Parkinson drew 141 plant species, but by 28 July, Banks had had enough. In agriculture, useful foreign plants such as wheat or barley dont seem to naturalise and need to be re-sown each year, while others grow out of control and overrun grazing and crop fields, costing the sector about $3.5 billion a year, excluding the environmental cost of increased chemical weeding.
