We studied tree composition and biomass (AGB) of the Araguaia floodplain, Brazil.
The region is characterized by annual floodings and a pronounced dry season.
Forest canopy height decreased and mean wood density increased with flood level.
Species richness, basal area and AGB of trees were not dependent on flood level.
The low AGB of the studied forest is most likely a result of the strong dry season and limited nutrient availability.
