Evidence: 100 • authority: 72

The puna grassland ecoregion, part of the Andean montane grasslands and shrublands biome, is found in the central Andes Mountains of South America. It is considered one of the eight Natural Regions in Peru, but extends south, across Chile, Bolivia, and western northwest Argentina. The term puna encompasses diverse ecosystems of the high Central Andes above 3200–3400 m.

Montane grasslands and shrublands are a biome defined by the World Wide Fund for Nature. The term montane in the name of the biome refers to high elevation, rather than the ecological term that denotes the region below the treeline. The biome includes high-elevation (montane and alpine) grasslands and shrublands around the world, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, and other similar subalpine habitats. Drier subtropical montane grasslands, savannas, and woodlands include the Ethiopian Highlands, the Zambezian montane grasslands and woodlands, and the montane habitats of southeastern Africa. The páram…

Bofedales (singular bofedal), known in some parts of Peru as oconales, are a type of wetland found in the Andes. They feature in the land use and ecology of high Andean ecosystems. They form in flat areas around ponds or streams and may be permanent or seasonal, and they can be man made or natural. Bofedales are associated with organic material in the soil and their green colour often contrasts with that of the drier surrounding landscape. They are found at elevations exceeding 3,800 metres (12,500 ft) above sea level. Bofedales absorb the limited amount of water derived from snow, glacier meltwater and rain showers, storing it in ground and slowly releasing it. Their vegetation is dominate…
