| الوصف: | Introduction: Coral reefs are biodiversity-rich ecosystems increasingly threatened by disease and, in particular, mass bleaching events driven by elevated sea-surface temperatures. Objectives: To assess spatio-temporal variation in reef structure and coral health across three reef zones within Tayrona National Natural Park (TNNP) from 1998 to 2023. Methods: Coral cover (CC), algal cover (AC), and coral health (CH: bleaching and diseases) were quantified following the protocols of the Colombian Coral Reef Monitoring System. Results: In Gayraca, mean CC was 37.05 %, dominated by massive corals with a declining trend. Mean AC was 43 %, and turf algae increased significantly through time. Black band disease and white plague were recorded with < 2 % incidence. In Chengue, mean CC was 30 % (massive corals), with disease incidence around 2 %, and the mean AC was 44 %. In Granate, mean CC was 28.2 %, largely massive corals with a downward trend, while mean AC was 47 %, dominated by turf algae with an increasing trend. Stony Coral Tissue Loss Disease (SCTLD) was not detected. Conclusions: Bleaching increased sharply in 2023, reaching unprecedented levels. Across bays, we observed a tendency toward lower CC and higher AC in areas closer to human populations. Although disease prevalence across years was high, annual disease incidence remained low and did not track thermal stress, suggesting comparatively high biological robustness of local coral populations. |
