Ecological surveys in Valence.

In Valence, the ecological stakes are concentrated on the Rhône and its alluvial plain: ripisylves, islands and lônes, associated wetlands, and a migratory corridor of major European importance. The Natura 2000 network sites linked to the river frame the review of riverside projects, and the presence of protected species tied to aquatic and riparian habitats calls for a thorough diagnosis before any development along the river. Our ecologists carry out four-season surveys, the ecological chapter of the impact assessment, the Natura 2000 impact assessment, wetland dossiers and the protected-species derogation application.

In Valence, 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 Valence

The area around Valence 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 Valence and its area to secure the project's regulatory timetable.
