    Opis:
    The article is a continuation of research on the relationship between forest habitat type and economic aspects of forest management. It assesses the impact of forest habitat types on reforestation costs. As a part of the implementation of the assumed work objectives, economic activities related to afforestation were identified. The research was carried out using the passive experiment method. The research was of registration and observational character. During the acquisition of the necessary data, there was no interference in the forestry work. The costs were analysed in three categories: total costs, tangible costs and intangible costs. Research conducted on the basis of source data obtained from 629 forest plots with a total area of 1100 ha. Based on the results of the research, it was found that the type of forest habitat significantly differentiated all the analyzed costs of reforestation. The forest habitat type differentiated material costs (48%) to a greater extent than intangible costs (43%). In addition, reforestation of deciduous forests has been proven to generate higher forest renewal costs than coniferous forest habitats. The costs of forest regeneration in forest habitats were higher than the costs incurred in coniferous habitats. Information on differences in forest management costs in relation to forest habitats can be used in further research on the forest management support system. The presented research contributes to the development of work on building economic models of the stands. These models must take into account not only the general economic aspects, but also the natural aspects of the forest that affect financial flows related to forest management.

    Opis:
    On the basis of forest taxation data the presence of European ash in the Bardzkie Mountains area (central part of the Sudety Mountains) was analysed. This included the reckoning of the number of sites and the area covered by ash in various forest habitat types, age classes, altitude zones and on variously slanted and exposed mountain sides. The decline in the number of ashes in younger age classes and complete absence of trees older than 140 years have been noted. In the Bardzkie Mountains ash is the main species forming the forest on mountain riparian forest stands (a 43% participation in the area of forest of this type). Considering the number of specimens most ashes are scattered in mountain broadleaved forest. To the altitude of 650 m ash’ participation in the forest stand composition is stable (30% of analysed locations), but it occupies only 2.6% of total forest area.

    Opis:
    The aim of the study was to assess the susceptibility of small-leaved lime (Tilia cordata Mill.) seeds to drying and freezing in liquid nitrogen (-196°C). Seed samples were frozen in liquid nitrogen for 24 h at 11 different levels of seed moisture content (m.c.), ranging from 3.1% to 22.8% (fresh weight basis). All samples, including unfrozen control samples, were subjected to scarification with concentrated sulphuric acid (Tylkowski 1998) either before or after freezing. Seed pre-treatment before germination (at 3~15°C/16~8h) involved cold stratification at 3°C without substrate. Seed drying to 3.1% m.c. significantly reduced their germinability (to 63%), as compared to the high germinability (82-88%) of seeds with 5.2-20.9% m.c. Thus seeds of this species can be assigned to the ‘suborthodox' category. Such a high germinability (79-87%) was preserved after freezing in liquid nitrogen in samples dried to 9.0-17.4% m.c. if scarification was performed before freezing, and in samples dried to 9.1-16.2% m.c. if scarification was performed after freezing. The highest percentage of seedlings emerged after freezing in liquid nitrogen from seeds dried to 11.1-20.1% m.c. (emergence 65-75%) if scarification was performed before freezing, and from seeds dried to 7.3-17.8% m.c. (emergence 53%-71%) if scarification was performed after freezing.

    Opis:
    W pracy analizowano możliwości zastosowania wskaźników liczbowej wyceny gleb: ITGL oraz SIG (Brożek 2001; Brożek i in. 2001, 2006) do opisu zmienności siedlisk kształtujących się na zrekultywowanych dla leśnictwa zwałowiskach KWB 'Bełchatów'. Badania prowadzono w czterech wariantach substratów stanowiących skały macierzyste dla powstających gleb: zasobniejszych, piaszczysto-gliniastych czwartorzędowych (NWL na zwałowisku wewnętrznym) i gliniasto-pylastych (NZL na zwałowisku zewnętrznym) oraz uboższych, czwartorzędowych piaskach (NWG na zwałowisku wewnętrznym) i kwaśnych mioceńskich piaskach po neutralizacji kredą jeziorną (NZG na zwałowisku zewnętrznym). Na podstawie obliczonych wartości testowanych wskaźników dokonano wyceny siedlisk według skali opracowanej dla warunków 'naturalnych'. Stwierdzono, że spośród dwu testowanych wskaźników w warunkach zwałowisk KWB 'Bełchatów' lepiej odzwierciedlającym zmienność badanych gleb był ITGL. Jednak dla lepszego opisu siedlisk kształtujących się w tych warunkach należałoby zmodyfikować wycenę wskaźników cząstkowych omawianych indeksów, opierając się na zmienności właściwości gleb pogórniczych.
    In this work the analyses of possibilities of using soil quality indexes ITGL and SIG (according to Brożek 2001; Brożek et al. 2006) were presented for description of forest habitat developed on spoil heap 'Bełchatów' reclaimed to forest. The study was conducted on 4 substrate variants with different parent rock material: 1) higher level of fertilize - Quaternary loamy-sands (NWL on external slope) and loamy-silt (NZL on internal slope); and 2) lower level of fertilize - Quaternary sands (NWG on internal slope) and acidic Miocene sands strata after bog lime neutralization (NZG on external slope). Based on value of calculated indexes the site quality estimation was made according to scale worked out for natural forest habitats. It was concluded that from among two soil quality indexes the ITGL showed better variability of soil conditions on spoil heap 'Bełchatów'. However the modification of partial indexes of ITGL for better description of site condition on this kind of object has to be necessary with adjusting of post-mining soil characteristics.

    Opis:
    In July, 1992, fire swept through the Jelonka Reserve (52o35'33"N; 23o22'10"E). Litter, herbs layer and juniper shrubs were razed and the tree trunks of Pinus sylvestris and Populus tremula damaged, which resulted in their death the following year. Five research plots of 25 m2 each were established in the post-fire area. The species present there and their degrees of coverage were listed on the Londo scale between 1993 and 2002. The calculation of average degrees of coverage for individual populations allowed for the establishing of a chronological pattern of post-fire succession. The following findings have been made: 1) the primary function in colonization belongs to species of guerilla strategy of growth whose dormant buds survived fire underground (Holcus mollis, Calluna vulgaris and Populus tremula) or phalanx strategy of growth (Corynephoms canescens); 2) the dominants of the initial succession stage are perennial grasses, not therophytes; 3) the spatial pattern of succession is influenced by the occurrence of H. mollis or C. canescens in a particular location; 4) the initial stage terminates with the occurrence and further growth of C. vulgaris clumps; the post-fire succession in the Jelonka Reserve attained a brushwood stage faster in comparison to secondary succession, formerly triggered by the cessation of cultivation on arable land.

    Opis:
    Integrating the economic aspects of forest management (cost) with ecological elements of timber production (habitat type) significantly contributes to a better understanding of forest growth and utilisation. The type of silvicultural treatments and forest habitat types determine number of economic activities carried out in the stands and have an important impact on the associated costs. The aim of the study was to describe the impact of silviculture treatments and types of forest habitat on unit timber harvesting cost. We summarised the cost of timber logging depending on the harvest practices and types of habitats. In total, costs of treatments performed on the 2.5 thousand ha area were analysed. Obtained results were combined in relation to average unit costs of raw timber logging from individual habitats and silviculture treatments such as late cleanings and thinnings. The studied impact was assessed with standard deviation (SD) based on the assumption that the higher its value, the more important role of silvicultural treatments and forest habitats in defining the cost of raw timber harvesting. Our study showed that both factors (type of forest habitat and silvicultural treatment) had an effect on variability of timber logging costs. Comparing deciduous and coniferous habitats, higher costs were reported for the latter one. The highest unit cost of timber logging was found on the fresh coniferous habitat, while the lowest on the wet mixed forest. Moreover, the highest cost was reported for timber raw material harvested from late cleanings and the lowest from late thinnings. SD of the average cost of timber harvest ranged from 12.67 to 13.53 PLN depending on the silviculture treatments and from 0.68 to 2.39 PLN depending on the forest type. Our findings are important preliminary steps in broader study regarding revenues generated from forest stands growing on different habitats. Eventually it would help in assessing the profitability of economic activity that depends on environmental conditions of forest management.

    Opis:
    There is a lack of an acceptable and practical method for calculating the optimal moment at which a forest stand is considered ready for felling. The aim of the research was to: (1) develop a concept for the calculation of the rotation age for forest stands based on economic criteria and (2) develop a methodology for obtaining and processing empirical data necessary for such calculation. It is assumed that stands are felled at the age affecting the age structure (area of age classes) of a forest in such a way that the difference between revenues from the sale of timber harvested in inter−mediate cuts and final cuts and the costs of timber harvest, silvicultural management, forest protection and administration is the largest. The developed method of calculating the rotation age was tested on the example of three Scots pine forests under the clear−cutting system representing typical forest habitats. The collected empirical material consisted of (1) own measurement data used to determine the value of the growing stock, and (2) data from the State Forests Information System used to determine the management costs, timber prices and the volume of timber harvested from intermediate cuts. These data helped to calculate the relationship between the income from a forest (including: revenues from the final and intermediate cuts, costs of forest management as well as timber harvesting and extraction) and the rotation age. The highest net income was when the rotation age was 108−125 years. The more fertile habitat, the shorter was the rotation age. The proposed methodology can be treated as a useful tool for the calculation of rotation age related to forest management in Poland. The dependence of income from a forest on the rotation age can be used to calculate losses that may arise when other than an optimal rotation age is applied.

    Opis:
    The article presents the size and weight of needles in 30−year−old Scots pine stands over one year with regard to the site conditions in which they grow (fresh mixed coniferous and fresh coniferous habitats). Two rectangular 1−hectare sample plots, which differed from one another only with the habitat type, were set up in Maszewo forestry in the Cybinka Forest District (western Poland). The plots were divided into 100 one−acre subplots, which were ascribed numbers from 1 to 100. In order to pick 10 plots a random number generator was used. The middle of the chosen plot became the central point of the 1−acre circular sample plots, where the measurements of all diameters at breast height and the height of every fifth tree were taken. Moreover, it was also the place where a square needle collection container (20 cm high, 1 m2 area) was located. The empty containers were placed in both experimental plots on 1st August 2017 and they were emptied on the first day of each month, throughout the entire year. The entire material was dried at the temperature of 65°C with an induced air flow. The needle mass was measured with the accuracy up to 0.001 g. Out of the samples collected each month, 300 needles were chosen at random in order to measure their length (after they were scanned with WinFOLIA program the size of each individual needle was established). Throughout the entire year, on fresh coniferous habitat the mass of the fallen needles was 2.8203 t/ha and it was by over 20% higher than it was determined for the fresh coniferous habitat. The lowest mass of the needle fall in each stand was in January, and the greatest in September on the fresh coniferous habitat, whereas in October on the fresh mixed coniferous habitat. In both of these cases, it was more than a half of the needle mass for the entire year. The average length of the fallen needles was in each month smaller on the fresh coniferous habitat and the differences between the analyzed stands were significant. The difference was the smallest (3.3%) in May, while the greatest (18.8%) in February. Moreover, significant differences in the length of the needles in the particular months in both types of stands were observed. The coefficient of variation for the needles length on the fresh mixed coniferous habitat ranged from 17.4 to 22.8%, whereas on the other habitat it varied between 14.2 and 21.6%. The mean of the coefficients of variation for the particular months was lower by 2.0% and for fresh coniferous habitat it reached 18.25%.

    Opis:
    Two main typological systems (forest habitat types and phytosociological classification) are used in forest research in Poland. The paper presents relationships between forest associations and forest habitat types in mountain environment of the Promotional Forest Complex ‘Sudety Zachodnie' (SW Poland). The results show that the link between these two topological systems is rather weak and ambiguous. This has strong implications for nature conservation in Poland, where forestry databases are widely used for inventories of protected habitats (in the sense of Habitat Directive).

    Opis:
    Investigations have been carried out on the soil material taken from 46 profiles representing lithogenic soils from non-forest areas of the Tatra National Park. When selecting soil material an altitude above sea level (over 1250 m a.s.l.), a rock parent type (non-calcareous and calcareous) were taken into account, in case of non calcerous soils, the weakly developed soils - rankers were selected. On the basis of the investigetions the following conclusions have been drawn: sorption properties of ectohumus horizons in most of investigated lithogenic soils (rankers and rendzinas) are differ- enciated and formed under the influence of parent rocks. Ectohumus of Oh horizons of rankers sorbed exchangeable cations in following order H+>Ca2+≥Mg2+>K+>Na+. In composition of cations in Oh horizons of rendzinas dominated cations of calcium and the order was as follows: Ca2+>Mg2+>H+>K+≥Na+. In ectohumus of Oh horizons of rendzinas occurring under bilberry heath and pine dwarf and rankers the composition of exchangeable ions as well as a degree of base saturation were close. In investigated soils sorption properties of mineral or organic-mineral horizons AC or ABC, occurring in direct contact with the parent rock, were formed under the influence of lithogenic factor.

    Opis:
    Powierzchnia gruntów wymagających rekultywacji w Polsce wynosi ponad 64 tys. ha, w tym w przemyśle wydobywczym około 44 tys. ha. Dominującym kierunkiem rekultywacji jest kierunek leśny (około 60%). Zwały odpadów górnictwa węgla kamiennego w rejonie GOP należą do obiektów uciążliwych dla środowiska i często powstają na terenach wyłączanych z produkcji leśnej. Znaczna część rekultywowanych i zalesionych zwałowisk przekazywana jest pod administrację LP. Tereny te obejmowane są Planami Urządzania Lasu, w których zawarta jest charakterystyka siedlisk i drzewostanów. Celem niniejszej pracy była analiza powierzchniowa rekultywacji leśnej, wieku i składu gatunkowego drzewostanów oraz prognozowanych siedliskowych typów lasu na zwałach znajdujących się na terenie Nadleśnictwa Rybnik (rejon GOP). Stwierdzono, że na analizowanym obszarze powierzchnia wyłączona z produkcji leśnej dla tworzenia zwałowisk wynosiła 254,5 ha, zaś powierzchnia zrekultywowana wynosi 132,3 ha. W większości siedliska na zwałach zdiagnozowano jako BMśw (53%), a dominującym gatunkiem jest sosna zwyczajna (40%), w tym w znacznej części pochodząca z samosiewu. Drzewostany znajdują się aktualnie w I i II klasie wieku. Wyniki pracy mogą mieć znaczenie dla planowania hodowlanego w odniesieniu do drzewostanów na rekultywowanych zwałach.
    The surface areas requiring reclamation in Poland amounts 64,000 ha, of which, 44,000 ha are occupied by mining. The predominant reclaimed postmining use is forestery (60%). In the area of Upper Silesia, spoil heaps pose a threat to the environment, and they are often deposited on surfaces excluded from forest production. The majority of these reclaimed and afforested spoil heaps is transferred to the administration of The State Forests National Forest Holding (Lasy Państwowe). These areas are included into the Forest Management Plan andcontain characteristics of both forest sites and tree stands. The aim of this study was to analyze the area of forest reclamation, tree stand age, species composition and forest site classification on spoil heaps located in the Rybnik Forest Inspectorate . Findings show that in the analyzed area, surfaces excluded from forest production amounted 245.5 ha, and the surface of reclaimed area amounted 132.3 ha. The majority of these areas were defined as young, mixed coniferous forest sites (BMśw 53%). Scots pine (Pinus sylvestris L.) is the predominant species (40%), dervived mostly from self-seeding andstands are in the first or second age class. The result of these studies can be important during silviculture planning and management for tree stands on reclaimed sites.

    Opis:
    The present research (1998-1999) was carried out to evaluate soil enzymatic activity in the deteriorated forest ecosystems within the operation range of the Puławy S.A. Nitrogen Factory. Investigation covered podzolic soils from strong and medium forest pollution zones. Objects from the Pulawy Forest Inspectoratejwere represented, i.e. samples from the Puławy district (Inspectorate Wronów) and Żyrzyn district (Inspectorate Zagórki). The obtained results indicate high degree of soil environment deterioration in the investigated forest habitats, in the form suppressed enzymatic activity and deformation of chemical properties. A significant increase in the enzymatic soil activity with the increasing distance from the nitrogen factory was observed. Changes in the activity of soil enzymes were related to the soil chemical properties.

    Opis:
    The study presents the results of MANOVA of tree slenderness. The study material comprised 72 larch trees in a dominant stand of different age classes growing in fresh mixed coniferous (BMśw), fresh mixed deciduous (LMśw) and fresh deciduous (Lśw) forest habitats. The slenderness of each larch tree was calculated as the ratio of tree height [m] to breast height diameter [cm]. Basic statistical characteristics were also established. A three−way analysis of variance was performed assessing the statistical significance of the impact of forest habitat type, age and biosocial position of trees in the stand. A similar analysis was done for two basic measurement characteristics of trees – breast height diameter and height.

    Opis:
    The paper presents the results of the study of changes in the normal volume of absorption capacity of soil skeletons formed from the Magura sandstone in the Beskid Makowski area, and sampled from different genetic horizons. In the field of hydrology, the key issue in assessing the water storage capacity of the soil cover storage reservoir is the water storage capacity of the skeleton part. In the case of mountain soils, the issue of determining water storage capacity seems to be of importance due to the significant share of skeleton fraction in the soil cover. Moreover, the absorption capacity of the skeleton is related to the fraction volume. Soil test pits were executed in the area of Myślenice Forest District (southern Poland), in the habitat of Carpathian beech species Dentario glandulosae−Fagetum, in a stand of fir and spruce Abieti Piceetum. The scope of field work included sampling of 6 test profiles. In each profile, samples were taken from three identified genetic horizons. Sieve analysis method was used to determine the total content of skeleton and fine earth, and percentage share of each fraction. For each skeleton fractions, normal absorption capacity and bulk density were found. An important, supplementary part of the study was the isolation of fine−grained and coarse sandstone in each sample. After such processing, the collected material was compared with the material remaining after the successive stages of soil skeleton abrasion (weathering) in an aqueous medium, according to methodological assumptions. A device was used to perform this stage of the study. Changes in water storage capacity were mainly considered taking into account the fraction size and the location depth in a soil profile (without specifying the thickness changes). Differences were found between the absorption capacity of skeleton occurring naturally in the soil, and water absorption capacity of skeleton devoid of the outer layer of detritus as a result of the abrasion method. Water storage capacity values were decreasing after each successive step of the experimental run, along with increasing fraction size and the depth of their position in the profile. Preliminary results showed that the changes of absorption capacity are more strongly correlated with size of the fraction than with position in a genetic horizon.

    Opis:
    Ectomycorrhizal communities associated with Pinus sylvestris growing on dry coniferous forest habitat after the fire were studied. In order to investigate the fire effect on ectomycorrhizal fungi and changes of soil parameters in the upper (0−15 cm) soil layer three study plots were established: 1 – the control, 2 – fire zone left for artificial renewal (with the economic method of renewal) and 3 – fire zone left for natural renewal. The analysis of mycorrhizae revealed presence of eight mycorrhizal fungi on Scots pine roots and the value of Shannon−Wiener species diversity index H’ equaled to 1.76. The most abundant were mycorrhizae formed by Tomentella feruginea (31.7%) and Hebeloma crustuliniforme (23.3%). The fraction of Paxillus involutus and Rhizopogon sp. mycorrhizae was 16.7% and 13.0%, respectively. The lowest was the number of Thelephora terrestris mycorrhizae (only 1.7%). At the site 2, number of mycorrhizal fungi diminished to five and Shannon−Wiener species diversity index was also lower (1.37). The predominant were mycorrhizae of Cenococcum geophilum (26.7%) and P. involutus (21.7%), whilst the lowest were mycorrhizae of Suillus luteus (1.7%). Although at the third site the number of ectomycorrhizal fungi was the same as on the site 2, the dominance of Thelephora terrestris (66.7%) caused that Shannon−Wiener’s species diversity index was the lowest (1.05). Mycorrhizae of Paxillus involutus and Wilcoxina mikolae were characterised by similar abundance (13.3% and 11.7%, respectively). The lowest number of mycorrhizae was observed for Tomentella sp. (3.3%). Analysis of soil parameters showed an increase of pH on burnt sites in comparison to the control. The soil of burnt sites were also characterised by lower value of C and C/N ratio than the soil on the control treatment. The result showed that ubiquitous mycorrhizal fungi, such as T. terrestis, are able to persist on roots in changed soil environment with low content of nutritions.

    Opis:
    Deep dystric Cambisols developed on the homogenous regoliths of granite in the Stołowe Mountains National Park (SW Poland). In general, the soils have a texture of gravelly sandy loam, apparently silty, the strong acid reaction and the base saturation below 30% throughout the profile (oligotrophic variant). Only the soils developed in lower parts of slopes have a base saturation up to 40−50% or more (oligo−mesotrophic and mesotrophic variants respectively). These soils rich in humus and biologically active create in the low mountain zone the habitats suitable for the mixed mountain forests and, in a less acid variant, for the broadleaf mountain forests. Combined trophic soil index reached the values from 29 to 33 that confirmed mesotrophic type of the forest habitats. Most Cambisols developed from granite in the Stołowe Mountains are currently covered with spruce stands of artificial origin. However, a phytosociological analyses of vegetation carried out in preserved beech stands documented the presence of Luzulo luzuloidis−Fagetum community of poor beech forest that should be considered a potentially natural forest community on these soils and the strategic goal of the forest reconstruction in the national park.

    Opis:
    The aim of this study was to evaluate the soils from the Old Town in Szczecin (NW Poland) as a potential forest habitat using the Forest Soil Trophism Index (ITGL). For this purpose, six drillings were made, from which the samples of anthropogenic materials were taken. The method of soil material collection for the study did not allow the determination of bulk density required to calculate Soil Trophic Index – the indicator currently used in forest science. The methods commonly used in the soil sciences were used to determine the following properties of the soil samples: texture, pH in H2O, pH in KCl, electrical conductivity (EC), organic carbon content, total nitrogen content, base capacity (BC) and total content of Zn, Pb, Cd, Ni, Cr, Cu and Hg. It was found that the soils from the Old Town in Szczecin were alkaline and contained higher amounts of salts and heavy metals (especially Pb and Zn) than natural soils. The degradation degree of these soils was not significantly enough to prevent the succession of vegetation when anthropic pressure ceased. The ITGL values were high, in the range of 38.9−44.5, because of the presence of organic carbon in whole soil profile, which was also rich in nitrogen, high values of pH in H2O and base capacity. The ITGL values indicated the hypertrophic character of soil materials and potential habitat of the fresh broadleaved forest. After the colonization of tested area by pioneer species of trees, one expects the dominance of beech, oak, maple and linden, i.e. species frequently occurring in the immediate vicinity and at the same time the species constituting of potential vegetation for the Baltic Natural−Forest Province.

    Opis:
    Chemical properties and fertility of soils were compared under spruce, mixed and beech stands in four types of forest habitat (mountain broadleaf forest, mountain mixed broadleaf forest, mountain mixed coniferous forest and mountain coniferous forest) in 373 sites of forest monitoring in the Stołowe Mountains National Park, SW Poland. Soils under the spruce stands had higher organic carbon pools in their upper horizons, but lower pH, increased activity of exchangeable aluminum, lower contents of exchangeable base cations, available potassium and magnesium, resulting finally in lower values of the soil trophic index (SIG). The negative impact of spruce monocultures on the physicochemical soil properties was much stronger in the eutrophic habitats (dedicated to broadleaf forest) than in dystrophic ones. Weak positive effect of the beech introduction on soils in the dystrophic habitats indicated that the conversion of the coniferous into mixed or deciduous stands would not cause a rapid improvement in the physicochemical properties deformed previously under spruce monocultures.

    Opis:
    Relic Pinus cembra forests were among the least studied plant communities in the Western Car- pathians. Their distribution in this mountain range is limited only to the Tatras. The lack of comprehensive research on the Polish and Slovakian sides of the Tatras led to considerable discrepancy regarding their distribution (300–1170 ha) as well as habitat conditions. Their occurrence on limestones and in the West- ern Tatras was contested. Therefore, the aim of this work was to determine the distribution and habitat conditions for the occurrence of Swiss stone pine forests in the Tatras. We mapped the entire range of the distribution of these forests, using the topographic method and digitized it in ArcGIS 10.2.2. Afterwards, we undertook spatial analysis, using DEM regarding their occurrence, depending on: altitude, inclination, solar radiation, exposure, geology and soil. To determine the preferable site conditions we used the logistic regression model. The total area of P. cembra forests in the Tatras is 916.93 ha. They occur in all mountain ranges within the Tatras. Altitude, inclination and solar radiation have significant impacts on the occur- rence of these forests. The odds of the occurrence of P. cembra forests increased by 0.5% for every 1 m of altitude, by 2% for every 1° of inclination and decrease by 0.1% for every 1 MJ/m2/year of solar radiation. The majority of these forests grow in the altitude range 1300–1650 m a.s.l. (95%) and on slopes with 20–60° inclinations (80%). Swiss stone pine forests occur both on slopes with low (1900 MJ/m2) and high annual solar radiation (3400 MJ/m2). They prefer slopes with North-western exposure. They may grow both on granite and limestone, while the majority of them were mapped on granite. Pinus cembra forests grow on diverse soils, both acidic and alkaline. Nevertheless, most of them occur on Haplic Podzols (52%). The results may be applicable to the Tatra National Park for the conservation and monitoring of this Natura 2000 habitat.

    Opis:
    The study presents the relationships between larch slenderness and age, breast height diameter, height, crown width, crown projection area, crown length and habitat type. The study comprised larch trees in a dominant stand of different age classes growing in fresh mixed coniferous (BMśw), fresh mixed deciduous (LMśw) and fresh deciduous (Lśw) forest habitats. The slenderness of each larch was calculated as the ratio of tree height to breast height diameter. The crown projection area was calculated as a circle with a radius equal to the average radius of the crown. The average crown radius was established after its projection in the four main geographical directions. The crown length was calculated as the difference between the height of a tree and the height of crown location. Also an attempt was made to describe tree slenderness using multiple regression equations.

    Opis:
    The study on the distribution and abundance of beaver families in the Augustowska Primeval Forest was conducted in the years 2000 -2003. It embraced all seven Forest Inspectorates administering the Forest. The study consisted in the penetration of banks along watercourses, lakes and drainage ditches. Lodges, bank dens, dams and the length of the banks colonized by beaver families were plotted on maps. Habitat types contained within the territories of individual beaver families were established on the basis of the maps obtained from Forest Inspectorates. The percentage of bank utilisation by beavers in various types of water bodies was determined. The number of beaver lodges and bank dens, as well as their number per family were established. Also, habitat preferences of beavers in individual water bodies were verified. The presented study has the form of a report which can be used for further monitoring of beaver populations in the Augustowska Primeval Forest.
    W latach 2000–2003 prowadzono badania nad populacją bobrów w Puszczy Augustowskiej. Ogółem w 7 nadleśnictwach stwierdzono 290 rodzin (Tab. 1). Analizowano 5 typów akwenów: rzeka Czarna Hańcza, Kanał Augustowski, inne rzeki, jeziora i rowy melioracyjne. Największe zagęszczenie bobrów w Puszczy stwierdzono przy ciekach i jeziorach. Z ogólnej liczby 290 rodzin ujawniono 35 rodzin na rowach melioracyjnych. W każdym typie akwenów analizą objęto: położenie żeremi, nor, długość areałów rodzin i wybiorczość siedlisk. Określono w % wykorzystanie brzegów akwenów (Tab. 2) oraz długość brzegu zajętego przez jedną rodzinę (Tab. 3), wybiorczość siedlisk przez bobry (Tab. 4, 5, 6). Ponadto określono liczbę żeremi, nor i gniazd łącznie w rożnych akwenach w poszczególnych nadleśnictwach (Tab. 7), a także ich liczbę przypadającą na jedną rodzinę (Tab. 8). Dane dotyczące rodzin na rowach melioracyjnych przedstawiono w tabelach 9– 11.

    Paper presents analysis of differences in conventional wood density of Scots pine measured at breast height regarding the geographical location of stands, forest habitat type, stand age and associated parameters such as density in the mid−length of the stem, density in the upper end of the stem and diameter at breast height. To investigate the impact of these factors, an analysis of covariance was used in accordance with two models specifically developed for this purpose. We found dependence of conventional wood density on the type of forest habitat and geographical location of the stand. The highest density was detected in dry coniferous forests, while the smallest in fresh mixed coniferous forests. Scots pine wood from Zielona Góra Forest (western Poland) characterised with the highest density, while from the Knyszyn Primeval Forest (eastern Poland)− with the lowest.

    Opis:
    Attempts to study biodiversity hotspots on a regional scale should combine compositional and functionalist criteria. The detection of hotspots in this study uses one ecologically similar group of high conservation value species as hotspot indicators, as well as focal habitat indicators, to detect the distribution of suitable environmental conditions. The method is assessed with reference to thermophilous forests in Poland – key habitats for many rare and relict species. Twenty-six high conservation priority species were used as hotspot indicators, and ten plant taxa characteristic of the Quercetalia pubescenti-petraeae phytosociological order were used as focal habitat indicators. Species distribution data was based on a 10 × 10 km grid. The number of species per grid square was interpolated by the ordinary kriging geostatistical method. Our analysis largely determined the distribution of areas with concentration of thermophilous forest flora, but also regional disjunctions and geographical barriers. Indicator species richness can be interpreted as a reflection of the actual state of habitat conditions. It can also be used to determine the location of potential species refugia and possible past and future migration routes.

    Opis:
    The analyses of 4 permanent study plots located in the Białowieża forest (NE Poland, at 52º43´ N, 23º50´ E) were carried out 4 times, first time in 1973 or 1974 and next in 1985, 1998, 2008. The paper presents the results of a long–term study on natural forest dynamics in two forest communities: raised-bog pine forest of the association Ledo-Sphagnetum magellanici Sukopp 1959 em. Neuhäusl 1969 and transitional bogs represented by the boreal spruce forest Sphagno girgensohnii-Piceetum Polak. 1962. On each measurement date the DBH of all trees were recognized. At the same time, stems of shrub species as well as tree species with the height lower than 1.3 m were counted within the experimental areas. During the study period the structure of stands changed significantly. The major change observed on raised bog sites was an increase in numbers of Betula spp., Picea abies (L.) H. Karst. and Quercus robur L. After 34th-year of observations the boreal spruce forest stand partly passed the terminal phase and regenerated. New species occurred in the stands, especially in their lower layer, are typical for oak-lime-hornbeam forest, such as e.g. Carpinus betulus L., Q. robur, Acer platanoides L. Rapid development of Corylus avellana L. was also observed. During last decades, the decrease in the number of Pinus sylvestris L. trees has been observed. The results of analyses of stand data in four research periods show that the wetland habitat of the Białowieża forest has been a subject to the processes of succession conditioned by environmental changes such as desiccation through lowering of the water table as well as climatic changes entailing inter alia an increase of the air temperature and a decrease of precipitation.

    Opis:
    Fragmentation of landscapes and habitats has been identified as the main driver of biodiversity loss. Ecological corridors may support the conservation of biota in fragmented landscapes due to enhanced habitat connectivity. We conducted a study in order to assess the potential of a linear woodland landscape element along a railway line as ecological corridor using carabid beetles as indicators. The results showed that for some forest species the studied woodland strip has potential as an ecological corridor. Trophy and soil acidity were most often significantly correlated with parameters and species, but width of the woodland strip and distance from the forest site were of highest importance for the formation of the whole carabid assemblages. The results of our study provide with information regarding rules for the construction of woodland strips as ecological corridors. Management strategies should integrate such areas in concepts of sustainable regional development.

    Opis:
    Łąki śródleśne charakteryzują się dużą różnorodnością gatunkową i pełnią wiele ważnych funkcji w przyrodzie [3]. Na ich terenie występuje znaczne urozmaicenie warunków edaficznych i wodnych oraz specyficzny mikroklimat [4], na co wpływa bliskość lasu, który decyduje zarówno o układzie warunków siedliskowych, jak i składzie florystycznym tych łąk [2, 4]. Poszczególne gatunki roślin obecne w runi użytków zielonych są często wskaźnikami określonych warunków siedliskowych panujących na danym terenie [11]. Dokładnej określić można warunki siedliskowe poddając bioindykacji całe zespoły roślinne [12]. Metoda fitoidykacji jest metodą obiektywną, a zarazem tańszą i prostszą w wykonaniu niż tradycyjne badania chemiczne [15]. Celem niniejszego opracowania jest scharakteryzowanie szaty ro-ślinnej porastającej wybrane łąki śródleśne oraz określenie, na podstawie wskaźników roślinnych, panujących w ich obrębie niektórych warunków siedliskowych.
    Forest meadows are characterized by high species diversity and serve many important functions in nature. On their area, there is a considerable variety of aquatic and edaphic conditions and unique microclimate, which is affected by closeness of a forest, which determines both system of habitat conditions and floristic composition of those meadows. Individual plant species present in the grasslands sward are often indicators of specific habitat conditions in the area. It can be specified more exactly site conditions using bioindication for the whole plant associations. Fitoidication method is a objective, yet cheaper and simpler in implementation method than the traditional chemical examinations. The aim of studies was to fix floristic composition of forest meadows' sward and on this basis lay down conditions of their habitats. Investigated forest grasslands were surrendered by mixed forest, situated on north of Klodawa (Lubuskie Province). There were made botanic-gravimetric analyses to stipulate floristic composition of sward and used ecological indicators values of vascular plants acc. to Zarzycki et al. [14] to appraise habitat's conditions. Estimated moisture of habitat (W), trophic status of soil (Tr), soil acidity and light conditions in communities. On this area there were floristic types with domination of Carex riparia, Phalaris arundinacea, Phalaris arundinacea with Alopecurus pratensis, Alopecurus pratensis, Arrhenatherum elatius with Festuca rubra, Arrhenatherum elatius with Holcus lanatus, Arrhenatherum elatius, Festuca ovina. On a basis of indicator species there found out that the most various were moisture conditions, characterized as from wet to dry. Soils of the largest area of investigated meadows were eutrophic with neutral to slightly alkaline pH, only soils estimated as dry were oligotrophic, and species occurred there had distinctive soil pH tolerance. There were moderate light conditions in investigated plant communities, only in community with domination of sedges recorded few species which were tolerant to partial shade.

    Opis:
    Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such plants can be a useful criterion in parks evaluation. Proposed idea of sustainable management of a park space, including selection of areas of a great ecological value, can be a chance to preserve woodland biodiversity.

    Opis:
    Three elm species are native to Poland: wych elm (Scots elm) (Ulmus glabra Huds.), field elm (U. minor Mill.), and European white elm (fluttering elm) (U. laevis Pall.). The epidemic of Dutch elm disease (DED) has led to a decrease in the popularity of elm cultivation. An analysis of forestry data was the first step in the assessment of elm resources. The area of forest stands where elms are dominant has more than doubled since 1978. Lowland alluvial forests rank first in regards to the number of elm localities per unit area of a given forest site type. While this site type is clearly preferred by elms, the majority of elm trees are actually scattered among sites of oak-hornbeam or closely related forests (of the alliance Carpinion betuli). Field research revealed a clear dominance of U. laevis, a species which in the past was predominantly located out of woodland and rarely cultivated. Data analysis indicated that all trees greater than 70 cm in diameter belonged to this species. Data from plots surveyed directly also suggest that the three elm species have slightly different habitat preferences. U. laevis prefers riparian habitats, although the major part of its resources is now on potential sites of oak-hornbeam or closely related forests. U. minor even more often than U. laevis occurs at less humid sites (mostly potential sites of oak-hornbeam or closely related forests), while U. glabra prefers moist slopes. In general, it appears that the impact of DED in the last 20–30 years has been smaller than in the preceding period, however, the disappearance of the disease has not been established. Undoubtedly, U. laevis is the elm species that is least impacted by DED

    Opis:
    The aim of the study was to recognise the species composition of beetles (Coleoptera) population occurring on hazel shrubs. Three-year studies were carried out on three ecosystems: on the cultivated hazelnut plantation, on an unprotected one and on shrubs of common hazel in the forest. The presence of 63 species was detected. The smallest number of species (22) and individuals (535) was noted in the protected plantation and the highest number in an unprotected one (46 species and 2787 individuals). In the forest the presence of 46 species and 1317 individuals was observed. The dominant species among beetles on hazel plantation in south-eastern Poland are from weevils’ family (Curculionidae). Curculio nucum and leaf-eaters from Phyllobius sp. genus were most often collected. The remaining species that were observed are non-economic pests of hazelnut, but giving up suitable chemical pest control and horticultural treatment results in an increase of their number. At that situation the number of species characteristic of common hazel growing in the forest increased on large-fruited hazel too. The species composition, number, dominance and the topic and trophic groups of Coleoptera adults are given in this paper.
    Badania dotyczące występowania chrząszczy (Coleoptera) na leszczynie (Corylus L.) prowadzono w trzech obiektach różniących się intensywnością użytkowania i warunkami siedliskowymi. Były to: plantacja leszczyny chronionej przed szkodnikami, plantacja leszczyny nie chronionej oraz krzewy leszczyny leśnej. W ciągu trzech lat badań zebrano ogółem 4639 osobników należących do 63 gatunków i 35 rodzajów. Warunki siedliskowe kształtowały skład gatunkowy i liczebność chrząszczy. Najmniej gatunków (22) i osobników (535) odłowiono na plantacji chronionej, a najwięcej (46 gat. i 2787 osobn.) zebrano na plantacji prowadzonej ekstensywnie. Entomofauna chrząszczy w środowisku leśnym charakteryzowała się zbliżonym zestawem gatunków (45) i mniejszą w porównaniu z plantacją nie chronioną liczbą osobników (1317). Na plantacjach leszczyny w południowo-wschodniej Polsce dominującymi okazały się gatunki z rodziny ryjkowców (Curculionidae). Do chrząszczy najliczniej odławianych należały gatunki arborealne, a mianowicie Curculio nucum oraz liściojady z rodzaju Phyllobius sp. Pozostałe gatunki stwierdzonych chrząszczy należy zaliczyć do szkodników nie mających znaczenia gospodarczego na plantacjach produkcyjnych leszczyny wielkoowocowej. Dopiero zaniechanie zabiegów uprawowych i pielęgnacyjnych prowadzi nie tylko do wzrostu ich liczebności, ale również do gradacyjnych pojawów gatunków charakterystycznych dla leszczyny pospolitej rosnącej w lesie.

    W pracy przedstawiono wyniki badań przeprowadzonych w trzech, różniących się pod względem opadów, latach hydrologicznych 2004/2005, 2008/2009 i 2009/2010 w zlewni śródleśnego oczka wodnego nr 1, usytuowanego na terenie Leśnego Zakładu Doświadczalnego Siemianice, w leśnictwie Wielisławice. Zlewnia badanego oczka wodnego nr 1, o powierzchni około 7,5 ha i lesistości 100%, usytuowana jest w zlewni Niesobu-lewobrzeżnego dopływu Prosny. W badanej zlewni przeważają siedliska świeże zajmując około 98% powierzchni. Od zachodniej strony oczka, w niewielkim stopniu występuje siedlisko lasu mieszanego wilgotnego. W pokrywie glebowej analizowanej zlewni dominują gleby bielicowo-rdzawe oraz brunatno-rdzawe a w niewielkim stopniu występują gleby murszaste. Natomiast przeważającym gatunkiem gleby jest piasek słabogliniasty. Przeprowadzone badania wykazały, że w suchym roku hydrologicznym 2004/2005 wystąpiły ubytki zapasów wody we wszystkich analizowanych siedliskach i osiągały one wartości od 4 mm (BMśw) do 18 mm (LMw). Natomiast w dwóch następnych analizowanych latach stwierdzono w omawianych siedliskach przyrosty zapasów wody. Największe, wahające się od 63 mm (BMśw) do 82 mm (LMw), wystąpiły w mokrym pod względem opadów roku hydrologicznym 2009/2010. Badania wykazały również, że zmiany zapasów wody w glebach analizowanych siedlisk leśnych, w półroczach zimowych i letnich omawianych lat były silnie powiązane ze zmianami stanów wód gruntowych w tych siedliskach. Współczynnik korelacji obliczony dla tych wielkości wyniósł 0,95 i zależność ta była istotna na poziomie α = 0,01.
    The paper presents the results of the researches carried out in three hydrological years 2002/2003, 2003/2004 and 2009/2010 of a different precipitation sums. The researches were carried out at catchment of water pond number one, located at Wielisławice Forestry of Siemianice Experimental Farm. The area of investigated catchment of pond number one is about 7.5 ha and its forestation totals 100%. It is situated in a part of Niesób catchment – left- side tributary of Prosna River. In the investigated catchment the predominant fresh habitats spreading through 98% area. Moist mixed broadleaved forest is located at the west part of pond. Proper podzols are predominant in soil cover analysed catchment and to a little extent there are muckous soils. Whereas predominant soil textural group there is loamy sand. The researches indicates that the decrease of water storages in all of the analysed habitats and was from 4 mm in fresh mixed coniferous forest to 18 mm in moist mixed broadleaved forest in a dry 2004/2005 hydrological year. Whereas an increase of water storages was observed in these forest habitats in the next two hydrological years. The highest fluctuations – from 63 mm in fresh mixed coniferous forest to 82 mm in moist mixed broadleaved forest were observed in wet 2009/2010 hydrological year. The researchers also showed that changes of water storages in analysed soil of forest habitat, in winter and summer hydrological half-year was connected to the groundwater levels in these habitats. The coefficient correlation was 0.95 and this relationship was significant at α = 0.01 level.

    Opis:
    The knowledge on the ichthyofauna community in forest complexes in our country is mainly limited to few information on fish species found in rivers and reservoirs located in the protected areas. Hence, the aim of present study was to evaluate the importance of forested and non−forested areas, which include small rivers, on the occurrence of fish communities. The main criteria of evaluation were species richness, biodiversity and density of fish from rivers located in forested and non−forested areas in Roztocze and Puszcza Solska (south−eastern of Poland). The 12 study sites in the two groups of small rivers located on forested and non−forested areas were chosen (tab. 1). The control fishing was performed by electrofishing using IUP−12 gear. The total of 779 individuals of fish and lamprey belonging to 22 species were caught during the study. In the sections of rivers located in non−forested areas we noted 18 species, while in the rivers in forested areas – 16 ones. The analysis of the abundance domination showed that the dominant species in the rivers sections on non−forested areas were perch, roach and gudgeon, while in rivers located in forested areas: gudgeon, dace and brown trout. Simultaneously, in abundance of fish fauna from rivers in forested area a significant share of eastern sculpin, burbot and European brook lamprey were noted. The fish communities from both habitats showed similar values of biological diversity indices, but slightly higher density was observed in the rivers located in non−forested areas. The fish species composition was highly dependent on the close surroundings of the watercourse and the type of riparian zone. For the habitats from river located in non−forested areas the common, associated with aquaculture and also invasive fish species were characteristic. However, in the rivers in wooded areas, the typical for small streams and the rheophilic fish species were more frequent. The results of present study showed, that the largest differences in the dominance in fish structure and indicators of fidelity to the habitat preferences between the groups of rivers were determined.

    Opis:
    The influence of water conditions on the condition and growth of tree stands has been analysed in the context of the climatic and hydrological functions forest plays. Long observational series obtained for precipitation, outflow and depths below the surface of the water table have been put together with measured increases in the breast-height diameters of Scots pines and the severity of crown defoliation observable in selected tree species growing on the Polish Lowland, in order to determine the overall scope to the reaction stand condition manifests in the face of ongoing variability of water conditions within forest. An overall improvement in the condition of stands over the last 20 years does not disguise several-year cyclicity to changes capable of shaping the situation, i.a. departures from long-term mean values for precipitation totals and groundwater levels. The condition of stands is seen to worsen in both dry and wet years. Analysis of the degree to which pine, spruce and broadleaved stands experience defoliation points to spruce stands responding most to extreme hydro-climatic conditions. Extreme situations as regards water resources were seen to involve a response over two-year time intervals in the case of coniferous stands. Unsurprisingly, optimal growing-season (June-September) precipitation totals correspond with long-term average figures, while being slightly higher for spruce (at 384 mm), than for Scots pine or broadleaved species (375 mm). The relationships reported gain confirmation in analysis of periodic change in breast-height diameter increments characterising Scots pines, whose growth is seen to depend closely, not only on precipitation, but also above all on the depth of the water table in the summer half-year. Optimal depths of the water table proved to be different, being around 20 cm below ground in the case of marshy coniferous forest, 80 cm in wet habitats, and 135 cm in fresh habitats. Depending on the possibilities for water to soak into the rooting zone of trees there were even twofold differences in measured growth increments in Scots pine (as the dominant species in Poland’s lowland habitats). The maintenance of stable water conditions (as the most variable environmental factor in forest) should be an overriding aim of management activity in this habitat. When account is taken of the influence of the state of water resources on biomass production, and then on the intensity of evapotranspiration and the absorption of carbon dioxide from the atmosphere, it is seen how important it is to achieve improvements in water conditions in forests, as such an important factor in combating climate change.

    Opis:
    Scots pine (Pinus sylvestris L.) is economically the most important tree species in Polish forestry. Congeneric pine stands have a quite low level of biodiversity, and logging with clear sites may even cause their further decline. It is very important to discover the influence of clear−cuttings in managed pine stands on different groups of organisms. One of them are bats which play an important role in forest biotopes as a regulator of insect pests. The aim of this paper is to compare the foraging activity of bats in pine stands of different stages of growth. The study was carried out in three complexes of pine forests in western Poland: Drawska Forest, Notecka Forest and Dolnośląskie Forests. Four types of growth phases were studied: clear−cut sites (Z), young plantations in the age 2−5 years (U), 41−60−years−old stands (III) and mature stands in the age over 80 years (V). The study of the foraging bat activity was conducted with broadband ultrasound detectors Pettersson D−1000X within 3 hours after sunset in summer periods of 2013 and 2014. The recordings were analyzed with BatSound software. Total 19 180 bat passes were recorded on all 120 sampling plots. 11 bat species: Nyctalus noctula, Pipistrellus pipistrellus, Eptesicus serotinus, P. nathusii, Myotis myotis, P. pygmaeus, M. nattereri, Barbastella barbastellus, N. leisleri, E. nilssonii and Vespertilio murinus and four groups of species: NEV (Nyctalus, Eptesicus, Vespertilio), MSP (Myotis), PSP (Pipistrellus), and PLE (Plecotus) were recognized (tab. 1). The dominant was common noctule N. noctula (71.5%). The highest foraging activity of bats was recorded in open areas: clear sites and plantations (fig. 1), next in mature stands and middle−aged stands. The obtained results suggest that bats can adapt to a mosaic of habitats created by clear−cutting harvesting system in managed pine forests.

    Opis:
    The study focuses on capercaillie (Tetrao urogallus) and other Galliformes birds reintroduction projects carried out in Europe since the 1950s. In Germany alone, there have been eleven projects involving the release of a total of ca. 5,000 caprcaillies, mainly obtained from the closed breeding centres. The majority of birds died shortly after release. The high mortality was caused by great pressure from predators and the poor adaptation of the birds bred in captivity to the wild−life conditions. The high mortality among the birds from artificial breeding is associated with changed morphology (e.g. shorter digestive tract, less−developed pectoral muscles), physiology, and behaviour (insufficiently developed social and anti−predatory behavioural mechanisms). Survival rates among the birds released into the wild were primarily affected by the method of breeding and release, quality of habitat, and pressure from predators. The survival rates of translocated birds were higher than those obtained from traditional breeding in aviaries. Better results were also obtained with the 'born to be free' method of breeding and release based on social contact between the mother and chicks. The following actions are obligatory in reintroduction projects: predators reduction, evaluation and improvement in the quality of environment, as well as long−term monitoring of birds. The factors crucial for the effectiveness are: the total number of birds released, the number of released birds in subsequent years, and the overall duration of the project.
