IUCN category VI (protected area with sustainable use of natural resources)
Sucumbíos Province, Putumayo Canton; Orellana Province, Aguarico Canton
The Cuyabeno Wildlife Reserve (Spanish: Reserva de Producción Faunística Cuyabeno) is the second largest reserve of the 45 national parks and protected areas in Ecuador. It is located in the Putumayo Canton in the Sucumbíos Province and in the Aguarico Canton in the Orellana Province. It was decreed on 26 July 1979 as part of the creation of the national protected areas system based on the recommendations of the FAO report on the "National Strategy on the Conservation of Outstanding Wild Areas of Ecuador".
From east to west, the elevation gently slopes from about 300 meters to slightly under 200 m above sea level and has an area of 603,380 ha (1,490,000 acres). The upper watershed being still close to the Andes, the weather seems slightly milder than more eastern parts of the Amazon, with temperatures a bit lower during the day and at night usually cooling to the low twenties (°C) or seventies (°F).
The Cuyabeno Wildlife Reserve is an important nature reserve in Amazonia with rather unique ecological characteristics. Located at the foothills of the Andes, it is different from any other Amazon protected area in the world. The area encompasses a poorly drained plain with a network of periodically inundated forests, lakes and creeks. Such conditions are rare so close to the Andes, where the drainage in the foothills prevents the development of swamps and lakes. Given its proximity to the mountains, combined with a slightly cooler and wetter climate it may be expected to have a partly different species composition than other areas in the upper Amazon watershed. As all protected areas in the Amazon region, the area has a high biodiversity, but possibly a bit lower than better drained protected areas like the neighbouring Yasuni National Park, which is considered the most diverse park in the world. However, such claims must be met with caution, as insufficient data of other areas exist to scientifically compare the diversity of areas. Moreover, to the incidental visiting tourist or even professional biologist such differences are irrelevant because all areas close to the Andes are incredibly rich in species.

There are eight major ecosystems in Cuyabeno:
- (1) seasonally flooded forests or swamps, traversed by sediment-poor black-water rivers with a vegetation dominated by Mauritia flexuosa palms;
- (2) forests flooded by sediment-rich rivers, or varzea (Pires and Prance, 1985);
- (3) semi-permanently inudated forests flooded by black-water rivers, or igapó (Pires and Prance, 1985) and dominated by macrolobium trees which are the homes to countless epiphytes, herons, blue and yellow macaws and huatzins;
- (4) well-drained forest located on small hills in the upper watershed and the areas between the semi-inundated planes, particularly up-stream from the park entrance at "the Cuayabeno Bridge";
- (5) "coffee-and-milk" coloured sediment-rich rivers, the largest being the Río Aguarico;
- (6) "black-water" sediment-poor rivers, like the tributaries to the Río Cuyabeno;
- (7) permanent lakes that rarely fall dry, primarily Zancudo Coche along the Río Aguarico;
- (8) semi-permanent lakes - the largest being the Cuyabeno Lake - that most of the years fall at least partly dry.
Black waters (both rivers and lakes) can turn sediment-laden during periods of high rainfall.
All large amazon mammals are present: the lowland tapirs, two species of deer, all Amazon cats, including jaguars and pumas, capibaras, two species of dolphins, manatees, both otter species, giant otter (Pteronura brasiliensis) and neotropical otter (Lutra longicaudis), etc. Monkeys are represented by 10 species, while rodents and bats are represented by dozens of species.
The current number of registered bird species is under debate, some claiming 530 species while others suggest that more than 580 species have been observed, but nobody is known to keep sound records. At the peak of the wet season, thousands of hectares of forest become inundated, forming an El Dorado for an estimated number 350 fish species, two species of caymen, boa constrictors and anacondas, while countless frogs and toads sing their never-ending concerts. Dolphins have been seen swimming deep in the inundated forest during high water, as they follow the fishes.
There are two lake areas in the park. The largest network of lakes is in the eastern part of the park, and can be conveniently reached from Lago Agrio over an asphalt road. The other lake network is located at the border with Peru, and requires some extensive travel. These latter areas have a different flora and fauna than the forests on the higher grounds in between these wetlands and at the upper watershed. While the inundated forests are relatively poor in species, the higher grounds are have some of the highest number of trees per hectare on earth. On one location in neighbouring Yasuní National Park, 307 species of trees/hectare were counted.
The river system covers the rivers Aguarico, San Miguel and Cuyabeno along with their tributaries. Amongst the Cuyabeno, there is a system of about 14 dark-water lakes. In the rainforest of the Amazon of Ecuador, it is difficult to speak of a rainy season, but a dryer season runs from somewhere mid-December to the end of the middle of March, but the beginning and the end of the dry season varies considerable. The climate corresponds to a wet tropical forest, with precipitation of about 3000 mm or 180 inches per year, and humidity ranging from 85% to 95%. The annual temperature oscillates around 25 °C or 77 °F.
The Sionas live in the area of the upper Cuyabeno lakes network and along the Tarapuy river, while the Cofans, and the Secoyas live on the banks of the two major bordering rivers, the Aguarico and the Putumayo River, both affluents of the Amazon. A few Siona, Secoya, and Cofan folk shamans are respected for to their botanical knowledge and use of natural medicins. Until the 1980s, these communities have mainly lived of fishing, farming and hunting. Since then, the life of the indigenous communities in the Cuyabeno Wildlife Reserve has changed due to improved access with roads built for oil exploitation and earnings from ecotourism.
