A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. [1] The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal ...
First, "Boreal" can identify a paleoclimate, a pollen zone or a temporally-fixed chronozone, and those three bases of definition allow quite different dates. Second, different dating methods obtain different dates. The underlying problem is that climate and pollen vary somewhat from region to region.
The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates .

The Boreal forest and its alpine cousins are host to a wide variety of deer, ranging from the large moose to the whitetail deer. All of these large herbivores prefer the cool forest lest they overheat in the sun, but all need open land on which to graze. Of the deer, moose are perhaps best adapted to wetlands and thrive in the boggy boreal forest.
Extent of temperate broadleaf and mixed forests An example of temperate broadleaf and mixed forest in La Mauricie National Park, Quebec.. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.
The Boreal kingdom or Holarctic kingdom (Holarctis) is a floristic kingdom identified (1947) by botanist Ronald Good [1] (and later by Armen Takhtajan), which includes the temperate to Arctic portions of North America and Eurasia.
