Plants are multicellular eukaryotic organisms with the ability to produce their own food by the process of photosynthesis. The rainforests in India and Australia have 47 genera in common. Pest animals and weeds damage agriculture and harm our environment. These include birds, plants, insects and invertebrates. "This is a pool from which some plants will grow to become weeds," says Dr Richard Groves, researcher at CSIRO Plant Industry, who recently gave a public lecture at at the . 1926: Introduction of Cactoblastis cactorum moth leads to the eradication of prickly pear infestation across Australia. However, cane toads rapidly grew into pests, growing beyond human control and spreading throughout Queensland and other Australian states. Unlike native plants, introduced weeds have no natural predators or diseases in their new environment. How were these different to the old ways of fire-stick farming and native foods? A prickly invasion, National Museum of Australia, Eradication of prickly pear in Australia, Nature. (2015) The biggest estate on earth ABC News. However, plans for the testing and release of these biological agents were put on hold after the First World War broke out in August 1914.

Prior to colonisation, Aboriginal and Torres Strait Islander peoples used fire-stick farming to manage the landscape for sustainable food production, but the events of colonisation resulted in profound changes in the landscape. From 1840 to 1907, somewhere between 10,000 to 20,000 camels were transported to the continent from India. During the voyage, Banks and his team made the first scientific collections of Australian flora.

Its ability to thrive in so many different native habitats makes this species a concerning invasive plant, as it reduces the availability of sunlight and resources for other native species to flourish. Algae have historically been included with the plants, but they are now classified with the protists. These camels cause environment damage to vegetation because of their foraging activity, trampling, and consumption of rare and endangered flora. This specimen was collected by Banks and Solander on the first of Cook's Pacific voyages.
