NESP Marine and Coastal Hub (2021). The role of dugong and turtle grazing in Torres Strait seagrass declines. Project 1.14 Information sheet. Reef and Rainforest Research Centre, Cairns, Queensland.



Dramatic declines in seagrass meadows in the Torres Strait Western Cluster were recorded in 2019 and 2020. These meadows are culturally important and represent significant foraging grounds for green turtles and dugongs. This project will use a short-term field study to investigate the role of megaherbivore grazing in two key locations where seagrass declines have been most dramatic. This project has been co-developed with the Torres Strait Regional Authority (TSRA), Sea Rangers and Goemulgaw PBC in response to community concerns about seagrass declines and the implications for the totemic megaherbivores they support. The results will inform Traditional Owner led dugong and turtle management plans and help direct actions for remediation as required.
