The Kalaallit Nunaat high arctic tundra ecoregion covers the coastal areas of northern including the upper half of the west coast and the upper one-third of the east coast. [1] Greenland (called Kalaallit Nunaat in the Greenlandic language). Areas inland of this strip of land are either covered in ice or bare rock. About one-third of the region is covered by mosses and lichens, and another 3% by herbaceous vegetation and shrubs. The largest national park in the world, Northeast Greenland National Park, protects a majority of the land within the ecoregion. [2] [3] [4] [5] The Pituffik Space Base is also located in this ecoregion. [6]
The ecoregion covers the coastal fringe of Greenland, from 75° N latitude at Melville Bay, around the northern coast to 70° N at Scoresby Bay on the east coast. The coastal bands south of this are in the Kalaallit Nunaat low arctic tundra ecoregion. The coast is rugged, although less so than the south, with deep inlets from the sea. The most ice-free of this coastal band is on the northeast, in the region of Peary Land. The lower soil is permafrost. [5]
The climate of the ecoregion is Tundra climate (Köppen climate classification ET), a local climate in which at least one month has an average temperature high enough to melt snow (0 °C (32 °F)), but no month with an average temperature in excess of 10 °C (50 °F). [7] [8] There is less precipitation than in the south.
Plant life is sparse, with scattered fields of heath and fellfields of low herbaceous cushion plants. There are no trees. Vegetation is strongest on the east coast, with the greatest extents towards the south. Plant adaptations required to live in this harsh environment include tolerating cold, long periods of darkness, and precipitation that mostly falls as snow. [5] 50% of the territory is bare rock and ice, or very sparse vegetation. 30% of the ecoregion has a cover of moss and lichen, and another 3% of herbaceous cover and shrubs. Some small areas on the east coast have greater plant life around hot springs, particularly marsh willowherb ( Epilobium palustre )) and the northern green orchid ( Platanthera hyperborea ). [4]
Studies have identified eight types of vegetation on the east coast from 72 to 79° N:
Over 71% of the ecoregion is officially protected. [4] Portions of the ecoregion lie in:
There are over 190 vascular plant species on the Norwegian Arctic archipelago of Svalbard. This figure does not include algae, mosses, and lichens, which are non-vascular plants. For an island so far north, this number of species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm (4 in)
Sirmilik National Park is a national park located in Qikiqtaaluk, Nunavut, Canada, established in 1999. Situated within the Arctic Cordillera, the park is composed of three areas: most of Bylot Island with the exception for a few areas that are Inuit-owned lands, Kangiqłuruluk, and Baffin Island's Borden Peninsula. Much of the park is bordered by water.
Northeast Greenland National Park is the world's largest national park and the 10th largest protected area. Established in 1974, the national park expanded to its present size in 1988. It protects 972,000 km2 (375,000 sq mi) of the interior and northeastern coast of Greenland and is bigger than all except 29 of the world's 195 countries. It was the first national park to be created in the Kingdom of Denmark and remains Greenland's only national park. It is the northernmost national park in the world and the second-largest by area of any second-level subdivision of any country in the world, trailing only the Qikiqtaaluk Region in Nunavut, Canada.
The following outline is provided as an overview of and topical guide to Greenland:
The Arctic foothills tundra is an ecoregion of the far north of North America, lying inland from the north coast of Alaska. This is permafrost tundra with an average annual temperature below freezing.
Dryas integrifolia is a species of flowering plant in the rose family known by the common names arctic avens, entireleaf mountain-avens, white mountain-avens, northern white mountain avens, and mountain avens. It is native to northern parts of North America, where it occurs from Alaska across Canada to Greenland. It is a common species of the Arctic and it is probably the most common flowering plant on some of the western Arctic islands.
Kandalaksha Nature Reserve is a Russian 'zapovednik' on the south shore of Kandalaksha Bay in the Murmansk and Karelia regions on the opening to the White Sea. The reserve also includes two small sectors on the northern coast of the Kola peninsula on the Barents Sea; notably, the warm Atlantic current causes the northern sectors on the Barents Sea to be warmer than the more southerly White Sea sectors. Over 550 islands are covered in the boundaries of the reserve. It is one of the oldest nature reserves in Russia, created in 1932 to protect the marine habitats and waterfowl of the region, particularly the eider. The reserve is situated in the Kandalakshsky District, Kolsky District, and Lovozersky District of Murmansk Oblast. The nearest city, Kandalaksha, is at the northwest entrance to the Kandalaksha Gulf, about 5 km from the nearest point in the reserve. Since 1976, the reserve has been part of the Ramsar wetland site of international importance "Kandalaksha Bay". It covers an area of 70,530 ha (272.3 sq mi).
Northern Canadian Shield taiga is a taiga ecoregion located in northern Canada, stretching from Great Bear Lake in the Northwest Territories to Hudson Bay in eastern Nunavut. The region supports conifer forests to its northern edge, where the territory grades into tundra. The open forest in this transition zone is characterized by widely scattered, stunted stands of black spruce and tamarack, with some white spruce. The ecoregion lies over the northwestern extent of the Canadian Shield.
The Northeast Siberian coastal tundra ecoregion is an ecoregion that covers the coastal plain of the central north region of Siberia in Russia. This coastal region borders the Laptev Sea and the East Siberian Sea, both marginal seas of the Arctic Ocean, from the Lena River delta in the west to the Kolyma River delta in the east. There are several large river deltas in the area that support breeding grounds for 60 to 80 species of migratory birds. The region is in the Palearctic realm, and the tundra biome. It has an area of 846,149 square kilometres (326,700 sq mi).
The Taimyr-Central Siberian tundra ecoregion is an ecoregion that broadly covers the Taymyr Peninsula in the Russian Far North. It ranges from the delta of the Yenisei River in the west, across the Taymyr Peninsula and Khatanga Gulf, to the Lena River delta in the east. The region is an important area for breeding birds. It is in the Palearctic realm in the tundra biome, and is mostly located in Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai. It has an area of 954,670 square kilometres (368,600 sq mi).
Pacific Coastal Mountain icefields and tundra is a tundra ecoregion in Alaska, British Columbia, and Yukon, as defined by the World Wildlife Fund (WWF) categorization system.
The Iceland boreal birch forests and alpine tundra ecoregion covers the island of Iceland in the North Atlantic. The island is volcanic in origin with basaltic soils, and the cold northerly climate prevents any significant crop agriculture. Because the island is young and isolated from larger land masses, species biodiversity is relatively low. Forest cover has been reduced to about 1% of the original birch forest by a long history of timber extraction and soil erosion caused by sheep grazing. Blanket bogs are common.
The Davis Highlands tundra ecoregion covers the Baffin Mountains on the northeast coast of Baffin Island and Bylot Island, facing Baffin Bay in Nunavut, northern Canada. The terrain is extremely rugged, heavily glaciated, with many deep fjords, and very cold. About half of the territory is moss and lichen tundra, the other half bare rock and ice. The region is wetter than the much drier regions to the southwest of the Baffin Islands.
The Canadian High Arctic Tundra ecoregion encompasses most of the northern Arctic archipelago, from much of Baffin Island, Somerset Island, and Prince of Wales Island in the south, through all islands northward to the most northern island in Canada, Ellesmere Island. Much of the northern islands are covered in ice, and the climate is very dry with as little as 50 mm/year in places. The ecoregion has very little human habitation, and most of the non-ice terrain is moss and lichen cover. The region supports viable populations of arctic mammals such as muskox, arctic wolves, arctic foxes, arctic hares, polar bears, and caribou.
The Kalaallit Nunaat Arctic Steppe ecoregion covers the low coastal areas of western and southern Greenland, reaching in up to 100 km before bare rock and ice become dominant. While much of the ecoregion is bare rock or ice, about 50% of the ground is covered in moss and lichen, and another 10% in herbaceous cover, shrubs, and even small stands of trees.
The Canadian Low Arctic Tundra ecoregion covers a rolling landscape of shrubby tundra vegetation along the northern edge of the mainland Canada along the border of the Northwest Territories and Nunavut, and a small portion in Quebec on the northeast coast of Hudson Bay. The region is important for large herds of caribou and other large mammals, and for large nesting colonies of birds such as snow geese. The region is mostly intact, with 95% remaining intact.
The Canadian Middle Arctic Tundra ecoregion covers a broad stretch of northern Canada - the southern islands of the Arctic Archipelago, plus the northern mainland of Nunavut and, across Hudson Bay to the east, a portion of northern Quebec. This is the coldest and driest ecoregion in Canada, and can be referred to as a 'polar desert'. It is an important region for breeding and migratory birds, and supports 80% of the world's muskox.
The Ogilvie–MacKenzie alpine tundra ecoregion covers the mountainous middle of the Yukon Territory in Canada, with extensions into the Northwest Territories. The vegetation is alpine and subalpine open forest of stunted spruce, fir and pine. The area is rugged but sections appear to have been unglaciated in the late Pleistocene and there are therefore relic species in the region. The area is remote and supports large, sustainable predator-prey systems.
The Torngat Mountain tundra ecoregion covers the Torngat Mountains on the northeastern tip of the Labrador Peninsula where the provinces of Quebec and Newfoundland and Labrador meet. The mountains feature glacially carved U-shaped valleys and deep fjords. The vegetation over most of the territory is that of arctic tundra, herbaceous cover, or bare rock. The region supports seasonal polar bears, black bears, and caribou. The Atlantic coast is on the Atlantic Flyway for migratory birds.
Kytalyk National Park is a protected area for the Arctic breeding grounds of migratory birds on the East Asian–Australasian Flyway, including a significant portion of sites for the critically endangered Siberian crane. The name "kytalyk" is the Yakut-language word for the Siberian crane. The park is on the low-lying tundra of the delta of the Indigirka River, on the East Siberian Sea in northern Russia. The park was officially created in 2019. The park is located in Allaikhovsky District of the Sakha Republic.
