Objective
To identify suitable thinning intensity of nurse trees for enhancing optimal growth of various native tree species planted in mixed plantation and to study effects of thinning intensity on the litter fall and nutrient return.

The plantations were established in 1997, 1998 and 2001 in Silvicutural Experiment Research Center, Doan Hung district, Phu Tho province. Acacia mangium was planted as a nurse tree for young native tree species such as Cinamomum iners, Canarium album, Lithocarpus fissus, Endospermum chinense, and Peltophorum tonkinensis. In this experiment, 3 years old, 6 years old, and 7 years old mixed plantations were selected for the experiment.Thinning density for 3 years old plantation are 0, 25, 50, and 75 %, and those for 6 and 7 years old plantations are 0, 50, 75, and 100 %.
