GREAT BARRIER REEF
// Outlook Report 2014
Managing for resilience is most important in situations where there is uncertainty about risks and appropriate management responses. 32 Mitigating and minimising the multiple impacts that affect an ecosystem will improve its overall resilience. Managing agencies, industries and communities can all play a role. For example, where fishing and tourism operators on the Great Barrier Reef and landholders in the catchment practise strong stewardship, pressures are reduced and Reef health and resilience is supported. 33
8.3 Case studies of recovery in the ecosystem
Although recovery after disturbance is only one aspect of resilience, it is a critical attribute of a resilient system, is practical to measure and monitor, and gives an indication of overall resilience. The series of case studies below illustrate the extent to which some key components of the ecosystem have recovered after disturbance. They provide evidence of the overall resilience of the Great Barrier Reef ecosystem. The case studies showcase a range of aspects relevant to resilience: • the extent to which some key functional habitats have responded after human and natural disturbances — coral reef and lagoon floor habitats • the extent to which some key ecological processes have responded after human and natural disturbances — black teatfish (particle feeding), urban coast dugong (herbivory) and coral trout (predation) • the effectiveness of specific management actions implemented to address declines in specific species — loggerhead turtles and humpback whales. The case studies are the same as those in the Outlook Report 2009 so that trends over time can be analysed and reported.
