Seagrass is the unsung hero of the Great Barrier Reef.
Covering a vast area bigger than the coral reef itself, seagrass meadows along the Wet Tropics coast provide important habitat for prawns and fish and act as a filter for nutrients and sediment. Seagrass is also important for carbon sequestration.
TropWater's Dr Michael Rasheed is an expert in seagrass ecology and has been conducting research into tropical marine habitats for over 20 years.
In this podcast he discusses the many functions of seagrass in the Great Barrier Reef marine ecosystem and why it is a good indicator of waterway health.
