When the Spanish arrived, they divided Peru into three main regions: the coastal region (11.6% of Peru), that is bounded by the Pacific Ocean; the highlands (28.1% of Peru), that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle (Climate of Peru). But Javier Pulgar Vidal (es), a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions.[1][2] In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.
These eight Peruvian regions are:
- Chala or Coast (subtropical dry and tropical savanna)
- Yungas
- Fluvial Yunga
- Loma-Vegetation
- Quechua
- Suni or Jalca
- Puna
- Janca
- Rupa - Rupa or Highland Jungle
- Omagua or Lowland Jungle

Classic version, Amazonic side edit
- Sea level
- Estimated 22 - 24°C (75°F), but the cold Humboldt Current generates fog on the coast side
- Tierra caliente (Hot land, tropical) up to 2,500 ft (about 750 m - 1,000 m).
- Tierra templada (Temperate land, subtropical) up to 6,000 ft (about 1,850 m – 2,000 m)
- The warmest month has an average temperature of below 22°C or 72°F.
- Crops: Coffee, Tobacco, Maize, Coca, Peruvian Pepper (Schinus molle), Avocado, Guave (Psidium guajava), Cherimoya, Plum, Citrus fruits.
- Tierra fría (Cool land, temperate) below 12,000 ft (about 3,600 m, treeline)
- Tierra helada (Cold land) above 12,000 ft (about 3,600 m)
- Tierra Nevada (Janca), above the snow line, 15,000 ft (about 4,500 m - 5,000 m)
Javier Pulgar Vidal's version edit
The Peruvian geographer Javier Pulgar Vidal divided Peru in 8 regions (traditionally, it was costa, sierra and selva):
Map from República del Perú - Instituto Geográfico Nacional
- Chala (West, Pacific Coast) 0– 500 m
- Omagua (Lowland jungle or Selva baja, Amazonic rainforest) 80– 400 m
- Rupa-Rupa (Highland jungle, Selva alta) 400– 1,000 m
- Yungas (Aymaran for "Warm Lands", Cloud forest)
- Loma-Vegetation (West, "Yunga coastal" at the north of Peru) 450– 600 m
- Fluvial Yungas (East, "Yunga fluvial") 1,000- 2,300 m
- Quechua (East, High valleys) 2,300– 3,500 m
- Suni (or Jalca or Sallqa too, high plateaus and cliffs) 3,500– 4,100 m
- Puna (means "mountain top") 4,100– 4,800 m
- Janca (means white) above 4,800 m, permafrost, rocks, snow and ice[1]

Explanations:
- Region, elevation (m); avg annual precipitation (mm); avg annual temperature (°C);
- Peruvian Highland Rainforest (Tropical climate), Cloud forest (Subtropical climate) and Temperate forest (Temperate climate);
- Cusco reference, estimated avg annual temperature (°C, Lowland Rainforest or Selva baja gets more rain, so it is more cloudy, so it is cooler);
- Snow line reference, Humboldt cold current/ Pacific climate influence, estimated avg annual temperature (°C).[22]
