Tropical forest are generally rich in species. However, monodominant forests have been found at some tropical sites. In monodominant forests the main species contain about 50% of the total number of individuals. Monodominant forests of Brosimum rubescens Taub. (Moraceae), were found in the transition zone between Cerrado (Savanna vegetation) and Amazonia rainforest. These are patchy and seen to occur along the Araguaia valley in the States of Mato Grosso, Goias, Tocantins and Para. The studied site (14o50'47" S and 52o08' 37" W) is in Eldorado Farm in Nova Xavantina-MT. The wood is used in fences, building and furniture. It is also used by the Xavante Indians to make their traditional weapon, the "borduna". The Xavants and the fauna eat Brosimum fruits. The sampling was systematic, a 6,000m2 (40x150m) area was located in the central portion of the forest. This area was divided in 60 plots of 10 x 10 m. Height and diameter were measured for all individuals over 5cm dbh. Vertical stratification was also registered. A total of 41 species were found in the forest. Shannon diversity index (H') was of 2.37 and Pielou's evenness index (J') was 0,63. These values are low when compared to mixed tropical forest but similar to those found in an amazonian monodominant forest. Average density was 1,066 trees/ha and IVI were Moraceae, Rubiaceae, Burseraceae, Hippocrateaceae and Leguminosae-Caesalpinioideae. The main species in IVI was Brosimum rubescens (123.74), Amaioua guianensis (32.25), Cheiloclinium cognatum (21.86), Tetragastris balsaminifera (19.43) and Protium pilosissimum (16.49). Brosimum alone contained 85,5% of the individuals over 30cm dbh, 80% of those over 20cm dbh, 57.07% of those over 10cm dbh and 35.47% of those over 5cm including lianas and dead trees. The forest is composed of three strata: upper, middle and lower-storey. The diameter distribution is unbalanced for the community and for the main species. The forest structure may change in the future with the reduction of the dominance of Brosimum. Light seem to play a major role in the establishment and development of Brosimum.
