Tundra, a cold region of treeless level or rolling ground found mostly north of the Arctic Circle or above the timberline on mountains. Tundra is known for large stretches of bare ground and rock and for patchy mantles of low vegetation such as mosses, lichens, herbs, and small shrubs.

tundra, Treeless, level or rolling ground above the taiga in polar regions (Arctic tundra) or on high mountains (alpine tundra), characterized by bare ground and rock or by such vegetation as mosses, lichens, small herbs, and low shrubs. Animal species are limited by harsh environmental conditions.
Tundra climate, major climate type of the Köppen classification characterized by sub-freezing mean annual temperatures, large annual temperature ranges (but not as large as in the adjacent continental subarctic climate), and moderately low precipitation. The tundra climate region occurs between 60°.
The tundra is a large, barren region with no trees. In fact, the word tundra comes from the Finnish word tunturia , which means “treeless plain.” Areas of tundra lie between the permanent ice of the far north and the northern forests of North America, Europe, and Asia.
The tundra is an area of treeless, level or rolling ground found in cold regions. It accounts for roughly 10 percent of Earth’s surface. The two major tundra zones are the Arctic tundra, found mostly north of the Arctic Circle, and the alpine tundra, located above the timberline on high mountains ( see Arctic regions ).
TUNDRA meaning: a large area of flat land in northern parts of the world where there are no trees and the ground is always frozen.
Permafrost forms and exists in a climate where the mean annual air temperature is 0 °C or colder. Such a climate is generally characterized by long cold winters with little snow and short, relatively dry, cool summers. Permafrost, therefore, is widespread in the Arctic, subarctic, and Antarctica.
The taiga biome consists of three roughly parallel zones: closed-canopy forest, lichen woodland or sparse taiga, and forest-tundra. The closed-canopy forest is the southernmost portion of the taiga.
