A study by the Guadeloupe National Park reveals that 87% of its coral reefs are affected by the proliferation of macroalgae, a clear indicator of poor coastal water quality.
Conducted between 2023 and 2024, the study assessed the health of coral reefs across 134 sites. Only 13% of coral communities were found to be in excellent health, while 58% were classified as healthy but coexisted with macroalgae.
More concerningly, 28% showed significant algae colonization or sedimentation, and 1% were found to be destroyed. Improving the quality of coastal waters, which are impacted by pollution from organic matter and nutrients, is essential to halt the decline in the health of Guadeloupe’s coral reefs.
