The Eastern Temperate Forests is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. The region covers much of the Eastern and Midwestern United States, the U.S. Interior Highlands, and parts of Ontario, Quebec, and the Maritimes.
The boreal forests of the early Quaternary enjoyed a modest expansion. Riparian, bottomland, and wetland plant communities expanded. The grassy woodlands contracted and retracted westward. [6] Prescribed fire in Virginia, 1995. Many eastern ridgetops were burned by American Indians.
The eastern forest–boreal transition is a temperate broadleaf and mixed forests ecoregion of North America, mostly in eastern Canada. It is a transitional zone or region between the predominantly coniferous Boreal Forest and the mostly deciduous broadleaf forest region further south.

The area is a temperate broadleaf and mixed forests biome transition zone between the true boreal forest to the north and the Big Woods and Carolinian forest to the south, with characteristics of each. It has areas of both broadleaf and conifer forest cover, and bodies of water ranging from lakes to conifer bogs and swamps. [2]
Alaska is the most biodiverse state with 15 ecoregions across three biomes in the same realm. California comes in a close second with 13 ecoregions across four biomes in the same realm. By contrast, Rhode Island is the least biodiverse with just one ecoregion—the Northeastern coastal forests —encompassing the entire state.
The Appalachian–Blue Ridge forests are an ecoregion in the Temperate broadleaf and mixed forests Biome, in the Eastern United States. The ecoregion is located in the central and southern Appalachian Mountains , including the Ridge-and-Valley Appalachians and the Blue Ridge Mountains .
At lower elevations to the east are the Middle Atlantic coastal forests on the Atlantic coastal plain. Similarly, the Southeastern conifer forests occupy the Gulf coastal plain to the south. Higher, and to the north and west, are the Appalachian-Blue Ridge forests and the Appalachian mixed mesophytic forests of the Appalachian Mountains. [2]
