[email protected] www.gbrmpa.gov.au ii Tropical Cyclone Risk and Impact Assessment Plan — GBRMPA Executive summary Waves generated by tropical cyclones can cause major physical damage to coral reef ecosystems. Tropical cyclones (cyclones) are natural meteorological events which cannot be prevented. However, the combination of their impacts and those of other stressors — such as poor water quality, crown-of-thorns starfish predation and warm ocean temperatures — can permanently damage reefs if recovery time is insufficient. In the short term, management response to a particular tropical cyclone may be warranted to promote recovery if critical resources are affected. Over the long term, using modelling and field surveys to assess the impacts of individual tropical cyclones as they occur will ensure that management of the Great Barrier Reef represents world best practice. This Tropical Cyclone Risk and Impact Assessment Plan was first developed by the Great Barrier Reef Marine Park Authority (GBRMPA) in April 2011 after tropical cyclone Yasi (one of the largest category 5 cyclones in Australia’s recorded history) crossed the Great Barrier Reef near Mission Beach in North Queensland.
