The Tundra

The worlds youngest biome

Some characterizations of the tundra are extremely cold climate, Low biotic diversity, Simple vegetation structure, Limitation of drainage, Short season of growth and reproduction, Energy and nutrients in the form of dead organic material, and Large population oscillations.

The tundra is the worlds youngest biome, it was formed only 10,000 years ago.

Tundra comes from the Finnish word "tunturia", which means a barren land.

location, climate, vegetation, and animal life

The tundra is located at latitudes 55° to 70° North, the tundra is a vast and treeless land which covers about 20% of the Earth's surface, circumnavigating the North pole. Average annual temperatures are -70°F (-56°C).

Plants that are commonly found in the tundra biome include dwarf shrubs, grasses, mosses and lichens.

The plants and few trees that are found in the tundra have developed important adaptations that have made it possible for them to survive in this harsh environment. The trees that can survive in the tundra are often small, which reduces the damage caused by wind and makes it possible for these tress to be covered in snow during the winter. Although it would seem that being covered in snow would make the trees colder, in fact, the snow acts as insulation for the trees and helps them stay warmer during the winter months.

The animal life in the tundra include polar bears, caribou, arctic hares, musk ox's, rock ptarmigans, snow owls, and my personal favorite arctic foxes. All these animals have learned and adopted the the harsh cold tundra.
