From July to September 2025, Indigenous rangers from Queensland, the Northern Territory and Western Australia joined researchers to film a series of seagrass monitoring activities for NESP Hub project 5.2. The fieldwork took place in the Kimberley (WA), southern Gulf of Carpentaria (NT), central Great Barrier Reef (QLD) and Torres Strait, documenting how rangers use different techniques to monitor the health of vital seagrass meadows, including drone mapping, underwater camera surveys from boats and intertidal transect walks.

More than 15 rangers took part in the monitoring and filming activities, including Karajarri, Marranbala, Girringun and Mabuyagiw Rangers, with support from Karajarri Traditional Lands Association, Namultja Aboriginal Corporation, Girringun Aboriginal Corporation and the Torres Strait Regional Authority Land and Sea Management Unit, filmmakers Gus Burrows (Styledia) and Sam Frederick, and researchers from James Cook University, Charles Darwin University and Edith Cowan University. The footage captured during these activities will form part of a new suite of accessible training resources to support ranger-led seagrass monitoring across northern Australia.

“The resources will give ranger groups clear, practical steps for monitoring seagrass in different environments. It is designed so each group can select the best methods for their Sea Country while collecting data that contributes to a broader national picture,” said Dr Alex Carter, a project leader from James Cook University’s TropWATER.

Seagrass meadows are among the most productive ecosystems on Earth. They provide food and habitat for threatened species such as dugongs and green turtles, protect coastlines from erosion, and store significant amounts of carbon. Yet these habitats are under growing pressure from climate change, cyclones, flooding and human activity. Many areas across northern Australia remain poorly studied, and consistent monitoring data are limited.

“The monitoring was very interesting to the Rangers because we learnt about the different seagrass that we have on our country and that we can use data in the future if we wanted to do mapping or find out about the dugong habitat and feeding grounds. That is also important to us.

The crew also had to do the run down on setting up and packing the equipment that were used, that was very handy for future if wanted to go out and do it on our own we now have the skills and knowledge,” said Kelvin Mitchelson, from the Karajarri Rangers.

This Hub project addresses this gap by co-developing a practical toolkit for rangers to survey, map, and assess seagrass health using a consistent monitoring framework tailored to local conditions. The project’s co-design process ensures the tools, training materials, and monitoring protocols reflect local priorities, Indigenous knowledge and the diversity of northern coastal environments. The project is also building technical capacity within ranger groups through hands-on training and the creation of multimedia resources that demonstrate best-practice survey methods.

“Our goal is to make seagrass monitoring accessible and consistent across the north, giving ranger groups the confidence and tools to independently lead long-term monitoring of seagrass.”

By enabling rangers to collect high-quality data on seagrass distribution and condition, the project will help inform local decision-making and national reporting frameworks for the health of coastal ecosystems.

“You take away our seagrass, you take away our culture”.

Through collaborative efforts like this and related projects, such as Project 3.5 and Project 4.1, the Hub is helping establish enduring Indigenous-led seagrass monitoring programs, ensuring that stewardship of these vital ecosystems remains with those most connected to Sea Country.
