The aim of the project is the comprehensive inventory (delimitation) of wetlands, the hydrographic network, water bodies and hedges and their typological and functional characterisation to supplement the level of knowledge of biodiversity and natural habitats in order to include them in the Green and Blue Trame and protect them through the local intercommunal urban planning plan (PLUi) of the Bocage Bressuirais agglomeration community. By taking into account wetlands, the hydrographic system, water bodies and hedges, the community strives not to compromise the quality of its environments in its development choices (urban or economic). It thus responds to the principle of sustainable development.
