Plants "on death row"
"We were struck by the conservatism of plants - how rarely they were able to adapt and flourish outside of their ancestral environments," said Dr Weston, of the Botanic Gardens Trust.
This made it likely that many species would have trouble surviving if their current habitats shrank as a result of climate change, he said. [Climate is always changing ... if you can't adapt, you won't survive - that's evolution - Ed]
Those least likely to go extinct were plants with short life cycles and that spread easily - both characteristics of weeds.
"Weeds will be the beneficiaries of climate change," Dr Weston said.
