Ecological surveys in Lyon.
In Lyon and its metropolitan area, the confluence of the Rhône and the Saône, the river corridors, the wetlands and numerous Natura 2000 sites and ZNIEFF make ecological survey work a structuring prerequisite for development. Urban pressure on the last peri-urban natural spaces calls for rigorous fauna and flora surveys before any project. Our ecologists carry out the ecological chapter of the impact assessment, the Natura 2000 impact assessment, the protected-species derogation application (CNPN) and the management of the Avoid-Reduce-Offset mitigation hierarchy, to secure the environmental authorisation of Lyon operations.
In Lyon, 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.
