CEN Nouvelle-Aquitaine runs a network of 127 managers formed by farmers, foresters, local authorities, associations or individuals, for more than 1 037 ha. Membership of the network, courtesy and annual, takes place through the signing of an agreement. This prohibits drainage, fertilisation or modification of the land use of wetlands because these practices alter the environment too strongly: the utility and interest of wetlands for water resources and biodiversity are greatly diminished. This 2020-2021 project will continue the momentum for wetlands and increase the number of Network managers.
