    Opis:
    The authors describe the difference between canopy cover (proportion of the forest floor covered by the vertical projection of the tree crowns) and canopy closure (proportion of sky hemisphere obscured by vegetation when viewed from a single point) and the respective ground-based estimation techniques focused on two types of densiometer (GRS tube and spherical). The data collected in the field were used to analyse the relationship between forest canopy and natural regeneration in two subtypes of subalpine larch-spruce forests. The results indicate that in the first subtype characterized by a high fertility and a high canopy cover (around 62%), the level of natural regeneration is low (115 stems per hectare) and it is nearly exclusively composed by spruce [Picea abies (L.) Karst.]. For the second subtype characterized by a low fertility and a medium canopy cover (around 49%) the natural regeneration is rather dense (650 stems per hectare). At last the authors evidence a insignificant difference between the data of forest canopy collected by different ground-based estimation techniques (+0.7% using spherical densiometer compared to using GRS tube densiometer).

    Opis:
    The paper concerns the structure of natural regeneration in ash−alder riparian forests (Fraxino−Alnetum) colonized by beavers (Castor fiber) taking into account the substrate, on which it appears (soil and deadwood). Study was conducted in 2016 on twelve sampling plots located in the Orłówka valley in the Białowieża National Park (eastern Poland), where beavers settled around 2005. We counted natural regeneration occurring on the ground and on deadwood on each plot. Also we identified volume of deadwood, decay status and water cover. A decade after the occurrence of beaver ponds, the density of natural regeneration is 5575 saplings per hectare and the regeneration on deadwood is 28% of the total. Black alder is the dominant species. The regeneration occurring on the soil is richer in species and has a larger share of shrub species. In the case of regeneration on the deadwood, seedlings appear first on trees fallen before the flood. Over the time, the role of deadwood as a substrate for the development of regeneration increases and the role of fallen trees is the greater, the greater is the fraction (coverage) of the flooded areas. Studies show that the continuous occurrence of the deadwood accelerates habitat regeneration after a disturbance such as the occurrence of a beaver pond.

    Opis:
    Characteristic features of European woodland include both a reduction in natural forest areas and an increase in former agricultural areas occupied by secondary woodland. The management of these areas is challenging in terms of nature conservation, agricultural and forestry management and policy. The aim of our study was to reconstruct the history and to document the current tree stand structure for a secondary oak-beech woodland in Hungary. Towards the end of the 1800s, this area which was once almost completely occupied by a continuous forest, had been transformed into a wood-pasture. As a result of its gradual abandonment, the closed forest stand of the pasture increased from 10 to 52% between 1963 and 2005. The most characteristic feature of this woodland is the abundance of large trees. Globally, the number of large and ancient trees is rapidly diminishing. Therefore preserving and maintaining such areas, where large trees could live, is an essential management task.

    Opis:
    European beech (Fagus sylvatica L.) is a widely distributed forest tree species in central, southern and western Europe. In Poland it reaches the eastern limit of its natural range. The three forest stands selected for the analysis presented here are located in the Dukla Forest Inspectorate, southern Poland in the Beskid Niski Mountains. The measurement plots were rectangular, 0.35 ha each, established under homogenous conditions. The origin of all stands is natural and up to now they were thinned several times according to selective thinning method. The main tree species on each plot is European beech. In each stand (x, y) coordinates, the species, total heights of trees and their diameters at breast height were recorded. Total tree height, diameter, basal area and tree volume were considered as marks in statistical analysis. The aim of this paper is to find out the differences in the spatial autocorrelation of different tree marks as well as to explain the reasons for differences if they were observed. The empirical mark correlation functions indicated that there is a negative spatial correlation of all these marks in all three forest stands, i.e. trees close together tend to have smaller marks than the average in the stand. No significant spatial correlation was found for the tree heights. Diameter, basal area and volume show some correlation, but only in one stand a deviation test showed that the detected spatial correlation is significant. The mark variograms indicated that neighboring trees tended to have similar sizes.

    Opis:
    The study shows a high dynamics approximately five-year-old natural regeneration of silver birch (Betula pendula Roth) growing on the research plot located in the fertile mountain habitat in the middle of the lower montane forest zone in the Silesian Beskid Mountains (Beskid Śląski) compared to its co-occurring species. The dynamics is expressed as a significant annual increment in height and diameter of birch trees, leading in consequence to the appearance of an older sapling phase for most regenerations of this species. This creates the possibility of early undercanopy planting of tree species adjusted to the site conditions, mainly silver fir (Abies alba Mill.) and European beech (Fagus sylvatica L.).

    Opis:
    The subject of the study was a population of Sorbus torminalis resulting from spontaneous regeneration from seeds in northern Poland at the north-eastern limit of the species distribution. The population, occupying a fenced plot of 1.72 ha in the Forest District of Jamy, amounted to 579 individuals of variable age classes up to about 19 years old. Six polymorphic gene loci: MDH-B, ME-A, 6PGD-B, ADH-B, PGM-A, PGM-B were studied in 532 individuals recruited post-fencing and 21 potentially parental, adult trees. The analysis showed similarly high levels of genetic diversity within both subsets of individuals but there was also a noticeable change in genetic structure between them. Detailed genetic analysis of the post-fencing recruits revealed lack of significant differences between different age groups based on DBH within the fenced plot.

    Opis:
    Gap regeneration in a European beech (Fagus sylvatica L.) forest reserve was analyzed in relation to within-gap resource heterogeneity and ground vegetation competition. The study was carried out in two one-hectare permanent research plots (PRP) which included five smaller research plots (RP) encompassing two large gaps (500–700 m2), two small gaps (300–400 m2), and location under canopy. The coverage of woody regeneration, ground vegetation, dead wood, seedling density in eight height classes, characteristics of dominant trees of the beech regeneration, and the total thickness of holorganic horizons were measured. Soil moisture and light conditions were also assessed in selected sample plots. The relative direct and diffuse light was estimated by hemispherical photography. Small gaps showed both the highest cover of tree regeneration and the highest density of individuals per hectare. Slightly less regeneration was recorded in large gaps, while under closed canopy, regeneration densities were 5–10 times lower than in small gaps. Beech regeneration cover and the size (diameter and height) of dominant beech seedlings were positively related to relative diffuse light and negatively related to ground vegetation cover. The latter was positively related to diffuse light and soil moisture content. A pronounced statistically significant contrast in the cover and size of beech regeneration in relation to micro-site conditions (diffuse light, cover of graminoids) was only confirmed between sample plots located below canopy cover and those within gaps. Graminoids, in particular Calamagrostis epigejos L., occurred mainly in the large gap centre and along the southernmost edge of the large gap, increasing competition for resources here. The cumulative cover of ground vegetation and regeneration was relatively low (9–56%) compared with more mesic natural beech forests. The indicated negative influence of direct light at the northern gap edge suggests that extension of gaps on comparable sites in managed forest should not proceed in this direction.

    The paper discusses conditions and problems concerning natural regeneration of pine in the „Puszcza Białowieska” Promotional Forest Complex. The studies on pine regeneration established from self−seeding were carried out on permanent experimental plots occupied by fresh and fresh mixed coniferous forests site types. A space filling index used in the experiment was to define space occupied by pine regeneration the so−called „height sum”. A significance test of differences in mean values between the abundance and height sum (t−Student's test) was used for each experimental variant within the forests site types. Natural regeneration in the Białowieża Forest occurs infrequently. It can be found mainly in loose pine stands growing in fresh coniferous forest site types. Pine naturally regenerates most successfully in fresh and fresh mixed coniferous forest site types, on fenced clear−cuts with a few reserved trees, with soil prepared in furrows and well−performed tending treatments, as well as in pine stands with stocking 0.4 providing that the same conditions are maintained. The primary condition for successful natural regeneration of pine in the Białowieża Forest is its protection against animals in the form of fencing.

    The paper presents the state and conditions of oak natural regeneration in the „Białowieża Primeval Forest” Promotional Forest Complex. It has been stated that under natural conditions oak appears in all forest types but it infrequently grows into a stand. With the recent expansion of hornbeam, it is difficult for oak effectively to regenerate. It has been confirmed in this study that the shelterwood cutting system (leaving some trees to dye naturally) is the most efficient method of natural regeneration of oak in the Białowieża stands.

    The silver fir (Abies alba Mill.) in the area of Wał Trzebnicki is at the northern limit of its distribution in western Poland. This study was performed in three nature reserves with protected silver fir populations. The stands in these reserves were mixed, with complex spatial structure and abundant tree regeneration. The proportion of fir in stands was around 16% of DBHS, the age of trees reached around 130 years. The silver fir occurs mainly in the sapling stage, whereas the number of seedlings was very low. The results of this study show the influence of forest floor vegetation as well as litter type on the emergence of fir seedlings. The seedlings density was compared with the results of other studies from different geographical areas and stands type in Poland.

    Opis:
    In Central Europe, deforestation led to a reduction of forest area by almost 80%, compared to the original area, by the beginning of the 20th century. At this point in time, a period of intensive reforestation began in an effort to restore forest areas. This process of reforestation, especially on post-agricultural land, continues to this day. This article examines reforestation and natural regeneration on former farmland and the factors that influence the current state as well as the future growth of the forest. Ancient and contemporary views on the functioning of stands on post-agricultural land created by both, natural and forced succession (i.e. afforestation), are recalled. In Poland, this issue primarily concerns managed state forests, which cover an area of over 2 million hectares. We discuss the differences in the development of these stands resulting from the history of agricultural cultivation, the type of afforestation, the influence of environmental factors as well as biotic threats to their development. Furthermore, the need to change the silviculture-, protection- and endowment-based approach to forest management in stands on post-agricultural land is highlighted.

    Opis:
    In the last decades, we observed significant changes in the tree species composition in all layers of close−to−natural stands. Since the 1970s, the Forest Research Institute has collected and stored dataset from stand measurements, phytosociological and other research that are the basis for the long−term monitoring of vegetation. The aim of the research was to determine the directions of changes in the species composition and structure of tree stands, and to analyze the changes in the species composition of natural regeneration growing without human interference in various forest communities in the period of about 40 years. From 2014 to 2017, 40 permanent plots of 0.25 ha were re−measured in the nature reserves of the Knyszyn and Augustów Forests (NE Poland). The diameter of all trees was measured and the trees of the natural regeneration and bushes up to 1.3 m high were counted. The stand similarity index (S) between successive measurements was calculated. The analysis of differences in the composition of tree stands in subsequent measurements was carried out using Student t and Kruskal−Wallis tests. In the species composition of fresh coniferous forest stands and fresh mixed coniferous forest, there were significant changes in the number and share of Scots pine and Norway spruce. In the Knyszyn Forest a significant decrease in the share of spruce was observed. However, an increase in the share of deciduous species was remarkable. An inhibition of the natural pine renewal process and increase in density of spruce regeneration was observed. It is necessary to emphasize the significant expansion of hornbeam in a fresh mixed deciduous forest in the Knyszyn Forest and expansion of hazel in the Augustów Forest. Mean basal area in the forest stands has increased. The similarity index between the beginning and the end of the research reached the value of 0.73−0.94. The species composition and density of natural regenerations created without human intervention are not satisfactory from the point of view of forest sustainability. The most important factor affecting the direction and rate of changes in the species composition of tree stands is the expansion of hornbeam and/or hazel. These species cause changes in the ecological conditions of the lowest forest layers, leading to the unification of the species composition of forest communities.

    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.
