dc.description.abstract The frequency of disease within coral communities was evaluated using an 18-month series of coral photographs taken before, during, and after a major dredging program at Barrow Island, off Australia's northwest coast. Up to 60 corals were assessed repeatedly at each of four dredging 'impact' sites (< 1 km from dredging), and four 'reference' sites (> 20 km from dredging). Contrary to an earlier report, the frequency of occurrence of coral disease (usually < 5% of corals) was not significantly altered by dredging. The pattern of occurrence of coral disease does not constitute a suitable early warning bioindicator of dredging impacts on coral. This study suggests that disease is difficult to measure and evaluate, and is not a key indicator in the potential impacts of dredging on coral health. We propose that environmental monitoring during dredging should continue to focus on known impact indicators.
dc.description.sponsorship All data collection was funded by Chevron Australia as part of a compliance monitoring program associated with the Barrow Island dredging program.
