The Cuyabeno Wildlife Reserve (Spanish: Reserva de Producción Faunística Cuyabeno) is a humid tropical rain forest protected zone in Ecuador. It is situated in the Putumayo Canton in the Sucumbíos Province and in the Aguarico Canton in the Orellana Province. It was founded on 26 July 1979. At an altitude of 200– 280 meters and an area of 6,033.8 square kilometres (2,329.7 sq mi), the Cuyabeno Reserve is an important conservation area of the complex Amazonian ecosystem. The reserve is a combination of rivers, lagoons and floated forests. The protected area is characterized by its high biodiversity and its interaction and cooperation between the species inhabiting the area. Its geomorphology is a consequence of the rivers carrying sediment and materials from the Andes, principally by Aguarico River, which is considered white water due to the sediment it drags raising water levels and therefore ensuring that the river is navigable all year round. It is considered to be one of the sites with the highest biodiversity in the world with the neighboring Yasuni National Park
