  2. Tundra of North America - Wikipedia

    en.wikipedia.org/wiki/Tundra_of_North_America

    Average summer temperatures range from 37 °F (3 °C) to 60 °F (16 °C). The tundra is very much like a desert in terms of precipitation. Yearly average precipitation varies by region, but generally, there is only about 6–10 inches (150–250 mm) of precipitation per year, and in some regions, it can have up to 20 inches (510 mm).

  3. Arctic ecology - Wikipedia

    en.wikipedia.org/wiki/Arctic_ecology

    Average precipitation ranges from 20 to 30 cm (8 to 12 in), [43] and the permafrost can be "several hundred meters" thick. [42] Plant species supported by tundra are generally short, lacking stems due to threats posed to vascular structure by frozen temperatures, and much of their growing matter is found below the soil. [44]

  4. Tundra - Wikipedia

    en.wikipedia.org/wiki/Tundra

    Alpine tundra transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone (the treeline) are known as Krummholz. Alpine tundra can be affected by woody plant encroachment. [27] Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by plants that grow close ...

  5. Canadian Arctic tundra - Wikipedia

    en.wikipedia.org/wiki/Canadian_Arctic_Tundra

    Rainfall in the Canadian Arctic has increased by more than 20% in the last decades. However, the degree of rainfall increase is subject to variation from one location to the next. For example, in Resolute, Nunavut in the period of 1948 to 2007, there was a 48% increase in rainfall recorded with an average of 13.6 mm (0.54 in) of rain per decade.

  6. Climate and vegetation interactions in the Arctic - Wikipedia

    en.wikipedia.org/wiki/Climate_and_Vegetation...

    Papaver radicatum (arctic poppy), a flowering plant of the Arctic tundra follows the sun around the sky during the 24-hour daylight of summer north of the Arctic Circle. Changing climate conditions are amplified in polar regions and northern high-latitude areas are projected to warm at twice the rate of the global average. [1]

  7. Arctic vegetation - Wikipedia

    en.wikipedia.org/wiki/Arctic_vegetation

    Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow. [7]

  8. Taiga - Wikipedia

    en.wikipedia.org/wiki/Taiga

    The average time within a fire regime to burn an area equivalent to the total area of an ecosystem is its fire rotation (Heinselman 1973) [46] or fire cycle (Van Wagner 1978). [47] However, as Heinselman (1981) noted, [ 45 ] each physiographic site tends to have its own return interval, so that some areas are skipped for long periods, while ...

  9. High Arctic tundra - Wikipedia

    en.wikipedia.org/wiki/High_Arctic_tundra

    The maximum elevation is 1,633 metres (5,358 ft). The ecoregion to the north on Baffin Island is the Davis Highlands tundra, which receives more than twice as much precipitation (400-600 mm/year). [6] The terrain varies across the ecoregion. The north and west is mountainous and heavily covered in ice.
