The objective of this study was to find eco-revegetation measures recycling remnant root-stock of native species which comes to be disused. The monitoring plot was established in Nov.2001 at Honam University's affliated farm that is located in Wolya-Myeon, Hampyeong-Gun, Jeollanam-Do. The plots were monitored 2 times each in Oct.2002 and Sep.2003. Sprout and survival rate of the root-stock including the effect of trunk length, antiseptic treatment, planting season and number of planted were surveyed. The results of the study were as follows Ten tree species including Zelkova serrata among twenty tree species showed outstanding sprout and survival rate (over 90 percent). The growth rate was better in the longer trunk length root-stocks (35cm) than shorter ones (10cm). There was a difference in the size of the root ball when digging the root-stocks. It showed better condition when the root ball sizes were 3 times wide and 5 times deep of the root-stocks or 5 times wide and 5 times deep. Antiseptic treatment on the cuts of the trunk of root-stocks makes a difference in the growth rate. The survival rate of the root-stock showed highest value (100％) when it was transplanted in late autumn (November). And the next best survival rate was reached when it was in early or late spring (March and May)
