Igapó is a term used in Brazil to describe seasonally flooded forests that occur along the blackwater rivers of the Amazon Basin. During the rainy season, rivers such as the Negro and Tapajós rise and inundate large areas of forest. The water is typically dark, acidic, and low in nutrients, which influences the structure and functioning of the ecosystem. Flooding can last from several weeks to months, after which the land re-emerges as waters recede.
The igapó supports a distinct assemblage of tree and shrub species adapted to prolonged inundation and nutrient-poor
Fauna in igapó is shaped by the annual flood pulse. The inundation creates feeding opportunities for fish
Relation to other floodplain forests: Igapó differs from várzea, the floodplain forest along whitewater rivers, which
