The progress and intensity of the processes of regeneration, survival, and loss of trees in forests of a differentiated structure are presented in this paper A study concerned an area of 298.31 hectares of uneven-aged mountain forests of the Forest Experimental Station in Krynica managed by the shelterwood silvicultural system with the Swiss irregular shelterwood felling In the development of forests of a differentiated structure the increment was characterized by the highest intensity (8.83 m3/hectare/year), while the loss was less (4.14 m3/hectare/year), and the recruitment least (0.56 m3/hectare/year) intensive.
