Floresta Estacional: madeira para o produtor rural no Cerrado

Abstract

This study had as objective to characterize the flora from a forest fragment and to analyze the diametric structure of commercial species in a semidecidous forest fragment, in Pirenópolis – Goiás. The studied fragment has 8820 m² and was randomly sampled through 21 Prodan points, where diameters at breast height (DBH) were measured and total heights were estimated in each point. The forest showed a diametric distribution adjusted to negative exponential curve. The estimate for total individuals was 810, 19 trees ha-1 and the volume estimative was 147,95 m³ ha-1. The highest Importance Values (IV) were represented by Apuleia leiocarpa, Davilla elliptica, Virola sebifera, Protium heptaphyllum, Dipteryx alata, Inga cylindrica e Emmotum nitens, and the floristic richness was 46 species, the Shannon index was 3.25 and the equability was 0.91. The potential species and the ones that are already marketed were: Anadenanthera colubrina, Apuleia leiocarpa, Copaifera langsdorffii, Physocalymma scaberrimum, Platypodium elegans, Virola sebifera, e Chrysophyllum gonocarpum, representing 24,6% of arboreal density in the site. This study demonstrated that forest fragment is capable to be managed, however complementary studies are necessary.
