Seagrasses in Port Curtis and Rodds Bay 2023 Annual long-term monitoring.

Seagrass monitoring in Port Curtis and Rodds Bay commenced in 2002 and has been conducted annually since 2004. Fourteen monitoring meadows are assessed annually, and the condition of the meadows evaluated based on variations in three key seagrass metrics - biomass, area and species composition. The current program has been developed to meet Gladstone Port Corporation’s obligations pertaining to the Long-Term Maintenance Dredging Management Plan and includes annual mapping and monitoring of 14 coastal seagrass monitoring meadows and five-yearly mapping of all coastal and deep-water seagrass in Port Curtis and Rodds Bay. Monitoring meadows represent the range of different seagrass community types in Port Curtis and Rodds Bay (Figure 1) and every five years all seagrasses within the greater port limits are reassessed (last done in 2019).
