Adventures In the Artic Tundra By: Shanen C, Breandra Bn, Yasmin N
Description of the Biome <ul><li>The Artic Tundra is the worlds youngest biome. It was formed 10,000 years ago. The Artic Tundra has very little rainfall. It also has poor nutrients in the soil. It has an under layer called permafrost, which stays frozen all the time. </li></ul>
Description of Typical Plants <ul><li>The Artic Tundra isn’t the best place to for plants to grow because of permafrost (soil being frozen), so most plants roots can not grow out. Which make them very short in height. </li></ul><ul><li>Most of the plants are short and grouped together to resist the cold temperatures and snow during the winter. Examples:Reindeer Moss </li></ul><ul><li>Lichens, Sedges and cushions. </li></ul>
Reindeer Moss <ul><li>Reindeer moss is a lichen that forms pillow like colonies of dense branching ground cover. </li></ul><ul><li>It has no leaves and the stems are shallow, and branch in pairs. </li></ul>The picture above is reindeer moss.
Plant 2 This plant is called cushion .Many of the plants are cushion type. Cushion means they grow in a low, light clump and looks like a cushion. They are more common in the Tundra biome and there growth help them protect them from the cold
Plant #3 Sedges <ul><li>Resembles to grass </li></ul><ul><li>Can only reach to 4feet </li></ul><ul><li>Steam are triangular </li></ul><ul><li>Spikes on upper Section </li></ul>
Description of Typical Animals <ul><li>Most of the animals adapt to their environment because they have a layer of blubber that keeps them warm during the winter. Such as: polar bears, caribou, musk ox, grey wolves, lemmings, and rabbits. </li></ul><ul><li>Birds migrate to the south during the cold harsh weather. Such as: birds, penguins, falcons, ravens, terns, and loons. </li></ul>
Description/Picture of Animal <ul><li>The polar bear has a creamy white coat. It has many prey and eats berries and leaves of the tundra plants. They mate in midsummer with a litter of one to four young. They remain with their mother for a year, which means she breeds only every other year. </li></ul>
Aminal # 2 The artic fox has adapted to its environment by growing long fur that changes color with the season.

Human Impact <ul><li>The human impact on the tundra is based on when humans drill to get their natural resources such as petroleum, oil, etc… Also is causes climatic changes and ruins the equilibrium of the ecosystem </li></ul>
Interesting Facts <ul><li>The Artic Tundra is the youngest Tundra. </li></ul><ul><li>The Tundra is a vast and treeless land which covers about 20% of the earths surface. </li></ul><ul><li>The Tundra is very cold and the land is pretty stark. </li></ul>
