ENCINAS, José Imaña; ANTUNES SANTANA, Otacílio  and  RAINIER IMANA, Christian. Diametric structure in a tropical dry forest fragment in the Cerrado Eco-Museum region, Brazil.. Colomb. for. [online]. 2011, vol.14, n.1, pp.23-30. ISSN 0120-0739.

In a tropical dry forest area of the Brazilian central region, the DBH distribution of 742 trees ≥ 5 cm was analyzed in a 4000 m² area. Eighty three tree species were found, of which 25 species with more than 10 individuals were analyzed for this study. The frequency histograms were obtained through the Meyer and Gaussian equations. The DBH distribution of the population showed a negative exponential inverse J curve. Of the 25 species selected, 14 exhibited the same pattern. Eight species presented a tendency near the normal distribution while three species had an abnormal pattern. We concluded that the observed fragment is in a natural auto regenerative status.

Keywords : de Lliocourt quotient; Meyer and Gauss equations; Plot sampling.
