Slide 33: CO2 crisis for C3, woody plants
One aspect we have been particularly interested to test is the action of CO2 on woody plants. Trees require much more CO2 than grasses to maintain their woody structure. By analysing past changes in vegetation structure, it becomes clear that when CO2 rises, woody plants become more successful, and under low C02 grasses become more successful. This was then tested using modelling and experiments.
