Cleveland Bay Monitoring

Monitoring Seagrass Health in Cleveland Bay

Seagrass communities’ health is one indicator that reef managers can use to understand the overall health of the marine environment. Port of Townsville Limited commissions an annual Seagrass Health Survey in Cleveland Bay which is carried our by James Cook University's Centre for Tropical Water & Aquatic Ecosystem Research (TropWATER). 

The annual survey maps areas of seagrass meadows as well as species types and density. Surveyors from JCU record observations at hundreds of sites in Cleveland Bay and track changes over time.

The 2018 Annual Seagrass Survey results for Townsville and Cleveland Bay showed:

  • The overall condition of the seagrass in Townsville was classed as good in 2018
  • Above-ground biomass remained in good or very good condition at all ten monitoring meadows.
  • Dugong feeding trails were observed at the inshore meadows at Shelly Beach, Rowes Bay and Pallarenda.  Indicating a relative high use of these seagrass meadows by dugongs.
