    forest habitat
    trophic soil index
    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:
    Forestry management in anthropo−transformed habitats is characterized by a very high risk. The formation of waste as well as flooding of tree stands by salty water from different sources of mining and processing of coal is an important issue on the industrial areas. The introduction of the pollution load in the form of saline water leads to increased soil salinity, which can damage or cause the dieback of individual trees, tree stands and whole forest ecosystems. The aim of the research was to (i) analyze the changes in forest soils on the area flooded by water leaked from the waste reservoir, (ii) assess the possibility of this soil self−purification from chlorides and sulfates and (iii) estimate the possibility of reclamation of this land for forestry purposes. The study was conducted in Katowice Forest District (southern Poland). Soil samples for physico−chemical analysis were collected in 2015. The results of chemical analyzes of surface soil layers made in 2013 and 2014 were also used. The content of chlorides and sulphates in the soil was used as one of the key indicators to assess the level of soil salinity. In the year of the damage occurrence, in surface horizons it significantly exceeded the threshold value, but declined in subsequent years to a level below this value even in the area of the greatest damage. However, our analysis indicate an accumulation of chlorides and sulphates in the soil at a depth of 100−120 cm, as well as the accumulation of sodium cations. This demonstrates the difficulties with the self−purification of soil or continuous supply of pollutants from the waste reservoir. Currently, surface soil horizons meet the criteria of not−salinized soils, which does not indicate a need for change in land use. After the surface preparation and technical work used in forestry practice, the damaged area can be designed for the reintroduction of forest trees.

    Opis:
    The objective of the study was to determine the impact of selected soil properties on site index of oak (Quercus sp.) stands in the Międzyrzec Forest District (eastern Poland). We utilised data from the soil−habitat survey, which provided information about physical and chemical properties of soils and stand descriptions for 21 oak stands (tab. 1). The collected data served to determine site index (SI), defined as the stand top−height at the age of 100, and soil trophic index (SIG) that is a synthetic measure of the soil fertility. For SI and SIG distributions met the criteria of the normal distribution (Shapiro−Wilk test p−values equalled 0.118 and 0.297, respectively), we applied one−way analysis of variance, t−test and correlation analysis to determine the influence of the forest habitat type and moisture as well as soil properties and fertility measures on the site index of analysed oaks. The SI of investigated oaks ranged from 23.2 to 29.3 m, 26.5 m on average (tab. 2). It was significantly dependent on the site type (F=6.913, p=0.006) with the lowest values on oligotrophic habitat and the highest – on eutrophic one. No effect of habitat moisture content and soil type was found (t=–0.408, p=0.688 and F=2.599, p=0.076, respectively). The SIG values ranged from 20 to 36, with the average of 29.5 (tab. 2). Similarly to the site index, we found significant impact of the forest habitat type (F=5.384, p=0.015) on SIG values. Soil fertility and physical properties significantly influenced site index of the analysed oaks (fig.). We found positive correlation between SI and SIG values (r=0.566, p=0.007) as well as between SI and clay content (r=0.454, p=0.037). Chemical properties of the soils under studied stands seem to have less profound effect on site index of oak. The highest, but insignificant, correlations were found for recalculated acidity (r=–0.420, p=0.056) and magnesium content (r=0.400, p=0.071).

    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:
    The objective of the research was to assess the soil structure parameters (the index of cloddiness, of pulverization, of soil structure and the mean weighted diameter of soil aggregates – MWDa), as well as the selected chemical soil properties (pH, the content of organic carbon, total nitrogen and available potassium and phosphorus) in the three urban forests in Wrocław (SW Poland) depending on the occurrence of tree species (Quercus robur, Fagus sylvatica, Carpinus betulus). Soil samples were collected under the crown of each tested tree taxons, from three different sites, in three replications, separately in every forest. The soil was taken from two layers: 0−20 cm and 20−40 cm. The structure and weight of mechanically solid soil aggregates were determined using dry separation method. The content of total nitrogen was determined with Kjeldahl method, while phosphorus and potassium – with Egner−Riehm method. Organic carbon was determined with the use of elementary carbon analyser Behr C−50 IRF. The pH was determined by poten− tiometric method in 1M solution of KCl. The results were statistically analysed using the ANOVA. The correlation coefficient between the mean weighted diameter of soil aggregates and the content of organic carbon in the soil was calculated. The tree species occurring in the urban forests of Wrocław affected the soil structure parameters as well as changed the chemical properties of the soil. In both Mokrzański and Rędziński Forests the significantly higher index of soil cloddiness was observed under hornbeam crowns than in the oak and beech surroundings. In the Osobowicki Forest the highest index of cloddiness was determined on the soil with the oak. In general, higher values of index of soil structure and the mean weighted diameter of soil aggregates were noticed for the hornbeam sites than the oak and the beech ones. There was a significant positive corre− lation between the MWDa and the content of soil organic matter (r=0.711, Y=0.4569·x+1.6523). The differences in the content of organic carbon depending on tree species were observed in the Rędziński Forest, while in content of total nitrogen also in the Mokrzański Forest. The highest content of organic carbon and nitrogen was noticed in the soil under the hornbeam. The species of trees affected the content of phosphorus and potassium in the soil, but there was no unambiguous direction of changes.
