Frayères

Work layer carried out as part of the establishment of spawning grounds inventories within the meaning of Article L.432-3 of the Environment Code.
The presence of spawning grounds symbolized by a dot is related to homogeneous (Syrah© Cemagref - 2009) or similar (BD Carthage®) hydrogeomorphological sections.
For this inventory, two species lists were determined. The presence of spawning grounds of the species in List 1 is said to be probabilistic: a point on a section means that potential spawning grounds are found throughout the section. For the species in List 2, the 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.
