The Andes, Andes Mountains or Andean Mountain Range are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,530 mi) long and 200 to 700 km wide and has an average height of about 4,000 m (13,123 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.
The Altiplano, Collao or Andean Plateau, in west-central South America, is the most extensive high plateau on Earth outside Tibet. The plateau is located at the latitude of the widest part of the north–south-trending Andes. The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southwestern fringes lie in Chile.
When the Spanish arrived, they divided Peru into three main regions: the coastal region, that is bounded by the Pacific Ocean; the highlands, that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle. But Javier Pulgar Vidal, a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions. In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.
Lauca National Park is in Chile's far north, in the Andean range. It encompasses an area of 1,379 km2 of altiplano and mountains, the latter consisting mainly of enormous volcanoes. Las Vicuñas National Reserve is its neighbour to the south. Both protected areas, along with Salar de Surire Natural Monument, form Lauca Biosphere Reserve. The park borders Sajama National Park in Bolivia.
Nevado Tres Cruces National Park is a national park in the Atacama Region of Chile, east of Copiapó. It includes Laguna Santa Rosa, Laguna del Negro Francisco, and a part of the Salar de Maricunga. The park is divided into two zones, the northern zone encompassing the southern portion of Salar de Maricunga and Laguna Santa Rosa, and the southern area the Laguna del Negro Francisco. The park is named after Nevado Tres Cruces, which dominates the landscape of the area. The park is managed by the Corporación Nacional Forestal, which offers two refuges in the area: one at the south of Negro Francisco Lagoon and other at the west of Santa Rosa Lagoon. The park is open from October to April.
The puna grassland ecoregion, of the 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.
Llullaillaco National Park is a national park of Chile, 275 km southeast of Antofagasta in the Andes. It lies between the eastern slopes of the Cordillera Domeyko and the international border with Argentina. In the park there are several important mountains that culminate at the summit of Llullaillaco volcano. The park also is characterized by extensive semi-desert plains interspersed by Quebradas. A part of the Inca road system is found in Río Frío area.
Los Flamencos National Reserve is a nature reserve located in the commune of San Pedro de Atacama, Antofagasta Region of northern Chile. The reserve covers a total area of 740 square kilometres (290 sq mi) in the Central Andean dry puna ecoregion and consists of seven separate sections.
Sajama National Park is a national park located in the Oruro Department, Bolivia. It borders Lauca National Park in Chile. The park is home to the indigenous Aymara people, whose influential ancient culture can be seen in various aspects throughout the park. The park hosts many cultural and ecological sites, and is a hub of ecotourism. Many different indigenous plants and animals are exclusive to this area; therefore its continued conservation is of great ecological importance. Management of the park operates under a co-administrative approach, with local people and park conservationists engaging in a constant dialogue regarding park upkeep and policy.
Turco Municipality is the second municipal section of the Sajama Province in the Oruro Department in Bolivia, and was founded on February 15, 1957. Its seat is Turco, situated 154 km west of Oruro at an altitude of 3,860 m. The municipality covers an area of 3,973 km², not taking into account the area of Laca Laca Canton.
The Atacama Desert is a desert plateau located on the Pacific coast of South America, in the north of Chile. Stretching over a 1,600 km (990 mi) strip of land west of the Andes Mountains, it covers an area of 105,000 km2 (41,000 sq mi), which increases to 128,000 km2 (49,000 sq mi) if the barren lower slopes of the Andes are included.
The Eduardo Avaroa Andean Fauna National Reserve is located in Sur Lípez Province. Situated in the far southwestern region of Bolivia, it is the country's most visited protected area. It is considered the most important protected area in terms of tourist influx in the Potosí Department.
The Southern Andean steppe is a montane grasslands and shrublands ecoregion occurring along the border of Chile and Argentina in the high elevations of the southern Andes mountain range.
The Southern Andean Yungas is a tropical and subtropical moist broadleaf forest ecoregion in the Yungas of southwestern Bolivia and northwestern Argentina.
The Central Andean puna is a montane grasslands and shrublands ecoregion in the Andes of southern Peru, Bolivia, and northern Chile and Argentina.
The Central Andean wet puna is a montane grasslands and shrublands ecoregion in the Andes of Peru and Bolivia.
Lake Tauca is a former lake in the Altiplano of Bolivia. It is also known as Lake Pocoyu for its constituent lakes: Lake Poopó, Salar de Coipasa and Salar de Uyuni. The lake covered large parts of the southern Altiplano between the Eastern Cordillera and the Western Cordillera, covering an estimated 48,000 to 80,000 square kilometres of the basins of present-day Lake Poopó and the Salars of Uyuni, Coipasa and adjacent basins. Water levels varied, possibly reaching 3,800 metres (12,500 ft) in altitude. The lake was saline. The lake received water from Lake Titicaca, but whether this contributed most of Tauca's water or only a small amount is controversial; the quantity was sufficient to influence the local climate and depress the underlying terrain with its weight. Diatoms, plants and animals developed in the lake, sometimes forming reef knolls.
The Cordillera Central páramo (NT1004) is an ecoregion containing páramo vegetation above the treeline in the Andes mountain range of northern Peru and southern Ecuador. Due to its isolation there are high levels of endemism. Despite many human settlements and some destruction of habitat by agriculture and mining, the ecoregion is relatively intact.
The Bolivian montane dry forests (NT0206) is an ecoregion in Bolivia on the eastern side of the Andes. It is a transitional habitat between the puna grasslands higher up to the west and the Chaco scrub to the east. The habitat is under severe stress from a growing human population.
Nevado Sajama is an extinct volcano and the highest peak in Bolivia. The mountain is located in Sajama Province, in Oruro Department. It is situated in Sajama National Park and is a composite volcano consisting of a stratovolcano on top of several lava domes. It is not clear when it erupted last but it may have been during the Pleistocene or Holocene.
