Seagrass restoration project

Posted on Tuesday 23 August 2022

Environmentally minded residents can learn more about how they can help restore local seagrass meadows through joining Operation Posidonia which aims to restore Posidonia australis, a slow-growing seagrass that forms important foundation habitats around Mosman’s shorelines.

The seagrass was previously common in urbanised estuaries, such as Sydney Harbour, where it is now endangered, and the restoration aims to give nature a helping hand by restoring lost seagrass one patch at a time.

Learn more about the project and how to get involved at the launch of the operation’s Balmoral pilot project which is supported by Mosman Council, Sydney Institute of Marine Science and UNSW on Saturday 10 September from 10am to 12pm. Visit to register to attend.
