The introduction of exotic diseases, especially, continues to be a threat to forest trees and, hence, the forest. [22] Humans have also introduced earthworms in deciduous forests in Norh America, which has had a deep impact on the ecosystem and reduced biodiversity.
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 ...
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.

Temperate deciduous forests dominated from about 33° to 30° N. latitude, including most of the glacial Gulf Coast from about 84° W. longitude. The coastline later changed during glacial melt, both in the Mississippi River valley and sea level rise of 130 meters (430 ft).
The Eastern Great Lakes lowland forests are very rich in wildlife. Birds include cardinals, downy woodpecker, wood duck and eastern screech owl.Large mammals including Canada lynx (Lynx canadensis), cougar (Puma concolor), caribou (Rangifer tarandus), wolverine (Gulo gulo), elk (Cervus canadensis) and eastern wolf (Canis lycaon) have been completely extirpated from this ecoregion; remaining ...
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.
The New England-Acadian forests are a temperate broadleaf and mixed forest ecoregion in North America that includes a variety of habitats on the hills, mountains and plateaus of New England and New York State in the Northeastern United States, and Quebec and the Maritime Provinces of Eastern Canada.
Areas of the globe with a temperate broadleaf and mixed forest biome, according to the WWF. A temperate forest is a forest found between the tropical and boreal regions, located in the temperate zone. It is the second largest terrestrial biome, covering 25% [1] of the world's forest area, only behind the boreal forest, which covers
