Lawns and dry edges on limestone soils — Ecological Corridors (CESR)

This dataset lists the various potential ecological corridors for the subtrame lawns and dry edges on the SRCE limestone soils in the Centre-Val de Loire region. These corridors provide connections between biodiversity reservoirs, providing species with favourable conditions for their displacement and completion of their life cycle. (Article R.317-19 III of the Environmental Code). Two levels of intervention are possible under the SRCE: corridors to be restored and those to be preserved. An indicative 3 km right-of-way is to be taken into account on both sides of the corridor axis, so as to clearly indicate that they are imprecise displacement spindles to be refined from local knowledge. at the time of declination of the SRCE. The regulations allow that not all biodiversity reservoirs are bound by ecological corridors (Article R.317-19 II of the Environmental Code). This scenario should be limited and mainly concern reservoirs of biodiversity 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 possible health problems caused by wildlife carrying diseases that can be transmitted to domestic species (e.g. swine fever) or even man (e.g. rage)). * B) the issue of preserving certain spaces that constitute an ecological network in “not Japanese” for associated species (e.g. ponds and lakes, ponds, peat bogs) or some areas not connected today but which can serve tomorrow as a “relay” or as a new point in the ecological mesh of the territory (in the face of changes such as climate change, the evolution of the range, fires, the disappearance of reservoirs via a development project...).
