This study was conducted to understand damage effects of Roe Deer (Capreolus capreolus) on the seedlings of Evergreen Oak (Quercus acuta) with the cutting of main stems before planted at Jeju Experimental Forests. Six plots in size of 20 × 20 m had been setup from the middle to the end of March, 2007, and planting after cutting the main stems of seedlings had been conducted to increase survival rate of the seedlings, and we monitored experimental and control plots to know the damage effects of the deers. Experimental plots were designed at the width of 3 m fields after clear-cutting, and they was adjacent with the buffer zone in size of 2 m covered with vegetation covers. Seedlings were planted at interval of 1 x 1 m, they were at 8 rows and 20 lines per plot. Two rows among them had been treated as half cutting at main stems. Total 647 seedlings had been planted, 168 seedlings were belong to half cutting's plots and 479 were to control plots. As a result, half cutting did not increase the survival rate of seedlings, and it increases the ratio of deer damage. Damaged seedlings showed significantly the lower height than undamaged did. Therefore, it would indicate that planting the seedlings over 90 cm in height would decrease the damage from deer at study areas. And, we suggest the damage factors on Quercus acuta as apical bud grazing, bark rubbing, and leaf grazing, we made the flow chart to decide the damage factors in the field.
