After several years of collaborative work, the national wetland mapping project in mainland France is reaching the end of its second phase. This project is led by PatriNat in partnership with the University of Rennes 2 and the Tour du Valat.
To mark the occasion, a feedback seminar was held on Thursday 26 March 2026 to share recent findings, methodological developments and prospects for using the data to support research and management policies. The proceedings of this seminar and the video recording are now available.
