A physiognomic descriptor of low-growing vegetation beyond the cold limit of tree growth, both at high elevation (alpine tundra) and at high latitude (arctic tundra). Tundra vegetation types are composed of herbaceous plants, shrubs, mosses, and lichens.
A type of ecosystem dominated by lichens, mosses, grasses, and woody plants. Tundra is found at high latitudes (arctic tundra) and high altitudes (alpine tundra). Arctic tundra is underlain by permafrost and is usually saturated. (See 'wetlands')
A treeless area in Subarctic and Arctic regions having permanently frozen subsoil and supporting low-growing vegetation such as lichens, mosses, and stunted shrubs.
treeless, black, mucky soil with permanently frozen subsoil; located in mountainous regions above the timberline
The treeless area to the north of the boreal forest. Tundra vegetation includes low, matted and erect shrubs and herbs such as cottongrass.
A biome found in arctic and subarctic regions consisting of a dense growth of lichens, mosses, and herbs.
The zone of low vegetation in an arctic climate between the limit if the tree zone and perpetual ice or snow ; mountain or alpine tundra is the term sometime used for the corresponding zone on high mountains ( BCFT)
A cold, treeless region of land at high latitudes, supporting only species of shrubs, moss, and lichen capable of living on permafrost.
Treeless area in arctic and alpine regions, varying from bare area to various types of vegetation consisting or grasses, sedges, forbs, dwarf shrubs, lichens and mosses.
The biome that occurs around the Arctic circle, characterized by lichens, mosses, sedges and dwarf trees.
Treeless arctic or alpine biome characterized by cold, harsh winters, a short growing season, and potential for frost any month of the year; vegetation includes low-growing perennial plants, mosses, and lichens.
flat land in the Arctic where no trees grow.
A treeless plain characteristic of the arctic and subarctic regions.
a huge plain that has no trees
a region of high latitude almost devoid of trees resulting from the presence of permafrost
a treeless area near the Arctic where the ground is always frozen and there's very little plant life
a treeless region in a cold climate with a short growing season
vast, treeless plains in Arctic regions and a few other places
A treeless biome mainly in the north polar areas that has long frigid winters and brief summers and where grasses, mosses, lichen, low shrubs, and a few flowering plants survive
Area of land with almost no tree growth that receives less than 25 centimetres of precipitation per year. Arctic tundra is marked by lichens, short grasses and some shrubs.
An arctic environment above treeline with stunted vegetation.
One of the six biomes, tundra is the open Arctic terrain between the treelike and the ice regions of the far north. Shrubs and small vegetation grow on the tundra that covers much of Nunavut, the Northwest Territories and northern Yukon.
the treeless vegetation type characteristic of the arctic region, having a marshy surface where mosses, lichens, berries and low shrubs grow with mucky soil and permafrost underneath.
a flat or rolling treeless plain found in arctic and subarctic regions, usually with black mucky soil and permanently frozen subsoil
A tundra is a cold, treeless area; it is the coldest biome.
a cold climate landscape having a vegetation characterized by the absence of trees. Predominantly occurs beyond the temperature limits of tree growth, north and west of treeline in Alaska, and at elevations above treeline on the mountains; occurs in patches throughout interior Alaska.
A treeless plain in the Arctic regions
Herbaceous and dwarf shrubby vegetation beyond the subpolar tree line.
Treeless zone between the icecaps and taiga.
the treeless region north of the Arctic Circle (arctic tundra) or above the treeline of high mountains (alpine tundra) and also on some sub-Antarctic islands; characterized by very low winter temperatures, short cool summers, permafrost below a surface layer subject to summer melt, short growing season, and low precipitation.
arctic and alpine regions characterized by bare ground, absence of trees, and growth of mosses, lichens, and low shrubs.
biome underlain by permanently frozen ground which prevents nutrient leaching; the tundra vegetation consists of low perennial herbs, shrubs, lichens, and grasses adapted to a very short growing season and tolerant of wet soils.
An area with weather conditions too extreme to allow standing trees. Plant growth is limited to low growing vegetation less vulnerable to wind. Tundra is found in the far north and at high elevations in more southerly latitudes. One of the characteristics of far-north tundra is permafrost, wherein the ground a few inches below the surface is permanently frozen, preventing deep root growth.
Almost treeless plains next to the polar ice. All but the top few inches of soil are permanently frozen.
High latitude biome dominated by a few species of dwarf shrubs, a few grasses, sedges, lichens, and mosses. Productivity is low in this biome because of the extremes of climate.
n. A vast, mostly flat, treeless Arctic region of Europe, Asia, and North America in which the subsoil is permanently frozen. The dominant vegetation is low-growing lichens, mosses, and stunted shrubs.
treeless terrain, with a continuous cover of vegetation, found at both high latitudes and high altitudes.
(Also called arctic desert.) Treeless plains that lie poleward of the tree line. 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.
In physical geography, tundra is an area where the tree growth is hindered by low temperatures and short growing seasons. The term "tundra" comes from Kildin Sami tūndâr 'uplands, tundra, treeless mountain tract'. There are three types of tundra: Arctic tundra, Antarctic tundra, and alpine tundra.
