The Eastern Temperate Forest Ecoregion has favorable growing conditions for a number of plant species, the dominant being large, broadleaf, deciduous trees. [2] Before the arrival of Europeans, this area was almost completely forested.
The Carolinian forest refers to a life zone in eastern North America characterized primarily by the predominance of deciduous (broad-leaf) forest. [1] The term "Carolinian", which is most commonly used in Canada, refers to the deciduous forests which span across much of the eastern United States from North Carolina northward into southern Ontario, Canada.
In these forests, winter is a time of dormancy for plants, [8] when broadleaf deciduous trees conserve energy and prevent water loss, and many animal species hibernate or migrate. [1] Preceding winter is fruit-bearing autumn, a time when leaves change color to various shades of red, yellow, and orange as chlorophyll breakdown gives rise to ...
These covered 36% of the region's land and 52% of the upland areas. Of this, less than 1% of the unaltered forest still stands. [9] In the Eastern Deciduous Forest, frequent fires kept open areas that supported herds of bison. Agricultural Native Americans extensively burned a substantial portion of this forest.
Lysimachia borealis is found from Canada to north-central and eastern United States, primarily in boreal forest in Canada and in northern conifer-hardwood forests in the United States. [8] It is found in temperate climates. [12] The species is one of the ten most common herbaceous-layer native plants in eastern deciduous U.S. National Park forests.
The appearance of invasive pathogens of the American Chestnut into the eastern deciduous forest ecosystem is just one instance of the Columbian exchange of pathogens. While the Columbian exchange moved valuable crops between the Americas, Europe and Asia, there was also a downside, as the rapid introduction of invasive and unfamiliar pathogens ...
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.
Forests and woodlands are the most widespread plant communities, interspersed with steppe and shrublands. Forests typically have an open canopy and a grassy understory. The predominant trees are deciduous oaks, including Quercus brantii, Q. libani, Q. boissieri, and Q. ithaburensis ssp. macrolepis.
