Fire-stick farming had the long-term effect of turning scrub into grassland, increasing the population of nonspecific grass eating species like the kangaroo. The ecological disturbance caused by fire-stick farming has been implicated in the extinction of the Australian megafauna.
In wet and dry sclerophyll forests, firestick farming opened the canopy and allowed germination of understory plants necessary for increasing the carrying capacity of the local environment for browsing marsupials.
