The objective of this paper was to evaluate density of planting, of mortality and annual periodic increment (API) of growth in diameter and height of species used in reforestation in areas of forest restoration after mining in conservation units in Amazonia. It was also analyzed the soil management practices in plantation areas. The monitoring covered a period of 13 years (1996-2009), at the National Forest Saracá Taquera, in Porto Trombetas, Pará State, Brazil. The species were distributed in classes of mortality. We analyzed the size and the ecological suitability, based on mortality and growth increments (diameter and height) of the species in the artificial ecosystem restored. The annual periodic increment of diameter considering the studied species allowed the following classification: excellent (7 species), high (33), low (20) and very low (9) and similarly, the grow of tree height it was found: excellent (9 species), superior (20), low (31) and very low (9). The ecological aptitude of 69 species in the study area, based on mortality and the increments in diameter and height, allowed the identification of the following groups of species aptitude: excellent (3), good (16), regular (25), low (21); improper (20) and inept (5). The use of soil practices during the activities of restoration should be reviewed due to strong evidence of mortality and growing of planted trees being influenced by soil storage time, the amount of top soil spread superficially, the acidity and fertility of soil and the top soil depth and the distance of transport to the target areas.
