Quantifying diameter distributions in seasonally dry tropical forest in Bahia, Brazil

This study aims to investigate the diametric structure of a seasonally dry tropical forest in Bahia and select best functions for stand species greater importance. Two subsets were selected fitting validation from pre- post-selective harvest inventories. Normal, Log-normal tested; Gamma, Weibull 2P, 3P. The fits using Kolmogorov-Smirnov test Akaike information criterion. Negative exponential curves positive skewness described diameter distribution. behavior was observed with highest IV stand. function describes Commiphora leptophioeeos, Manihot catingae, Pataggonula bahiensis. It is recommended individually describe structures Aspidosperma pyrifolium, Pseudobombax simplicifolium, population by 3P function. 2P did not present feasible predictions frequencies classes all analyzed cases.
