    Opis:
    The secondary invasion of Prunus serotina in the forest ecosystems is currently a serious problem, both in ecological and economical terms. The article presents how the intensity of the regeneration of this kenophyte depends on the type of coniferous forest community, in which it takes place. The effect of the herb and moss layers and of their attributes on the abundance of black cherry saplings is discussed.

    ecological indicator value
    Opis:
    The paper discusses the impact of clear−cutting and artificial regeneration on species composition of the fresh coniferous Vaccinio vitis−idaeae – Pinetum association Sokoł. 1981. The studies were conducted in the maturing artificially established stands (of 55−77 years) and 150−180 year−old natural old−growth stands in the Polish and Belarusian part of the Białowieża Primeval Forest. No quantitative and qualitative differences were found in species composition and structure between the two groups of stands. The lack of significant differences between the two development stages was ascertained using ecological indicator values. In the maturing stands the non−forest species were not found, and all species (so−called euphytes??), characteristic of the Vaccinio vitis−idaeae – Pinetum association, were already present there. This means that the use of a clear cutting system emulating the catastrophic natural disturbance pattern of forest dynamics in this association did not entail permanent changes in the ground vegetation.

    Opis:
    Fires that are one of the most classic disturbance of plant communities have had a great impact on the development of Scots pine communities. Restoration of vegetation disturbed by fire in this type of community starts almost immediately after disturbance. The intensity of fire significantly influences the future composition of vascular plant species and also the rate of change. The aim of the study was to describe the effect of intensity of the surface fire on the forest floor vegetation response and to preliminary attempt to characterize the syndynamic processes occurring after the disturbance. The research was conducted in Scots pine forest Peucedano−Pinetum in the Kampinoski National Park (central Poland). We established 45 permanent study plots, including 17 not burnt (control) and 28 burnt ones. Each plot covered area of 100 m². On each plot at first we separated the areas which were not burnt, surface burnt and characterized by complete burnout of the organic horizon of the soil. Than we measured the thickness of this horizon. Additionally the volume of organic matter burnt within each plot was calculated. Vegetation was sampled using Londo scale in the year of fire (2015) and the year after (2016). We used DCA ordination and UPGMA classification methods. Recorded species were divided into forest and non−forest groups and additionally for trees and shrubs, and the others, containing dwarf shrub, herb, bryophyte and lichen species. The linear regression method was used to estimate the relationship between measured parameters, vegetation change and changes in the species richness of distinguished groups. Two processes of vegetation reaction were observed. The first was classified as regeneration and occurred within surface burnt plots. Its characteristic feature included the higher increase in forest species richness than in case of non−forest species. The other process was defined as secondary succession alike. It occurred on plots with highest burnout of soil organic matter horizon. The increase of richness of non−forest species predominated within it. The change between two processes is smooth and depends on the participation of area with complete burnout of soil organic horizon within plot. The results show, that more than one process of recovery of community can occur in the same site and it depends especially on the proportion of soil organic horizon area burnout.

    Opis:
    The paper analyses the relationships between the microsite diversity of fresh coniferous forest and the number of Scots pine (Pinus sylvestris L.) seedlings from natural regeneration. The competition of forest floor vegetation (mainly of Vaccinium myrtillus) was found to be the decisive factor of pine regeneration. Lichens, especially Cladonia arbuscula and C. rangiferina, as well as mosses, e. g. broom moss (Dicranum scoparium) and pincushion moss (Leucobryum glaucum), can be regarded as the indicator species for the microsite suitable for pine regeneration.

    Opis:
    The main aim of the study was to determine changes in the species composition and structure of natural tree stands in the Białowieża Forest (BF), which occurred in the years 1975-2012, as well as to evaluate their trends, directions and rate. The study was carried out on 121 permanent research plots (50×50m), which represented the most important forest phytocenoses in BF, i.e. fresh pine-whortleberry forest Vaccinio vitis-idaeae-Pinetum Sokoł. 1980, fresh mixed spruce-reed grass forest Calamagrostio-Piceetum Soko³. 1968, oligotrophic form of hornbeam - bastard balm forest Melitti-Carpinetum Soko³. 1976, different forms of linden- hornbeam forest: Tilio-Carpinetum Tracz. 1962, alder-ash forest Fraxino-Alnetum W. Mat. 1952 and sub-boreal spruce forest on bog moss Sphagno girgenshonii- Piceetum Polak. 1962. On the plots selected, there was measured the diameter at breast height (DBH) of all trees, as well as every tree and shrub up to 1.3 m high was counted and described with reference to species. The measurements and observations were regularly repeated every 10-15 years. The results showed that over the last period of nearly 40 years, there has increased a share of common hornbeam Carpinus betulus L. in the structure of forest stands in numerous BF associations. This tree species has expanded into different forest habitats including poor, medium fertile and wetland sites. The results obtained indicate a trend towards formation of linden-hornbeam forests in BF phytocenoses. The most evident changes were recorded in hornbeam - bastard balm forest. In natural conditions of the majority of forest associations analyzed, there prevailed hornbeam trees in forest regeneration, except for the stands in fresh mixed pine forest and spruce forest on bog moss. In the latter two cases, hornbeam showed signs of its presence in the last observation period. Norway spruce (Picea abies L.) retreated into oligotrophic forest associations. In the recent decades, spruce populations have been dramatically reduced in the stands in mixed coniferous and different kinds of broadleaved forests. There have also decreased a share of light-demanding tree species, such as Scots pine (Pinus silvestris L.), pedunculate oak (Quercus robur L.) and silver birch (Betula pendula L.) in BF tree stands, including their regeneration-layer. Especially, Scots pine regeneration has not been successful. In the short period of time (about 15 years) there has been observed rapid and outsized reduction of ash Fraxinus excelsior L. populations in natural conditions of alder-ash forests. All through the last 10-15 years, there has been also observed increased rate of change in stand species composition. The trend and rate of change in stand species composition point out to a possibility of human intervention towards stimulation of natural regeneration so as to preserve valuable populations of threatened tree species in the Białowieża Forest.

    In this paper the attempt has been made to determine the proportion of sapwood and heartwood in pruned and non−pruned stems of Scots pine growing in the fresh mixed coniferous forest. Research results have shown that the proportion of heartwood in pruned pine stems was higher than in non−pruned ones. This was particularly noticeable after 24 years from the treatment while after 51 years this regularity was less distinct.

    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.

    The main objective of this study was to demonstrate a relationship between the direction and effectiveness of impact of particular tree species on soil properties and the initial site fertility. The studies were conducted on two neighbouring experimental plots with different forest site types (fresh mixed coniferous forest – BMśw and fresh mixed deciduous forest – LMśw). The analysed species Norway spruce (Picea abies L. Karst.), European larch (Larix deciduas Mill.), Douglas fir (Pseudotsuga menziesii Franco) and penduculate oak (Quercus robur L.) were planted in three replications on 400 m2 plots. It was stated that: 1) the humification processes ongoing under the canopy of the analysed tree species are, to a large degree, determined by the type of forest site; 2) under the same tree species the content of calcium and nitrogen in the nitrate form was found to by markedly lower in the BMśw forest site; 3) in the BMśw forest site, the pH and electrolytic conductivity of the soil under the majority of the analysed tree species were lower; 4) the degrading impact of coniferous species on soil was noticeably stronger on the poorer BMśw forest site.

    Opis:
    The paper presents the effect of artificial regeneration of stands with pine on a clear−cut area on the species composition of Calamagrostio−Piceetum association of reed−bed – spruce mixed coniferous stands frequently occurring in the Wigry National Park. The studies were carried out in two groups of pine stands: the old−growth stand at the age of 130−150 years, possibly established by way of natural regeneration and young−growth stands established by planting pine on clear−cut areas. Using traditional methods of phytosociological analysis no significant qualitative differences were found between the herbaceous vegetation of the both stands.
