This work is the foundation for the Continuous Forestry Inventory (FCI) system of The State of Amazonas, which can be used in the definition and implementation of public politics for sustainable forest management and climate change projects. There were made studies about timber and carbon stocks; forest dynamics of undisturbed areas that were experimentally and entrepreneurially managed; allometry for determining the volume of stocks; determination of dominant height from the inventory of fallen timber; and finally the determination of inventory costs of installation, measurement and monitoring of IFC. There were used data from forestry inventories in managed and unmanaged areas of the following sites: Embrapa, Mil Madeireira (logging company) , ST Manejo de Florestas Ltda (logging company) , Resex of Auati-Paraná, Resex of Jutai River, Resex of Baixo Juruá, Resex of Lago do Capanã Grande, Resex of Unini River, Flona do Pau Rosa and State Forest of Maués, and also the RDS from Juma. In each site, the fallen trees were used to develop local volume equations and to estimate the dominant height (Hdom). The Hdom were used to correct the biomass equation developed in the ZF-2 Experimental Site, in Manaus City. In the site at MIL Madeireira logging company, it was analyzed the dynamics of the managed forest, since 1995, in a business scale, for timber volume and carbon stock. The ZF-2 site was used as reference for carbon dynamics. The cost of one single sampling plot for FCI in The State of Amazonas were estimated in US$ 278,44 ± 19,10 (IC 95%). The average carbon stock of The State of Amazonas is 160,34 ± 11,25 t.ha-1 (IC 95%). The forests of ZF-2 site and of the local community of São José do Inambé (Resex do Auati-Paraná, Fonte Boa) presented positive carbon increments of 0,03 ± 0,47 t.ha-1 (IC 95%) and 0,91 ± 0,94 t.ha-1 (IC 95%), respectively. Eleven years after the first selective logging at MIL Madeireira the commercial volume stock were estimated in 129,3 ± 28 m3.ha-1 and the carbon stock was 153,6 ± 24,5 t. ha-1 (IC 95%), showing that the environmental services of the forest were recovered. The nonlinear equations were chosen to estimate the volume of wood from each site studied, with R² over 80% and Syx% below 10%. For planning purposes of forest inventory, the estimated cost for installation and measurement was R$ 554 ± 120.09 (95%) and for monitoring of R$ 452.19 ± 360.20 (95%). The study concludes that the State of Amazonas has a network of continuous forest inventory with reliable, repeatable and auditable methodology. |
