Community-based conservation empowers local people in the management process through partnerships in planning and implementation of conservation projects in the hopes of creating accountability and ownership of conservation objectives. We have taken this concept a step further, using the principles of community-based conservation in the planning, implementation and monitoring of a wetland restoration project in Camargue (southern France). The Tour du Valat (scientists and landowner), with active collaboration from a local community, has recovered 120 ha of natural wetlands that had been converted into fish farming. The conservation objective was to recover the principle habitats traditional to the Camargue with a move from artificial marsh exploitation with high, continual water levels to a more “natural management” with seasonal fluctuations in water levels. The results of the participatory monitoring have shown a return of traditional flora and fauna, with the recovery of permanent and temporary marshes, reed beds stands, pastoral vegetation and bush lands. The project evaluation showed that stakeholders appreciated their involvement in a co-learning process where habitat management, plant ecology, local uses of plants and game birds were discussed in depth with scientists and villagers. The recovered land now hosts a variety of multi-use activities for the villagers including grazing, hunting, fishing, hiking, bird watching and educational visits. Now, six years after the initiation of the project, we have shifted from a community based restoration project to a joint community managed project.
