The Gunggandji-Mandingalbay Yidinji (GMY) Land and Sea Rangers have been working alongside scientists to better understand the ecological significance of coastal and deepwater seagrass meadows within their sea Country. Building upon successful GMY-led reef and seagrass baseline mapping and monitoring, this project integrates traditional knowledge with a scientific approach to explore the biodiversity and the trophic pathways that support and connect our sea life. Through stable isotope analyses of multiple trophic levels, combined with satellite and acoustic tracking of culturally significant megafauna, we aim to clarify the role of seagrass habitats in sustaining our totem species and the fishery species we depend on. This project emphasises ranger upskilling in scientific methods, including food web analysis and animal movement tracking. Data generated will contribute to nationwide statistics on megafauna movements and their connections to blue carbon habitats, addressing knowledge gaps in tropical seagrass food web dynamics. For our community, this project helps build a connection between the value of our marine landscape and the animals who rely on its health and function.
