Operation Posidonia: healing old wounds by restoring an endangered seagrass in boat mooring scars

Funded by the NSW Environmental Trust Restoration and Rehabilitation program 

This project uses recent innovations in seagrass restoration to revegetate an endangered seagrass, Posidonia australis, in boat mooring scars where environmentally friendly moorings have recently been installed. Donor seagrass shoots are collected by 'citizen scientists' following large storms, which result in naturally detached seagrass being washed-up along beaches.

This method of collection of donor shoots avoids damage to existing P. australis meadows while also engaging local communities in restoration. In parallel, a science communication campaign aims to raise awareness about the importance of seagrass meadows and the benefits of environmentally friendly moorings. Project knowledge will be transferred to volunteer groups to facilitate P. australis restoration in other NSW estuaries.
