As I read the article saying that global warming will cause weeds to take over the world, I thought of the fact that in Christchurch, this has already happened.
"As habitats change in response to climate change, the species that are most likely to survive are those with short life cycles that can adapt quickly and those that are readily dispersed, common characteristics of most weed species," the trust's senior botanist Peter Weston said.
Long ago the council gave up trying to plant anything exotic. Now we just get flax, dodgy species of grass and other assorted swamp plants. I was rather hoping that global warming would kill these off and we could have our colourful city back, but apparently not.
"We were struck by the conservatism of plants, basically how rarely they were able to adapt and flourish outside of their ancestral environments," Dr Weston said in a statement.
Dr Weston needs to get out more. Most of the decent trees in Christchurch are introduced.
