Evolution of the forest sector in the state of Tocantins, Brazil

Abstract

The aim was to know and to update the forest massif in Tocantins, in relation of planted area, and it was to provide data for the development of advertising campaigns, management techniques and application of technologies. The information about planted area, proprieties and planting were obtained through the collection of primary data (covering the entire state of Tocantins) and secondary data. With the data collected, the annual growth rate (AGR) was estimate for the new area with planting and of properties with these planting and this was done for the area accumulated with these plantations, too. The principal components analysis was done to understanding which indicators followed the forest sector evolution. Forestry in the state of Tocantins had shown in 2013 a accumulated planting area of the 105,989.11 ha (89% with Eucalyptus) with AGR about area planted with eucalyptus and other forest species of 40.8% and 8.81%, respectively. With principal components analysis, they can be see the positive relation between the recent growth on the forest sector in Tocantins with the increase of the use of primordial techniques for the success of the activity. Although the results obtained allow to verify the recent evolution of the forest sector in Tocantins, it was verified that it is in structuring stage because for the low use of silvicultural practices required for plantations of high performance, yet.
