Amazon Rainforest in Peru
The Amazon is an ecological region characterized by its dense and humid tropical forest, and by the intricate hydric system that has as axis the Amazon River, the largest and most extensive in the world. The Amazon River basin occupies approximately 7,350,621 km2, of which 68% belong to Brazil. Other countries present in the basin are Peru, with 13% of the total, Bolivia, with 11.2%, Colombia with 5.5%, Ecuador with 1.7%, Venezuela with 0.7% and Guyana with 0.1% .1.
The Amazon takes its name in Peru, at the confluence of the Ucayali and Maranon rivers, near the city of Nauta. The structural depression that forms between the two rivers is called UCAMARA and coincides almost in its entirety with the limits of the Pacaya Samiria National Reserve, one of the most biodiverse floodplains of the Peruvian Amazon.
The sediments carried by the Ucayali and Marañón rivers are so large that they fertilize the entire basin, from the Andes to the Atlantic. Rivers of Andean origin are known as “white water” rivers, due to the café-au-lait color of their waters. These rivers carry a greater amount of nutrients than those of crystalline or dark waters, known as “blackwater” rivers. All the nutrients that enrich the Amazonian rivers have their main origin in the Andes.
