Llullaillaco National Park
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. Vegetation The park lies within the Central Andean dry puna ecoregion. In the park have been recorded 126 flora species, 21 of which are endemic to the area. Access To access this area, the travel must be programmed and have official permission from the CONAF (National Forest Guard of Chile) in Antofagasta City.

Antofagasta Region
The Antofagasta Region ( es, Región de Antofagasta, ) is one of Chile's sixteen first-order administrative divisions. The second-largest region of Chile in area, it comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá, by Atacama to the south, and to the east by Bolivia and Argentina. The region's capital is the port city of Antofagasta; another one of its important cities is Calama. The region's main economic activity is copper mining in its giant inland porphyry copper systems. Antofagasta's climate is extremely arid, albeit somewhat milder near the coast. Nearly all of the region is devoid of vegetation, except close to the Loa River and at oases such as San Pedro de Atacama. Much of the inland is covered by salt flats, tephra and lava flows, and the coast exhibits prominent cliffs. The region was sparsely populated by indigenous Changos and Atacameños until massive Chilean immigration in conjunction with a saltpeter ...

Llullaillaco
Llullaillaco () is a dormant stratovolcano at the border of Argentina (Salta Province) and Chile (Antofagasta Region). It lies in the Puna de Atacama, a region of tall volcanic peaks on a high plateau close to the Atacama Desert, one of the driest places in the world. It is the second highest active volcano in the world after Ojos del Salado. Llullaillaco formed during two different phases in the Pleistocene-Holocene out of dacitic lava flows. The oldest rocks are about 1.5 million years old. About 150,000 years ago, the volcano's southeastern flank collapsed, generating a debris avalanche that reached as far as from the summit. The youngest dated rocks were erupted 5,600 ± 250 years ago in the summit region, but there are reports of activity from the 19th century. The mountain's first recorded climb was in 1950, but traces of earlier climbs and a number of archaeological sites were found on the mountain and at its feet; Llullaillaco marks the highest archaeological site in ...

Protected Areas Of Antofagasta Region
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Vicuña
The vicuña (''Lama vicugna'') or vicuna (both , very rarely spelled ''vicugna'', its former genus name) is one of the two wild South American camelids, which live in the high alpine areas of the Andes, the other being the guanaco, which lives at lower elevations. Vicuñas are relatives of the llama, and are now believed to be the wild ancestor of domesticated alpacas, which are raised for their coats. Vicuñas produce small amounts of extremely fine wool, which is very expensive because the animal can only be shorn every three years and has to be caught from the wild. When knitted together, the product of the vicuña's wool is very soft and warm. The Inca valued vicuñas highly for their wool, and it was against the law for anyone but royalty to wear vicuña garments; today, the vicuña is the national animal of Peru and appears on the Peruvian coat of arms. Both under the rule of the Inca and today, vicuñas have been protected by law, but they were heavily hunted in the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BioScience

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Andean Dry Puna
The Central Andean dry puna (NT1001) is an ecoregion in the Montane grasslands and shrublands biome, located in the Andean high plateau, in South America. It is a part of the Puna grassland. Setting This ecoregion occupies the southwestern portion of the Altiplano and is located east of the Atacama Desert. Salt flats, locally known as ''Salares'', are a characteristic feature of this ecoregion. Among the largest salares are Coipasa, Uyuni, Atacama, and Arizaro. Other major geographical features are the lakes Poopó and Coipasa, and the many volcanoes that tower over the altiplano, including Parinacota, Nevado Sajama, Tata Sabaya, Ollagüe, Licancabur, Lascar (volcano), Lascar, Aracar, Socompa and Llullaillaco. In addition, numerous and colorful small lakes and ponds dot this region. There are seasonal as well as permanent, and have different degrees of salinity.

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...
