Join our Storm Squad

Because Posidonia is a protected species classified as ‘endangered’ in many NSW estuaries, one of the greatest challenges for restoration is finding donor shoots to revegetate the mooring scars.

Operation Posidonia has come up with an exciting solution to this problem, but it relies on getting help from local communities.

We are asking 'citizen scientists' to collect donor shoots from their local beach.

Living, green Posidonia shoots often wash ashore after storms, where they will soon perish unless returned underwater. Citizen scientists can collect these detached seagrass shoots and bring them to one of our collection spots. We will then use these shoots to restore seagrass populations without damaging existing Posidonia meadows.

We are aiming is to enlist the help of dog walkers and local beach-goers, who can join a local ‘seagrass storm squad’ and be part of the solution.

It’s all starting in Port Stephens

We are launching Operation Posidonia in Port Stephens, in central NSW. Scientists have selected this location because it represents one of the healthiest estuaries in NSW.

Although Posidonia is currently not threatened in Port Stephens, there are many boat mooring impacts in this estuary (2nd most of any estuary in NSW), with some mooring scars as large as 700 m2.

Port Stephens is also an ideal location because it is the headquarters of Fisheries, NSW Department of Primary Industries, who have led the development of the novel seagrass restoration methods used in this study.

We aim to develop a proof-of-concept restoration method that we can then apply to revegetate Posidonia meadows in  other estuaries, where there the species is endangered and there’s a risk it may become locally extinct.
