Setting

The landscape in this ecoregion consists of high mountains with permanent snow and ice, meadows, lakes, plateaus, and valleys. It transitions to the Central Andean wet puna to the north and the Central Andean dry puna to the south. Elevations range from 3,200 to 6,600 metres (10,500 to 21,700 ft).[2]

Climate

The climate is Köppen climate classification cold semi-arid. Precipitation ranges from 250 to 500 millimetres (9.8 to 19.7 in) per year.[2]

Flora

Flora consists typically of open meadows with rocks, bunchgrass, herbs, moss, and lichen. Grasses are represented by the genera Calamagrostis, Agrostis, and Festuca. Parastrephia lepidophylla and Margyricarpus are small bush species found here. Azorella compacta and Puya raimondi are shared with the wet puna. Polylepis, Buddleja, and Escallonia are trees found at lower elevations.[2]
