SUMMARY:

Sustainable Forest Management Plans - PMFs with the purpose of producing wood in logs have the ability to include in their planning operations for the extraction of exploited trees, such as branches and frogs, which can be marketed as wooden products. Seeking to improve forest exploitation, the study sought to investigate how the extraction of wood residues is planned and proposing a planning of drag trails and courtyards with less impact and better operating performance indicators. The proposed planning was generated with heuristic method, integrating the same data and characteristics of the machinery that the managers were based, with spatial analysis techniques in a geographic information system (GIS). The model has virtually created a drag trail infrastructure network for the extraction of exploited trees, generating a vector that can be compared to the planning vector practiced. The study was conducted in a Work Unit (UT) belonging to a company that operates in sustainable forest management in the region of Southeast Para, Para, Brazil. The data used to investigate the planning were the Georeferenced Forest Census containing information on tree selection criteria and maps used in the planning and execution of cutting and drag operations of logs and residues in the field. The set of field maps were scanned and the roads, drag trails and vectorized courtyards in GIS environment, considering the heuristic technique of the lower cost path, a spatial analysis focused on optimizing the location of connecting and flow lines (trails of drag) at the shortest global distance. Using the forest census, the volume of residues from the exploited trees was estimated from statistical literature models and employed to generate marginal impact and operational yield indicators, which subsidized models comparison. Also calculated with geoprocessing tools the length and distance of residues to the drag trails of the two planning models using falling information and height of the stem. Based on a virtual random sampling (GIS environment) with 1HA installments. In the installments were extracted the volume values of residues, the distance between the trees and the trails, the length and area of the drag trails of the two georeferenced planning models in GIS. With this data, the variables of trails (m/ha), trail productivity (m/m³) and trail impact (m²/ha) were compared by the T test of averages with significance level α = 0.05.
