STRUCTURE AND FLORISTIC OF THE CERRADO SENSU STRICTO IN WEST OF BAHIA

ABSTRACT

In this study it was characterized the structure and floristic of the cerradosensu stricto located in Jaborandi, a city of western Bahia State. All individuals were sampled based on diameter height (D_30cm ≥ 5cm) present in a sample area of two hectares comprising 20 plots of 1000 m² (20m x 50m). Individuals were found in total of 2054 (1027 ind.ha^-1), on a basal area of 8.24 m².ha^-1and 58 species belonging to 42 genera and 24 families. Fabaceae had the largest number of species (12), followed by Myrtaceae (8) and Vochysiaceae (5). The phytosociological descriptors evaluated, have shown a community characterized by the presence of a few dominant species, where most can be regarded as unusual and rare. The diametrical structure and height presented a balanced vegetation, predominantly composed by small individuals. Here, richness is relevant, as well as local diversity, which was estimated at 2.95 nats.ind^-1 by the Shannon-Wiener index.
