The Japurá-Solimões-Negro moist forests (NT0132) is an ecoregion of tropical moist broad leaf forest in the Amazon biome.
The Japurá-Solimoes-Negro moist forests ecoregion is named for the Japurá, Solimões, and Negro rivers. Almost all of the ecoregion is in the central northern part of the Brazilian Amazon basin, with a small portion in Colombia.. It has an area of 26,961,776 hectares (66,624,000 acres). Conservation units include the Jaú National Park and the Mamirauá Sustainable Development Reserve.
The ecoregion lies on the lowland plateau in the interfluvial between the Rio Negro and the Solimões River. In Colombia the region skirts the foothills of the Guiana Shield to the northwest, and contains the lower Vaupés River basin and the land south of the Guainía River, the name of the upper Rio Negro in Colombia. The region is then bounded by the Rio Negro along the border with Venezuela and into Brazil to its confluence with the Solimões at Manaus. The southern border is defined by the Japurá River from the border with Colombia to the point where it meets the Solimões at Tefé, then by the Solimões to the Rio Negro.
To the west the Japurá-Solimoes-Negro moist forests adjoin the Caqueta moist forests, and to the north the Negro-Branco moist forests. To the east it adjoins the Uatuma-Trombetas moist forests. To the south it adjoins the Monte Alegre várzea, the Purus várzea and the Solimões-Japurá moist forests. The ecoregion contains large areas of the distinct campinarana ecoregion, which has white sand soils that are periodically subject to shallow flooding, and hold broad-leaf meadows, dwarf shrubs and shrublands.
