Wetlands – Ecological Corridors (SRCE)

This dataset lists the various **potential ecological corridors** for the **subtrame** ** wet middle** of the SRCE in the Centre-Val de Loire region. These corridors provide connections between reservoirs of biodiversity, providing species with favourable conditions for their movement and completion of their life cycle. (Article R.317-19 III of the Environmental Code). Two levels of intervention are possible under the CERS: corridors to be restored and those to be preserved. An indicative right-of-way of 3 km should be taken into account on either side of the corridor axis, so as to indicate that they are impreciable movement zones that should be refined from local knowledge. at the time of declination of the SRCE. The regulations allow that not all biodiversity reservoirs are necessarily connected by ecological corridors (Article R.317-19 II of the Environmental Code). This scenario should be limited and mainly concern biodiversity reservoirs with regard to: * a) the relevance of connecting or maintaining the natural isolation of these spaces (in particular: cases of isolation to prevent the spread of invasive alien species or potential health problems posed by wildlife carrying diseases that can be transmitted to domestic species (e.g. swine fever) or even humans (e.g. rage)). * B) the challenge of preserving certain areas that constitute an ecological network in “not Japanese” for the associated species (e.g. ponds and lakes, ponds, peatlands) or certain areas not connected today but that can serve tomorrow as a “relay” or a new point of the ecological mesh of the territory (faced with changes such as climate change, the evolution of the range, fires, the disappearance of reservoirs via a development project...).
