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.

A new theory of processes occurring in forests of the varied structure of breast-high diameters is presented in the work. The two processes differentiated and defined are the survival and the decrement, the measurability of their intensity being determined. The identified processes were used in formulating the model of development of a forest management class characterized by a varied structure of breast-high diameters, in the form of the probability matrix of transitions. Such a matrix constains a complete information concerning the effect of the survival and decrement processes on the sustainability and balanced development of forests of the varied structure.
