The Napo moist forests (NT0142) is an ecoregion in the western Amazon rainforest of Colombia, Ecuador and Peru.
The Napo moist forests ecoregion covers part of the Amazon basin to the east of the Andes in the north of Peru, the east of Ecuador and the south of Colombia. It has an area of 25,174,684 hectares (62,208,000 acres). The ecoregion extends from the foothills of the Andes in the west almost to the city of Iquitos, Peru in the east, where the Napo and Solimões (Upper Amazon) rivers join.
In the extreme northwest the Napo moist forests ecoregion transitions into Cordillera Oriental montane forests to the west. Otherwise it transitions into Eastern Cordillera Real montane forests in the west. To the south it transitions into Ucayali moist forests, and into a broad belt of Iquitos várzea along the Marañón / Solimões river. To the east it transitions into Solimões-Japurá moist forests in the south and Caqueta moist forests in the north. The Napo moist forests contain areas of Iquitos várzea along rivers in the south and areas of Purus várzea along rivers in the north..
The terrain consists of floodplains and very low hills. To the west it is bounded by the foothills of the Andes. It slopes gently down from elevations of 300–400 metres (980–1,310 ft) in the west to elevations of 100 metres (330 ft) in the east. In the plains of the north the higher land rises no more than 10 metres (33 ft) above river level. Soils include older material from the Guiana Shield mixed with Quaternary sediments washed down from the Andes.
The Marañón River defines the southern boundary of the ecoregion. The Caguán River, a tributary of the Caquetá River defines the eastern boundary in Colombia. The Napo River, a tributary of the Solimões, defines the eastern boundary in Peru. Other important Amazon basin rivers that cross the ecoregion include the Morona, Pastaza, Tigre and Curaray, and the headwaters of the Caquetá and Putumayo.
