The species composition of oaks and their associations at natural forests, and the effects of light intensities on their seedling growth were examined to understand their ecological characteristics. Also, reproduction and regeneration from seeds or sprouts were investigated at the field situations. All the study areas were dominated by Quercus species. However, species composition becomes diverse with decreasing latitude. High latitudinal areas in Kyunggido are characterized as oak forests, low latitudinal areas in Chullanamdo as mixed hardwood forests with oaks, and mid-latitudinal areas in Chungchongnamdo as pine-oak forests. Quercus mongolica showed highly positive associations with Q. variabilis, but did rather negative ones with Q. serrata. Q. serrata was the best in growth rate of height and dry weight under most of the light intensities. Much dry weights were distributed to roots at all the intensities for all the species. Covering or mulching over the seeded acorns helped better regeneration of oaks. Sprouting is useful for reproducing Q. mongolica and Q. dentata.
