These are ecological management operations of lawns, bat cavities and heaths with high ecological and remarkable challenges at regional and European levels. The aim of this project is not only to protect and restore biodiversity, but also to enhance the landscape and indeed the living environment of the inhabitants of the area concerned. In addition, as part of the implementation of this programme of actions with the ecological management of sites as a support, the Conservatoire d’Espaces Naturels de Picardie (CENP) is setting up partnerships with local farmers, rehabilitation associations, medical and sports institutes and high schools, among others.
