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 ...
The Boreal Mountains and Plateaus Ecoregion is unique among other British Columbia ecoregions in that it contains several volcanoes of late Tertiary and Pleistocene age. Level Mountain and Mount Edziza are the most prominent volcanoes of this ecoregion which reach elevations of 2,134 m (7,001 ft) and 2,787 m (9,144 ft), respectively.
The boreal forest/taiga supports a relatively small variety of highly specialized and adapted animals, due to the harshness of the climate. Canada's boreal forest includes 85 species of mammals, 130 species of fish, and an estimated 32,000 species of insects. [37] Insects play a critical role as pollinators, decomposers, and as a part of the ...
Fire is the dominant type of disturbance in boreal North America, but the past 30-plus years have seen a gradual increase in fire frequency and severity as a result of warmer and drier conditions. From the 1960s to the 1990s, the annual area burned increased from an average of 1.4 to 3.1 million hectares per year.
Terrestrial ecoregions of the world. This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial, freshwater, and marine ecoregions.
The Canadian boreal region contains the largest area of wetlands of any ecosystem of the world, serving as breeding ground for over 12 million waterbirds and millions of land birds, the latter including species as diverse as vultures, hawks, grouse, owls, hummingbirds, kingfishers, woodpeckers, and passerines (or perching birds, often referred ...
Appalachian bogs are boreal ecosystems, which occur in many places in the Appalachians, particularly the Allegheny and Blue Ridge subranges. [19] Though popularly called bogs, many of them are technically fens. [20] Bog species include cranberry and blueberry (Vaccinium spp.), bog rosemary (Andromeda glaucophylla), and buckbean (Menyanthes ...
The boreal forests in the interior of the continents grow on top of permafrost due to very cold winters (see drunken trees), though much of the boreal forest biome has patchy permafrost or lacks permafrost completely. The short (3–4 month) growing season in boreal forests is sustained by greater levels of rainfall than the tundra receives ...
