dc.description.abstractengThis research was carried out at Pinus massoniana Lamb. and Acacia auriculiformis Benth plantation sites of between nine to eleven years old in Luc Ngan Distric, Bac Giang Province, Vietnam. Its purpose is to contribute to the knowledge of the dynamics of site conditions beneath the plantation canopy and the growth of indigenous species in local species trials, and to propose silvicultural management options for the gradual transformation of forest plantations into close-to-nature forest. The research indicated that ten years after the establishment of the forest plantation on bare hill, site condition under plantation canopy including soil properties, temperature, humidity, and natural regeneration ability of indigenous species under canopy was significant and positive change. Moreover, the plantation canopy closure varying from 0.4 to 0.6 is the most suitable for the growth and development of indigenous tree species in the first three years after planting. In this study, four species consisting Canarium album, Erythrophleum fordii, Cinnamomum obtusifolium, and Michelia mediocris were selected for planting under plantation
