The SAMESEA project aims to standardize and harmonize marine ecosystem monitoring throughout the EUSAIR (EU Strategy for the Adriatic-Ionian Region) basin. By promoting dialogue and collaboration between socio-economic stakeholders and authorities responsible for marine conservation, the project seeks to tackle the challenges posed by human pressures on marine biodiversity. A key project focus will be the monitoring of sentinel species such as the loggerhead sea turtle (Caretta caretta), bottlenose dolphin (Tursiops truncatus) and Mediterranean monk seal (Monachus monachus). The development of a Transnational monitoring strategy will help guide sustainable practices and reduce human impact on these vulnerable species. Furthermore, a SAMESEA Network will be established to strengthen collaboration among national and regional entities, supported by a regional task force dedicated to the conservation of sentinel species. Morigenos plays a vital role in the data collection for this project and actively participates in its pilot testing, by developing monitoring protocols and management strategies to support the conservation of sentinel species. Additionally, Morigenos is engaged in capacity building, collaborates closely with stakeholders, and is responsible for communication efforts.
