Abstract

This study was developed in the Union county, localized in center-north region of the Piaui State, and aim to determine the production of biomass and floristic composition of secondary forests with different ages after slash and burn agriculture (one, three and five years-old regeneration stages, with two replicates). For analysis of vegetation they were established 20 plots by each different age of fallow. Plots were used with areas of 25.0 m2 by shrub/tree and, within these, subplots with 2.0 m² were allocated for the herbaceous species. The results show that 100 species occur in the area, 42 shrubs and 58 herbaceous species; the secondary forest with one, three and five years present total biomass of 3.4; 6.0 and 6.7 ton ha-1 of total dry mass per hectare, respectively.
