Introduction to Sajama National Park

Sajama National Park

Geographical Location

The Sajama National Park is situated in the northwest extremity of the Oruro department in Bolivia. It is located within the Sajama province and encompasses the municipalities of Curahuara de Carangas and Turco.

It borders the north with the La Paz department and to the west with the Republic of Chile. The geographical coordinates of the reference quadrant of the park are approximately 17° 56′ 57.24″ South latitude and 69° 08′ 31.55″ West longitude to 18° 17′ 37.46″ South latitude and 68° 44′ 25.74″ West longitude. It is nestled in a mountainous and volcanic zone, surrounded by impressive landscapes and unique panoramic views in this region of Bolivia.

Park History

Established on August 2, 1939, through Supreme Decree s/n of 08-02-1939 and Law s/n of 11-05-1945 under the Spanish name "Parque Nacional Sajama," its main objective is to protect the queñua forest (Polylepis tarapacana) and preserve the ecosystems of the semi-arid high Andean region, conserve species of wildlife, protect watershed areas, and promote scientific research. Over time, laws have been enacted to ratify its establishment and expand its scope, encompassing the Mirikiri and Sajama hills.

The central aim of SNP is to support Bolivia’s national conservation goals by safeguarding the biodiversity and ecosystems of the high Andes. It seeks to reconcile human activities with nature conservation, promoting the recovery and development of resource management systems.

Among the park’s management objectives are the protection and preservation of queñua forests, as well as the conservation of threatened or endemic wildlife species. It also aims to safeguard the upper river basins and preserve the region’s cultural and historical heritage. Additionally, programs for environmental education, scientific research, and the development of sustainable models for natural resource use are promoted.

The SNP holds importance not only for conservation but also for tourism. Currently, most visitors come from countries such as France, Italy, Spain, Germany, and Asian countries. However, it’s important to highlight that domestic tourism still constitutes a small proportion of visitors. The development of ecotourism and nature-based recreation is encouraged, always considering the conservation of the area and its resources.

Meaning of the Name "Sajama"

The name ‘Sajama’ is derived from an Aymara deity, reflecting the cultural significance that the park holds in Bolivia. Throughout history, this area has served as a home for diverse indigenous communities, which have cared for and respected this sacred territory.

Geography and Climate

Geography and Topography of the Park

It hosts the highest summit in Bolivia, the Sajama Volcano. This park is characterized by its volcanic geography and the high plateau, dominated by vast plains interrupted by imposing mountains and volcanoes.

Climate in the Park

The climate of Sajama National Park is arid and cold, with extreme temperature conditions. Strong frosts are experienced throughout the year, and cold is constant in the area. The month of January stands out as the wettest, with an annual precipitation ranging between 270 and 400 mm.

Average annual temperatures in the park hover around 10°C, indicating generally cold conditions. However, it’s important to note that temperatures can significantly drop during the night and at higher altitudes, so being prepared for extreme cold is necessary.

A distinctive feature of the climate in this region is the high solar radiation during the day. Due to the altitude and geographic location, the park experiences intense sun exposure, resulting in sunny conditions and clear skies for much of the year.


Situated within the endorheic Altiplano watershed, the region’s waters do not drain towards the sea but accumulate in lagoons and salt flats within the high plateau itself.

The most important rivers that cross the park are the Sajama River and the Turco River. These rivers are fed by the melting of the Sajama and Payachatas snow-capped mountains located in the region. The waters from these rivers eventually drain into the Sajama and Tomarapi-Cosapa basins.

The hydrographic basins of Sajama National Park are crucial for maintaining water resource quality and ecosystem balance in the region. Additionally, the lagoons and salt flats present in the high plateau also contribute to the diversity of landscapes and habitats within the park.

Biodiversity: Ecosystems, Flora, and Fauna


The ecosystems present in Sajama National Park are representative of the Bolivian high plateau, including puna grasslands, wetlands, and bofedales (peat bogs), the latter being essential for the survival of high Andean fauna.

It is part of the Southern Puna Ecoregion, an ecological region that spans various areas of the Andes in Bolivia, Peru, Chile, and Argentina. This ecoregion is characterized by its high altitude and cold, dry climate, with vegetation adapted to the extreme conditions of altitude. It also belongs to the Subecoregion Desert Puna with Snow and Subnival Zones, encompassing desert and semi-desert areas where snow and subnival zones (areas below the snowline) are found. This altitudinal variation gives rise to different types of vegetation, including the High Andean Vegetation of the Western Cordillera.


Plant species in Sajama adapt to the extreme conditions of the desert puna, one of Bolivia’s driest areas. Examples include the queñua forests (Polylepis tarapacana), open and shrubby woodlands. These forests are found at elevations between 4,200 and 4,800 meters above sea level and surround the Sajama snow-capped mountain. Other species present in this unit are Azorella compacta, Deyeuxia cabrerae, Deyeuxia brevifolia, Parastrephia quadrangularis, Chersodoma jodopappa, Senecio puchii, and Perezia purpurata.

There are also semiralos and ralos queñuales, which are similar to queñuales but with smaller and less dense queñua trees. Other vegetation units include high and low rocky hill vegetation, tholares of Parastrephia lepidophylla, tholares of Fabiana densa, tholar-pajonal, scree vegetation, Iru-huichu grasslands, high Andean bofedales, and saline bofedales on plains and valleys.

In areas with scarce vegetation, there are lagoons with shoreline vegetation dominated by Elodea sp., and kollpares, which are plains adjacent to bofedales with saline vegetation like Salicomia sp., Poa sp., and Distichlis humilis.

These different vegetation units reflect plant adaptation to extreme conditions of drought, low temperatures, and altitude in the park. Each of them plays an important role in the ecosystem and contributes to the diversity and resilience of flora in this area.


The park hosts a variety of fauna species adapted to puna conditions. Some of these species are threatened and are listed under CITES and IUCN.

Only two native fish species have been recorded in the park: burruchyalla (Orestias sp. group agasii) and suche (Trichomycterus sp.), which inhabit different bofedales in the area.

The presence of amphibians and reptiles in the area is limited. Among the amphibians are Pleurodema marmorata and Telmatobius marmoratus, while the reptiles present include Liolaemus signifer, L. alticolor, Velosaura jamesi, and Tachymenis peruviana.

There are 71 species of birds recorded in the park. Notable among them are the suri (Pterocnemia pennata) and the Andean flamingo (Phoenicoparrus andinus), both of which are threatened.

A total of 27 mammal species inhabit the protected area of Sajama National Park, including the Andean armadillo (Chaetophractus nationi), taruca deer (Hippocamelus antisensis), Andean mountain cat (Oreailurus jacobita), and vicuña (Vicugna vicugna). However, it’s important to note that populations of armadillos, pumas, and vicuñas have shown signs of recovery in recent years. Additionally, the Andean fox (Pseudalopex culpeus), ferret (Galictis cuja), and skunk (Conepatus chinga) are common in the area.

These fauna species, whether threatened or more common, contribute to the biological diversity and ecosystem balance of the region.

Population in the Park

Socioeconomic and Demographic Context

According to the 2002 National Population and Housing Census, a population of 5,278 people was recorded in the municipality of Curahuara de Carangas, with 54% men and 46% women. However, data from GRAMA in 1997 showed a population of 2,132 inhabitants in the protected area.

In terms of health services, it has been observed that the majority of the population lacks proper sanitation facilities and uses latrines, especially in areas with higher tourist influx.

Regarding the supply of drinking water, most cantons do not have piped water supply and rely on springs, sources, and rivers. Larger population centers such as Cosapa, Lagunas, and Sajama have access to piped water outside homes.

Until a few years ago, the area lacked an electrification system, except for the fuel-powered generators used in ranger shelters. Currently, larger settlements have electricity.

A decrease in the use of vegetal fuels as an energy source has been observed in recent years, replaced by liquefied gas, kerosene, and others. However, people with low resources tend to maintain the traditional practice of using plant materials as an energy source.

The literacy rate reached in the area was 14.6% in 1992, below the department’s average. Localities with the highest number of illiterates are in the northern zone, such as Huaylluma, Sajama, and Chajalla, while Lagunas and Cosapa have a lower proportion of illiterates (7%). These results are related to proximity to educational centers. Most individuals have received education only up to the basic level, while a smaller percentage has reached intermediate and secondary levels.

The park is home to five communities that contribute to fauna and flora protection, with their main source of income being tourism. These communities have constructed accommodations for tourists and also offer traditional meals based on llama and alpaca meat.
