On 21 August 2026, the foundation Ibiza & Formentera Preservation criticised the fact that only 18 formal reports were filed for anchoring over Posidonia on Ibiza and Formentera in 2025, despite the monitoring service recording 4,813 such cases in total. That amounts to a rate of 0.37 per cent, or one report for every 270 recorded infringements. According to the foundation, the figures are based on data from the Dirección General de Medio Natural and an analysis by its own Observatorio de Sostenibilidad.
According to the foundation, 15 of the 18 cases were in Ibiza and three in Formentera. The cases were recorded by the Servicio de Vigilancia de la Posidonia of the Conselleria de Medio Ambiente y Territorio. In Ibiza & Formentera Preservation’s view, the discrepancy between documented anchoring cases and proceedings initiated points to gaps in enforcement; it is therefore calling for more environmental officers and additional monitoring resources, specifically in the Pitiusas.
Official figures show that the government of the Illes Balears (Govern) operates the monitoring service through the Institut Balear de la Naturaleza (IBANAT) and reported more than 181,000 deployments during the 2025 season. For the current 2026 season, the Govern has announced a strengthened operation in the Pitiusas, with several boats and technical upgrades. The authorities regularly emphasise preventive checks and the redirection of boats away from protected areas; however, how many recorded cases ultimately lead to fine proceedings depends on further steps in the process.
The issue concerns the protection of the seagrass species Posidonia oceanica, whose meadows cover extensive stretches of the Balearic coastline. They dampen waves, stabilise sediment, store carbon and provide nursery grounds for many marine species. In addition to direct damage from anchors, rising sea temperatures are also a source of pressure. Ibiza & Formentera Preservation cites regional studies suggesting that several beds on Ibiza are deteriorating.
The administrative information on which the foundation’s figures are based does not explain the specific reasons for the low number of formal reports in 2025. Possible explanations – such as staff shortages, fieldwork priorities or legal obstacles – are presented by the foundation as assumptions. The competent authorities decide on binding penalties; reliable figures will be available only once the relevant proceedings have concluded.
The debate therefore touches on the balance between widespread prevention at sea and the consistent prosecution of clear infringements. Whether the reinforcements to the monitoring operation announced for Ibiza and Formentera in 2026 measurably increase the enforcement rate will become clear only after the current season has been assessed.
