The present results revealed that all tree species had a survival rate of more than 82% and no bad trees. (i) in Quan Son, the values of D0 and Hvn increase mostly in Chukrasia tabularis (6.85 mm and 62.51 cm), intermediate in Manglietia conifera (6.38 mm and 51.84 cm) and the lowest in Madhuca pasquieri (5.52 mm and 48.21 cm)
(ii) in Lang Chanh, the D0 and Hvn values were highest in Chukrasia tabularis (6.53 mm and 60.45 cm), followed by Manglietia conifera (6.09 mm and 50.66 cm) and lowest in Paramichelia baillonii (5.48 mm and 52.57 cm)
(iii) in Nhu Xuan, the values of D0 and Hvn were highest in Erythrophleum fordii Olive (6.93 mm and 65.45 cm), average in Lagerstroemiatomentsa Presl (5.48 mm and 52.57 cm) and lowest in Canarium album Raeusch (2.98 mm and 20.47 cm)
(iv) in Cam Thuy, the D0 and Hvn values were highest in Chukrasia tabularis (6.46 mm and 68.82 cm) and followed by Michelia mediocris Dandy (6.23 mm and 58.86 cm) and lowest in Erythrophleum fordii Olive (5.26 mm and 54.74 cm)
(v) in Thach Thanh, the values of D0 and Hvn were highest increase in Dracontomelum mangiferum (5.96 mm and 62.53 cm), intermediate in Michelia mediocris Dandy (5.66 mm and 56.74 cm) and lowest in Erythrophleum fordii Olive (4.08 mm and 42.26 cm)
(vi) in Nhu Thanh, the D0 and Hvn values were highest in Erythrophleum fordii Olive (7.28 mm and 66.24 cm) and then in Dracontomelum mangiferum (5.87 mm and 63.32 cm) and the lowest in Castanea sativa (3.43 mm and 22.48 cm). The results of initial assessment suggest that 11 plant species are growing relative stably, there are differences, but it can be observed that these are promising afforestation tree species for forest enrichment supplementary planting in the research site.
