Ecological surveys in Bayonne.

In Bayonne and along the Basque coast, the wealth of coastal and estuarine habitats (Adour, Nive) and of wetlands, protected under Natura 2000, ZNIEFF and the Coastal Act (loi Littoral), makes ecological survey work an unavoidable prerequisite for development. Protected species, ecological corridors and sensitive habitats call for rigorous surveys upstream to secure the impact assessment, environmental authorisation and planning permission. Our ecologists carry out fauna and flora surveys across the four seasons, the VNEI, the Natura 2000 impact assessment and the CNPN application, managing the Avoid-Reduce-Offset mitigation hierarchy, for operations in Bayonne and across the Basque Country.

In Bayonne, 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.
