Earthmounds fields are flat floodplain, which contain small elevations (morrotes) scattered in the landscape. These earthmounds have different soil and vegetation from the surrounding area, since it does not overflow during the rainy season. It is expected that the size (m²) and volume (m³) of the earthmounds exert influence on the floristic composition and plant community structure. Thus, the aim of this study was analyze the floristic composition and community structure of trees and shrubs in earthmounds in the Pantanal of Poconé, MT, in order to answer two questions: (i) Is there a correlation between the area and volume of the earthmounds with richness and abundance of tree and shrub vegetation? (ii) Is there a correlation between the area and volume of the earthmounds with the basal area of trees and shrubs? Were plots used to delimit the area of earthmounds field to be studied. In each plot, we measured the area and volume of each earthmounds and conducted the floristic and phytosociological survey. We observed that the area and volume influenced the richness, abundance and basal area of the species.
