Abstract: In forest stands, is commonly subjected to logging and bark stripping injuries. Most mechanical wounds do not exceed 300 cm(2), but their pathological consequences are unclear. The aim of the study was to estimate the rate of wound occlusion and the probability of decay in stems in relation to initial wound size and wounding season. The study included forty-five stems with 1-, 2-, 3-, 4- and 5-cm-wide by 15-cm-long wounds (15-75 cm(2)), and eighty-three stems with 15-cm-wide by 20-cm-long wounds (300 cm(2)), made either in January or in August. After 19-21 years, each wound was assessed for occlusion rate and the presence of decay. All 1- to 2-cm-wide wounds were occluded, compared to 58-70% of the 3- to 4-cm-wide wounds, 25% of the 5-cm-wide wounds, and 0% of the 15-cm-wide wounds. On average, it took 3.6, 5.5, 10.4, 12.7 and 14.7 years to occlude wounds ranging in size from 1- to 5-cm-wide, respectively. After 21 years, the observed size of wounds comprising an initial area of 300 cm(2) ranged between 14 and 481 cm(2). Wounding season and stem DBH had no impact on wound healing. Wound decay incidence correlated positively with the initial width of injury ( = 0.925; < 0.05). All 1- to 2-cm-wide wounds lacked any decay, while the proportions of decay among 3-, 4-, 5- and 15-cm-wide wounds were 58.3, 50.0, 83.3 and 100%, respectively. Length of decay comprised 35-225 cm. Consequently, wounds on stems greater than 5 cm width are unlikely to be occluded and more prone to decay development
