Peruvian Amazon Basin
Peruvian Amazonia ( es, Amazonía del Perú) is the area of the Amazon rainforest included within the country of Peru, from east of the Andes to the borders with Ecuador, Colombia, Brazil and Bolivia. This region comprises 60% of the country and is marked by a large degree of biodiversity. Peru has the second-largest portion of the Amazon rainforest after the Brazilian Amazon. Regions of Peru Extension Most Peruvian territory is covered by dense forests on the east side of the Andes, yet only 5% of Peruvians live in this area. More than 60% of Peruvian territory is covered by the Amazon rainforest, more than in any other country. According to the Research Institute of the Peruvian Amazon (''Instituto de Investigaciones de la Amazonía Peruana'', IIAP), the spatial delineation of the Peruvian Amazon is as follows: * Ecological criteria: 782,880.55 km² (60.91% of Peruvian territory and approximately 11.05% of the entire Amazon jungle). * Hydrographic criteria or basin c ...

Manú River
The Manú is a river in southeastern Peru. It runs down the eastern slopes of the Andes Mountains into the Amazon Basin. It runs through what is now protected as the Manú National Park, a vast Biosphere Reserve, home to arguably the highest concentration of biodiversity on Earth. Few people live along its length. Much of the park is off-limits to all but permitted scientists and the indigenous groups of Amazonian Indians, mostly of the Machiguenga tribe. The Manú is a tributary to the Madre de Dios River, which downriver joins the Madeira River, and ultimately the Amazon River. In the late 19th and early 20th centuries, this area of what was organized as the Madre de Dios region was exploited for the production of rubber during the rubber boom The Amazon rubber boom ( pt, Ciclo da borracha, ; es, Fiebre del caucho, , 1879 to 1912) was an important part of the economic and social history of Brazil and Amazonian regions of neighboring countries, being related to the extrac ...

Madre De Dios River
The Madre de Dios River () is a river shared by Bolivia and Peru which is homonymous to the Peruvian region it runs through. On Bolivian territory it receives the Beni River, close to the town of Riberalta, which later joins with the Mamore River to become the Madeira River after the confluence. The Madeira is a tributary to the Amazon River. The Madre de Dios is an important waterway for the department of Madre de Dios, particularly Puerto Maldonado, the largest town in the area, and the capital of the department. Mango farming and gold mining are among the many industries on its beaches. Other important industries the Madre de Dios provides are selective logging and farming, both of which are serious environmental problems. Along the length of the river there are several national parks and reserves, notably Tambopata-Candamo National Park, Manú National Park (also known as Manú Biosphere Reserve) and Bahuaja-Sonene National Park.
