(SRCE) Corridors Watercourses ensuring connections between biodiversity reservoirs
Description
This table lists the different ecological corridors that ensure connections between reservoirs of biodiversity, offering species favourable conditions for their movement and the completion of their life cycle. (Article R. 317-19 III of the Environmental Code). These corridors represent principles of connection between biodiversity reservoirs. Their location must be specified at the local level.
Origin
Ecological corridors resulting from the second wave workshop consultation of stakeholders in the region.
It was agreed that the “mesh 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 transcribe the diffuse character of the subtrame.
The biodiversity reservoirs are represented in the same color, whether they belong to the Green Trame or the Blue Trame.
Regarding the Blue Trame, the rivers of the CARTHAGE© comic strip and wetlands of national importance 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, it is the Referential of Obstacles to the flow that is used.
