Mortality patterns ad changes of vegetation in newly formed gaps were investigated to examine the succession process of Pinus densiflora forest located at Mt. Worak. The main findings from this study were as follows: ⑴ The forest was dominated by P. densiflora and Quercus variabilis in the oversotry, while Q. mongolica, Q. serrata and Fraxinus sieboldiana in the mid-story. ⑵ In all study areas, the standing dead type was the most common factor influencing gap-forming mortality. ⑶ DBH analysis showed that Pinus densiflora community was replaced by Quercus variabilis community first, and then by quercus mongolica and quercus serrata community. ⑷ Seedlings of P. densiflora were discovered only at dry sites of the gap.
