Methodological Notes5 Methodological NotesThe Brazilian Association of Forest Plantation Producers (ABRAF) adopted the same methodological accuracy applied tothe previous editions in the preparation of this Yearbook. This was a necessary condition to make it a solid reference for the sector,using information from reliable sources or estimates from experts of the forest plantation sector in Brazil, by comparing informationand developing alternate methods to analyze global values, and presenting the results in a transparent manner.The strict accuracy of procedures and calculus applied to the consecutive editions of the Yearbook has driven to reviseevaluation methods of some indicators, with the corresponding explanatory notes for each case inserted in the correspondingchapters. These revisions lead to continuous improvement of indicators to well-process and disseminate information on theforest plantation sector.This Chapter presents a summary of the methodological procedures used for data compilation, tabulation, comparison,data analyses and evaluation.Due to difficulties in accessing primary data necessary for the preparation and update of this Yearbook, ABRAF relied onclose collaboration with several forest companies and institutions, which can be grouped as: (i) sectoral contacts: ABRAF memberand non-member companies, consulting companies related to the forest sector, and also experts and representatives of the forestsector, and independent consultants; (ii) institutional contacts: state secretaries and state agencies, foundations, researchinstitutes, universities, associations and unions of the forestry sector, and associations for forest reposition, among others.The methodologies used for data compilation and analysis of Base Year 2007 are presented as follow, according to themain topics of the 2008 Statistical Yearbook - Base Year 2007: forest plantation areas in Brazil; protected forest areas linked toforest plantations; roundwood production and consumption balance; Gross Forest Product Value (GFPV); tax collection; forestproducts trade balance; and job generation.5.1 Forest Plantation Area in BrazilReference: Table 1.02 – Chapter 1The Yearbook used the following sources of information to estimate the area with forest plantations in Brazil:Chapter 578Information presented in the Statistical Yearbook 2007 – Base Year 2006 has been helpful, to a large extent, inupdating the current Yearbook.
