The project aims at developing a joint cross-border strategy for maintenance of biodiversity and conservation of the population of Caretta caretta, a sea turtle species seriously threatened by the impact of human activities. The project foresees these main actions:
• Development of a Management Model for marine areas (handbook)
• Management Plans for the Marine areas involved, through elaboration of bathymetric and habitat maps, identifying stress factors
• Implementation of a GIS to share information resulting from maps setting a Tank of First Recovery for the protection of Caretta caretta, in the centres of protected areas involved
• A Database collecting information on survey coasts report, areas of potential nesting; biometric data, web GIS movements of the 20 specimens paths through ARGOS satellite system
• An Action Plan for the protection of the population of sea turtles
• A cross-border Association providing exchange of expertise and the identification of joint objectives for biodiversity conservation.
