Seagrass restoration

Cobblers Beach in Mosman has become the first location in Sydney Harbour to host a site for the restoration of endangered seagrass. 

It follows a concerted community effort, led by Mosman Council, to revive the vital marine environment. 

In a partnership between Council and the Sydney Institute of Marine Science (SIMS), underwater plots of Posidonia australis seagrass have been planted at Cobblers Beach. 

Seagrass fragments, some of which were collected by community members after being washed up after storms, were harvested at the SIMS headquarters in Chowder Bay. 

Hundreds of specimens have now been planted off the Cobblers Beach coastline to support marine life, including seahorses. 

Results will be monitored, with potential for the project to expand to other harbour locations.
