Abstract

Corals are the framework builders of coral reefs and face a suite of global and local pressures. One prominent local pressure is dredging. This project has investigated the impacts of a large-scale dredging project on coral health, and performed laboratory experiments Investigating the specific causal pathways and thresholds values of sediment related pressures. Additionally, cumulative impacts of both locally (sediment) and globally-relevant (temperature) pressures were Investigated. The results demonstrate that dredging impacts upon coral health and that cumulative Impacts further reduce health. These results provide critical knowledge to Improve the future management of dredging activities near coral reefs.
