Logging in public and private forests in eastern Amazonia
Forest logging, public forest, forest control, management plan.
The objective is to evaluate logging in public and private forests through the volume actually logged and number of trees logged from timber management plans and managed forest species. We analyzed 68 licensed timber management plans through official electronic forest product control systems located in public (forest concessions) and private native forests in the state of Pará, eastern Amazonia, Brazil. The PMFS were categorized into federal, state, and private public forests from a single UPA and with more than one UPA. The PMFS were randomly selected, with minimum authorized forest area and volume of 500ha and 20 thousand m3, respectively. Data were obtained from the official forest control systems, federal (Document of Forest Origin - DOF / IBAMA / MMA) and state (System of Commercialization of Forest Products - SISFLORA / SEMAS / PA) used in the licensing and management of management plans. We obtained the actual harvested volume and the number of harvested trees from timber management plans and managed forest species calculated through a simple relationship between authorized volume and harvested volume, as well as the number of trees cleared and harvested. T-test will be applied to check for differences between treatments (logging yield index and number of trees logged) between management plans and between forest species using IBM SPSS Statistics, version 20.
