The growth of 11 native broad-leaved tree species in a coniferous p lantation located in Zengcheng,Guangdong Province was studied. The result showed that the sap lings of four Fagaceae species (Castanopsis f issa, C.carlesii, C. eyrei, and Cyclobalanopsis bella) had vigorous growth in the p lantation during the first 5 years, whichwere excellent species in the ecological p lantations. The sap lings of Toona sinensis had rap id growth in the first 3years, but the growth declined in the fourth and fifth year. It had higher light requirement with its growing. It canbe used as reformed species in the low-density ecological p lantations. The sap lings of Tutcheria cham pionii wasshade-tolerant and showed good competition under the canopy. It can be used as the enrichment species for thereformation of secondary forests. The sap lings of Cinnam om um cam phora, L iquidam bar form osana, and M icheliam acclurei had relatively poor growth in the high-density ecological p lantations. The p lot investigation result indicatedthatmost understory species invading the p lantation were shade-tolerant and bird dispersed.
