Diverse Vegetation of Bolivia

17.3S 66.1W

April 17th, 2013 Category: Salt Flats

Bolivia – April 16th, 2013

Bolivia has a huge degree of biodiversity, considered one of the greatest in the world; as well as several ecoregions with such ecological subunits as the Altiplano, tropical rainforests (including Amazon rainforest), dry valleys, and the Chiquitania, which is a tropical savanna. All of these feature enormous variations in altitude, from an elevation of 6,542 meters above sea level in Nevado Sajama, to nearly 70 meters along the Paraguay River.

Here, green vegetation can be seen northeast of the Andes Mountains, in Bolivia, in the tropical, forested portion of the country. Across the mountains, however, lies the arid, sparsely vegetated altiplano portion of the nation, which includes the bright white salt flats of the Salar de Uyuni.

Changing Water Levels in Lake Poopó, Bolivia

Bolivia – January 25th, 2013

Lake Poopó sits high in the Bolivian Andes, catching runoff from its larger neighbor to the north, Lake Titicaca. The runoff arrives by way of the Desaguadero River, visible as the muddy area at the north end of the lake.

Due to the very high elevation at which Lake Poopó is located (roughly 3,400 meters, or 11,000 feet above sea level), its very shallow depth (generally less than 3 meters, or 9 feet), and the dryness of the regional climate, small changes in precipitation in the surrounding basin have large impacts on the lake’s water levels and area. Changing water levels in Lake Poopó affect its idealness as a stop for migratory birds, including flamingoes.

Lakes in Argentine and Chilean Patagonia

Chile and Argentina – November 16th, 2012

Several lakes can be seen by the Andes Mountains and Chile-Argentina border in this image of Patagonia. The northernmost is known as Lake General Carrera (Chilean side) or Lake Buenos Aires (Argentine side). It has a surface of 1,850 km² of which 970 km² are in Chile and 880 km² in Argentina, making it the biggest lake in Chile, and the fourth largest in Argentina. The lake is of glacial origin and drains to the Pacific Ocean on the west through the Baker River.

Visible to its south, also dark blue in color, is known as Cochrane Lake in Chile and Pueyrredón Lake in Argentina. The Argentine portion of the lake has a surface of 150 km2, while the portion in Chile covers 175 km2. It is a glacier fed lake.

Continuing southward, three light blue lakes can be seen: Lake O’Higgins/San Martín (the former name is used in Chile, the latter in Argentina), Viedma Lake and Argentino Lake. All three are glacial lakes, and their milky color is due to rock flour suspended in their waters.

Fires in Bolivia and Paraguay

Bolivia and Paraguay – October 1st, 2012

Plumes of smoke from fires in Bolivia and Paraguay blow mostly towards the south and southeast, although those at the upper right are carried northeastward by the wind. There is also a general, smoky haze over the right side of the image, while the left side, near the Andes Mountains, is clearer.

Smoky Haze Over Brazil and Peru

Brazil and Peru – August 31st, 2012

Smoke from fires in Brazil and Bolivia blows westward and creates a haze over the rainforest near the right edge of this image. Some smoke can also be seen nestled along the Andes Mountains in Peru, on the left side of the image.
