Transcript of Taiga Biome
In the Taiga, there are many different animals that live in the biome. Some of them are, American Black Bear, Bald Eagle, Bobcat, Canadian Lynx, Gray Wolf, Grizzly Bear, Long-Eared Owl, Red Fox, River Otter, Snowshoe Rabbit, Ermine, Wolverine, Woodland Caribou, Elk, Mule Deer, Moose, beaver, Red Squirrel and Reindeer.
Threats facing this biome (Due to human activities)
Taiga Biome by Harry B
In the Taiga, as to the cold, extreme weather; and poor, acidic soil, there aren't many types of plants present, and a lot of the plants are evergreen trees to help survive better in the cold winter. There are plants such as, the Balsam Fir tree, Black Spruce, Douglas Fir, Eastern Red Cedar, Jack Pine, Paper Birch, Siberian Spruce, White Fir, White Popular, and White Spruce.
Threats facing this biome (Due to human activities)
Precipitation and Temperature
In the winter, the temperature can fall up to -60 degrees Celsius, and doesn’t go above 3 degrees Celsius. In the summer, the temperature can fall up to -7 degrees Celsius, and doesn’t go above 40 degrees Celsius.
The Black Spruce is a tall coniferous tree, able to grow to 25 meters tall. It's able to survive in the cold weather in the Taiga because of the following adaptions.
Status of the biome
In the Taiga the temperature is mainly low. There are usually 6-7 months of winter and the tilt of the Earth causes winters to be in almost darkness. Winters are very cold and snowy in the Taiga. The summers in the Taiga are usually about 50-100 warm days and can last up to 20 hours of daylight. The summers in Taiga are warm, humid, and rainy. The autumn in Taiga is extremely short, and the spring melts snow, ponds and brings flowers, which wakes up animals from hibernation.

In taiga the precipitation comes in 2 different forms. In winter the average amount of snowfall annually is about 20-40(50.8-101.6cm) inches. In summer the average amount of rainfall annually is about 10-20 inches (25.4-50.8cm).
Black Spruce (Picea mariana)
adaption to Taiga
-Layered twigs to protect it from breaking.
-Waxy pine needles to survive the cold.
-Rough bark to protect itself from animals.
-Enjoys cold climate and poor soil.
(Betula papyrifera) adaptions to Taiga
The Paper Birch is a medium sized deciduous tree able to grow 60-80 inches high. It's called the "Paper Birch" because it can peel of in many layers. It's able to survive in the environment with extreme weather because of its following adaptions
-Branches and twigs are flexible, unlikely break under loads of snow.
-Lose eaves in the winter, reducing water loss.
-Bark contains resinous oils that make it durable.
-The trunk is strong, hard to break in winter.
There are structural or behavioral adaptions that animals have or do to survive better in the Taiga. Some of them are:
Thick fur - Allows animals to keep warm during the cold winter.
Changing colors - Allows animals like Ermine or snowshoe hare to blend in with the snowy environment.
- Some species of birds stay in the Taiga at spring and summer, and leaves to South before winter starts. This allows birds to benefit from Taiga's wetlands abundant with insects and plants at summer, without risks from the cold winter.
Large feet - Some animals like Snowshoe hare have large feet, allowing them to move better in snow.
Hibernation - Some animals like bears, squirrels, badgers, chipmunks, or frogs go hibernate in winter.
Map of Taiga
Taiga meaning forest in Russian is the the largest biome in the world. Taiga covers large potions of Canada, Asia ,and Russia. Taiga is the biome consisting mostly evergreen forests. Coldness and food shortages make things difficult, mostly in the winter.
Huge number of trees are cut down to meet the need of paper, and lumber products. It makes the trees release carbon dioxide that was stored inside.
The source of this threat are the people that cut down trees to make money, and the people that overuses products made from trees.
In Canada 8% of taiga is protected by the provincial government. Reforestation—which is the process of replanting trees, can help restore trees in taiga.
Global Warming: Global warming is an effect that increase temperature, caused by greenhouse gases (created mostly from human activities) in the air.
The increase in temperature in taiga can cause more chance of wild fires, and bark beetle infestations.
Acid Rain: it's created when air pollution from power plants and factories that burn fossil fuels stay in the atmosphere, rain back to the ground. Acid rain will weaken the trees by poisoning the trees with toxic substances and limit the nutrition needed to survive.
The Kyoto Protocol was developed to lessen future global warming, and reduce emissions from factories by substantially reducing Developed Countries’ greenhouse gas and carbon emissions.
Gray wolves can survive in any environments, long as food is plentiful and the climate is cold. Gray wolves travel in packs of 4-30 members, lead by an Alpha male and female wolf. They are around 3 feet tall and are about 3 to 5 feet in length from nose to tail. Their weight ranges from 40 to 176 pounds and eats animals such as, caribou, moose, and deer. The maximum lifespan of a Gray Wolf is 17 years.
The River Otter usually inhabit areas that have thick woods, lakes, swamps, rocks, and logs near grassy areas, streams, and rivers. It's 25-30 inches long to body to head and its tail is 16-18 inches long. It's weight is about 25 pounds, and their main food is fish.
Woodland Caribou are the largest of all caribou subspecies in Canada. Male caribou are average 150 kilograms and approximately 1.2 meters tall. The antlers are thicker, wider and more compact in comparison with the other subspecies. The average lifespan is 4.5 years with a maximum of 15 years.
The taiga biome is doing okay for now but in 50-100 years, it might get worse, because of all the human threats to the environment.
