Aboriginal people4 closely managed the land and were not simply hunter gatherers; they used detailed burning plans in what is called fire-stick farming5. Horticulture is by far the main source of plant introduction. This specimen was collected by Banks and Solander on the first of Cook's Pacific voyages.

Using historical and genetic data, scientists have pinpointed the. As a result, fire management was effectively stopped allowing fuel loads to build up, over time leading to bigger more intense fires. Dingoes can interbreed with feral dogs and produce hybrids. There is now very little native grassland, an overabundance of exotic pasture grass overrun by hard hooved animals, and there is more dense forest, and forest with thick understorey, providing fuel for bigger hotter fires that are dangerous and destructive. And despite their name, black rats can have grey, black, cream white or light brown fur. Introduced species now outnumber Australian plants, say botanists.
