Opis:
Spatial distribution of trees in natural trees stands were investigated seven times in period between 1936 and 2001. The obtained results suggest that small tees are often clumped but when time goes on groups disintegrate and more spaced pattern emerge. Bigger and the biggest trees usually are randomly distributed but seldom the biggest trees are distributed evenly. Such dynamics prove the idea of competition as a factor shaping forest trees distribution and contradict idea of biogrups which assumes collaboration between trees in a clump.

Opis:
In detailed silvicultural planning, good knowledge of the internal situation (e.q. placement of advanced regeneration) in stand survey units is necessary. Information gathered in the framework of regular forest survey is not sufficient, specifically when natural stand regeneration is planned. The application of GPS is a practical, inexpensive, quick to operate technology of collecting information required for silvicultural planning and positioning spatial elements of a cutting system. As silviculture needs do not require such a high accuracy as in the case of positioning of stand survey units, it seems that the application of tourist−class GPS receivers is an optimum solution. This class equipment is inexpensive and easy to operate. The knowledge about possibilities which GPS receiver provides on the one hand and the awareness of limitations that forest environment creates for GPS measurements helps make a reliable draft of a stand's internal situation.

Opis:
Optimisation of patch selective cutting, especially the interaction between size and shape of artificial gaps and biotic factors influencing tree regeneration, is rather sparsely documented in Polish silvicultural textbooks. The removal of trees can increase availability of nutrients in artificial gaps. Establishment of root gaps and vigorous development of vegetative cover (weeds) is another consequence. This paper presents review of investigations that describe interactions between mentioned factors influencing regeneration growth and parameters of gaps. The special attention is paid to potential application of cited results in practical silviculture.

Opis:
Paper compares various analysis methods suitable for an analysis of point pattern with directionally varying point density. As example was used point pattern from spacing experiment created according to Nelder design in which tree density changes greatly but in smooth manner. Such a pattern could be not analysed by methods assuming homogenous point density e.g. classical estimator of Ripley's K function. More useful are estimators of Ripley's and pair−correlation functions for inhomogeneous point patterns. K2 function, which proved to be efficient for heterogeneous point patterns with distinct changes in the local point density appears not to be efficient for heterogeneous point patterns with smooth changes in density.

Opis:
The spatial variability of the density of Scots pine and silver birch natural regeneration in gaps has different pattern in subsequent development stages. The pine seedling density was inversely proportional to the amount of solar radiation reaching the floor in artificial gap estimated by modeling (the highest density occurred in the southern, shaded part of the gap). The top soil layers drying−off that is a result of the insolation is thought to be the main factor limiting seed germination and early growth of both species, however pine response at this stage was greater. The highest birch undergrowth density was observed in the central part of gaps. It might be the result of relatively low root competition of old trees and a good light supply in this part of the gaps.

Opis:
The Polish forest gap trials report oaks height in the middle of a gap or average height of all oaks in the gap. To decide when the shelter of surrounding old trees in no longer needed and old trees between gaps can be cut, a forester should have knowledge how oaks grow in the peripheral part of gaps. In the experiment height of planted oaks in the age from 5 to 11 years growing in 15 are gaps on fresh mixed broad−leaved forest site was measured. The smallest difference in height of oaks growing in the middle and in the peripheral part of gaps was observed for 5−year−old oaks. The difference became bigger as oaks became older. For oaks older than 8 years, saplings in the peripheral parts are on average 40% lower than those in the central part. The height of older oaks in the middle and in the southern periphery of gap was less differentiated than of oaks growing in northern, eastern and western peripheral parts. Large differences in height can provoke oaks to develop bad stem forms (e.g. forked, thick branched). Special care should be taken during pre−commercial thinning to eliminate oaks with bad stems in the peripheral parts of gaps.

Opis:
The influence of artificial elliptical gaps (size 15 and 20 are) on height of young (6 and 10 year old) planted pedunculate oaks was investigated on fresh mixed−coniferous and fresh mixed−broadleaved forest site types. For each combination of age, site type and gap size four gaps were sampled. In each gap, 3 circular sampling plots of 3 m radius were placed in northern, central and southern part of gap. The analysis were carried out separately for 6− and 10−year−old oaks and proved that gap size did not have an influence on height of younger and older oaks. In both cases, site type influence had statistical importance, but the practical silvicultural importance of this difference was only for older oaks. The position within gap was not important for growth of younger oaks, but had an influence on the height of older ones in different manner in different site conditions. The mean height of older oaks growing in more fertile conditions had maximum value in the centre of artificial gaps and diminished towards the periphery. On less fertile site types older oaks were the lowest in the northern position and their height in southern and central part of gaps was comparable.

Opis:
Long distance dispersal is a key process occurring in plant communities and is particularly important for pioneer species like sea-buckthorn (Hippophaë rhamnoides L.) which survival strongly depends on colonizing newly created post-disturbance habitats. Sea-buckthorn, a cluster-forming shrub, is commonly used in Poland in the reclamation of soil-less areas devastated the by mining industry and for these areas a generative expansion of planted populations is usually observed. The main objective of this study was to assess the long-distance dispersal of this species in areas previously disturbed by industrial activity. Our observations were made on a 223.75 ha large section of the internal waste heap of the Bełchatów lignite mine, Central Poland. The area was colonized by sea-buckthorn specimens originating from a population planted on the nearby external waste heap. During the search for newly established sea-buckthorn clusters, their position and size were recorded and the preferences for specific site conditions were assessed using the Ivlev's electivity index. New specimen were observed at distances between 600 m and 3600 m from their potential seed source. The mean cluster density was 1.37 ha-1. The observed pattern of long distance dispersal is linked with to behavior of frugivorous birds. The largest cluster densities were observed along ditches (9.83 ha-1) and on open areas with less developed plant cover, while the lowest cluster density occurred in afforested areas (0.51 ha-1). Poor sandy substrate reduced the probability of plant establishment compared to richer loamy sands. There appeared to be no influence of slope aspect on the probability of sea-buckthorn establishment.

Opis:
The formation of the stand structure interacts with the processes of growth and competition. Previous observations mainly focused on the analysis of the type of tree distribution resulting from these processes. Development of spatial diversity of tree parameters is less known issue. The research was carried out in mountain Norway spruce stands with a large variety of taxation parameters located in the Beskid Żywiecki Mts. (southern Poland). The analysis of spatial auto− correlation of biometric features was carried out with the use of the mark correlation function, and the type of tree distribution was examined using the pair correlation function. In younger, less tended stands of high tree density, a stronger spatial autocorrelation of the tree biometric features was found. The strongest autocorrelation was observed for volume, weaker for the breast height diameter, while the weakest one was reported for height. The analysis indicated that density dependent competition affects the autocorrelation of biometric features more strongly than the type of tree distribution. The range of the tree perception zone determined on the basis of the autocorrelation analysis of features is greater or equal to the width of the inhibition zone determined on the basis of the point pattern type analysis.

Opis:
The paper describes the results of investigation on the range of trophic abilities and preferences of fungi causing the wood decay of the brown rot pattern. Fomitopsis pinicola, Laetiporus sulphureus, Piptoporus betulinus and Serpula lacrymans fungi were tested. Wooden samples made from wood of 25 different, both European and exotic, tree species were used. They were put on mycelium of every tested fungus. After 30, 60 and 90 days of exposition samples were weighted and the loss of their mass was calculated to compare the differences of wood destroying abilities between examined tree species. The results indicated that the range of trophic abilities in ex situ conditions of tested fungi species was much wider than in nature. All examined fungi were able to decay the wood of more tree species and their trophic preferences occurred to be different as well.

Opis:
The article discusses the environmental impact of the tillage processes of potato production. The analysis was performed using a simplified LCA ( Life Cycle Assessment) software. Depending on the purpose and the level of detail of the process analysis, the LCA technique of environmental management may require computer assistance. Even then, carrying it out is very complex, long and costly. The aim of the study was to explore the possibility of the use of open source software for a simplified life-cycle analysis of potato with LCA method. There was selected OpenLCA – GreenDelta TC GmbH, v.1.3.1 software. The diagrams of unit process streams and energy inputs incurred on the individual processes of cultivation were designed based on literature. There were compared environmental hazards of the two systems of potato cultivation: with using the plough and the simplified one in terms of atmospheric pollution with chemicals emitted by the engines of agricultural tractors in the course of the subsequent agricultural procedures. The study results confirmed the suitability of the software for the initial evaluation (screening) of environmental hazards using LCA method. The software is compatible with both the open source databases and commercial databases. Environmental impacts of cultivation technologies are presented in a form of a graphic illustration of pollution emissions. Also, the problems hindering the use of the software are indicated.

Opis:
Numerous examples of silver fir stands growing outside its geographical range in northern Poland suggest that this species could be used in a greater extend in creation of managed forest stands. Climatic conditions could potentially constrain the use of this species in some parts of country. The objective of this work was to determine the potential climatic range of Abies alba in Poland. The bioclimatic envelope models were used to identify areas in which selected climatic variables show the same range of variability as observed within natural range of this species. Climatic data with 10' spatial resolution were used. The outcome of the analysis depends to large extent on the demarcation of natural range (in which the variability of tolerable climatic conditions is assessed). The model basing on the climatic conditions in whole natural range of silver fir in Europe suggest that almost whole area of Poland is suitable to fir, but models basing only of climatic conditions in Polish part of its natural range are much more conservative. In the last case the difference in extent between natural range and potential climatic range was smaller. As genetic variability of Polish fir populations is rather low, they are supposed to have constrained adaptative abilities. Forest managers should not focus on planting silver fir outside its natural range, but they rather should consider reintroduction of fir in parts of natural range from where it retreated in 20th century.

Opis:
Different kinds of solar radiation (direct, diffuse) shape microclimate of forest gaps and have significant influence on establishment and growth of young trees. Adjustment of the shape and size of artificial gaps could create favourable conditions that meet the demands of particular species. Unfortunately there is lack of publications concerning this topic, which could be used directly for silvicultural planning in Polish conditions. Empirical assessment of radiation regimes in a wide range of different shaped gaps is impossible from practical reasons, so modelling in ArcGis environment was used instead. Gaps of different shape and size were modelled as elliptical depression in terrain by the use digital elevation model. The Solar Radiation tool was used to model direct and global radiation on the bottom of the gaps with area varying between 2 and 50 are surrounded by stands of height between 15 to 35 meters. The outcome of modelling was presented in form of nomograms. Additional series of analyses was created to describe the influence of terrain aspect and inclination on solar radiations supplies on the forest floor in gaps. Presented nomograms could be helpful in silvicultural planning, because they could be used to design artificial gaps with expected solar radiations supplies.

Opis:
The aim of the study was to determine the correlation between ingested forage and composition of microfauna in the rumen of fallow deer. Rumen content of six specimens was obtained from the Bolimowska Forest during 2011/12 hunting season. Protozoa of the Entodinium and Epidinium genera belonging to the Ophryoscoleciade family were identified in analysed samples. Density of Entodinium population was positively correlated with percentage share of forage rich in starch. It was also reversely and equally strongly correlated to the share of forage rich in cellulose (p>0.05). Share of volume and biomass of Epidinium population was correlated negatively with the share of acorns in the forage (p>0.1). Differences in number and share of protozoa of the Entodinium and Epidinium genera in the rumen of fallow deer coexisting in the same place and time indicate feeding opportunism of this ruminant.

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:
Contemporary models of light conditions on the forest floor can be divided into two categories: undercanopy models that allow the light conditions in a stand under the canopy to be simulated, and models that take into account shielding from the side. Under-canopy models precisely estimate the availability of wavelengths of light spatially distributed under the canopy of stands: however these models require a large amount of data on the spatial structure of forest stands. The other class of models describes the light conditions on a particular open surface. These incorporate shielding from the side and are easier to use as they require less data than under-canopy models. In practice, in forest conditions, such models require data on the size, shape, and geographical location of surveyed surfaces (e.g. gaps, and cut areas) and on the height of the surrounding stand. Often, these data are available in databases, such as the State Forest Information System (SILP), can otherwise be obtained relatively easily (and inexpensively). Compared to under-canopy models, these models provide a cheap way to obtain useful information on variation in the light environment that affects the microclimate for regenerating plants on clearcuts and canopy gaps.

Habitat preferences of capercaillie Tetrao urogallus in the Augustowska Forest (NE Poland) were evaluated using classification trees. Data were collected on 1033 circular sampling plots localized on leks and in their vicinity with 1 km radius. Gathered information described tree stands (site conditions, age, species composition, tree density, closure, vertical structure, lower strata coverage (saplings and shrubs) and blueberry coverage (Vaccinium myrtillus) as well signs of capercaillie presence. The analysis shows that for capercaillie of key importance are tree stands growing on fresh or wet coniferous sites, more than 100 years old, with density less than 446 trees/ha, with anthill and situated more than 150 from a road.

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.

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.

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.
