In the period 2019-2022, CEN Auvergne proposes to implement a set of actions to preserve the green and blue frame of the Alagnon watershed. This project is structured around 4 main actions related to the preservation of wetlands and pres-vergers. With regard to the blue frame, provision is made, through the Technical Assistance Cell, to advise wetland managers of the territory. It is also planned to work on networks of pools and lime lakes which are small wetlands but whose mesh size on the territory is essential for the preservation of many species. This action will consist of improving knowledge of these environments but also preserving and carrying out work on sites identified as priorities. Among them is that of Lake Lorlanges, on which CEN Auvergne has been involved since 2005 in connection with the municipality. Finally, one last action concerns the pre-verger frame, as previously, this action will improve knowledge of these environments, including an inventory and characterisation phase of the sites, but also operational actions to preserve and restore this frame with the planting of new orchards and the conservation of old fruit varieties.
