Opis:
Concentration and profile distribution of heavy metals was investigated as contamination indicators of the forest soils formed from glacial deposits of the South Podlasie Lowland. The study was carried out on thirteen soil profiles situated a hundred meters from the road. The highest content of heavy metals was found in the organic horizons of the investigated soils. The mean content of Mn, Zn, Cu, Pb, Ni, Cr in the investigated soils were: 556.7, 72.9,15.5, 63.5,13.8, 16.5 mg/kg d.m. of the soil, respectively. In the mineral-organic and mineral horizons of the investigated soils heavy metals were present in quantities which were close to natural. The podzol soils, podzols and rusty soils developed from sands contain less heavy metals than the soils lessivés, black earth and deluvial soil. The Mn, Zn, Cu, Pb distribution in the soil profiles is influenced by the soil forming processes. The distribution index of the examined metals distribution in the genetic horizons testify to it.

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 author investigated a 0-3 cm layer of two forest brown soils: brown acid and brown leached. These forest soils were under handsome beech trees (Fagus sp.) between 100 and 120 years old. The author compared the chemical properties of the soils. The soil existing near the tree trunk (1 m2 of surface, strongly washed by rain water polluted by chemical substances) and the soil existing under the tree umbrella (40 m2 of surface in the area of the tree-tops, washed poorly by rain water). This comparison showed changes in these properties, dependent upon the degree of atmospheric contamination. It was found that, at the same level of atmospheric contamination, higher changes of properties were found in brown leached soil than in brown acid soil. Less acidified soils (with alkaline or neutral pH reaction) are more suitable in these researches. The investigations of the forest soil layer 0-3 cm (12 soil profiles) showed that changes in their chemical properties in relation to tree trunk-tree umbrella can be the basis of assessment of the degree of atmospheric contamination.

Opis:
Studies on the soils in forest ecosystems in breaks of the rivers Jeleń and Sopot were carried out in the years 1997-1998. Although the rivers differ in length, catchment area, amount of water carried and breadth of the valleys, the most important factors affecting soil formation and their spatial differentiation are similar: bedrock, relief, water drainage, natural type of water management, position of the ground water-table relative to the river water level, and chemistry of spring and soil waters. Steep slopes of the valleys covered with poor and highly acidic podzolic soils are usually overgrown with fir and pine phytocenoses, or rarely, with mixed oak-pine forests. The bottoms are often characterised by longitudinal duality of the flood-plain benches. In the drier area close to the river beds under ash-alder forests, there are more fertile gley soils and gley podzols. Poorer and more acidic localities are occupied by mixed forests with spruce. In permanently moist fragments of the benches at the foot of the slopes and in depressions with stagnant water weakly acidic peat-mud and peat soils occur overgrown with bog-alder forests. Peculiarities of these areas are low peat-bogs suspended even up to 4-6 m above the water-table of the river.

Opis:
Natural variability of pseudogley forest soils in the Białowieża National Park was characterised on the basis of five soil exposures. Two of them were located in a water-logged site, one in a mound one in a patch with dominance of deciduous trees, and one in a spruce biogrup. It was found that pseudogley soils of a natural moist deciduous forest show additional differentiation in the form of characteristic micromosaics. There is a pronounced impact of the species structure in a treestand, uprooted trees and hoofed mammals on the properties of the soil cover. Changes resulting from the above biotic factory were observed in all the analysed physical, physico-chemical and chemical soil parameters.

Opis:
The aim of this paper was to assess differentiation in the total content of Cu, Zn and Mn under the influence of water erosion. The present author investigated parent material, eroded soils and delluvial sediments of a small arable-forest catchment of the moraine zone in West Pomerania. The average content of heavy metals in the parent rock (boulder light loam) were assumed as geochemical backgrounds of Cu, Zn and Mn. It was found out that erosion process caused differentiation in heavy metals. Zinc was the most mobile in this transportation; Mn was not sensitive to it. Delluvial sediments from arable (drainage) depressions had a clearly lower content of Cu and Zn than the parent material. It was also noted that Cu and Zn content in the forest area was lower than in the arable area of a similar relief and soil composition. Mn content was always higher in the arable soils. Soil-forming processes influenced differentiation of heavy metals in the vertical soil profile. The humus and Bt horizons (accumulation of silicate clay) were enriched with heavy metals. A decrease of heavy metal content was noticed in the eluvial horizon (Eet - outwash of silicate clay). The humus horizon of the investigated soil had, a natural (not increased) content of Cu, Zn and Mn.

Opis:
This paper presents pedological research in Žutica forest in northern Croatia. The most common soil types found in this area belong to the hydromorphic class (Pseudogley, pseudo- gley-gley, eugley, fluvisol) except technogenic soils formed as a result of intensive oil exploitation. Some main chemical and physical characteristics of soils are given. For forest productivity the most productive combination of soils are hypogley and pseudogley-gleysol and minimal productivity is in heavy amphygleic soils. An increase of heavy metals occurs in flooded soils in Žutica from nearby agricultural land. A high concentration of active phosphorus,and nitrogen can verify the influence of field fertilisers on the forest. Levels of cadmium found in technogenic soils exceed the permitted concentration. A large amount of CaCO3 in relation to natural forest soils can be found in technogenic soils because of quick lime disposal after oil spills and also pH increase and a nutrition and humus decrease.

Studies considering hummocks and hollows structure of bog forests were carried out in the Stare Biele Reserve in the Knyszyn Forest. The aim of the study was better recognition of bog forests spatial structure including recognition of soil chemical composition of hummocks and hollows. The bog forest communities in Stare Biele Reserve have various percentage of hummocks. The hummocks have similar morphological structure and are distinctly separated from hollows in all four bog forest communities. Degree of hummocks development and their morphological structure have big impact on plant distribution on their surface. Soil chemical properties are one of the factors, which influence floral abundance and composition of microcenoses. Soil reaction and calcium content, among other measured properties, exert the biggest influence on the floral abundance and composition of microcenoses.

Mountain forests are facing substantial changes. The need to adapt forest management to climate change is overlaid by the consequences of demographic changes that alter the form of land use profoundly. The European policy is aware of the challenges and supports mountain regions by the Regulation for Rural Developments and other strategies. Regional efforts of the Forest Authorities account for the changing ownership structure in order to ensure sustainable forest management and the provision of the dependent ecosystem services.

Opis:
The aim of the studies carried out in the natural oak-hornbeam forest Tilio-Carpinetum typicum and in the degenerated form in the stage of pinetization Pinus-Lamniastrum, was to obtain and compare qualitative-quantitative structures of soil fungi communities in two different oak-hornbeam forests. This degenerated form of oak-hornbeam forest is the result of removing the natural tree population (typical oak-hornbeam forest) and re-afforesting the resultant vacant area with pines. The study plots were located in such a way that the variations of soil fungi communities were affected only by seasonal changes in the vegetation of the degenerated oak-hornbeam forest Pinus-Lamnias- trum. The soils in both study plots are typical forest grey-brown podzolic soils (Luvisols). The results of mycoiogical studies indicate significant differences between soil fungi communities in both oak-hornbeam forests, although similarities especially in species composition of 15 of the most abundant fungi species were also found. The differences are the result of changes in the floral composition of degenerated oak-hornbeam forest. In the past, when typical oak-hornbeam forest covered whole studied areas, the soil fungi communities were probably almost the same in both plots. The first change could have happened after the removal of the trees; the second, after the re-afforestation of the resulting vacant area with pines. The re-appearance of Tilio-Carpinetum typicum in its once occupied habitat causes changes in the soil fungi community in the degenerated oak-hornbeam forest.

Opis:
Large spore mushrooms and trees are frequently used in bioindication, the reasons being their widespread occurrence and substantial capacity to accumulate trace elements. The aim of the research was to compare the bioaccumulation coefficients of As, Ba, Al, and Cr in Lactarius salmonicolor L., and in Abies alba M. needles, collected in the Przedbabiogórskie Mountain Range. In 2015, samples of soil, mushrooms and Abies alba needles were collected from 17 sites. All the collected samples were dried and homogenized. Laboratory samples of the mushrooms and needles were subjected to dry mineralization in an open system. The soil samples were mineralized in aqua regia. Concentration of elements in the solutions was determined by atomic emission spectrometry. Based on the results, bioaccumulation factors of individual elements were calculated. The bioaccumulation factors were calculated by dividing the concentration of a given element in the dry matter of mushrooms and needles used in the research by the content of the same element in the soil. In addition, the correlation coefficient between the content of the above elements in the soil, mushrooms and needles was computed. The content of the elements in forest soils was low, typical for unpolluted areas. Concentrations of the elements in Lactarius salmonicolor L. and in Abies alba M. needles were in the following decreasing order: As>Cr>Ba>Al. The values of bioaccumulation factors of the elements in needles can be arranged from the lowest as follows: Al>Cr>As>Ba, whereas in the mushrooms the order was Al>Ba>Cr>As. No statistically significant relationship between the organic carbon content in the soil and the level of accumulation of the elements in the fungal fruiting bodies and fir needles was observed. The content of elements in the soil had the largest effect on the amount of these elements accumulated in Abies alba needles and in biomass of Lactarius salmonicolor.

The aim of the work was to investigate various soils properties in the partial forest reserve "Krzywiczyny", in the Namysłów Forest Inspectorate (Opole Voivodeship). It was found that upper soil horizons, including organic, humic and illuvial ones, indicated clear accumulation of Mn, Zn, Cu, Pb and Cd. However, a tendency to diminution of these elements content with profile depth was noted. High positive correlation was stated between organic matter content and Mn, Zn, and Cu amounts in the brown leached soils studied.

Opis:
The paper provides a detailed characterisation of Norway spruce stands in the Ukrainian Carpathians. The majority of natural spruce stands in Ukraine occur in Polesie, while artificial regeneration is spread all over the country. The most densely forested part of Ukraine is the Carpathian region with 41.1% of forest-covered area (2.1 million ha). Spruce-dominated stands occupy about 700 thousand hectares (30%) of the forested area of the state forest fund in the Ukrainian Carpathians, and another 10% of the mixed forests contain 10 to 30% of spruce. Besides pure spruce stands, there are beech-spruce, beech-fir-spruce, and cedar-spruce stands. The most productive stands (750-900m3 stem wood per ha) grow in the middle and lower parts of slopes at 1100-1200 m a.s.l. which have favourable soil and climate conditions. Since the second half of the 20th century, spruce stands in the substantial part of the Ukrainian Carpathians have declined under the influence of complex anthropogenic and natural factors. Although the present condition of most spruce forests in this region remains satisfactory, the degradation processes and the ban imposed in 2006 on planting spruce on non-spruce forest sites (in state forests) may decrease their area in the longer term.
