Breakthrough in the battle against invasive plants . New research by one of our ecologists, Dr Kim Jelbert (lead author) and a team of scientists across Europe.
“What we found was a real surprise’ says Professor Dave Hodgson (senior author). Invasive plant populations grow fast in their invaded range, but not in their native range. So you can’t use population growth to predict invasiveness. However, invasive plant species have an amazing ability to ‘bounce back’ from disturbances, and we can see this in both their native range and their invaded range”.
Dr Kim Jelbert, lead author of the paper, said: “The kinds of species that bounce back from disturbance tend to be species that produce lots of seeds from large flowers. This is a real problem, because large flowers are popular with gardeners all over the world. These species should not be traded internationally”.
“We also discovered patterns of ancestry. Close relatives of invasive plants are also likely to be invasive if they escape their native range.”
