Typical Soil Type
Topsoil is generally poor in nature due to continual permafrost.
Soil in this biome is very acidic and in turn decreases the plants' sustainability.
Generally:
Right below the topsoil would be humus.
Below that would evidence of lost minerals through leaching.
Below that would be a deposit of minerals.
And the bottom would consist of mainly rocks and stones.
Global Wind Currents
Coniferous forests are subject to maritime polar win masses and continental polar patterns.
In turn, they are receiving a combination of dry air from the land and moist air from the ocean.
Trade winds and Westerly winds create a continual circular pattern of wind flowing clockwise in the Northern Hemisphere.
Ocean Currents
The ocean currents are generally colder and less prone to evaporate, due to the fact that the currents near the coniferous forests are more along the Northern Hemisphere.

Habitat Destruction
In all areas, small-scale, clear-cut foresting is a key issue.
Freshwater ecosystems, a part of the Boreal Forest, is threatened because of this.
However, most parts of these forests have been kept relatively untouched due to unfavorable, rural conditions. Some areas are discerned to be 90% ~ 99% intact.
Some areas like the Western Siberian Hemiboreal Forest are threatened because of fires.
These fires are most likely man-made.

Introduced/Invasive Species
For plants, many types of vegetation brought in by humans quickly overpower native plant life.
Reindeer were imported into Iceland's forests in the 18th century and continue to spread across the country.
American Minks eat birds that consist of their diet.

Reindeer
Population Growth of Humans
While the areas are fairly isolated, humans have started to creep into this biome.
Possible jobs in foresting have sprung up as more and more forest is being cut down.
Lodging for humans has also been thrown into this mix.
Reindeer herding has become a "suitable" way of travel.
Demand for Hydroelectric power divert streams and rivers unnaturally.
Pollution
Water pollution from lumber extraction is common in this area.
Many oil and gasoline drills/refineries may pose a threat in the near future.
Over-Consumption of Natural Resources
Overall, the consumption of resources is generally quite low, but problems still do exist.
Humans consume animals for recreational hunting.
This causes a displacement in animals such as moose and caribou, which in turn increases the population of higher-level predators such as Brown bears (Denali Highway).
Regulations are in place to regulate recreational hunting.
Coniferous Forests
Just like the wind currents, the ocean currents nearing the biome also rotate in a clockwise manner.
