Abstract
The objective of this study was to evaluate the restoration of a degraded area compared to a reference area, in a sensu stricto Cerrado region in the Canaan Farm located in the municipality of Porto Nacional, Tocantins state, Brazil. For the lifting of the phytosociology were enclosed five sample ranges in each area, adopting the method of rectangular parcels with dimensions of 20x50 m, sampling the woody plants measured 30 cm above the soil, with circumference of the stem (CAS)≥10 cm. The absolute and relative parameters of frequency, density, dominance and values of importance were calculated. In the two areas of study, a total of 1.340 individuals distributed in 23 families, and 51 species were sampled. The area in restoration was the plant formation with greater richness of species (46) and higher density (28.800 ind. ha-1). In this way, it is concluded that the area that has undergone anthropogenic disturbances in past decades is currently structurally similar to the reference area.
