The Madeira-Tapajós moist forests (NT0135) is an ecoregion in the Amazon basin. It is part of the Amazon biome. The ecoregion extends southwest from the Amazon River between its large Madeira and Tapajós tributaries, and crosses the border into Bolivia. In the south it transitions into the cerrado biome of Mato Grosso. In the state of Rondônia it contains some of the most degraded land of the Amazon basin,
The Madeira-Tapajós moist forests cover an area of 71,975,769 hectares (177,856,000 acres). They stretch in a southwest direction through Brazil from the Amazon into northeast Bolivia. The ecoregion covers parts of the states of Amazonas, Rondônia and Mato Grosso in Brazil, and part of the Beni Department in Bolovia.
The ecoregion covers the interfluvial region between the Madeira River to the west and the Tapajós rivers to the east, two large tributaries of the Amazon to the north. Above the sources of the Tapajós the ecoregion extends south to the Guaporé River basin. The large rivers prevent the spread of flora and fauna. Thus the white-fronted capuchin (Cebus albifrons) and hairy saki (Pithecia hirsuta) are found west of the Tapajós, while the white-nosed saki (Chiropotes albinasus) is only found east of the river. In the south the bounds of the ecoregion are defined by distinct changes in vegetation, with the transition to Mato Grosso tropical dry forests in the southeast and to the Beni savanna and later the Chiquitano dry forests in the southeast.
