We assessed the species composition and community structure of herbaceous and tree/shrub strata in two agroforestry systems (AGP and SILV), traditional cropping system (TRAD0), areas under fallow for six (TRAD6) and nine (TRAD9) years and preserved Caatinga vegetation (MATA). We determined the absolute density and frequency of species, using plots. Individual trees/shrubs were separated into size classes of diameter. In the herbaceous stratum, the most frequent and abundant species were Alternanthera ficoidea in AGP, Amaranthus in SILV and TRAD0 and Commelina virginica in AGP, TRAD6, TRAD9 and MATA. The most frequent and abundant species in the tree/shrub stratum of AGP, MATA and SILV was Cordia oncocalyx. Mimosa caesalpiniifolia and Croton blachetianus occured at the greatest densities in TRAD6 and TRAD9, respectively. After fallow periods of six and nine years vegetation recovered floristic composition, although there was more individuals with smaller diameters when compared to MATA.Downloads
