It extends south to the edge of the taiga a biome characterized by coniferous forests. The division between the forested taiga and the treeless tundra is known as the timberline or tree line. Location of arctic tundra across the Northern Hemisphere. The tundra is known for cold conditions, with an average winter temperature of degrees F degrees Cand an average summer temperature ranging from 37 degrees to 54 degrees F 3 degrees to 12 degrees C.
The growing season lasts from 50 to 60 days. The biome is also characterized by desertlike conditions, with an average of six to ten inches 15 to 25 cm of yearly precipitation, including snow melt. Winds often reach speeds of 30 to 60 miles 48 to 97 km an hour. Another hallmark of the tundra is permafrost, a layer of permanently frozen subsoil and partially decayed organic matter.
Only the top nine or ten inches of soil thaw, leading to the formation of bogs and ponds each spring. Ice wedges in the permafrost can crack and cause the formation of polygonal ground. This picture also illustrates the formation of ponds as the snow melts each spring.

Warming Arctic temperatures due to climate change are causing the permafrost to thaw, releasing the carbon in the form of carbon dioxide a greenhouse gas. Additional carbon dioxide in the atmosphere will intensify warming, leading to increased thawing and the release of even more carbon dioxide.

This positive feedback loop thus has the potential to significantly increase the rate and effects of climate change. Approximately 1, species of vascular plants are found across the Arctic tundra, including flowering plants, low shrubs, sedges, grasses, and liverworts.

Migration means that Arctic populations are in continual flux. A generalized food web for the Arctic tundra begins with the various plant species producers. Herbivores primary consumers such as pikas, musk oxen, caribou, lemmings, and arctic hares make up the next rung.
Omnivores and carnivores secondary consumers such as arctic foxes, brown bears, arctic wolves, and snowy owls top the web. Bacteria and fungi play the important role of breaking down organic matter and returning nutrients to the soil for re-use.
Of course, the exact species involved in this web vary depending on the geographic location. A generalized tundra food web. Exact relationships and species depend on geographic location. The interconnected nature of a food web means that as numbers of one species increase or decreaseother populations change in response. An often-discussed tundra example is the lemming population. Lemmings are small rodents that feed on plants. Populations of lemmings fluctuate radically from large populations to near extinction in regular intervals.
