Looking carefully the subtle traces of time in the Amazonian landscape, we will see major rivers shaping their courses and rainforests expanding and contracting due to climate changes and evolutionary processes of the major ecosystems that defined, for ever, the largest river of the earth.
All these factors, combined with other less obvious, collaborated on the formation of new species. In simpler words, the Amazon basin is like a big house with room for evolution and unlimited entry to new guests. The key of this eco-house are the flowering plants and the door they open is the greatest manifestation of tropical diversity on our planet.
From a biogeographically point, the Amazon region can be divided into four major regions: the Andean slopes, the Amazon plains, the Brazilian massif and the Guyanas massif. The major tributaries of the Amazon, whose sources are originated in the Andes, are the Madre de Dios, the Purus, the Kuría and the Huallaga.
PILCOPATA
This is a not navigable river that is why gives special chance of descending it with rubber boats, here a pleasant and quite rafting (class II and II) in crystalline waters make us enjoy the nature with some adventure.
ALTO MADRE DE DIOS
The Madre de Dios River, homonymous to the Peruvian region also called “Madre de Dios” it runs through, then becomes the Beni River in Bolivia and then turns northward into Brazil, where it is called the Madeira River. The Madeira is a tributary to the Amazon River getting in there close to Manaus.
The Madre de Dios is an important waterway for the department of Madre de Dios, Along the length of the river there are several national parks and reserves, notably Tambopata-Candamo National Park, Manu National Park (also known as Manu Biosphere Reserve) and Bahuaja-Sonene Reserved Area.
The Madre de Dios serves as the largest watershed in the area, as part of the vast Amazon River watershed.
AMAZON RIVER
This really is the giant of the rivers, with its 6760 km. length it becomes the widest and longest of the planet, with 50 km wide from side to side in rainy season in Para do Brasil where the Amazon River ends in the Atlantic Ocean. At the Obido the river reached 300 meters deep.
The effects of freshwater discharged into the ocean felt its effects at 200 km seaward; the Amazon pours 220000 cubic meters of fresh water per second into the ocean. The Amazon River is formed by water draining from the Andes of Venezuela, Colombia, Ecuador, Peru and Bolivia, the Amazon basin includes Brazil and the Guyanas. The headwaters of this huge river can be found in the mountains of Peru, in the "Mismi” mountain, located in Arequipa.
