(Distribution of Boreal forest in North America represented by dark blue, The Boreal Forest mostly located in Canada and Alaska.)
Ecology Overview: The Canadian boreal forest came to be at the end of the last ice age. White spruce, black spruce and tamarack are the most popular in the four northern part of the Taiga and Hudson Plains, while spruce, balsam fir, jack pine, white birch and trembling Aspen are most common in the lower boreal regions. A lot of trembling aspen and willow trees are found in the southernmost parts of the Boreal Plains.
Dangers: The Boreal Forest has many dramatic disturbances or problems including wind, fire, ice storms, pathogen and pest infestation. One dominant characteristic of the boreal is that much of it consists of large, even-aged stands, a unchanging cycle of natural disturbances like forest fires, or outbreaks of pine beetle or spruce budworm that kill large tracts of forest with cyclical regularity.
Climate: The average boreal forest climate is dominated by cold arctic air. The average temperature is slightly over 50 F degrees. The temperature range is -65 degrees F to 70 degrees F.
Winter's LOWEST temperature in taiga is -65°F.
Winter's HIGHEST temperature is 30° F.
Summer's LOWEST temperature is 30° F.
Summer's HIGHEST temperature is 70° F.The temperature range, as you can see, is -65° F to 70°F (-54 to 21° C). For half of the year, the average temperature is below freezing. In the winter the average air temperature is warmer than it is for tundra, which lies north of the taiga. The taiga climate has an average annual rainfall of 12 - 33 inches (30 - 84 cm). Most of it falls in the summer as rain.
Background Information: The boreal forest is the second largest biome in the world containing 33% of the Earth's forest cover, which approximately 25% is natural. It is circumpolar and shares similar taxa across its range. It has approximately 20, 300 identified species. Along with the tropics, the boreal forest is both a major depository and at times a major source of carbon. However, unlike most ecosystems in the world, the boreal forest is still sparsely populated by humans and therefore largely intact. It is one of the few biomes in which large predator–prey systems are still widely operational, invasive species are few by proportion, and large-scale natural disturbances such as wildfire and epidemic insects still occur extensively at their natural frequencies and patterns.
Extra Info: Taiga is the world's largest terrestrial biome. In North America it covers most of inland Canada and Alaska as well as parts of the extreme northern United States and is known as the Northwoods.
Biotic and Abiotic Factors: There are many biotic factors and abiotic factors in the boreal forest. Some abiotic factors are large amounts of precipertation, hot and cold seasons, little amount of sunlight through the tall trees, fertile soil, and the distance from the sea.
Some biotic factors are the Black Bear, the Fox, the Squirrel, the Deer, the Coyote, the Bald Eagle, the Balsam Fir and the Jack Pine. Taiga is overflowing with species of animals and plants, just waiting for visitors to see!
