It grows to be 40 to 80 feet tall. The Balsam fir has a wide base and a narrow top that ends like a point. The branches grow from the truck at 90° angles.On the branches, it has needles. The needles are 1 1/2 inches long. They are flat, rounded at the tip, and normally have a strong curve in the middle. They can be up to 200 years old. These trees are sometimes used as lumber. The wood is low in bending, and low in resistance to shock, too! The tree can also be used as a Christmas tree, or wood to make cabin logs. The Black Spruce is a tall tree that has blue-green needles and small, egg-shaped cones on it. The sharp needles have four side on them, and are short and pointed. The bark located on the tree is gray-brown. The branches droop, and are usually layered. They are short. The wood is used to build houses. The wood is layered, so it is thick and has many coatings of bark. The tree can also be used for ropes, antiscorbutic beverages, and sometimes Christmas trees. Douglas-firs are very big. They can grow from 40 to 60 feet tall and 15 to 25 feet wide. Since they are very big in size, they are a great wood for lumbers, timbers, and plywood. The wood is very hard, durable, and stiff. The trunk is used for lumber and the leaves can be steeped for tea. The Eastern Red Cedar grows in a pyramid shape. The top rounds off as it increases in age. It has two types of leaves; older and younger, The older ones are flat and scale-like and only 1/16 of an inch. The younger leaves are sharp, pointed, and can be up to ¾ of an inch. On the top, they have whitish lines. In the winter, they can turn yellow to brown, and in the summer they are vibrant green. The tree provides fruit for animals such as pheasants, Cedar wax-wings, and other song birds. The birds eat the seeds, then spread them. The wood is used to make wooden pencils and fence posts. The Jack pine can grown to be twenty-seven meters tall and about sixteen to thirty-two centimeters in diameter around the trunk. As the tree grows, the crown area gets rounder and rounder. The flat bark of the Jack pine is a brownish-red. Instead of leaves, it has needles. This tree is good for the environment because it gives most animals their nutrients. The tree gives it mostly to rodents in the area. The jack pine has two major uses. The jack pine is used to build houses and it is used to make pulp for paper. Paper birch trees have a thin bark that peels in horizontal layers. The layers then separate into sheets, almost like paper. They can grow in pairs or cluster of twenty to forty trees. There are several different type of paper birch trees; sweet and paper are the two main ones. Both of them can grow from sixty to eighty feet high. The Indians used the wood to make birch bark canoes. Some make ornaments and small baskets. Siberians collect the sap to make syrup. The Siberian Spruce (Pecia obvobata) is a tall, needle-leaf tree. It can grow to be about 30 meters high. The trunk is about 1.5 meters in diameter. The branches droop down like a pyramid. The thin twigs are yellow-green and are slightly glossy. On the tree, it has pine cones; also, it has pine needles. This tree is important to the industry for the Russian Federation. Moose in the Siberian taiga eat the twigs of trees, but the moose only are found in one taiga. Birds in many taigas eat the seeds of the trees in the area. These trees are also being logged to build houses and for money. A North American fir that has a whitish coloration on both sides of its flat needles. On the tree, the leaves are 2 to 3 inches long and flattened. They are silvery- blue to silvery-green. They curve up from the stem and are very soft. The cones are 2 to 5 inches long and have an olive green to purple color. The wood is used for lumber and the whole tree is often used for Christmas trees. With its sturdy branches and great smell, it attracts many people. White polars don’t live very long. Their wood is light whitish/brownish color and is soft, fairly weak, and light. The leaves are silvery white, and the bark on the branches is plain white. Just like a maple leaf, they have three to five lobes. They grow best in moist places. The trees are used to make boxes and crates. They can also be used to make wood shavings used for stuffing furniture. The White Spruce stiff needles are four-sided, and are less than one inch long. The trees grow very tall and are usually shaped like a pyramid. Some can grow up to 150 feet tall! It is an evergreen color, but some, like the black spruce, are obviously black. These trees are only used as lumber. The Black Bear can run up to 25 miles per hour. They usually weigh between 220-595 pounds. They have rounded ears, short claws that are useful for climbing trees, and a short stubby tail. The bears length is about 5-6 feet from nose to tail, and 32-38 inches from paw to the top of its shoulder. The bald eagle's body length varies from 35 to 37 inches; with a wingspan of 79 to 90 inches. An eagle's average weight is ten to fourteen pounds. Both male and female adult bald eagles have a blackish-brown back and breast; a white head, neck, and tail; and yellow feet and beak. Bobcats are a medium-sized wild cat with males weighing between 11 and 68 lbs, and females weighing between 9 and 33 lbs. Bobcats range between 18 and 23 inches tall at the shoulder and up to 31 inches long from nose to tail. The bobcats’ fur comes in varying shades of brown, gray and white, with spots and stripes of black on the legs. The Canadian Lynx is a medium sized cat and they have a body length between 0.8 and 1 m (about 2.5 - 3.3 ft), a tail length between 5 and 14 cms (about 2 - 5.5 inches) and they weigh between 8 and 14 kgs (about 18 - 31 lbs). They are silver grey/brown in color.
The gray wolf, usually grizzled gray but showing great variation in color, ranges from white to black.They have a long bushy tail with black tip. Their legs are very long. The wolves height is 26 to 38 inches; the length is 4 feet 3 inches to 6 feet 9 inches; their tail is 13 to20 inches; their weight is 57 to 130 pounds.

megnet.net Human Impact The humans had many impacts on the taiga. Some of the things are deforestation (bad), and acid rain (bad). Deforestation is the process of extensive logging in boreal forests that may soon cause their disappearance. Acid rain is also causing significant problems for the Taiga forests. Power plants and factories burn coal and oil. The smoke and fumes from the burning fossil fuels rise into the atmosphere and combine with the moisture in the air to form acid rain. The main chemicals in the air pollution that create acid rain are sulphur dioxide, and nitrogen oxides. The acid rain doesn't kill the tree itself, but it makes the leaves on the trees weaker. After the leaves are poisoned, it limits the nutrients available to the tree. What Is Acid Rain? This size is
the decomposers. This size is the plant eaters. This size is the small predators. This size is the large predators. Dominate Animal The most dominant animal species would have to be the American Black Bear or the Grizzly Bear. They are the most numerous of all the animal species located in the taiga and their fur helps them to adapt well to the environment around them. These bears are important to the ecosystem because they keep all the other animals in the taiga in proportion. Symbiotic Relationship A symbiotic relationship is a relationship that counts on one another. If the grasses in the Taiga were to become extinct, a Cottontail/Showshoe Rabbit would have nothing to eat, becoming extinct itself. A skunk depends on the Cottontail/Showshoe Rabbit for its food. If they had nothing to eat, they'd become extinct as well. Canadian Lynx's and Bobcats eat the Skunks and if there is nothing to eat, they'll become extinct too. Competitive Relationship One competitive relationship in the taiga is the grizzly bear and the black bear. The both eat the same food, so they are constantly fighting for food. If their source ran out, both the grizzly bears and the black bears will both go extinct because they won't have anything to eat. The Grizzly bear has very muscular legs, which allows them to reach up to 35 miles per hour. They have a stout body with a large and round head with small ears. They have many different colors including cinnamon, red, blonde, brown, or sometimes even black. The bear weighs between 330 pounds to 885 pounds and is usually 4.9 to 8.3 feel long!
