This study was conducted to understand the dynamics of naturally regenerated seedlings and saplings in 28 years after selective cutting at natural Korean pine-broadleaved forests in Mt. Changbal. The number of naturally regenerated tree species was 16 species in 28 years after selective cutting. The appearance rate of naturally regenerated tree species was 567 species and the early-successional tree species of Acer ukrunduense, Acer mono, Acer pseudosieboldianum, Prunus padus var. pubescens, and Maackia amurensis were found in the first 10 years after selective cutting. The seedlings and saplings of shade-tolerant tree species of Pinus koraiensis, Acer mandshuricum, and Ulmus laciniata appeared and the appearance rate was higher than 75% after 15 years while it showed little change from 19 years after selective cutting. The distribution density of seedlings and saplings of regenerated tree species in selective cutting area was 5,500-6,100 trees per hectare in the first 10 years, and it increased gradually along with the restoration of disturbed area and it could reach 7,500 trees per hectare after 15 years.
Key words: natural broad-leaved Korean pine forest, seedlings, saplings, appearance rate, stand dynamics, early successional stage
