Ecological surveys
Versailles, Île-de-France

In Versailles, the ecological wealth stems from the continuity between the estate, its ornamental ponds, the urban parks and the surrounding state forests, a whole that forms an exceptional biodiversity reservoir in the Île-de-France context. The remarkable trees and historic tree-lined avenues are protected on two counts, both heritage and ecological. The old building stock, very much present, also shelters bat colonies that must be searched for before any work on roofs or lofts. Our ecologists carry out the surveys, the ecological chapter of the impact assessment and the protected-species derogation application.

In Versailles, 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.
