What land management practice did Aboriginal Australians use?

Aboriginal Australians used sophisticated land management practices for tens of thousands of years, including controlled burning, fish trap construction, soakage management, and seasonal harvesting patterns that shaped the Australian landscape long before European arrival. Their practices are increasingly recognised by modern scientists and conservation agencies as sophisticated ecological management.

Fire management is the most studied Aboriginal practice. Aboriginal people across the continent used controlled, low-intensity fires at specific seasons (often called cool burning or cultural burning) to reduce fuel loads, encourage particular food plants, drive game during hunting, and refresh country. The mosaic of regularly burnt patches created varied habitats that supported wildlife. European arrival largely ended Aboriginal fire management, contributing to the buildup of fuel loads that has driven the increased intensity of modern Australian bushfires.

Other practices were equally sophisticated. The Brewarrina fish traps in north-west New South Wales, estimated at more than 40,000 years old, are among the oldest human-built structures in the world. The Budj Bim aquaculture system in south-west Victoria, built by the Gunditjmara people about 6,600 years ago, captured and stored live eels in stone channels and ponds and is now UNESCO World Heritage listed (2019). Across the continent, Aboriginal peoples managed grain harvests, planted yam patches, constructed eel weirs, and developed sophisticated knowledge of seasonal patterns and ecological connections.

Modern conservation increasingly draws on Aboriginal knowledge. The Indigenous Protected Area programme, established in 1997, supports Aboriginal communities to declare and manage their own conservation reserves on country. More than 80 Indigenous Protected Areas cover about 87 million hectares (more than half of the National Reserve System). The Indigenous Rangers programme, established in 2007, employs more than 1,900 Aboriginal and Torres Strait Islander people in cultural land management roles. After the 2019 to 2020 Black Summer fires, fire agencies and state governments accelerated programmes to partner with Aboriginal rangers to reintroduce cool-burn techniques across public lands. The federal Indigenous Carbon Industry Network supports traditional owners to earn carbon credits through fire-management projects.
