By John Lindell; Updated April 24, 2017. However, because there is so much frozen ground and the air is so cold, plants and animals can survive on limited rainfall because the process of evaporation is nowhere near as efficient as in warmer regions.
This map shows the major regions where tundras are most common; tundras are in yellow. Tundra climates receive low levels of precipitation. Many lichens, mosses, and small shrubs flourish in the arctic tundra.
However, research has shown that there are close to 1,700 different varieties of plant that call the tundra home. The tundra may seem tough, but it is a very sensitive environment.
The extreme cold temperature of the tundra means that it does not receive a lot of precipitation, as it is literally too cold for precipitation to fall. The summer growing season is just 50 to 60 days, when the sun shines up to 24 hours a day. Polar bears love to eat fresh, fatty meat.
One of the amazing adaptations of plant life in the tundra biome is that no plants in the area have significant deep root systems, so as to remain in the wet topsoil. With global warming, the fall freeze comes later— in some places recently, not at all —and more of the permafrost is melting in the southern Arctic.

Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Lindell, John.
Northern Exposures. The permafrost melts during the summer, creating swamps, bogs and lakes that breed insects by the millions. Nitrogen and phosphorous take the place of plant life as a basic form of sustenance, as they are nutrients released via the process of decomposition of dead organic matter.
One of the unrelenting features of the tundra is the constant wind.
Sciencing Video Vault. The word tundra comes from a Finnish word that means treeless plain, which is a good description of the biome.
The Arctic's permafrost, the literal foundation for much of the region's unique ecosystem, is deteriorating with the warmer global climate. As we learn more about this unique biome, it is important that we continue to care for it.
Tundra climate is found along the Arctic Ocean and is an extremely harsh climate during the winter. Winter months temperatures are usually between -18 and -50 degrees. Depending on how close to the poles you are, you will experience long days of sunlight in the summer and long nights in the winter months becasue of the angle of the sun.
