The reserve in the Andean has vegetation consisting of tropical alpine herbs with dwarf shrubs of the forests of Polylepis.
Plant and tree species are reportedly about 190 species, in the harsh terrain, which have emerged given the conditions of salinity, lack of fresh water, low temperatures, and scarcity of nutrients.
Flora restricted to this and other ecoregions include the genera Barneoudia, Hexaptera, Nototriche, Pycnophyllum and Werneria.
The vegetation is characterized by the strong presence of pasture grass (straw) such as Peruvian feather grass (Stipa ichu)  in some plains and hillsides.
The important plant species on which people are dependent for fuel wood in the area is yareta, which grows in the forest of the reserve at 1–3 mm (0.039–0.118 in) per year amidst rocky terrain.
This hardwood tree, which looks like a foamy bubble bath but is as hard as stone, grows slowly, attaining a height of about 5 ft (1.5 m) in height with girth of 10 ft (3.0 m) and can be as old as 3000 years.
In places with higher humidity, Tola or Thola (Parastrephia lepidophylla), Quinoa and Kenua bush tree are found.
The villagers use vegetation as fuel for heating and cooking.
