This page outlines the importance of seagrasses and what measures you can take to help preserve seagrass beds.

Seagrass beds provide food and shelter to a wide variety of fish and invertebrates. They also help bind the sea floor and improve water quality.

Seagrass has already been lost in some areas through the effects of water pollution, foreshore development and the recreational and commercial use of our waterways. You can help to preserve our seagrasses by adhering to the following:

  • Do not drive your boat across shallow, weedy areas, as boat propellers and jet propulsion units may damage seagrass
  • Do not anchor on seagrass beds. These are often indicated by darker patches on the sea bed
  • If you need to replace your mooring and it is currently over a seagrass bed, contact your local Transport for NSW office to discuss other options.

Transport for NSW is currently trialling seagrass friendly moorings in an attempt to minimise the impact of boating on seagrass beds. The Department of Primary Industries is also undertaking an inventory of seagrasses in NSW which will assist in identifying appropriate mooring areas and help to determine where anchoring will not damage seagrasses.

If you would like to find out more information in relation to seagrass and traditional boat moorings in sensitive habitats, please see the Department of Primary Industries website links:
