Watch documentary First Footsteps (Episode 4) and/or First Australians (Episode 1): Consider the effects of colonisation on Aboriginal and Torres Strait Islander people with regards to fire management. 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. If it is not dealt with, it can quickly form dense stands on creek and river banks, suppressing the opportunity for native vegetation to grow in the process. Introduced plants outnumber natives - Australian Geographic 1926: Introduction of Cactoblastis cactorum moth leads to the eradication of prickly pear infestation across Australia.

Black rats likely hitched a ride with the First Fleet, making them one of the first introduced species in Australia. Soil compaction, the change in soil salinity and waterway pollution caused by agricultural practices introduced to the country has lead to the further evolution of the flora of Australia. Though the Australian Quarantine and Inspection Service implement effective invasive species management at our national borders, says Richard, plants can be easily transferred across states, where they can establish themselves and wreak havoc.

Four of Australias native plants have already been wiped out by weeds choking them, and another 57 are under threat of same fate. Instead a number of varieties of the prickly pear were introduced to Australian gardens in the mid-1800s. The evolution of Australias flora begins with the continental drift that divided all the continents of the world into separate land masses.
