RESUMO:

The Brazilian federal and state legislation (Pará) establishes a minimum diameter of 50 cm for all commercial species, which overestimate the growth of plant species and may be incompatible with the restoration capacity of the forest, risk sustainability management. In this sense, this project has the following objectives: to establish classification criteria of DMC for Madeiran species and commercial projects in the Tapajós National Forest; characterize the use of timber species and e-mails for commercialization; the growth stock of commercial species; Determination of the relationship between sapwood and commercial species; and correlated with the suggested DMC with market demand from timber companies in Santarém, Pará. Questionnaires will be applied with the contribution of the timber forests in the communities of Flandres Tapajós addressing the questions about the forests timber extracted / managed, being these products that are made from them, and their characteristics of DAP (diameter measured at 1.3 m from the soil) are species are used. For the forest trial, the measurements were recorded, the direction towards the DAP for one of the following size classes (CT): CT 1 (regeneration class) - 10 cm ≤ DAP <25 cm in the first 50 m of the plot (30 mx 50 m); CT 2 (stock class) - 25 cm ≤ DAP <50 cm in the first 100 m (30 m x 100 m); and CT 3 (harvest class) - DAP ≥ 50 cm throughout the plot (30 m x 250 m). Based on the data from the sample forest test, the number of trees / diameter classes with a 10 cm amplitude will be plotted for all 24 timber species commercialized by COOMFLONA, in order to obtain a diametric distribution for each of these species. The photographs are selected and divided into 0, 25, 50, 75 and 100% of the commercial quantity, totaling four logs, with the measurements of their lengths, cut by bark, with the core diameter and the bark thickness, being executed in the two ends of all. sections and measurements at each end. The Smalian method will be used for accurate logging of the logs. Why carpentry and woodworking producers are also interviewed in order to characterize as the most used species for a product manufacturing, the classification criteria for this function are essentially commercial (gauges) and the advantages and disadvantages of working with a species.
