Spawning sites of species in the spawning inventory in Poitou-Charentes

This layer is an export of the GeoIF tool. It is a layer of work carried out within the framework of the establishment of spawning inventories within the meaning of Article L.432-3 of the Environmental Code. The tool GeoIF can be attributed to homogeneous hydrogeomorphological sections (Syrah© Cemagref — 2009) or assimilated (BD Carthage®) the presence of spawning grounds symbolised by a point. For this inventory, two lists species have been determined. The presence of spawning sites of the species in List 1 are said to be probabilistic: a point on a section means that potential spawning sites are found throughout the section. For species in List 2, the approach is deterministic: a point on a section means that spawning areas proven are found on the entire section.本图层为GeoIF工具（GeoIF）的导出产物，对应《环境法典》第L.432-3条定义范围内的产卵场清单编制工作所产出的专题图层。 GeoIF工具可将以点位标记的产卵场分布信息，关联至均质水文地貌区段（Syrah© 法国农业环境工程研究中心Cemagref，2009年）或等效数据集（BD Carthage®）。 本次清单编制确定了两类物种名录。对于名录1中的物种，其产卵场存在判定为概率性：若某区段上存在一个点位，则代表该整片区段内均存在潜在产卵场；对于名录2中的物种，其产卵场存在判定为确定性：若某区段上存在一个点位，则代表该整片区段内均已证实存在产卵区域。
