Ecological surveys in Paris.

In Paris and the inner suburbs, the Seine and its banks, the large parks, the railway land and the Île-de-France Natura 2000 sites shelter a protected urban biodiversity that shapes the feasibility of projects. Wetlands, ecological continuities (the green and blue infrastructure of the SDRIF) and protected species call for rigorous surveys, including in a very urban context (buildings, brownfields, roofs). Our ecologists carry out four-season fauna and flora surveys, the VNEI, the Natura 2000 impact assessment and the CNPN application, managing the Avoid-Reduce-Offset mitigation hierarchy, for operations in Paris and across the Grand Paris.

In Paris, the wealth of natural habitats (Natura 2000 sites, ZNIEFF, protected species) makes ecological survey work a structuring prerequisite for development. Four-season surveys, VNEI, CNPN application and the mitigation hierarchy secure environmental authorisation and planning permission.

FAQ

FAQ, ecological surveys in Paris

The area around Paris concentrates high biodiversity stakes (Natura 2000 sites, ZNIEFF, protected species and habitats). As soon as a project is likely to affect natural habitats, an ecological survey conditions the environmental authorisation, the impact assessment and the planning permission: fauna and flora surveys over a full biological cycle, impact assessment and the Avoid-Reduce-Offset mitigation hierarchy.
Yes: fauna and flora surveys across the four seasons, ecological chapter of the impact assessment (VNEI), Natura 2000 impact assessment, and protected-species derogation application (CNPN) with the definition and monitoring of ERC measures. Our ecologists work in Paris and its area to secure the project's regulatory timetable.
