Statton, J., McMahon, K., McCallum, R., Kendrick, G., & Lavery, P. (2017). Sediment burial stress response, bio-indicators and thresholds for a tropical multi-species seagrass assemblage: Report of Theme 5-Project 5.5. 2 prepared for the Dredging Science Node, Western Australian Marine Science Institution, Perth, Western Australia, 38 pp.


Deterioration in water clarity by resuspension of dredged sediments is presumed to be a major mechanism by which dredging can impact seagrasses. This report presents findings from a controlled light experiment that aimed to determine the effects of low light stress on the growth of three seagrass species found in the northwest of Western Australia.


  • To determine the effects of sediment burial stress under dredge-simulated conditions on the growth and health of three seagrass species found in the northwest of Western Australia.
  • Provide guidance and protocols for the application of the research outputs (e.g. seagrass burial stress:response relationships, sub-lethal and lethal bio-indicators and thresholds) to the prediction, assessment, monitoring and management of dredging programs in northwest of Western Australia.
