- Abstract
To contribute to the deeper knowledge of the southern Piaui vegetation, especially the areas of ecological tension, this study aimed to inventory and qualitatively assess the woody component of a Caatinga stretch in the municipality of Bom Jesus / PI, Brazil. To perform the survey plots were allocated 10 50x20 m (1000 m²) totaling 1 ha of sampled area, arranged contiguous way to minimize the possible edge effects area. They sampled the living woody individuals with diameter at breast height (DBH) ≥ 5 cm, regardless of height. In the survey we found 11 families, 25 genera and 27 species. Of these, those that stood out with the highest IVI values were. Cenostigma macrophyllum Tul., Combretum duarteanum Cambess., Erythroxylum laetevirens O.E.Schulz, Campomanesia pubescens (Mart. ex DC.) O. Berg and Licania rigida Benth. The diversity index Shannon-Wiener (H') was 2,7 nats.ind-1. For all purposes of comparison, it was observed that the study area is in good condition, not finding to direct exploration evidence, so little remains of forest fires, despite the proximity of the study area with the urban area the city of Bom Jesus do Piauí. The fragment is a vegetative ecotone, with predominance of species typical of the Caatinga.
