This is all the Boreal forests in the world,they cover a total of 49.8 million square kilometers. As you can see the Boreal forests cover 33% of the world's land mass.
The Boreal forest is the largest Biome in world. It contains 33% of the world's land mass and it is located between 45 degrees to 65 degrees in latitude.
The Boreal forest has a distinctive feature of marshes and shallow lakes. They form when it precipitates and doesn't evaporate because of the cold weather and vast amount shade form the trees so it eventually form wetlands marshes and bogs.

The rough terrain formed when in the last ice age the ice retreated and the trees slowly grew, the ice left behind a trail of rocks which over time gots covered by soil and formed rough terrain.
Now lets move on to the animals.
Canada's boreal forest is home to 85 species of mammals, 130 species of fish, about 32,000 species of insects, and 300 species of birds
Moose are very strong and sturdy creatures that made its home in the boreal forest. They are 1.4 to 2.1 meters high and weigh around 450 kg. Their fur has adapted structurally to this cold environment by having the fur designed so that there are pockets of air inside them to keep them warm. In fact, their fur is so well heated that if the weather is negative 5 degrees or higher it will feel like a summers day for them. They also gain 20 to 25 percent of their weight before the winter because in the winter most vegetation dies which makes food very scarce.
Russian flying squirrels are small rodents that live most of their lives on the boreal trees. They have a unique str
uctural adaptation. Th
ey have a furry gliding m
embrane attached from their
arms to legs that al
lows them to glide up to 100 mete
rs from tree to

Say hello to the pileated wood pecker. These birds have giant beaks which is one of the most powerful in the woodpecker family. It can carve a giant hole in a tree in little time. The beak is shaped like an triangle which gives it a more powerful impact
The wolverine is a very muscular carnivore. They can hunt down animals that are much more bigger than their size. The wolverine has large paws that can help them not sink into snow that weight up to 32kg and can also move through deep snow 20-25 inches with ease. It has thick waxy fur that resist snow and frost.
Now lets learn about the plants living in this Biome.
The black spruce is a short tree around 20m-25 meters tall. These trees has a diameter of 25cm. They have short waxy needles to prevent water loss and to reject heavy snow fall. They have leaves all year long which allow them to get the early spring warmth and give them an advantage over softwood.
The balsam fir is a common 14-20m tree living throughout the boreal forest. It has a waxy bark which resists freezing
and prevent water loss. The tree like most trees in the Boreal forest. They
needle leaf that also prevent water
earlier. The tree is primarily used for paper production and also for a Christmas tree.
Cattails are wetland plants. They have very hard waxy stalks to keep them warm and prevent water loss. They can reproduce in a rapid speed and their seeds can survive in harsh conditions and multiply. They are seen a lot in the boreal forests because it’s filled with wetlands. But they only grow in the warm summer because they can’t stand very cold weather
The Labrador tea is an evergreen plant that grows in wet and moist soil. It is similar to the the pine trees with the waxy leaves and waxy stalk it’s like a mini tree wont grow as big in size. People harvest this plant mainly for spices on food and use this as herb. They are common in the boreal forest area.
