Changes in the forest ecosystem are primarily a result of changes in forest structure and species composition. [1] American chestnut used to compose up to 50 percent of the canopy in many eastern deciduous forest, [11] Ash species make up 7 percent of all Wisconsin forests (for example) [12] and up to 90 percent of some forests.

Forests in the United States can be categorized into three main forest biomes, they are boreal, temperate, or sub-tropical based on the location and climate of the forest. Each of these biomes faces various threats of deforestation , urban development, [ 2 ] soil compaction , species extinction, unmanaged recreational use, invasive species , or ...
Temperate deciduous or temperate broad-leaf forests are a variety of temperate forest 'dominated' by deciduous trees that lose their leaves each winter. [1] They represent one of Earth's major biomes , making up 9.69% of global land area. [ 2 ]
For a general description of these forests, refer to Temperate Deciduous Forest. The standard reference is The Deciduous Forest of Eastern North America. [4] The adjoining forests in Canada are generally referred to as the Mixedwood Plains Ecozone or the Great Lakes-St.Lawrence Forest Region. 32 Texas Blackland Prairies; 33 East Central Texas ...

Sugar maple-paper birch forest in Hiawatha National Forest, Michigan. This ecoregion is a transition area between the taiga (Boreal forest) to the north and the temperate deciduous forest and tallgrass prairie to the south and west and thus contains a variety of habitats including northern coniferous forests, northern hardwood forest, boreal hardwood-conifer forest, swamp forest, and peatland ...
The biggest threat besides climate change to the eastern temperate forest is its high density of human inhabitants. According to the Commission for Environmental Cooperation approximately 160 million people or over 40 percent of North America’s population, lives within the ecological region of the eastern temperate forest12.
9.2% [1] 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.
