Climate change and forests
Because we are in the center of the continent, we can expect a higher magnitude of warming than many other regions, and because we are close to the prairie-forest border, in an environment that is not optimal for forest to begin with, we can expect the impacts on forests to be large. In addition, the effects of a warmer climate on forests will be reinforced by more storms, droughts, fires, insects pests and diseases, high deer populations, and invasive species. Savannification of large areas of forest on shallow or sandy soils and replacement of the boreal forest by temperate forest and savanna is likely to occur by the end of the century.
