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
The Southern Great Lakes lowland forests is a temperate broadleaf and mixed forest ecoregion of North America, as defined by the World Wildlife Fund. Located near the Great Lakes, it lies mostly in the central northeastern United States and extends into southeast central Canada. In modern times, little of it remains intact due to land use ...
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 ...
