The wound healing rate (WHR) was investigated in 234 wounded trees in Iranian forests and was found to range from 6.4 to 24.0 mmyr -1 .Tree species, slope aspect, elevation, wound age, and wound type had significant effects on the WHR.The mean of the WHR in the Fraxinus excelsior (24 mmyr -1 ), Alnus subcordata (18.9 mmyr -1 ) and in the Fagus orientalis (17.9 mmyr -1 ) were significantly higher than in the Acer insigne (15.7 mmyr -1 ), Acer cappadocicum (14.6 mmyr -1 ), Carpinus betulus (13.7 mmyr -1 ), and Tilia begonifolia (6.4 mmyr -1 ).In addition, the mean of the WHR on northern slopes (17.5 mmyr -1 ) was significantly higher than on southern slopes.Moreover, the parameters that positively influenced tree growth showed a similar effect on the wound healing rate.The WHRs of 5-, 10-and 15-year-old wounds were 19.3, 16.9 and 10 mmyr -1 , respectively.The WHR increased the higher the wound from ground level.The WHR for horizontal wounds (18.4 mmyr -1 ) was significantly higher than for vertical wounds.The highest WHR was estimated in a stand with a canopy closure of 60-80%.The WHR decreased according to increasing wound width.Wounds affect future income, lowering the number of trees that potentially provide a higher quality of saw and veneer logs.
