The Big Picture
The Big Picture
This chapter maps the geographic extent of the ecosystems created by conifers, and coincidentally the areas of dominance of one or more identifying conifer species. The result is a mosaic of “regions.” In all the regions except the Great Lakes, the St. Lawrence, and the Acadian, conifers dominate. The forests of the latter two regions vary between coniferous and mixed (that is, with various broadleafs as well as conifers). The trees that are found at any one site depend mainly on the climate, the terrain and soil, the location from which their ancestors immigrated, and the number of years since the site was last burned. In mountainous country, elevation is another important factor.
