Abstract:
Following the coral bleaching event in 1998, shallow reefs of Sri Lanka have undergone major changes with little signs of recovery. Changes in coral composition, substrate and coral susceptibility following bleaching event were studied using standard procedures over three years at the reef lagoon of the Hikkaduwa Nature Park. Coral mortality averaged 81% with higher mortality rates in the Acropora formosa dominated reef area. Acroporids were the most susceptible coral recorded with different species showing different degree of resilience. Mortality of the faster growing species followed a change in the composition of the coral communities that existed. The shifts in substrate dominance from coral to increased expanses of rubble and rock were recorded. From this study predictions on the future of shallow reefs of Sri Lanka affected by bleaching were made and the importance of proper future management of these ecosystems were brought to the forefront.
