ResumoThe study was developed in order to analyze the phytosociology and diametric distribution in a cerrado fragment with 7.5 ha located in the south of Tocantins. Six plots of 20x10m (200 sq m) were allocated, which were sampled every shrub-tree individuals with Circumference at Breast Height (CBH) larger than 9.5 cm. 486 individuals were registred, of which 454 are alive and 32 dead, distributed in 53 species, 50 genera and 29 families. The six most important species were Psidium catteleyanum, Astronium fraxinifolium, Tapirira guianensis, Qualea multiflora, Qualea grandiflora and Byrsonima stipulacea, totalizing 34.67% of the total IVI. The average of the vegetation was for height 6.5 m and diameter of 7.6 cm, besides a basal area of 17,08 sq m.ha-1, 4076 individuals per ha and volume of 83,53m³.ha-1m³/ha. The diameter distribution of the fragment showed the typical pattern in a “reverse J-shaped”.
