Levantamento florístico em áreas ciliares de caatinga: subsídios para a sustentabilidade dos ecossistemas ribeirinhos no semiárido paraibano.

Abstract

The work aimed at to evaluate the floristic in ciliary areas of Caatinga, subsidizing in that way the establishment of mechanisms of conservation and recovery degraded area in the paraibano Semiarid. The floristic survey was carried through non-systematic botanical collections and it embraced the present riverine areas along the streams of Umburana (7°45'15.3'' S and 36°58'01.6'' W; altitude 571 m) and Pedra Comprida (7°39'19.7" S and 36°53'04.9" W; altitude 524 m). In the floristic survey registered a total of 69 species, of the which 57 happened in the areas of the stream of Umburana and 39 in the Pedra Comprida. The predominant component in the two areas was the arboreal where they happened 45 species, being the shrub with 24 species. The families present in higher number of species and genuses were Fabaceae and Euphorbiaceae. In general, were present in the two areas ciliary 27 species. Were exclusive of the stream of Umburana 30 species and of the stream Pedra Comprida 12. Therefore, the data present important contributions inside for the integrated administration of the riverine areas and the sustainability of the natural resources of a perspective of regional development.
