Ecological surveys in Saint-Étienne.

In Saint-Étienne, ecological survey work covers a territory undergoing regeneration, where abandoned industrial and mining brownfields have often developed spontaneous, sometimes noteworthy biodiversity, which frequently surprises project owners who regarded them as sites of no concern. The proximity of the Pilat regional nature park and the corridors linked to the basin's watercourses also structure the ecological continuities. Our ecologists carry out fauna and flora surveys over a full biological cycle, the ecological chapter of the impact assessment and the protected-species derogation application.

In Saint-Étienne, 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.
