In this research, the growth and adaptation status of natural young people coming to the area at the end of the first year were investigated as a result of the natural rejuvenation studies made on the beech-stem maple trees (Acer trautvetteri Medw.) in Sakarya-Hendek region. According to the measurement results obtained from the natural regeneration area, the mean height growth ranged from 10.6 to 13.4 cm, the mean root collar diameters ranged from 1.2 to 1.6 mm and the number of natural juvenilities varied from 4.3 to 5.6 item/m2.
