The paper presents the results on studies, which dealt with a determination of relationship between annual ring widths of wounded firs formed before and after bark stripping occurrence on the undamaged side of stem and their dependence on features and location of wounds on trunks. The injured fir trees came from ten sample plots established in the Forest Experimental Station in Krynica (Beskid Sądecki Mountains). Analyses were done on discs cut from damage fir stems at the middle of the wounds. It was found that only width of ring formed in the first year after bark stripping was smaller than before wound occurrence. Average annual ring widths from three and five year periods following damage were larger than before it in the same period lengths. The increase of annual ring width occurred in the case of larger relative width and surface of wounds.
