Wrangle

The Andes Mountains of South America are the longest mountain range in the world. In the high elevation areas these mountains are a complex series of alpine ecosystems. The two Andean regions classified as alpine are the Paramos and Puna. The Paramos are characteristic of alpine regions given their steep topography, harsh climate, poorly developed soils and depauperate flora. However, the Puna holds some controversy as to its classification.
