Nature goals Sigmaplan

This map layer gives the nature goals for the nature development areas of the Sigma Plan. The layer is a spatial translation of the nature objectives formulated in 2005 for the Scheldt estuary, its valley and tributaries (Adriaensen et al. 2005, Conservation objectives Scheldt estuary - ECOBE 05-R82, UA - IN - KULeuven) and in 2014 in the S-IHD 36 Zeeschelde (SIGMA). The implementation of the Sigma Plan focuses on these goals and thus contributes to the realization of the mission statement from the Management Plan 36 Zeeschelde (SIGMA) for the SPA-H BE2300006 and SPA-V BE2300222, BE2301235 and BE2301336. The nature goals are partly located outside SPAs. The map layer guides the design and management of the nature development areas of the Sigma Plan. It is a work map that is frequently updated on the basis of new insights and the concrete implementation of the layout plans. The limitation of the targets is based on ecological potentials as calculated in preliminary design studies and visions. For those areas where such data is not yet available, the target is derived from the Most Desirable Alternative of the updated Sigma Plan.本地图图层明确了西格玛计划（Sigma Plan）自然开发片区的自然保护目标。该图层是2005年为斯海尔德河河口（Scheldt estuary）、其流域及支流制定的自然保护目标（Adriaensen等，2005年：《斯海尔德河河口保护目标 - ECOBE 05-R82，UA - IN - KULeuven》），以及2014年在S-IHD 36泽谢尔讷海槽（SIGMA）中确立的自然保护目标的空间化表达。西格玛计划的实施以这些目标为核心，助力达成《泽谢尔讷海槽管理计划36》（SIGMA）中针对特别保护区域（Special Protection Area, SPA）的H类站点BE2300006与V类站点BE2300222、BE2301235及BE2301336的使命宣言。部分自然保护目标位于特别保护区域之外。本图层为西格玛计划自然开发片区的设计与管理提供指引，属于可根据最新研究认知与布局方案的具体实施情况定期更新的工作地图。本图层所设定的自然保护目标，其范围划定依据初步设计研究与生态愿景中测算得到的生态潜力确定；对于暂未获取此类数据的区域，其保护目标则取自更新版西格玛计划的最优备选方案。
