    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.

  3. Polar ecology - Wikipedia

    en.wikipedia.org/wiki/Polar_ecology

    Because of the cold weather it is hard for plants to grow. Frozen ground covers most of the polar regions for the majority of the year. Permafrost reaches a thickness of 600–1,000 m (2,000–3,300 ft) deep. Large amounts of permafrost can lead to poor water drainage. Due to the permafrost the water in the soil remains frozen for most of the year.

  9. Barren vegetation - Wikipedia

    en.wikipedia.org/wiki/Barren_vegetation

    Regions on the Earth’s surface where soils are dominating the ecosystems with little to no plant cover are often referred to as “Barren”. These places are areas like deserts, Polar Regions, areas of high elevation, and zones of glacier retreat. For barren zones that are situated in mountain ranges, they are often called the "Subnival Zone ...
