Subarctic
Subarctic: a cold, sparsely populated region of taiga, permafrost, and mineral wealth.
Last updated
The subarctic is a geographic and climatic region in the Northern Hemisphere, located immediately south of the true Arctic and north of hemiboreal regions. It covers much of Alaska, Canada, Iceland, the north of Fennoscandia, northwestern Russia, Siberia, and the Cairngorms, generally falling between 50°N and 70°N latitude. The region is defined by low precipitation, taiga vegetation, extreme seasonal daylight, and temperatures above 10 °C for only one to three months per year. Its harsh conditions have shaped sparse human settlement, limited transportation, and economies based on mining, fishing, hydroelectric power, and increasingly tourism.
Precipitation is typically low because cold air holds little moisture, though it is not as dry as semiarid zones. Most rainfall occurs in the warmer months, with a summer maximum that varies from moderate in North America to extreme in the Russian Far East. Glaciers are generally small except in the wettest areas, where they are abundant; during the Pleistocene, glaciation covered even the lowest elevations. Soils are often podsols or, further north, gelisols, and nutrient leaching is common.
The dominant vegetation is taiga forest, as deciduous trees cannot endure the long winters, though in milder areas like northern Norway, broadleaf forest can appear. In waterlogged regions, tree growth fails entirely, leaving peaty herblands of grasses and sedges. Large terrestrial mammals are few, with elk, moose, bears, reindeer, and wolves being the most significant.
Agriculture is mostly limited to animal husbandry, though barley can be grown in some places. Canada and Siberia are rich in minerals such as nickel, molybdenum, cobalt, lead, zinc, and uranium, while the Grand Banks and Sea of Okhotsk support major fisheries. Continuous permafrost is nearly universal except in well-drained areas or those warmed by ocean currents, making construction difficult and expensive.
Cities are few and small, with Murmansk the largest; roads are scarce. Rail transport is limited to lines in Europe, the Norilsk–Dudinka line in Siberia, the Alaska Railroad, and short Canadian routes. Transportation relies heavily on bush planes, helicopters, and riverboats in summer. Exploration of most subarctic regions did not occur until the 18th and 19th centuries, except in parts of Europe with milder winters.

Lore & Background
The subarctic region remained largely unexplored until the 18th and 19th centuries, except for parts of Europe with milder winters due to prevailing wind and ocean currents. Early settlements were mostly created for mining and often did not last long, as seen in abandoned towns of the Yukon, Northwest Territories, and increasingly Siberia.
The Trans-Siberian Railway, skirting the edge of the region, boosted Russian settlement, and intensive industrialization under Joseph Stalin exploited the enormous mineral resources of the Central Siberian Plateau. Today, many subarctic Russian towns are declining as mines close. In Canada, development stalled after early minerals ran out until hydroelectric projects in the 1950s and 1960s, such as those by Hydro-Quebec, which carried out engineering works in near-continuous permafrost but supported little population.
Reader's Guide
The subarctic is significant as a vast, resource-rich zone that has shaped human migration, industrial development, and geopolitical strategies. Its extreme climate—with long, cold winters, short summers, and continuous permafrost—makes building and transportation difficult and expensive, limiting cities to small sizes and roads to few. The region's mineral wealth (nickel, molybdenum, cobalt, lead, zinc, uranium) and rich fisheries (Grand Banks, Sea of Okhotsk) have historically driven settlement and economic activity, though many mining towns are now declining. Hydroelectric power, particularly in Canada, has provided energy but not population growth.
Tourism has recently become a major revenue source, drawn by glacial landscapes and outdoor recreation, despite high costs and inaccessibility. The subarctic's legacy includes its role in the expansion of Russia via the Trans-Siberian Railway, the industrial push under Stalin, and the ongoing challenges of sustaining communities in a harsh environment. Its unique daylight extremes and noctilucent clouds also make it a region of scientific interest.
Did You Know?
- Subarctic regions can experience an all-night period of civil, nautical, or astronomical twilight near the summer solstice, as the sun never dips more than 18 degrees below the horizon.
- Noctilucent clouds are best observed within the subarctic latitude range.
