Background AMV (the project beneficiary) is developing and coordinating a colonial Charadriiformes (gulls and waders) conservation programme along the French Mediterranean coastline, where populations of these EU Birds Directive-listed species are in decline. This decline is mainly attributed to poor reproductive success due to the poor quality of nesting sites. After some preliminary studies, pilot actions have been carried out since 2007, with the first measurable positive outputs recorded in 2011. Simple conservation actions (nesting islet restoration and raft building, adapted hydraulic management) have demonstrated positive impacts on reproductive success. The constituted management network has now been enlarged for a second action plan, which integrates new public and privately owned areas. Objectives The overall objective of the LIFE+ ENVOLL project is to improve the conservation status of colonial Charadriiformes species listed in the Birds Directive in 9 Natura 2000 sites along the French Mediterranean coast. This general goal will be achieved by: Managing and improving all project sites in order to enhance conditions for colonial Charadriiforme nesting (hydraulic work to manage water levels, islet and raft design, etc.); Improving knowledge in order to improve conservation management techniques; Enlarging the management and monitoring agent networks; Monitoring and evaluating the project’s impact over the entire targeted area (i.e., assessment of the impact on colonial Charadriiformes, as well as the socio-economic impact); Raising awareness among the general public and site users through an education programme focused on colonial Charadriiformes; Sharing the project results and outputs (international workshops, international seminar, coordination with other LIFE projects) during and after the project. Expected results: At least 50% of the managed sites will have been used at least once during the project by colonial Charadriiformes for nesting; Reproduction success will be better on managed sites than on non-managed sites; The 9 Natura 2000 sites will have benefitted from conservation management, with 23-38 islets created or rehabilitated, 6 rafts installed, and 435 ha with restored hydraulic conditions; Awareness will have been improved through the various education and communication activities; Results and outputs will have been shared as a result of four training courses and two management booklets; and one international seminar; The project actions will have been designed to maximize their sustainability, the networks will be self-sustaining after the project and new conservation techniques (training tools, management guidelines) will have been learned or acquired.
