Managing late dry-season wildfire in West Arnhem Land: a model plateau where early cool burns at the scale of one estate or the whole plateau change how much land hot late fires reach
The best fire plan here starts with more fire
In the tropical savanna of West Arnhem Land, the big challenge is hot wildfire late in the dry season, with impacts on the land, its people and the economy. Aboriginal ranger groups manage it with small, cool burns early in the year, and whether that response works depends on the scale they burn at. Add early burns, then switch between one estate and the whole plateau and watch how much country the late fires reach.

Know This
A management response is judged by whether it shrank the challenge, and early burning only cuts late dry-season fire when it works at the same scale the fire travels: the whole landscape.
