  1. Tundra By: Donald Harold

  2. The Tundra • A Tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. There are three types of tundra: arctic tundra, alpine tundra, and Antarctic tundra. In a tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra’s.

  3. Arctic Tundra • Arctictundra is found across northern Alaska, Canada, and Siberia. This biome has long cold winters and short cool summers. The Arctic tundra has low precipitation (less than 10 inches per year) and dry winds. These conditions make the Arctic tundra a desert-like climate

  4. Alpine Tundra • Alpine tundra is a type of natural region or biome that does not contain trees because it is at high altitude. Alpine tundra is distinguished from arctic tundra, because alpine soils are generally better drained than arctic soils.Alpine tundra transitionsto subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotoneare known as Krummholz. With increasing elevation it ends at the snow line where snow and ice persist through summer.

  5. Unique Facts About The Tundra • The Tundra Biome is the 2nd most deadliest environment. • The Tundra Biome has only 6 weeks of summer. • There is little to no precipitation. • The soil has very little nutrients for plants. • It the least inhabited by humans biome. • The Tundra Biome is the biome most affected by human pollution. • The sun is almost 24 hours up a summer day, meaning that there are mostly no nights. • During the winter, this biome has few hours of sunlight. • The Tundra Biome is covered permanently by a frozen layer of soil. • The Tundra Biome is the most vital role in keeping global temperature at a stable place.

  6. Humans Affect the Tundra Biome • Humans affect the tundra biome in several ways including development by drilling for oil and building pipelines, which reduces the habitat. Global warming and climate change affect thawing of permafrost. Overfishing and hunting affects the ecosystem of the tundra biome.

  7. Producer Consumer • Life in any biome includes producers (plants and other photosynthetic organisms) and consumers (organisms that obtain their energy from producers).
