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:
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:
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.

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.

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.
