Indigenous knowledge helps reveal the ties between reefs and mangroves

In a recent scientific article in the journal Ocean & Coastal Management, alongside the list of scientist-authors were the Bardi Jawi and Oorany Rangers and the Bardi Jawi Traditional Owners. For the past decade, Bardi Jawi rangers and traditional owners have been working with the Australian Institute of Marine Science (AIMS) to study and protect their mangrove and reef ecosystems, as well as their traditional Indigenous fishing grounds. The Bardi Jawi, according to Phillip “Bibido” McCarthy, are a “Saltwater People” whose traditional diet revolves around healthy oceans. Their land, located in the Kimberley region of northwestern Australia, is of “red earth, blue ocean, and green mangroves,” Bibido, the 59-year-old coordinator of the Bardi Jawi men’s ranger program, tells Mongabay. Bardi Jawi Country forms part of the 95,000-hectare (235,000-acre) Bardi Jawi Indigenous Protected Area (declared in 2013 and administered by the Bardi Jawi) and the 204,000-hectare (504,000-acre) Bardi Jawi Gaarra Marine Park (established in 2022, with a zoning scheme that came into force in July 2026). Among the most important findings in the study was the interconnectedness between reef and mangrove ecosystems for sustaining fisheries — an aspect long recognized in Bardi Jawi traditional ecological knowledge. The overall project and its findings also guided the design of both the IPA and marine park. Cape Leveque on the Dampier Peninsula in Western Australia. Image by Marty Southwell via Unsplash.
