(SRCE) Corridors Watercourses providing connections between biodiversity reservoirs

This table lists the different ecological corridors that provide connections between biodiversity reservoirs, providing favourable conditions for species to move and complete their life cycle. (Article R. 317-19 III of the Environmental Code). These corridors represent principles for connecting biodiversity reservoirs. Their location must be specified at the local level. Origin Ecological corridors resulting from the consultation in the second wave workshop of stakeholders in the region. It was agreed that “message envelopes” will be used as a medium for the identification of ecological corridors. However, Level 4 forest envelopes are not retained by the Expert Committee. In addition, Level 3 envelopes are displayed in hatches to retranscribe the broadcast character of the subtrame. The reservoirs of biodiversity are represented in the same colour, whether they belong to the Green Trame or the Blue Trame. For Blue Trame, BD CARTHAGE© streams and wetlands of national significance are proposed as ecological corridors. Fragmentation is represented in two ways: linear fragmentation (levels 1 to 3) and surface (urban task) for the Green Trame. For the Blue Trame, the Referential of Obstacles to Flow is used.
