| Resumo: |
The 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”.
The study was developed with the objective to analyze the phytosociology and diametric structure in a cerrado sensu stricto (Brazilian savannah) fragment with 7.5 ha located in the southern of Tocantins State, Brazil. Six plots of 20 x 10 m (200 m2) were allocated, and every shrub-tree individuals with circumference at breast height (CBH) larger than 9.5 cm were sampled. 486 individuals were registered, of which 476 are alive and 10 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 height of the vegetation was 6.5 m and 7.6 cm for diameter, besides a basal area of 17.08 m2 ha-1, 4076 individuals per ha and volume of 83.53m3 ha-1. The diameter distribution of the fragment showed the typical pattern in inverted “J”.
