Bialowieza Forest
Opis:
The study concerned changing status of water retention within an unique nature complex of the Białowieża Primeval Forest. The retention was evaluated based on an analysis of research results on water outflow from the lowland catchment of the river Łutownia – representative for physiographic conditions as well as those of habitats and tree stands in Poland’s part of the Forest. The catchment in the lowland hydrometric dissection at the Pogorzelce village – Old Białowieża Wilderness, covers the area of 120.1 km2 with natural flow conditions preserved. A unified sequence of measurements carried out since 1966 using unchanged methodology with respect to precipitation, air temperature and forest management status allowed to separate different phases of changes occurring in water resources of this protected forest complex. There were appraised periodical runoff changes and cycles including a decrease in water resources which occurred at the turn of the century. The retention capacity of the catchment was determined based on periodical changes in rainfall-runoff relations and the ongoing process of deteriorating water conditions of forest ecosystem was interpreted.

Opis:
Amongst various and diverse organisms, earthworms (Annelida: Oligochaeta) are the most important components of soil biota when it comes to soil formation and maintenance of soil structure and fertility. The presence of earthworms modifies the soil quality of the environment due to their burrowing and casting. This affects the activities of other organisms. Thus, they are also termed “ecosystem engineers”. However, while we begin to understand the role of surface casts, it is still unclear to what extent plants utilize subsurface casts. This work is a study of the floral community structure as influenced by surface cast so as to determine the functional groups of earthworms in the natural forest zone of Onigambari Forest Reserve. This reserve is located at latitude 07°25’N and longitude 3°53’E within the low and semi-deciduous forest belt of Nigeria. It is divided into two: natural and plantation forests. Herein, the simple random sampling technique was used to select 10 geo-referenced plots (15m × 15m each). Three 1.0m × 1.0m square quadrats were randomly laid on each plot to give 30 sampling points surveyed for data collection. Data were collected on floral composition, relative importance values (RIV), earthworm composition and diversity, and physicochemical components of the soil. Twenty eight herbaceous plants were enumerated. Andropogon gayanus had the highest relative importance value (RIV) of (20.499), while Acroceras zizanoides and Platostoma africanum had the least RIV (1.1782) amongst other four. Seven earthworm species were enumerated, with Eisenia fetida having the highest RIV (28.571), while Octoclasion cyaneam and Lumbricum rubellus had the least. The species richness of earthworms was high (0.8061) and evenly distributed (0.8405), but with a low diversity (H’ = 1.772). There are two functional groups of earthworm in the natural forest zone, seven were surface dwelling, while only Lumbricus terrestris was sub-surface dwelling. The health of flora and soil of the natural forest zone of Onigambari forest reserve is low. Prevention of outside influence on the forest zone, seeding and deposition of organic waste matter to the soil are strategies that would enhance abundance and diversity of earthworms in the natural forest zone.

Opis:
The article describes horizontal structure of the tree layer, natural regeneration, snags and crown projections of natural beech stands on three permanent research plots in the wide altitudinal range in the Krkonoše Mts (Czech Republic). The spatial structure was classified from 1980 to 2010 and subsequently the prediction of spontaneous development with an outlook for 30 years (to 2040) was done by growth simulator. Hopkins-Skellam index, Pielou-Mountford index, Clark-Evans index and Ripley’s K-function were calculated. Further, the vertical structure and total diversity index was evaluated. The horizontal structure of individuals in the tree layer had not changed significantly during the monitored years. Tree spatial pattern of the lowest altitude lying herb-rich beech forest was mostly regular to random, in acidophilous mountain beech forest predominantly random and in fragments of beech groups around the timberline aggregated. Juvenile growth on all investigated plots was distributed aggregated and snags randomly. The horizontal structure of crown projection centroids had always higher values toward the regularity than tree layer and was random to regular. The result of principal component analysis also confirmed that spatial pattern was dependent on the altitude, but also on the number of trees.

Opis:
The study deals with long-term dynamics of snags and fallen dead wood from 1970 to 2010 in an unmanaged forest ecosystem dominated by European beech in the Bažinky area, Krkonoše National Park (Czech Republic). The volume of dead wood was estimated from 1970 separately for fallen dead wood (logs) and standing dead wood (snags and stumps). Total dead wood volume on permanent research plot (PRP) 6 increased from 41.9 to 241.6 m3 ha–1 and on PRP 7 from 27.7 to 170.0 m3 ha–1. During 40 year case study the mean total volume of fallen dead wood was 193.3 m3 ha–1 (± 29.8 S.E.) and 96.2 m3 ha–1 (± 19.4 S.E.) and the mean total volume of standing dead wood was 17.4 m3 ha–1 (± 3.4 S.E.) and 12.6 m3 ha–1(± 1.4 S.E.) on PRP 6 and PRP 7, respectively. Comparing tree species, the mean volume of fallen dead wood was significantly higher for Norway spruce than for beech in the decomposition class 1 (F(1, 14) = 5.7, P = 0.03) and significantly higher for beech in the decomposition classes 4 (F(1, 14) = 20.4, P < 0.001) and 5 (F(1, 14) = 25.5, P < 0.001). Dead wood was distributed from randomly to aggregated spatial pattern. Despite the rapid decay of beech wood, the amounts of deadwood are likely to increase further during the next decades with continuing disintegration of the forest stand.

Opis:
Five plots with young beech trees of the same age (13–15 years) were established to study the threshold, where plagiotropic growth becomes evident as the consequence of the reduced light intensity. Trees were equally distributed along the light gradient and were divided according to light conditions (Indirect Site Factor, ISF) into three groups of stand conditions: close canopy stand (ISF<20), edge (2025). Morphological and physiological responses of young beech were studied between managed and old growth forest and between different forest complexes (Pohorje and Kocevje region) on natural beech sites. Criteria for the plagiotrophic growth was the relation between tree length and tree height (l/h) under various light conditions. Under controlled conditions (temperature, flow and CO2 concentration, RH, light intensity) light saturation curves of leaf net photosynthesis were measured on same trees to compare both responses between different light categories and different plots within comparable light conditions. Our study confirmed different thresholds for morphologic response between two forest complexes as well as between old growth and managed forest. Results were in accordance with physiological responses: the value of limiting light for a plagiotropic response was lower in Kocevje (17% ISF) than on Pohorje (25% ISF).

Opis:
The present research deals with carbon sequestration, as an important process for mitigating the effects of climate change. The investigation focuses on a 30-year period and it covers only aboveground biomass that builds up from natural forest regrowth, excluding any plantation techniques. Potential carbon sequestration rate from natural forest regrowth in Godech Municipality was measured in Mg C ha⁻¹ yr⁻¹ and the resolution of the map was 1x1 km. The results of the study display that carbon accumulation values in the researched area were consistent with those that were expected in the largest parts of Bulgaria. The biggest share of Godech Municipality falls within the range of 0.82 – 0.96 Mg C ha⁻¹ yr⁻¹ with restricted areas around the villages of Barlya, Smolcha, Gubesh, Murgash and Varbnitsa that may accumulate between 0.96 – 1.11 Mg C ha⁻¹ yr⁻¹. In conclusion, carbon accumulation only from natural forest regrowth provides representative information, however it would have been better if different plantation techniques were regarded as well. The successful results of the investigation should encourage other studies of this type in the neighbouring municipalities.

Opis:
Funkcje gleb silnie zależą od aktywności mikroorganizmów i ich zdolności do przeciwstawiania się różnym stresom środowiskowym. Celem pracy było porównanie wpływu dwóch często występujących czynników stresowych – cykli susza-wilgoć i mrożenie-rozmrażanie – na respirację gleb industrioziemnych i gleb naturalnych. Próbki gleby (n = 18) zostały pobrane na zrekultywowanych terenach kopalni piasku w Szczakowej oraz w lasach naturalnych w jej sąsiedztwie. W próbkach oznaczono zawartość materii organicznej, tempo respiracji, pH i przewodność elektrolityczną. Badane próbki z gleb industroziemnych i naturalnych miały podobne uziarnienie i zostały sklasyfikowane jako piaski gliniaste. Gleby naturalne zawierały znacznie więcej OM [%] niż gleby industrioziemne, natomiast obie rozpatrywane kategorie gleb nie róż- niły się znacząco pod względem pH. Ponadto nie zaobserwowano istotnych różnic w zawartości materii organicznej, pH i uziarnienia gleb w próbkach pobranych pod różnymi drzewostanami (sosna, brzoza, modrzew). Gleby industroziemne wykazywały znacznie niższe początkowe wartości respiracji (1,34 μg C-CO2 g−1 24 h−1 ) niż gleby naturalne (3,13 μg C-CO2 g−1 24 h−1 ). Pięciocyklowy proces mrożenia-rozmrażania zredukował skumulowane wartości wydzielania CO2 zarówno w industrozimenych, jak i naturalnych glebach o odpowiednio 17,8% i 6,7%. Ponadto reakcja na wskaźnik respiracji w cyklu susza-wilgoć różniła się znacząco w przypadku gleb industroziemnych i naturalnych: w glebach naturalnych wszystkie cykle suszenia-nawadniania zwiększały wartość respiracji, przy czym wzrost ten był bardziej widoczny w ostatnich dwóch cyklach. Podsumowując, można stwierdzić, że okresy suszy w lecie i mrożenia-rozmrażania jesienią oraz wiosną mogą wywierać bardziej negatywny wpływ na leśne ekosystemy na ternach zrekultywowanych niż na obszarach występowania naturalnych drzewostanów.
The functioning of soils strongly depends on the activity of the soil microbial communities and their ability to withstand different environmental stresses. The aim of this work is to compare the effect of two frequently occurring stressors (drought-rewet and freeze-thaw cycles) on the basal respiration rate of mine and natural soils. Soil samples (n = 18) were delivered from the Szczakowa open-cast sand quarry in Poland. The samples were measured for organic matter (OM) content, basal respiration, pH levels, and electric conductivity. The studied mine and natural soils had a similar texture and were classified as loamy sands. The natural soils contained significantly more OM than the mine soils but did not differ in terms of pH. There were no significant differences in the OM content, pH, and texture of the soils under the studied tree species (Pine, Birch, Larch). Mine soils exhibited significantly lower initial respiration rate (RESP value) than the natural soils (1.34 μg C-CO2 g−1 24 h−1 vs. 3.13 μg C-CO2 g−1 24 h−1 ). Five freeze-thaw cycles reduced cumulative CO2 evolution both in both the mine and the natural soils by 17.8% and 6.7%, respectively. Moreover, the reaction of the respiration rate to dry-rewet cycles differed distinctly between the mine and natural soils. In the natural soils, all dry-rewet cycles increased the respiration rate, wherein the increase was much more pronounced in the last two cycles. We conclude that periods of drought in the summer and freeze-thaw events in the autumn and spring may have a stronger negative effect on the functioning of forest ecosystems in the reclaimed lands than in natural stands.

English yew (Taxus baccata L.) is a rare tree species in Austria and gene conservation forests reserves are used to maintain English yew populations by silvicultural treatments. This paper describes the current situation of an English yew population at “Stiwollgraben”in Austria with regard to stand structure, vitality and natural regeneration. The area is one of the most important sites in Austria as it consists of 2236 yews.The vitality condition of the yew is very good, and more than 79% of the yews have been assessed as very vital to vital. The potentiality for natural regeneration (13019 one-year seedlings ha–1) is very high, but not all height classes are represented. This indicates a high survival ability of English yew at this site. Three different treatment strategies are described to maintain the yew population. The future effects of these treatments are discussed in the light of the environmental requirements of English yew.

Activities of radioisotopes were measured in samples of forest soil. The samples were collected in forests situated along the roads from Złoty Stok (Poland) to Hradec Králové (Czech Republic). Each soil profile was separated into individual horizons and subhorizons. Activities of radioisotopes were measured in the sample of each soil horizon. Activities of the following radioisotopes were determined by gamma-ray spectrometry: 214Pb, 214Bi, 231Th, 235U, 212Pb, 212Bi and 228Ac. Distributions of the data concerning radioactivities were positively skewed. The lowest activity was found for 235U (median value was 2.25 Bg/kg) and the highest one for 228Ac (16.26 Bg/kg in median). In organic horizons activities of radionuclides were lower than in organic ones. Interrelation between activities was examined using ordinary and robust regression methods. It was found that activities of the radioisotopes were well correlated.

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

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

This research is aimed at determining the health condition and productivity of Scots pine (Pinus sylvestris L.) stands created during 1906–1908 on the initiative of Prof. V. D. Ogievsky. The scheme of silvicultural experiments included: determining the influence of different widths and directions of clear felling on the natural regeneration, testing of pine plantations of pure and mixed composition and the choice of methods for their creation. In terms of health condition, 103–105-year-old artificial pine stands are weakened and their health condition is slightly worse compared to the aged pines of natural origin. The productivity of age-old linden-pine plantations is higher than of pure pine plantations, and the stock of stem wood in plantations created by seed sowing and marketability is higher compared to the plantations created by planting seedlings.

Fires in natural ecosystems cause catastrophic consequences on a global scale. These fires are caused by landscape-transforming factors, which include dust and gas pollution of the atmosphere, destruction of forests and living organisms, pollution of ecosystems with dangerous toxic compounds and heavy metals. The aim of the presented research is to investigate the influence of ground forest fires on the concentration of mobile forms of heavy metals in different soil horizons. Sampling of soils of pyrogenic origin was carried out from 4 plots according to operating standards on the territory of Rava-Rusky forestry near the village of Lavrykiv, Zhovkva district, Lviv region (Ukraine). Soil sampling for investigation of migration of heavy metals was carried out taking into account the number of years spent after burning of meadow vegetation and forest litter. The most contaminated with heavy metals is site #2 (completely burned out 2 years before the experiment). There is a significant accumulation of cadmium in edaphic horizons (0.31 – 0.66 mg/kg), the value is close to the maximum allowable concentrations for soils (0.7 mg/kg). Also in this area the highest content of mobile forms of nickel (1.52 – 2.80 mg/kg) was detected, while the maximum allowable concentrations for soils is 4 mg/kg. The lowest content of heavy metals is in the site #1, which was exposed to fire long before the start of monitoring – 3.5 years. Here the values of mobile forms of heavy metals are close to the background. Vegetation in burnt areas at the first year of post-pyrogenic development is characterized by spontaneous single species. In 2–3 years it is characterized by a group arrangement. Complete natural overgrowth of the burnt area (natural vegetative reclamation) occurs 4–5 years after combustion. Monitoring the impact of ground forest fires on the concentration of heavy metals in edaphic horizons is important in terms of environmental renaturalization and the development of preventive measures for forest fires and fires in natural ecosystems.

Opis:
The focus of the present study are valuable natural areas, and its purpose is to present the beneficial effects of the forest environment in these areas on the human body. The study has analysed the results of research by various, mainly foreign, authors concerning the treatment of the forest environment in Poland referred to as “forest therapy”, “sylwotherapy.”Research has shown that being in a forest environment helps to preserve mental balance, strengthens the immune system and stimulates organism’s regeneration. Differences in the impact of different types of forests were also observed. Pine forests calm down, lower blood pressure and help the respiratory system. Broadleaved forests stimulate, improve mood and enhance the ability to concentrate by affecting various aspects of human life. The results of the analyses show that in Poland the interest in forest therapy could be another form of raising public awareness by informing people how important is the role of the forest, not only in nature but also for human health.

Materiały i metody: W pracy przeanalizowano wyniki badań różnych autorów, głównie obcojęzycznych, dotyczących leczenia środowiskiem leśnym, w Polsce zwanym lasoterapią, sylwoterapią. Wyniki: Badania udowodniły, że przebywanie w środowisku leśnym pozwala zachować równowagę psychiczną, wzmacnia układ odpornościowy i pobudza organizm do odnowy. Zaobserwowano również różnice w oddziaływaniu poszczególnych typów lasów. Bory sosnowe działają uspokajająco, obniżają ciśnienie i wspomagają układ oddechowy. Liściaste grądy działają pobudzająco, poprawiają nastrój i wspomagają zdolność koncentracji oddziałując na różne aspekty życia człowieka. Wnioski: Wyniki analiz ukazują, iż w Polsce, zainteresowanie lasoterapii mogłoby stanowić kolejną formę dotarcia do świadomości społeczeństwa z informacjami, jak ważną rolę pełni las, nie tylko w przyrodzie, ale także dla zdrowia człowieka.

Opis:
Ash dumps occupy significant areas around the world and make a negative influence on the environment. This effect is decreased by their natural colonisation determined by the bioclimatic conditions of the area. The purpose of the current study was to identify the structure of the forest communities and the initial stages of soil formation on the ash dump in southern taiga. This study was carried out on three sites in the forest phytocoenosis formed in the process of revegetation of the Verkhniy Tagil Power Station ash dump over 50 years, as well as on two background forest sites in the Middle Urals. Complex geobotanical and soil studies were carried out. The results of the study show that forest phytocoenoses with a predominance of hardwood species (Betula pendula Roth and Populus tremula L.) and a small admixture of coniferous species can form on the non-recultivated ash dump within 50 years in a boreal zone. In total, the studied mixed forest phytocoenoses are similar in composition to zonal secondary forests, but differ by having lower height and diameter of the stand, as well as herb–shrub layer coverage. Their species density and floristic richness are also lesser. The study proved that the process of soil formation is also proceeding according to the zonal type in the ash substrate under forest communities. The results of the study can be applied to justifying the forecasts of ecosystem restoration on the technogenic substrate, as well as for the species selecting for their recultivation in the studied area and similar to it.
