Peru Amazon Rainforest Geography

The lowland jungle (Selva Baja) is also known as Amazon rainforest or Amazon basin. This Eco region is the largest of Peru, holding almost 50% of the country’s territory, on average between 50 and 1000 meters above sea level. It has very hot weather with an average temperature of 28°C, combined with a high relative humidity and high yearly rainfall. Its soils are very heterogeneous but almost all have river origins, and due to high temperatures and high rainfall they are poor soils with few nutrients. The Peru Amazon Rainforest geography is clearly marked by  the powerful rivers such as the Apurimac, Mantaro, Amazon, Urubamba, Ucayali, Huallaga, Marañón, Putumayo, Yavarí, Napo, Pastaza, Madre de Dios, Manu, Purus, Yurua and rio Tigre, most of the rivers alimented by the water coming from the high Andes Mountains. The Apurimac River is the Amazon River’s greatest contributor.

More to the west, the lands start rising towards the Andes and the Amazon rainforest geography changes drastically to the highland jungle (in Spanish Selva Alta). This particular part of Peru is also called Andean jungle or la ceja de la selva (The eyebrow of the jungle). This Eco region extends into the eastern foothills of the Andes, between 1000 to 2500 m above sea level. The eastern slopes of the Andes are home to a great variety of fauna and flora due to the different altitudes and climates within the region. Temperatures are warm in the lowlands and colder in higher altitudes. There are many endemic fauna because of the isolation caused by the rugged terrain of this area.
