About us

Committed to the future
of the Balearics

We are a foundation dedicated to the conservation of the Balearic Sea and coast and we believe that healthy marine ecosystems can be reconciled with economic prosperity. Our core costs are covered by Adessium Foundation so every euro donated to Marilles supports live projects directly linked to the conservation of the Balearics.

Our History

Marilles was officially founded in 2017, but the research and planning behind the organisation began earlier. We have a robust network of partners in the Mediterranean and beyond with long roots in environmental philanthropy.

Our History

Where Marilles came from

In 2015, the Adessium Foundation commissioned a study which identified the Balearics as one of the healthiest and best-preserved marine environments in the Mediterrean, but one which was under growing threat. Two years of local research and liaison made clear that rapid action to conserve the region would have an excellent chance of success. Marilles was founded to help meet this need.

Our mission was soon endorsed by the substantial support of MAVA Foundation, the largest and longest-established funder in the Mediterranean. In 2019, the Flotilla Foundation joined the initiative. The expertise of these organisations has been critical to ensure robust internal systems and efficient operation at Marilles.

Co-ordinating effort is key to our approach to tackling the issues involved. Our priority is to facilitate dialogue between NGOs, experts, government and the private sector to try and ensure that all their efforts are strategically aligned.

Together, we are stronger in facing the sea’s challenges.

The way we work

Marilles’ approach is positive, inclusive and above all focused on finding solutions.



We believe that reconciling marine conservation with economic prosperity is demonstrably achievable. Our experience shows that a positive approach engages and energizes, encouraging
people to take action.



All sectors of society – public, private and civic organisations – have roles to play in the conservation of the Balearic Sea. We consult with fishermen, nautical clubs, hotels, research centres, diving centres, NGOs and public institutions to co-ordinate all efforts for maximum impact.



Our emphasis is on finding and designing solutions and putting them in motion. We extensively consult, listen and analyse to ensure our understanding of key problems. Once these are established, we focus entirely on tackling them.

She has a PhD in marine sciences and many years of research experience, with a particular focus on marine biogeochemistry and Posidonia. In her own words: “Seagrass meadows are like a second home to me.
