Tundra

TUNDRA

Human Impact: Land and water are polluted by the oil and gas industry. Hunting and fishing are also issues faced. Hikers can harm the soil that regenerates slowly. Climate change caused by the burning of fossil fuels causes the permafrost to melt. Efforts to Conserve: The Arctic Council promotes sustainable development. The World Wildlife Fund works to protect the North. The Arctic Monitoring and Protection Program and the PEW Environmental Group works to conserve the Tundra.Why it's Important: The air currents from the tropical zone cool in the Tundra and sink back down to the Equator which affects the climate globally.

Precipitation: 4-10in (10-25cm) per yearAverage Winter Temperatures: -34C (-30F)Average Summer Temperatures: 3-12C (35-54F)Growing Season: 50-160 days (during summer)

Human Impact

Plants: Mosses, lichens, grasses, grasslike sedgesAdaptations: They are short and grow together to resist the cold. They carry out photosynthesis at low temperatures and light intensities. Because of the short growing season, they reproduce by budding and division.Animals: Lemmings, weasels, arctic foxes, snowshoe hares, snowy owls, musk oxen, voles, ptarmiganAdaptations: They have additional insulation from fat and coats of thick fur. Many hibernate because of the lack of food in the winter. Birds migrate south.

Relationships

Lemmings, voles, hares, and oxen consume plants. Weasels, foxes, ptarmigan, and owls hunt small herbivores. Caribou graze on sedges, grasses, and dwarf willow in the summer. Bird species feed on the abundant insects.

The tundra occurs in the extreme northern latitudes where the snow melts seasonally.It does not occur in the Southern Hemisphere because there is no land at the corresponding latitudes.
