Threats to Posidonia

Threats to Posidonia Marine pollution The Posidonia oceanica It is highly vulnerable to water pollution, whether from sewage discharges, oil spills, or excess nutrients from agricultural runoff. These pollutants can alter water quality, reduce transparency and limit plant photosynthesis, causing its deterioration and a progressive loss of the underwater meadow. Anchoring and anchoring of boats The anchoring and anchoring of boats on the Posidonia meadows is one of the main threats to this plant. Anchors and chains damage and uproot the delicate rhizomes and roots, destroying the structure and continuity of the grasslands, which take decades to fully regenerate. Good practices Coastal Construction Activities Infrastructure and construction works in coastal areas, such as ports,, promenades and housing estates, lead to the direct destruction of Posidonia meadows. In addition, alterations in coastal dynamics and sediment inputs caused by these activities can suffocate and bury the plant, preventing its growth and development. Climate change and sea warming The increase in water temperature and ocean acidification, as a result of climate change, represent a serious threat to the Posidonia oceanica . These factors can disrupt the delicate ecological and physiological balances of the plant, reducing its ability to photosynthesize and grow, and making it more vulnerable to diseases and pests.
