Résumé:
The research aimed to evaluate the floristic composition in degraded riparian area of Caatinga
in Serra Branca, Paraiba Semiarid. The sample area centered on the ciliary ecosystem of the
stream Lagoa da Serra (Area I) and also for understanding the evolution of successional
processes thereof have been associate to survey the riparian forest of a stream contributor (Area
II) and an ecosystem of Caatinga adjacent (Area III). The three areas were subdivided into nine
sections. The floristic survey 24 species were recorded, which are distributed in 11 families and
23 genera. The predominant component was the tree where there were 19 species. All species
were recorded in Area I, however, for the Area II were raised 15 species belonging to 14
families and seven genera and for the III area found 13 species defined in 12 families and six
genera. Floristic comparison of environments studied in other surveys indicated a greater
similarity with studies in riparian forests in Cariri, highlighting the geographical proximity and
the ciliary system as responses to this given factors. Therefore, the riparian vegetation of the
Serra da Lagoa stream showed a floristic composition with a reduced number of species
compared with other works in most conserved riparian environments, demonstrating the high
degree of human disturbance in the area and their susceptibility condition the resulting
degradation man's action.
