Fire is undoubtedly one of the most important factors influencing the health of the country, economic viability, and the cultural values of Cape York.
Indigenous people have supported biodiversity with knowledge-based fires for thousands of years, but wild fires can be very damaging.
Wild fires mean that ecosystems are injured and may be significantly changed, graziers lose pasture and stock, and erosion and sediment run-off can badly affect even the Great Barrier Reef. People managing their property as part of a fire carbon farming project also suffer significant economic loss.
Recently there has been a resurgence in traditional burning practices on Cape York.

Arnhem Land – Aboriginal fire ecologist, Dean Yibarbuk, explains how traditional fire management practices have kept the country healthy for thousands of years.

Mr Bangmorra role is to use his expertise in preventing exactly the types of savanna bushfires that emit an estimated two gigatonnes of carbon worldwide each year. His is a risky and difficult craft, he carries out cool-weather burns in a mosaic pattern that stop summer bushfires in their tracks and this makes him very valuable in what is increasingly called the carbon economy.
