This study was designed to evaluate basic tree characteristics of Quercus dalechampii and Quercus polycarpa and to find out differences between them. Total height, height of crown base and diameter at breast height were measured before tree felling. Cut stems were visually checked for heart rot on their basal parts. Diameters were measured on each stem in 1 meter long sections from the base to the point of life crown setting. Average values for both species were compared by t-test. The total height was proved to be statistically different; the height of crown base and diameter at breast height were quite similar for both species. Q. dalechampii had a larger stem diameter from the tree foot to the 3rd height meter, whereas the diameter of Q. polycarpa was superior from that height upwards. However, the most significant interspecies difference was found in a number of stems affected by wood-rot fungi as Q. polycarpa turned out to be less resistant than Q. dalechampii.
