Abstract

Northern red oak (Quercus rubra L.) is an important introduced tree species in Hungary, particularly in the Nyírség region. This study investigates its diameter growth (DBH) in six forest subcompartments, with stand ages ranging from 20 to 71 years. 5- and 25-year diameter increments were calculated. The distribution of diameter and diameter increment values was also determined. The results show significant growth across all sites. For example, quadratic mean diameter (QMD) increased from 16.4 cm to 30.4 cm over 25 years in the forest subcompartment Encsencs 12A, and from 20.3 cm to 38.4 cm in Ófehértó 2A. Five-year DBH increments ranged from 1.8 cm (± 0.8) in older stands to 4.2 cm (± 0.5) in younger or middle-aged stands. The findings confirm Q. rubra's capacity for steady diameter growth in northeastern Hungary and contribute valuable growth data for future yield modelling and forest management strategies.
