With m ore than 500 species in the Arctic, lichens are a vital food source for herbivores in the tundra.

What are the major land features of the tundra?

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. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

What are some habitats in the tundra?

What happens to the soil in the Arctic tundra?

The treeless arctic and alpine tundra environment is severely cold in winter. In the tundra, soil water is solidly frozen for many months. During the short summer season, however, the surface thaws, leaving the soil saturated and vulnerable to mass wasting and water erosion.

What kind of plants live in the Arctic tundra?

There is low diversity in organisms that live here, but many still flourish. Many lichens, mosses, and small shrubs flourish in the arctic tundra. The plants that live in the harsh permafrost soil usually adapt to the weather by being short and grouped together to resist winds and to be protected.
