Due to major developments over the past two centuries, the Eau Morte Valley (a tributary of Annecy Lake) has a hydrosedimentary dysfunction with incised areas and areas with sediment excesses and an alluvial marsh disconnected from flooding. To reduce the impacts of the river's floods on uses, and to prevent the risk of urban areas flooding, a functional restoration programme for the valley has been developed by the federation of municipalities of Annecy lake sources. It was based on the renaturation of the Eau Morte bed, the functional restoration of the Giez marsh and the construction of crossing structures. This work has given the marsh a role as a flood expansion area. This project was also carried out by involving local residents in a process of territorial dialogue so that they themselves would be actors in the area and would participate in its management.

Since 1984, the Hunting Federation of Ille-et-Vilaine Department has been rehabilitating a 550-hectare marshland that was heavily developed in the last century. Rehabilitation began with the replacement of corn crops by hay and pasture natural meadows via contractual agreement (with finacing) with the farmers. It continued with the restoration of a peat bog and a reed bed. In addition, due to the highly developed nature of the marsh and its drainage by a highly recalibrated and deepen watercourse, artificial water level management was also put in place to allow winter flooding. The project's objective is to improve the marsh to allow migratory waterbirds halting and to improve some of the marsh functionalities (carbon sequestration by peat and natural water purification). They have been achieved with regard to bird halting, but water level management is not currently optimised and will be reviewed to improve the hydrological functioning of the marsh.

More than half of the territory of the regional natural park of the Millevaches in Limousin (PNR) is covered with forest, some of which is the subject of intensive forestry exploitation. A peat bog restoration project in the headwater sector of the catchment area was initiated between the PNR (project manager) and the forestry cooperative Bourgogne Limousin (technical partner). The goal was to remove the softwood stand from the single-species plantation on the plot in order to restore the hydrological functioning of the peat bog. The work was carried out by aerial skidding using a cable mast. In addition to initiating collaboration between forestry and environmental management, the project has made it possible to restore the natural hydrological functioning of the bog and the associated specific habitats.
