Diversity and Structure of the Gama Gallery Forest in Central Brazil in 2009

Abstract

The objective of this study was to evaluate the diversity and structure of the tree community of the Gama gallery forest, in the Federal District, in 2009. A total of 151 permanent plots of 10×20 m were allocated continually along ten lines perpendicular to the watercourse. All individuals with diameter at breast height (DBH) equal or greater than 10 cm were tagged and measured. In total, 114 species in 52 families and 96 genera were identified. The density was 643 ind.ha^-1, the basal area was 31.52 m².ha^-1 and 13 species were frequently at least in 25% of the plots. The Shannon index was 3.91 nats.ind^-1 and the Pielou index was 82%, expressing the good conservation condition and the high diversity of the vegetation. The diameter distribution curve showed an "inverted J" pattern.
