Although Posidonia oceanica is strongly protected as a habitat and species under European and basic state legislation, the evident reality on the coast of the Balearic Islands means that this ecosystem has pressures and threats that endanger its good state of health. conservation, a fact supported by all scientific evidence
The main pressures are the occupation of the seabed for port works, dredging, illegal trawling, and the cumulative effect of the anchoring of boats, the discharge of poorly treated water and desalination brines or beach cleaning operations that involve the removal of Posidonia remains.
Threats include the increase in demographic and tourist pressure that has intensified in the last ten years; the threat of climate change, which implies an acidification of the seas and oceans; the dispersal of disease vectors, or the introduction of invasive species, among others.
It should be noted, regarding the listed pressures, that the removal of Posidonia dead leaves, as this specie it is included in the List of Species under the Special Protection Regime, must be regulated by the Administration; therefore, it is necessary to regulate this basic activity, in order to make it compatible with the conservation of the species
