Treeless terrain, with a continuous cover of vegetation, found at both high latitudes and high altitudes. NSIDCCryosphere

IPCC2014 Treeless terrain, with a continuous cover of vegetation, found at both high latitudes and high altitudes IPAPermafrost Treeless plains that lie poleward of the tree line. (Also called arctic desert.) The plants thereon are sedges, mosses, lichens, and a few small shrubs. Tundra is mostly underlaid by permafrost, with the result that drainage is bad and the soil may be saturated for long periods. It does not have a permanent snow-ice cover.
