    Opis:
    Presented studies were conducted in the territory of the Strzyżów Forest District, in English oak plantations established under the Programme for the Development of Rural Areas, 2004−2006. The aim of this study was to compare the density, height, and quality of oaks planted in autumn or spring and protected from deer damage with wire mesh fencing or chemical repellents. Obtained results allow to suggest that wire mesh fencing is a better method of protecting plantations from animal damage and has a significant impact on the density, height and quality of oaks. Positive effect of autumn planting on oak performance was noted only after the elimination of deer impact.

    Opis:
    This paper describes the variability of Scots pine (Pinus sylvestris L.) provenances in the IUFRO experiment located in Rogów (central Poland). The silvicultural quality and growth of 17 European provenances at the age of 28 years were examined, including height, diameter at breast height, standing volume, straightness of stem and health status. Populations from Poland (Spała, Miło−młyn, Rychtal), Germany (Betzhorn, Lampertheim), France (Haguenau) and Hungary (Pornóapáti) characterized by the best growth parameters. In contrast, pines from Northern (Russia, Sweden) and Southern (Turkey, Montenegro and Bosnia and Herzegovina) Europe were smaller and thinner and, as a result, with lower standing volume. The smallest differences of pine populations were found in tree height. The highest mean tree height (11.68 m) was reported for Rychtal (Poland) provenance, while the lowest (6.77 m) for Çatacik (Turkey). The overall mean tree height in the whole experiment was 9.83 m. Diameter at breast height (dbh) varied more than the tree height. The highest mean dbh (129.91 mm) was reported for Haguenau (France) provenance, while the lowest (72.85 mm) again for Çatacik (Turkey). The overall mean dbh for all provenances equaled 107.12 mm. The highest differences of pine populations were found in the standing volume. The highest standing volume (19.05 m3/ha) was obtained for Pornóapáti (Hungary) provenance, while the lowest (163.72 m3/ha) again for Çatacik (Turkey). In terms of silvicultural quality, the northern provenances were classified as the best ones because of high proportion of trees with straight stems. The largest share of tress with straight stems occurred in the population of Serebryanskoe from Russia (60.8%), while the smallest of Haguenau from France (6.9%). The populations from Southern Europe (Maočnica, Prusačka Rijeka and Çatacik) show poor adaptation to environmental conditions of central Poland.

    Opis:
    The paper presents the study on the height of 10−12−year−old pedunculate oak regeneration in clear−cut gaps in three fertility variants: mezotrophic of poorer productivity (fresh mixed coniferous forest – BMśw), mezotrophic of higher productivity (fresh mixed deciduous forest – LMśw) and eutrophic (fresh deciduous forest – Lśw). BMśw and LMśw were represented by two locations: Gostynin (G) and Parczew (P), while Lśw – by one: Czarna Białostocka (CzB). We analysed the variation of oak height in the patches along the north−south (N−S) and east−west (E−W) gap axes. In each location 3−5 gaps were selected and measurements taken on three transects along the N−S axis located in the western (W), central (C) and eastern (E) part. Significant differences in oak height were found along the N−S axis. Oaks in the BMśw and LMśw habitats in the south−central part, and those in the Lśw habitat in the centre−northern part of the patch were the highest. The height growth of oaks on sandy soils (BMśw, LMśw) was found to be limited by moisture deficit, while on loamy soils (Lśw) – by light deficiency. The differences in oak height along the E−W axis were smaller and less apparent, indicating a tendency towards the reduction of their height growth in the central part of the gap.

    Opis:
    In the paper, an assessment of tree population dynamics in the old−growth stands of the managed part of the Białowieża Forest is presented. Data from five permanent sample plots with a total size of 9.3 ha and six inventories that cover the period 1949−2006, were used. Depending on the dynamic status, determined on the basis of changes in a number of individuals per hectare, basal area and quadratic mean diameter, three major groups of tree species were distinguished: 1) an increasing group, containing only hornbeam and lime; 2) a stable group, involving alder and spruce and 3) a declining group consisting of oak, ash, maple, pine, birch, elm and aspen.

    Opis:
    Two fundamental demographic processes (tree recruitment and mortality) are analyzed for forest stands growing on permanent study plots located in strictly protected Scots pine−dominated, old−growth stands of Kampinos National Park (central Poland). The major implications of the observed demographic trends for the general shape of tree size distributions are determined, as well. During the past ca 30 years, in the stands sampled, there was a pronounced lack of balance between mortality and recruitment processes. Mortality rate was eight times higher than recruitment rate. Eventually, there was a net significant decline in population density, observed for all major tree species, including Scots pine, pedunculate oak, silver and downy birch, and black alder. As mortality processes affected mainly smaller trees, there was also a significant deterioration of the general demographic status of most important tree species. This effect was shown by the change of the overall shape of diameter distributions over the study period: from reverse J−shaped to flat curves running nearly parallel to X−axis. The values of recruitment rates were markedly lower, and the values of mortality rates – significantly higher, than analogous values characterizing comparable forests (e.g., those obtained for the natural stands of Białowieża National Park). Low recruitment rates, as obtained for Kampinos stands, suggest that presently, in the local, Scots pine−dominated, old−growth stands, the general conditions for forest regeneration and for maintaining a long−term demographic stability are unfavorable. Most probably, the regeneration of this type of forest has an episodic, ‘wave−like’ character and corresponds to the ‘catastrophic’ model, according to which the successful regeneration of current dominants (especially Scots pine, silver and downy birch, black alder) must be preceded by a stand−initiating (stand−replacing) disturbance, leading to total or partial, but heavy, destruction of the currently existing stand. At the moment, it would be difficult to predict, however, if and when such a disturbance will affect the stands under investigation. Thus, we predict that in the nearest future at least, the state of overall demographic unbalance will continue or even increase.

    Opis:
    The paper describes changes, which took place over the last 30 years in old−growth forest stands occupying two permanent research plots, established in the Kaliszki and Sieraków strict protection areas in the Kampinos National Park (central Poland). Both plots have a form of ecological transects. The Kaliszki plot is 20 m wide and 700 m long (1.40 ha), while the Sieraków plot (total area of 2.56 ha) consists of two parts: main (40×460 m) and side (40×180 m) transect. In the Kaliszki plot, the stand measurements were conducted in 1993, 2007, and 2017, while in the Sieraków plot – in 1989, 1994, 2006, and 2017. For every tree with breast height diameter (DBH) 5 cm, species identity, DBH and spatial coordinates were determined. Starting from the second census, all trees which had died (‘losses’), as well as trees which exceeded the DBH threshold (‘gains’) since the previous record were noted, as well. The major tree species occurring on sample plots are Scots pine (Pinus sylvestris), pedunculate oak (Quercus robur), silver and downy birch (Betula sp.), and black alder (Alnus glutinosa). During the study period, the overall tree density declined by ca. 50%. The diminishing trends occurred for all dominant tree species. In contrast to major, dominant tree species, the demographic status of a group of minor tree species (lime, hornbeam and maple) was much more stable. One may even speak about some expansion in this case. Particularly, hornbeam density increased rapidly in the period 2006−2017 in some areas of the main transect located in the Sieraków plot. The future studies will show if this tendency will be maintained and will include other regions of sample plots. Assuming a lack of significant disturbances, one may expect that the stands growing on research plots will rather slowly change in the nearest future. Most dynamics will have a quantitative and not qualitative character. One may anticipate, for example, a growing role of pedunculate oak at the expense of Scots pine, however, considering that the two species are rather long−living, they will probably for a long time keep their dominant roles in the stand canopies.
