Slide 45 : Conclusions
A number of conclusions can be drawn from this work. Firstly, climate and carbon dioxide have definitely changed in the past, and sometimes very rapidly. However, in the past 2 million years this change has been strictly bounded. We can conclude that species tend to migrate in response to climate change (although adaptation is another response, it is not likely to be relevant over a period of climate change as rapid as the current anthropogenic effects). Furthermore, CO2, fire and other disturbances affect the distribution of plants, and so management responses are vital to survival of species. Most importantly, although biological response models are very useful tools in managing and determining plant response, their outputs must be viewed with some degree of skepticism, taking into account their assumptions and uncertainties.
