Injured corals were more
susceptible to skeletal eroding band disease only at high use sites, suggesting that additional stressors
associated with use intensity facilitate disease development.
 Sediment necrosis of coral tissues was
strongly associated with the prevalence of white syndromes, a devastating group of diseases, across all
sites. We did not find significant differences in mean levels of coral growth anomalies or black band disease
between high and low use sites. Our results suggest that several indicators of coral health increase
understanding of impacts associated with rapid tourism development. Identifying practical management
strategies, such as spatial management of multiple reef-based activities, is necessary to balance growth of
tourism and maintenance of coral reefs.
