The study describes an experiment with the Swiss irregular sheltherwood system. A 40-year period of research and development allows to regard it as a new method which clearly bridges the gap between the Swiss irregular sheltherwood system and the selection cutting system. A new classification was proposed: — an irregular sheltherwood and selection cutting system.

The objectives of this study was to describe the size and position of wounds on European Silver Fir (Abies alba Mill.) and to analyse their impact on selected morphological features of crown. The studies were carried out in 10 sample plots in stands of Fir, located in the Forest Experimental Station in Krynica (Beskid Sądecki Mts.). Precise wound measurements were made and such features as growth tendency, vitality, absolute and relative crown length were determined. Wound size was characterized by mean relative width (60%), length (36% of wounds were shorter than 30 cm), and the surface area of the unhealed part of the wound (mean area ranged between 20 and 80 cm2). The most vulnerable section of the trunk to bark damage was found to be between 30 and 210 cm above ground level. The potential height of damage can be significantly limited by low growing branches. When damage intensity of the Fir Tree was >40% of trunk circumference and >30% of trunk surface, the tree was unable to reach the highest value of vitality index.
