The Balsam Fir is the third most common tree of the Taiga. Since some uninhabited land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration. Female caribou are the only female deer to grow antlers. The summer temperatures, dominant species, the length of the growing season, and other related aspects vary in the different taiga ecoregions of the world. The central portions of Eurasia and North America are regions of flat or gently rolling topography. In the winter, they hibernate underneath the deep snow.

A well-defined but complex boundary is formed between taiga and alpine tundra on the mountains of the Pacific edge in western North America and the Far East region of Russia. An exception to this progression occurred about 9,000 years ago in western Canada, when white spruce spread rapidly northward across 2,000 km (1,240 miles) of newly deglaciated land in only 1,000 years. . As described in the introduction, taigas are very cold. The subarctic is an area of the Northern Hemisphere that lies just south of the Arctic Circle.The taiga lies between the tundra to the north and temperate forests to the south. Even though their presence is unwelcome to many mammals like caribou, they are a vital food resource for birds and amphibians like frogs. Birds native to the taiga usually migrate south during the freezing winter months. Since this water has no place to drain, more area of the taiga is taken over by muskegs. Chinook salmon are the largest Pacific salmon species and, on average, grow to be three feet (0.9 meters) long and approximately 30 pounds (13 kilograms). As a result, today across Alaska a gradient in plant characteristics can be observed, ranging from typical North American forms in the east to those with Eurasian characteristics in the west.

While beavers are considered to be pests by some, scientists actually have proven that beavers are a "Keystone" species in North America. They can behave aggressively when confronted. Forest management has greatly favoured this species in Scandinavia and Finland.It is a thick-barked species and easily survives light ground . The fact that these animals cannot regulate their body temperature, unlike the warm-blooded animals, makes them easily vulnerable to winters in taiga environs.
