Sydney Harbour’s natural beauty is thanks to its healthy ecosystem, say Sydney researchers—and it’s one of the most diverse harbour ecosystems in the world.
“Sydney Harbour has over 3000 species of fish, plants, molluscs and other marine life,” says Paul Gribben, deputy director of the Sydney Institute of Marine Science (SIMS) Sydney Harbour Research Program.
“A lot of the harbour species are filter feeders and they’re important in keeping the water clear and removing excess nutrients and pollutants. Without this biodiversity, the harbour would be much more stressed and have much poorer water quality.”
The past, present and future of Sydney Harbour and its marine ecological mysteries will be explored by Paul and his colleagues A/Prof Emma Johnston and Prof David Booth, at an Ultimo Science Festival public lecture on Thursday August 16.
“Sydney has a very large human population around the harbour itself, but despite that, it continues to support this very diverse community with a large range of species.”
The SIMS Research Program is focused on how to make the harbour more resilient to climate change, urbanisation and other challenges, Paul says.
Paul, Emma and David will give an Ultimo Science Festival public lecture at 6pm, Thursday 16 August, at the University of Technology, Sydney (UTS) Great Hall, 15 Broadway, Ultimo.
About the speakers
Dr Paul Gribben
Paul Gribben is a Research Fellow with the UTS Plant Functional Biology and Climate Change Cluster, and Deputy Director of the SIMS Sydney Harbour Research Program. He’s a marine community ecologist who investigates the effects of man-made stressors on biodiversity.
Professor David Booth
