Caracterização da vegetação ciliar em rios temporários de uma região do Semiárido da Bahia, Brasil

Abstract

(Characterization of Riparian Forest Vegetation of temporary rivers at Semiarid Region of Bahia, Brazil).Riparian forests are greatly important for its ecosystem. They provide protection against water siltation, water quality, feeding, wildlife protection and they are still recognized as ecological corridors. This paper aims to describe the community structure, physiognomy and the floristic composition of riparian forests of temporary rivers at Milagres and Itatim, Bahia, to provide basic information for riparian forest protection, enrichment and recuperation programs. The phytosociological survey was based on quadrant method throughout transectsat river margins. The sampling included individuals with diameter at the base equal to or larger than 3 cm.The river Sebastião presented secondary vegetation in initial stage while Rio Ribeirão initial secondary stage medium, both areas had high concentrations of the species C. yco.
