spawning grounds

Working layer carried out within the framework of the Environment Code; establishment of spawning inventories within the meaning of Article L.432-3 of the Environmental Code. The presence of spawning grounds symbolised by a point, is attached to homogeneous hydrogeomorphological sections (Syrah© Cemagref — 2009) or assimilated (BD Carthage®. For this inventory, two lists of ' species have been determined. The presence of spawning grounds of List 1 species are said to be probabilistic: a point on a section means that potential spawning grounds are found on the entire section. For species in List 2, l' approach is deterministic: a point on a section means that proven spawning grounds are found throughout the section. This layer is an export of the GeoIF tool. __Origin__ To say d'expert, with field visit __Partner organisations__ AFB [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/58dfa934063c5d3d96f03c4ae5205c09d58c4409)
