The Arctic tundra ecosystem, found in the far north polar area of the world, is characterized by cold temperatures, frozen soil called permafrost and harsh conditions for life. SeasonsThe seasons in the Arctic tundra include a long, cold winter and a short, cool summer. Animal AdaptationsAnimals living in the Arctic tundra have developed adaptations including heavy winter coats, camouflage that changes color with the seasons, efficient body shape to prevent heat loss and the ability to build insulated tunnels underground. Web of InteractionsThe plants and animals of the Arctic tundra interact over large areas to create a food web that helps all of its members survive the harsh conditions.
Some flowering plants have fuzzy coverings on the stems, leaves and buds to provide protection from the wind. Flowering plants use the long hours of sunlight to produce flowers quickly in the short growing season.
Some plants have cup-shaped flowers that face up to the sun, so the sun's rays are directed towards the centre of the flower.

Trees can't grow high in the mountains because the temperatures don't stay warm enough long enough for the trees to grow. In the winter, few plants and animals can survive, so many plants remain dormant through winter and many Arctic tundra animals hibernate or migrate at that time.
The small plants of the tundra use the tactics of dormancy, only producing seeds every few years, turning with the sun to absorb energy and developing protective coverings. Because they are so specialized to life in tundra conditions, many animals and plants may not survive if these conditions change. The land above this tree line on a mountainside forms alpine tundra or high-altitude tundra. The area can be quite wet and boggy, because the moisture doesn't drain into the frozen ground. Arctic tundra occurs in the far northern areas, or what is called high latitudes of the earth.

They offer lots of food for the millions of migrating birds that nest in the arctic each summer. The permanently frozen ground in these regions does not allow the tree roots to grow deep enough to support the growth of trees.
So you either slog though the bog around the plants or try to walk across the tops of the plants. You might be tempted to step across the mounds like you might step across rocks in a stream. They grow low to the ground to avoid the near constant winds that roar across the treeless tundra.
