Avaliação do crescimento do estrato arbóreo de área degradada revegetada à margem do Rio Grande, na Usina Hidrelétrica de Camargos, MG

Abstract

The objective of this study was to analyze the growth of tree species planted in a topographic gradient in an area degraded for the construction of the dam of Camargos Hydroeletric plant, MG. At 155 months after planting, three transects following the slope, 15 m wide and variable length were allocated, subdivided in parcels of 12 x 15 m along the topographic gradient. Plants with diameter at breast height (DBH) ≥5 cm were identified and measured (DBH and height). We concluded that, generally, the pioneer species showed a faster growth rhythm in the first 58 months and the climax species in the period of 58 to 155 months. Plant growth was affected by soil compactation and the effect of the topography gradient.
