The project was carried out in a flooded Gallery Forest, located in the Marileuza Farm, Uberlândia-MG, Brazil. It is an area of open savannas and the Gallery Forest is located in a little valley. The phytosociological survey was done in 62 plots of lOm x lOm along five parallel transects distant 50m one to another and extended from the edge of the forest until they reached the drainage line. All the alive trees with circunference at breast height (CBH) > 15 cm were numbered sequentially with alluminium signs. Their height were estimated visually. It was also calculated the dispersion index tested using the t test as well as confírmed by the Morisita Index, The floristic diversity was calculated using the Shannon end Wiener index (H’). In the survey, there were 2189 individuais, from 33 species and 21 botanical families. The six most important species represented 75,88% of the total IVL. Nevertheless they represented only 18% of the number of species. They were: Richeria grandis Vahl., Xylopia emarginata Mart., Protium heptaphyllum March; Calophyllum brasiliense Camb., Ferdinanduscí specioscí Pohl. e Tapirira giúanensis Aubl. The floristic diversity index was 2,275 nats./ indiv., which may be considered low when compared to those obtained for other forests in Brazil or even in other areas of Gallery Forests in the region. This is probably due to the constantly flooded environment. It was confírmed that the pattern of distribution for the five most important species has contagious.
