Protecting posidonia meadows and keeping our marine environment healthy and full of life
The Mediterranean is one of the richest seas on the planet in terms of biodiversity and yet also one of the most threatened in the world. In Ibiza and Formentera, meadows of Posidonia oceanica seagrass play a crucial role in the health of the marine ecosystem: they capture carbon, filter the water, generate oxygen, protect beaches and host a wide diversity of species. However, tourism pressure, uncontrolled anchoring, pollution and climate change threaten their survival.
Ibiza & Formentera Preservation works to protect these ecosystems through scientific monitoring, environmental education, the promotion of good practice and partnerships with institutions and the local community.
Posidonia study
We support an annual study monitoring the condition of posidonia meadows in Ibiza, carried out by GEN-GOB in collaboration with the town halls of Ibiza and Sant Josep, as well as the “Xarxa Posidonia” of the Balearic Regional Government. The project, active since 2022, carries out field campaigns in the Bay of Talamanca and Cala Vedella and studies sea temperature changes via underwater thermometers, culminating in the publication of an annual report. According to the 2024 study, seawater temperature in the Bay of Talamanca exceeded 30 degrees Celsius in August 2023, adversely affecting the health of the posidonia. The report also warned that more than 50% of the meadow is dead in some areas and shows no sign of recovery. This information underpins conservation actions and policy advocacy, as well as raising public awareness about the impacts of inappropriate anchoring, declining water quality and climate change on this key ecosystem. This project has been supported by the womenswear brand Hoss Intropia since 2024.

Marine Forum & Future Forum
The Marine Forum of Ibiza & Formentera is a leading think tank that brings together international, national and local experts, as well as representatives from the public and private sectors and civil society, to discuss marine challenges and to develop proposals to protect at least 30% of the sea by 2030. Conceived of as space for multisectoral dialogue, the annual Forum seeks to promote effective policies, foster collaboration and increase environmental awareness. Its youth version, the Future Forum, is aimed at primary and secondary school students in Ibiza and Formentera and offers them the opportunity to reflect, learn and engage in active debate about marine conservation from an early age.
Ibiza & Formentera Preservation Blue Crime Classroom
The Ibiza & Formentera Preservation Blue Crime Classroom is an initiative in collaboration with the Jaume I University in Castellón, promoting teaching, research and outreach in the field of marine environmental crime. It is an innovative academic space that supports the training of future professionals and seeks to improve scientific knowledge about activities that adversely affect the marine environment. It also promotes academic work, organises conferences and seminars, and carries out awareness-raising activities in schools across Ibiza and Formentera.
Shark and ray study
The conservation of sharks and rays is key to the ecological balance of the Balearic Sea. However, many elasmobranch species are in decline due to fishing, habitat loss and lack of data about their distribution. In collaboration with GEN-GOB, Soldecocos, WWF España and the University of Alicante, Ibiza & Formentera Preservation supports a project that combines tagging of specimens in the waters around Ibiza and Formentera with innovative environmental DNA analysis. The aim is to improve scientific knowledge of these elusive species, identify areas of special ecological value and facilitate the adoption of more effective evidence-based management and conservation strategies.
Calant Xarxes
Illegal fishing and fraudulent marketing represent a serious threat to the sustainability of the Balearic Sea. The Calant Xarxes Alliance (“casting nets” in Catalan) tackles this issue through a comprehensive approach, working across the entire value chain: from supporting fishers and distributors to encourage sustainable practices, to raising awareness among the public and restaurants in order to promote responsible consumption of Balearic seafood. In collaboration with the Marilles Foundation, the Conservation Collective, and the Mallorca Preservation and Menorca Preservation foundations, the project promotes the traceability of seafood products, reviews existing control mechanisms, and develops educational materials that strengthen transparent and sustainable co-management of fishery resources — such as the Sustainable Seafood Consumption Guide for the Balearic Islands..

Formentera Dive Camp
Between 2019 and 2024, we co-financed the Formentera Dive Camp, run by Vellmarí Association, which promotes environmental education among young people through direct contact with the sea. Over six years, we funded nearly 400 scholarships, mostly for people in situations of social vulnerability, who were able to explore marine biodiversity first-hand and take part in workshops on Posidonia oceanica, marine fauna and the impact of plastics and microplastics. We are pleased to have contributed to this initiative, which combines awareness-raising, social inclusion and educational action to foster a new generation committed to marine conservation.
