Although there are rather few species of trees in the boreal forest, there is a considerable diversity of other kinds of plants. An accurate summary is difficult, since most compendia on plants are organized by political, rather than ecological boundaries; one exception addresses the flora of the Hudson Bay Lowland , [ 28 ] but much of this ...
Boreal ecosystems are some of the most vulnerable to climate change. Both loss of permafrost, reductions in cold weather and increases in summer heat cause significant changes to ecosystems, displacing cold-adapted species, increasing forest fires, and making ecosystems vulnerable to changing to other ecosystem types.
The dominant trees of these coastal forests are balsam fir Abies balsamea along with black spruce Picea mariana, white spruce Picea glauca on the shoreline, and paper birch Betula papyrifera and aspen Populus tremuloides where the forest is regrown following logging or other disturbance. Other plants include mosses and coastal heath shrubs.
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 ...
Because the island is young and isolated from larger land masses, species biodiversity is relatively low. Forest cover has been reduced to about 1% of the original birch forest by a long history of timber extraction and soil erosion caused by sheep grazing. Blanket bogs (areas of high rainfall and peat accumulation) are common. [1] [2] [3] [4]
Where the rock is covered in soils, the forest takes on the characteristics and species of the Southern Boreal Forest ecozone. [13] The plant hardiness zone would be Zone 0b. [18] The Athabasca Basin provides a separate ecosystem. The Athabasca Sand Hills protected by The Athabasca Sand Dunes Provincial Park are unique feature of the Canadian ...
Southern spruce–fir stands consist primarily of two needle-leaved evergreen species—the red spruce and the Fraser fir, nicknamed the "he-balsam" and "she-balsam," respectively. Regional entities sometimes refer to the southern spruce–fir forest as the "Canadian" or "boreal" forest because of its resemblance to the boreal forest of Canada ...
Clintonia borealis is a species of flowering plant in the lily family Liliaceae. The specific epithet borealis means "of the north," which alludes to the fact that the species tends to thrive in the boreal forests of eastern Canada and northeastern United States. [3] Clintonia borealis is commonly known as bluebead, bluebead lily, or yellow ...
