Resumen:
The structural and functional characteristics of riparian ecosystems are essential
for the conservation of fragments and recovery of degraded areas and the distribution of
species are elements bases to be known. The objective of this work was to study the
distribution of shrub and tree species in two riparian areas in Paraiba Cariri. The study was
conducted in two courses of water of intermittent regime in the municipality of Sumé-PB, that
is, in the stream of Umburana (7°45'15.3'' S and 36°58'01.6'' W; 571 m of altitude) and
stream Pedra Comprida (7°39'19.7" S and 36° 53' 04.9" W; 524 m of altitude). The study was
conducted through of hiking exploratory and processed unsystematically on the banks of both streams. The collection and identification of shrub and tree species was processed
monthly. The floristic lists were compared based on presence/absence of the taxon identified
to species level, in order to verify the similarity between taxonomic areas analyzed. Were
recorded 69 species in the two areas, of these, 27 were common to both. 30 species were
exclusive to the stream of Umburana and 12 to the stream of Pedra Comprida. The arboreal
component was predominant . 45 species were recorded in the arboreal component and 24
in the shrub. In both environments the most representative families were Fabaceae,
Euphorbiaceae, Anacardiaceae and Cactaceae. Therefore, the data contribute to the
integrated management of riparian areas and the sustainability of natural resources within a
regional development perspective.
