The gallery forest and other unequal vegetal areas of semiarid suffered the antropized influence but this first kind of vegetation has been less studied. The floristic composition and phytosociological study of the woody representatives in the riparian forest of the Bodocongo River, semi-arid of the Paraiba State, it was studied through of the insertion of four transects perpendicularly to the water body in and each transect were plotted three parcels with 10x20 m. It was used Mata Nativa II program to calculate phytosociological parameters. The analyzed vegetation was represented by 357 individuals belonged to 16 genera and 7 families. The species that presented the most number of individuals were: Prosopis juliflora (221), Croton sonderianus (52), Pithecellobium dulce (20) and Ziziphus joazeiro (14). Prosopis juliflora occurred in all studied areas demonstrating its aggressive characteristic and also showing the susceptibility of areas that passed by human influence to invader areas. The highest importance value of quantity of species (VI) was Prosopis juliflora (49.22%), allowed for Ziziphus joazeiro, Croton sonderianus and Pithecellobium dulce. It was demonstrated that the bordering forest of Bodocongo River hasn’t contain an expressive floristic composition that it is related probably to the influence and degradation resulting from human action.
