Amazon Basin

Covering approximately 12’000,000 H., the major area of the Ecuadorian Amazon supports exuberant vegetation that is typical of humid tropical forests, its western limit is the Andes Mountain Range, Peru lies to the south and Colombia to the north.

Immense quantities of material flowing from the Andes have been washed down the rivers, forming strips of alluvial soils and terraces that are used for farming.

Temperature

The annual average temperature falls between 25 and 25,5 C. Between 300 and 400 cm. of rainfall are distributed more or less equally throughout the year, although December through February are the drier months.

Flora

The principal attraction of the hilly forest is, of course, the trees, some soaring higher than 46 m. Common species are cinnamon, silkcotton, jacaranda and several leguminous trees. The alluvial plains, located on the terraces of the principal rives, support great concentrations of palm trees.

Napo River

The principal Amazon artery for visitors is the Napo River, a major tributary of the main Amazon River. Its basin is 1400 Km. long and one to three miles wide. As a result of fluvial dynamics, the Napo’s 130 islands are covered by young forests, which provide refuge and nesting sites for a multitude of bird species, many of them migratory.

Ecosystem

The Amazons ecosystem, particularly its tropical rain forest, is considered to be one of the richest and most complex communities of plant and animal life in the world. The region is characterized by huge and diverse amounts of flora and fauna with extraordinary variations in their habitats and micro habitats.

In the jungles of the Upper Amazon 100 species of trees per acre have been recorded. In Central America, only up to 40 species per acre have been discovered. In the temperate forests of North America and Europa, rarely more than 20 different species exist per acre.

The Amazon’s rivers, lakes, streams and marshlands support over 600 species of fish and more than 250 species of amphibians and reptiles. The lagoons of the Napo and Aguarico River basins are home to colonies of two species of caymans that grow to over 13 feet in length.

Conservation

Ecuador’s extensive national park system, scientific station and protected areas cover nearly a 7.5 million acres. To preserve areas, Ecuador has created the Yasuni National Park Biosphere Reserve8, the Limoncocha Ecological Reserve9, the Cuyabeno Wildlife Reserve10 and others. The Napo and Aguarico River basins offer multiple possibilities for you to enjoy the ecosystem complexes, alluvial plains, swamps and flooded areas all of which are inhabited by a variety of species. The Yuturi, Yasuni, Tiputini, Tivacuno and Cononaco rivers are completely surrounded by virgin forest.
