|The object of this survey was to analyze the growth and vigor of arboreal and shrub species planted in a reservoir shore of the Camargos Hydroeletric Plant, in the state of Minas Gerais, and to verify the processes of natural regeneration in function of the reservoir distance and along the planted area. At 150 months, in the arboreal species inventory, all the planted and the natural regenerations with diameter at breast height ≥ 5 cm were measured. Grades (1.0 to 5.0) were attributed for the evaluation of the tree vigor. For the natural regeneration survey, four transects were demarcated and three 1 x 15 m plots were established in each transect, following the slope. Results showed that some of the pioneer species displayed senescence signs after 13 years of planting. In the natural regeneration, 55 species of 27 families were identified. Species of the Asteraceae family predominated in the more disturbed areas, because they are adapted to these conditions. There was predominance in zoochoric dispersion among the regenerating species. The greater regeneration density was found near the reservoir, whereas the bigger diversity and average height were found in the opposite side of the planted area.
