NESP TWQ Round 2 - Project 2.1.6 - From exposure to risk: novel experimental approaches to analyse cumulative impacts and determine thresholds in the GBRWHA

Region map

Understanding cumulative impacts from multiple stressors is critical for successful management of the GBR under the Reef2050 Plan. The project produced experimental analyses of concentration-response relationships for selected species under broad, controlled envelopes of sediments, turbidity, nutrients, light, salinity and temperature. Based on new understanding of threshold exposure values, existing and new field data the project has enabled exposure maps for individual stressors to be produced and exploratory techniques to summarise those into cumulative exposure maps. Results have informed spatial and temporal assessments of ecological risks, and management opportunities for a range of activities in the coastal zones and inshore GBR waters.
