Sobrevivência e crescimento inicial de espécies arbóreas nativas na restauração de nascentes no Sul de Minas Gerais

Abstract

This study aimed to quantify the survival and early growth of seven native tree species in ecological restoration of riparian forests in the vicinity of springs in the Southern region of Minas Gerais. The species used were Trema micrantha (Cannabaceae), Guazuma ulmifolia (Malvaceae), Lithraea molleoides (Anacardiaceae), Cedrela fissilis (Meliaceae), Aspidosperma parvifolium (Apocynaceae), Machaerium villosum (Fabaceae) and Handroanthus serratifolius (Bignoniaceae). The experiment was carried out in a completely randomized design, in a factorial 7 × 3 (species × locations). Eleven months after the plant it was found that, with the exception of C. fissilis and M. villosum, all species presented average rate of survival equal to or greater than 80%. The species that presented the lowest average growth in height after eleven months was C. fissilis (9.27 cm). With the exception this species, all demonstrated the ability to establish themselves in this type of environment and are recommended in projects of ecological restoration of riparian forests in the region.
