Studies were carried out during 1987–1997 in four stands situated in the lower mountain zone, and representing the association <i>Carici-Fagetum abietetosum</i> (sample plots Facimiech and Walusi&oacute;wka) and the community of a transitory character between <i>Dentario glandulosae-Fagetum</i> and <i>Carici-Fagetum</i> (sample plots Gr&oacute;dek and Przelecz Sosn&oacute;w). The greatest volume increment was found in a pure fir (<i>Abies alba</i>) stand of Facimiech (9.4 m<sup>3</sup>/ha/year, i.e. 1.4% of actual stand volume determined in 1997) being in the optimum stage, phase of aging and regeneration, and the smallest one stand of Gr&oacute;dek (5.3 m<sup>3</sup>/ha/year, i.e. 0.9% of actual stand volume) being in the growing up stage, phase of selection forest. The stand of Przelcz Sosn&oacute;w was characterized by the greatest mortality of trees (volume of loss, i.e. 13.5 m<sup>3</sup>/ha/year). In this stand of a transitory character between the growing up and optimum stages, due to rapid mortality of fir the break up of the stand took place, and in consequence the growing up stage, phase of a little diversified stratified structure was developed. Volume of recruitment was the greatest in the stand of Facimiech, i.e. 0.05 m<sup>3</sup>/ha/year. In three fir (<i>Abies alba</i>)-beech (<i>Fagus sylvatica<i>) stands the proportions of fir and beech in stand increment differed from their proportions in stand volume. The percentage of fir in volume increment was smaller, and that of beech greater, than their percentages in stand volume. Processes of increment and mortality of fir and beech pointed to a progressive process of changes taking place in stand species composition, expressed by the increase of beech and the decrease of fir. The knowledge about values of loss, recruitment, and increment, expressed by the number of trees and volume units, may be of help in determination of the amount of cut in productive and protective forests managed according to a close-to-nature silviculture.

The characteristics of two beech (Fagus sylvatica L.) stands are presented in this paper. One, the Tarnicki stand, situated in the Bieszczadzki National Park, represents the growing up stage and selection phase of a forest of primeval character. The other one, the Otryt stand, is situated in managed forests of the Lutowiska Forest District. In each stand two sample plots were established. The distribution of the number of trees in each sample plot agreed with de Liocourt sequence and Meyer curve. Both stands were characterized by the structure of many generations. The Otryt stand, with respective volumes of 238 and 324 m<sup>3</sup>/hain two sample plots, was characterized by a lack of large diameter trees and a high percent of trees of the smallest diameters, while the Tarnicki stand, with volumes of 442 and 517 m<sup>3</sup>/ha, was characterized by the presence of large diameter trees (d<sub>1.3</sub> &ge; 72 cm). The phase of the selection forest in the Tarnicki stand is of temporary character because, due to natural processes, a two-storied structure may develop there, and with time, a one-storied structure in the optimal stage. In the Otryt stand, representing a managed forest, the maintenance of the selection structure may be expected due to selection cuttings. It has to be acknowledged that managed stands of characteristics similar to those presented in this paper makes it possible to carry out selection cutting, especially in the protection zone surrounding the Bieszczadzki National Park.

In three investigated stands the highest increment (8.8 m3/ha per year, i.e. 1.5% of the actual stand volume, measured at the end of the control period) was reached by Jawornik I stand in the initial period of the growing up stage, and Tworylczyk stand in the advanced growing up stage (7.4 m3/ha per year, i.e. 1.2% of the actual stand volume). Jawornik II stand, in the optimum stage, the aging phase, had the lowest increment (3.9 m3/ha per year, i.e. 0.7% of the actual stand volume). The process of a natural volume loss was the most intensive in Tworylczyk stand (7.6 m3/ha per year), a little less intensive in Jawornik II stand (7.1 m3/ha per year), and the least intensive in Jawornik I stand (5.8 m3/ ha per year). The analysis of tree loss, recruitment, and increment, and the relations between these processes, can form the basis for a conclusion that stable stands developed in the Carpathian primeval beech forests in the years 1988–1998. Such steady processes can be used for the development of a stable, multifunctional model of the forest managed by the selection system, or the Swiss irregular shelterwood system in the Carpathian beech stands of a similar structure.

The objectives of this study are to determine a trend of the radial growth at breast height (b.h.) and to compare the radial growth of trees of younger and older generations in the XX century for fir (Abies alba Mill.), beech (Fagus sylvatica L.) and pine (Pinus sylvestris L.) in the Świętokrzyski National Park. In the investigated area fir, 41 to 200–300 years of age at breast height, gradually regenerated its radial growth after a very strong decline during 1971–1990, and most likely the process of vitality reduction and death of its stands of various age is slowly coming to an end. Pine showed a systematic decrease in the radial increment during 1885–1994, and there were no distinct symptoms indicating a change of this unfavourable trend. Beech showed no significant decrease in the radial increment during 1885–1994. In the Świętokrzyski National Park the differences in the radial growth between younger and older generations were noticeable only in the case of beech. The radial growth of trees of different ages was very similar in the case of fir and pine.

The investigations carried out in 1988 and 1998 on three permanent sample plots in stands of the East Carpathian beech forest (Dentario glandulosae-Fagetum) showed that in the growing up stage, the storeyed structure phase (Jawornik I stand), the stand volume increased from 547 m<sup>3</sup>/ha to 578 m<sup>3</sup>/ha while in the optimum stage, the ageing and regeneration phases (Jawornik II), it decreased from 631 m<sup>3</sup>/ha to 600 m<sup>3</sup>/ha, and in the growing up stage, the storeyed structure phase (Tworylczyk), from 611 m<sup>3</sup>/ha to 610 m<sup>3</sup>/ha. In all three stands beech dominated in the upgrowth. During the 10-year period the volume of dead trees (standing and lying ones) increased in Jawornik II and Tworylczyk stands while in Jawornik I stand it decreased. The beech stands of the Bieszczady Mountains have a largely differentiated structure, from one-storey structure in the optimum stage, the ageing phase to many-storeyed structure in the growing up stage. This creates an opportunity for forming the complex stand structure, also the selection forest structure, in managed beech forests of the Carpathians.
