Crescimento de uma floresta estacional semidecídua secundária sob manejo em relação a fatores ambientais, em Pirenópolis, Goiás

Resumo

In this study, we evaluated the growth of tree species in a seasonal semideciduous secondary forest in Pirenópolis, Goiás, Brazil, and its relationship with environmental factors using the Canonical Correspondence Analysis (CCA). We used a randomized block design with four silvicultural treatments. After four years, we evaluated the diameter increment of the species according to the slope and canopy openness in each treatment. The results showed that the diameter of the trees species studied increased differently depending on the silvicultural treatments and, in general, the treatments stimulated the diameter growth of the species, not rejecting the hypothesis tested. A great part of the species had higher diameter increment associated with lower shading, corresponding to the plots that underwent silvicultural treatments. We suggest further studies on the different populations separately, so that the technical management of seasonal forests can be improved and spread as a strategy to conserve these highly endangered environments, which are very important in the national timber market due to the presence of many species with high-value timber that have been explored intensively in natural environments.
