Abstract

Flooding of the Mary River in early 2022 resulted in persistent flood plumes in the Great Sandy Marine Park (GSMP), leading to substantial impacts to seagrass meadows, and declines in dependent species including dugongs and green sea turtles. In response, the Queensland Department of the Environment, Tourism, Science and Innovation (DETSI) commissioned James Cook University (JCU) to conduct a series of post-flood assessments of seagrasses in Hervey Bay and the Great Sandy Strait funded by the joint Australian-Queensland government funded Disaster Recovery Funding Arrangements Environmental Recovery Program. Surveys were conducted in:

• May 2022 (York et al. 2022) during a typical low seagrass growth period

• October/November 2022 (Bryant et al. 2023) during a typical high seagrass growth period

• October/November 2023 (Bryant et al. 2024) assessing recovery 30 months post impact.
