Tundra Biome Description
Limitation of drainage.Short season of growth and reproduction.Energy and nutrients in the form of dead organic material.Large population oscillations.
The Tundra is cold through all the months of the year. Summer is a brief period of milder climates when the sun shines almost 24 hours a day. Even the sun can`t warm the tundra much. The short summer lasts only 6-10 weeks. It never gets any warmer than 45 or 50° F. During the winter the sun rarely comes out and it is dark most of the day. Winter temperatures do not reach above 20° F and average -20° F to -30° F. The Tundra has a cold and dry climate. precipitation totals 6 - 10 inches of rain a year, which includes melted snow.
Plant cover, rocks and places of water naturally thawing and freezing patterns of the ground. the ground is pushed and pulled producing tiny hills, valleys, slopes and porous regions. Continuous thawing and freezing force fragments of stone outward in a ringed pattern forming Frost Boils.
Arctic Moss, is an aquatic plant found growing on the bottom of the tundra lake beds and in and around bogs. They have tiny roots, tiny leaves and no flowers.
Bearberry, is a low growing evergreen that has thick bark, leathery leaves and a flower that has five pedals in a pale pink or white color. These are normally found in dry non-nutrient soil.
Labrador Tea, the plant will grows to be 4-5ft in the southern latitudes of the tundra and will creep over the ground like carpet in the northern latitudes. It has woolly branches with narrow leaves and at the end of each branch are tiny clusters of white flowers.
The Snowy Owl, have large yellow eyes set in front of the face, and large ears hidden under dense white feathers. They weigh 4-6 pounds and stand 21-26 inches tall.
Harlequin Duck, get it`s name from the colorful costumes worn by harlequins. They have a buoyant, compact body with strong webbed feet and weigh 1-1.5 pounds.
Ermine, part of he weasel family and prefers cold northern climates. It`s coat is a chocolate brown with a white under belly. The Ermine weighs between 3-13 ounces and is 7-13 inches long.
More people have recently been populating the tundra to work in mines and in the oil industries. The development of new towns and roads have interrupted many of the animals migration and feeding patterns and has also caused damage to the permafrost. The continuing growth in population and industry threaten the future existence of the tundra.
