东部蜻蛉研究网络（ODONAT Grand Est）为大东部大区环境与海洋事务局（DREAL Grand Est）制作的大东部遗产物种敏感性分布图（Great East Heritage Species Sensitivity Maps）图层。 本次提供的图层包括： • 按自然区域加权的物种出现分布图：整体呈现大东部大区物种分布的现有调研覆盖全貌； • 10×10km网格下的简易物种出现图（常规图集地图）； • 10×10km网格下的加权物种出现图。10×10km网格地图可更精准地体现物种分布的现有调研覆盖情况，可与自然区域分区地图搭配使用； • 针对两种蜻蛉目（Odonata）物种的水文分区潜在出现分布图。 本次制图共涵盖91种野生生物物种，筛选标准基于其保护现状或受保护地位（例如已制定/曾制定区域行动计划、列入红色名录、纳入欧盟指令附件、受国家保护法规保护等），且可获取相关调研数据。 上述图层仅反映制作完成时的调研现状，不应被视为穷尽式的完整数据集，物种可能出现在标注区域之外。 如需了解更多信息，请参阅地图阅读指南及配套PDF图集。
