Final answer:
Cultural burning in Australia ended largely because British settlers banned the practice upon their arrival, leading to ecological imbalances and adverse effects on wildlife.
Step-by-step explanation:
According to historical evidence, cultural burning ended in many parts of Australia because the British settlers arrived and banned the practice. This ban led to a cessation of Aboriginal landscape burning which had once maintained a fine-grained mosaic of burnt patches of varying ages, preventing large-scale disastrous fires by reducing flammable grass biomass. After European colonization, altered fire regimes resulted in large, intense, and infrequent fires, adversely affecting mammal populations and disrupting the ecological balance maintained by Aboriginal people for millennia.
