View of a typical tundra environment in Greenland, with a glacier visible in the background. Tundra is the name given to a region spreading across North America and Eurasia where the ground is frozen all year (permafrost). With too severe a climate for trees to grow, tundra lands support hardy vegetation such as moss and lichen, although during the brief summer many flowering plants appear when the top few centimetres of soil thaw.

Denali National Park and Preserve in Alaska, USA. Opened in 1917 as Mount McKinley National Park (North America's highest mountain lies within its 6 million acres/2.4 million ha), this sub-arctic landscape of tundra, waterlogged ground, and permafrost was designated an International Biosphere Reserve in 1976.
Region in high latitudes with almost no trees – they cannot grow because the ground is permanently frozen (permafrost). The vegetation consists mostly of grasses, sedges, heather, mosses, and lichens. Tundra stretches in a continuous belt across northern North America and Eurasia. Tundra is also used to describe similar conditions at high altitudes.
