This time of intense disturbance to the Aboriginal way of life led to a drastic decline in both the traditional knowledge of land management and the ability of Aboriginal peoples to carry out their land management practices.

A dye industry Introduced weeds reduce the diversity and/or abundance of native species or adversely affect the function of natural ecosystems. Introduced in the 1800s by European settlers, their population multiplied due to the lack of predators in their new environment. Some exotic species that have been imported to decorate houses and gardens have found there way into the countryside and have depleted the soil and choked out native species. If spring has been wet, the abundant plant growth only provides more fuel for late-summer fires. Australia also shares 41 genera with Papua New Guinea. The classifications have been changed and there are now two categories: The flora of the continent evolved from the relictual forests. Most of them were released in Melbourne, though established populations now exist all over the continent. After leaving Botany Bay, they spent seven or so days collecting specimens at other landings along the coast. When it was reduced in 1950, the virus was able to kill over 90 percent of feral rabbits. While weather conditions and natural phenomena have had a great impact on how flora has evolved on the Australian continent, the impact of man has also greatly influenced the evolution of flora as evidenced by the evolution of plant species in Australia. Many scientists have spent years exploring ways to eradicate cane toads. Make miniature mechanised minions with teeny tiny tools!

But why do they consider these biological control programs a priority? It was founded in 1836. . Many of the introduced species of flora have proved themselves to be invasive and have done their part to wipe out native species by overcrowding their habitat. It can take some time before introduced species of plants are identified as invasive or as weeds.
