flora and fauna
With most of the park well above 3,500 m in altitude, the vegetation is typical of the tropical high Andes with scrubby woodlands in protected valley areas and open grasslands covering the lower slopes of Cotopaxi and other peaks. The landscape of the Paramo is an important feature of the park, a natual water filtering system for the streams coming off Cotopaxi's glacial areas. That water is an important part of Quito's water supply.
A number of rare Andean species are protected in the park including infrequently seen condors, spectacled bear, and brocket deer along with more commonly viewed foxes, white tail deer and rabbits.
