Tierra helada


Tierra helada

Tierra helada (Spanish for frozen land) is a term used in Latin America to refer to the highest places found within the Andes mountains.

Tierra helada is for the Montane grasslands and shrublands, Sunis, Punas and Paramos between the Treeline and the Snow line. The term "Tierra nevada" is accurate from a climatological standpoint, as its land is indeed "frozen," situated above the snow line. In the northern Andes, the latter is located at an altitude of approximately 15,000 ft (or about 4,500 m).[1][2][3][4]

The peruvian geograph Javier Pulgar Vidal (Altitudinal zonation) used following altitudes:

  • 1,000 m as the border between the Tropical Rain forest and the Subtropical Cloud forest
  • 2,300 m as the end of the Subtropical Cloud forest (Yunga fluvial)
  • 3,500 m as the Treeline
  • 4,800 m as the Puna end [5]
