Characteristics of tundra include:

  1. Extremely cold climate
  2. Low biotic diversity
  3. Simple vegetation structure
  4. Limitation of drainage
  5. Short season of growth and reproduction
  6. Energy and nutrients in the form of dead organic material
  7. Large population oscillations

Ecological Warrior

The melting of the permafrost as a result of global warming could radically change the landscape and what species are able to live there. Ozone depletion at the North and South Poles means stronger ultraviolet rays that will harm the tundra.
