The Mediterranean monk seal, Monachus monachus, is one of the most endangered marine mammals in the world. In total, the population is estimated at less than 800 individuals. This is still an alarmingly low number, but a clear improvement since the situation in the 2000s, thanks to strong mobilization of various actors. Despite the tools developed, efforts have lacked coordination and continuity. Many action plans remain on paper and funds are allocated sporadically. In light of this, the Monk Seal Alliance was launched in April 2019, to bring together funders (foundations and donor organisations) to increase the scope of the activities carried out by monk seal conservation specialists in the field and allow for concerted, long-term and region-wide implementation of actions. The session will present the issues the species is facing and the actions of the Monk Seal Alliance, trying to build new partnerships for its conservation.
