Ecological surveys in Toulouse.
In Toulouse and its conurbation, urban sprawl over the hillsides, the corridors of the Garonne and its tributaries and numerous Natura 2000 sites and ZNIEFF make ecological survey work a structuring prerequisite for development. The 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 Toulouse operations.
In Toulouse, 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.
