Location & Description: ➢ Kalaallit Nunaat of the high arctic tundra is located in Northern Greenland. Greenland is the largest island in the world. Although 80% of the island is beneath the second largest ice cap in the world. ➢ It is located 75 N at Melville Bay on the west coast and 70 N at Scoresby Sound on the east side. There are ice sheets that extend all around the northeastern coast. The high arctic region is less mountainous than the southern area, with rolling hills. ➢ Most of Greenland is above the arctic circle, and many of the northern regions are subject to Midnight-suns and polar nights in the summer. The famous Northern lights or the Aurora Borealis is also located in Melville Bay. The colored lights are seen due to ionized low-temperature molecules being powered by solar and cosmic radiation. “Kalaallit Nunaat High Arctic Tundra | Ecoregions | WWF.” World Wildlife Fund Kalaallit Nunaat the High Arctic Tundra “Where The Northern lights shine brightly in Melville Bay” By Name Environmental, Social, Economic ● People in Northern Greenland were negatively impacted by their ecosystem negatively. Hunters have decreased the population of many mammals. Hunters were then not allowed to hunt animals because of the population decline.But recently, Hunters are able to hunt animals under some regulations in the national park of East and North Greenland. ● Greenpeace's anti-sealing and anti-whaling campaigns have destroyed Greenland’s economic base. Which was 80% of North Greenland’s Income. ● Oil and Mining companies have targeted the high arctic tundra to build roads, housing, and sites of garbage waste that have polluted the region. Akihito, Takaba. “Life in The High Arctic Tundra of Northeastern Greenland.” Plants: Plants are only able to survive in this extreme environment for months without sunlight. these plants include Cassiope Tetragona and Salix Arctic. Animals: Arctic Wolf (Canis Lupus): The Arctic wolf has white fur for camouflage to blend in with their environment. They also used caves and rocks for shelter and to reproduce (Mitchell, P. 2017, Oct.19). Muskox: 40% of the muskox population lives in the national park of north and east Greenland. They are able to rely on their fur coat for protection in arctic blizzards. They live in a herd of 10 to 20 muskoxen. When threatened by wolves or humans, they face their predators with their heads down (Worldwildlife.org). Decomposer: Nematodes, Lichens Mitchell, Peter. “Facts About Tundra Wolves.” Pets on Mom.Com, 19 Nov. 2020 Climate: The climate of Northern Greenland, is a polar desert with devastating temperatures during the winters and summers at 5 degrees Celsius. Föhn winds are dry, warm air masses that remove melting ice on top of the ice caps and raise temperatures by 10-20 degrees celsius (Worldwildlife.org). Soil: The lower layer of the soil is permanently frozen which is called permafrost. Rainfall: In Greenland, the rainfall decreases as the arctic desert occurs near the ice cap. “World Species: Ecoregion: Kalaallit Nunaat High Arctic Tundra.” Worldspecies.
