Transcript of TAIGA
Our effect on this this biome is not good at all. People see and use the lumber from the taiga trees as a business investment. This lead to deforestation within the forests of the taiga biome.
HOW DOES THE TAIGA AFFECT US?
WHAT WOULD HAPPEN IF THE TIAGA DISAPPEARED?
On the top of the world, just under the tundra biome.
Stretches over Eurasia and northern North America, mostly in the northern part of the Northern Hemisphere, Western North America (Great Basin, Columbia Plateau, Great Plains); Eurasian interior, from steppes of eastern Europe to the Gobi Desert and North China.
Latitude Range: 35° - 55° N.
There are not many plant species in the taiga due to the harsh environmental conditions. Not many plants can actually survive the extreme coldness of the winter in the biome. There are some mosses, but most plants are coniferous trees like pine, white spruce, hemlock, and fir. Even though, there is long periods without water, they get the required amount of water during rains or snow melts
OUR EFFECT ON THE TIAGA
The taiga biome, also known as the boreal forest, is made up of the dense forests of coniferous evergreens along the northern edge of the temperature zone. It is also the largest biome and terrestrial biome in the world!

IMPORTANCE OF THE TIAGA
The major seasons in the taiga biome are winter and summer. The spring and autumn are too short to notice them. That is why there is nutrient-poor soils within this biome. Also, the average temperature for six months out of the year is below freezing!
There are many snow-covered mountains.
There are fjords, which are long, narrow, deep inlets of the sea that are formed by glaciers.
There are also many hills and plateaus.
Spotted with lakes and swamps in the summer.
Winters are bitterly cold with snow
Summers are: mild, warm, rainy, humid, and long enough to allow the ground to thaw.
The average temperature during the winter is -65.2 degrees F to 30.2 degrees F.
The average temperature for the summer can be from 19.4 degrees F to 69.8 degrees F.
There is moderate precipitation as rain and mostly snow.
Staying warm is the major challenge for animals living in the taiga biome. The lakes and swamps during the summer attract birds that feed on insects, fish, or other wetland organisms. Other organisms may migrate to warmer areas in the winter or possibly hibernate. Some animals that live in the taiga year around include: bears, wolves, and moose.
We need this biome because it helps our environment by emitting lots of oxygen, which can help the atmosphere with climate change and global warming.
Humans need this biome because it gives us oxygen, and it takes away carbon dioxide. Without the taiga, the atmosphere would not be as healthy. The taiga is also an important part of research. With its characteristics and the creatures living in it, it is a very interesting subject to study. By understanding how the trees, shrubs, and lichens behave, more solutions to forest fires can be found.
There are many endangered animals within the taiga and a few include: the Siberian tiger, the Peregrine falcon, and the European mink.
A few animals that used to live in the taiga biome are the saber tooth tiger, the wooly rhinoceros, and the Irish deer. These animals are endangered and extinct because of habitat loss from human development, the use of pesticides, and the hunting of their fur.
Some of the plants that became endangered in this biome include: Siberian Dwarf Pine, Long Leaf Pine, and Lady's Slipper Orchid.
If the taiga didn’t exist there would be an estimated 3,200 species that would become extinct. Earth's oxygen level would decrease and air quality would as well.

The taiga is very important for both humans and the environment as a whole because it hosts thousands of organisms who depend on the taiga for survival.
There is little variation in the plant life in the taiga due to the harsh conditions. There are currently no extinct plants but there are many of which may become extinct in the near future because of the freezing climate and deforestation. One example is the Whorled Pogonia.
