This work aimed to study the "paratudal", an arboreal savanna formation of the Pantanal de Miranda, Corumbá - MS. There is a predominance of Paspalum hydrophilum grass and Tabebuia aurea tree species. The "paratudal" presents a mean density of 363 individuals/ha, height average of 6.7 m and stem diameter of 16.7 cm. This vegetation formation in some regions of the Pantanal de Miranda could be a result of the soil characteristics, flooding, human factor, and association with arthropods that form wooded hills, whereupon the species can be established. This species must present physiological mechanisms that allow it to survive with high levels of calcium and magnesium; alternated months of drought and flood and changes in the soil pH.
