<br/><br/> <br/><br/>ABSTRACT<br/><br/>The state of Pará ranks second in Brazilian mineral production, where bauxite accounts for 84% of<br/>total mineral extraction, with negative impacts on the environment as a result. The determination<br/>of objectives and targets using environmental indicators as a tool to evaluate forest restoration<br/>processes is essential in the recovery of these exploited areas. This study aimed at evaluating the<br/>efficiency of forest restoration techniques by means of 13 qualitative and quantitative indicators<br/>for monitoring post-bauxite mining operations. Permanent plots were implanted in revegetated<br/>areas with the use of two techniques: planting of seedlings and stewarding of natural regeneration.<br/>It is concluded that the techniques are efficient for the recovery of forested area. However, natural<br/>regeneration showed greater efficiency for restoration for Density, Erosion and Exotic Species<br/>indicators. Still, natural regeneration should not be the sole option in the processes of ecosystem<br/>restoration, since planting proved to be more efficient for some indicators.<br/><br/>Keywords: mining, forest succession, topsoil.
