Opis:
The objective of the paper was to determine the size structure of the canes and individuals of Rubus hirtus populations and compare them with regard to the type of soils developed on different geological substrates (granodiorite partially covered by boulders, weathered rocks, river sediments, loams and rock rubble for podzolic soil; limestone and conglomerate interlayers for humus−rich and brown rendzinas and on Carpathian flysh for acid brown soil). The mean Rubus hirtus density on all study sites significantly differed from each other. The highest ramet density (11 individuals/m2 ) was noted on the "Dolina Łopusznej" site, while individuals from the populations on the remaining study sites occurred locally in smaller or larger clusters. The shoots of Rubus hirtus growing on podzolic soils significantly differed from those growing on acid brown soil. Long shoots (over 50 cm) on all sites constituted only a few per cent. The Rubus hirtus populations on the "Szczoty" and "Dolina Łopusznej" sites established over 50 cm high shoots, potentially capable of producing roots with the probability of 0.14. Individuals producing a single the main primocane with the probability of over 0.7 were the most frequent. Less than 10% of the individuals which in the previous year produced at least one main shoot failed to establish new main shoots at all. The number of flowering/ fruiting individuals did not exceed 20% on none of the study sites. The studied populations produced a few new ramets. The results obtained from the research permit suggesting that the underlying bedrock is the primary, while light is the secondary, factor affecting the presence of Rubus hirtus plants. This species colonises areas where the stand canopy is broken even to a slight degree.

Opis:
The objective of the study was to analyse the site index (SI) of Douglas fir (Pseudotsuga menziesii) stands in relation to the forest habitat type, soil type and relief characteristics. We utilised infor− mation available in the Information System of the State Forests in Poland that included selected parameters describing habitat conditions and dendrometric characteristics of Douglas fir stands. In total, processed data referred to 863 stands with a total area of 1,644.45 ha. As the SI distribution was not consistent with the normal one (Shapiro−Wilk test, p <0.0001) we applied Kruskal−Wallis or Mann−Whitney tests to assess the significance of observed differences. Site index of surveyed stands ranged from 19.9 to 47.8 m, 32.6 m on average (standard deviation of 3.3 m). Douglas fir in northern and southern Poland characterized by higher SI than in western and south−western part of the country (HK−W=83.5; p<<0.001; fig. 2). Forest habitat type significantly distinguished analysed stands (HK−W=30.1; p<<0.001). The highest SI values were observed for mixed deciduous habitats (fig. 3). For more fertile fresh deciduous habitats Douglas fir achieved slightly lower site index, while the least fertile mixed coniferous habitats are characterized by significantly lower SI. Habitat moisture variant had no significant effect on the average SI values (HK−W=2.6; p=0.269). The highest values were found in strongly fresh habitats (32.8 ±4.1 m), while the lowest in the humid variant (31.7 ±3.4 m). We found significant influence of soil type (HK−W=23.2, p<0.001) even though the average SI values for each category were relatively similar (fig. 4). The highest values were observed for Cambisols (33.3 ±3.7 m), while the lowest for Arenosols (32.1 ±3.0 m). Particle size distribution is an important factor for Douglas fir site index (tab.). We found that the heavier material (the higher the content of silt and clay), the significantly higher SI values (HK−W=16.9; p=0.001). Mean SI for stands growing on former farmlands (32.0 ±3.3 m) and on forest areas (32.7 ±3.3 m) were not significantly different (ZM−W=1.73; p=0.084). There was no significant effect of the relief forms on site index surveyed Douglas fir stands apart from the fact that stands growing on slopes are characterized by significantly higher SI (ZM−W=1.99; p=0.047).

Opis:
The aim of the study was to verify the hypothesis that the quality of male roe deer hunted in the Kielce region depends on the selected characteristics of the place of their earlier habitat (forest cover, soil) and the age of the individuals. As a criteria to verify that hypothesis we chose carcass weight, weight and height of the antlers and skull dimensions. Material consisted of carcasses and antlers of 1349 bucks harvested in 169 hunting districts in the Kielce region (central Poland). We found that the individual quality of male roe deer was diverse. Significant impact was found for the forest cover, diversity of soil types and age of the individuals. Roe deer with the smallest carcass weight, having significantly lighter antlers occurred in areas with the forest cover of over 40% (tab. 1). In turn, in the filed−type circuits, where the forest cover does not exceed 20%, bucks were much heavier and imposed massive antlers (fig. 1). There was also evidence that in areas where the fertile soil dominated (rendzina and chernozems) individual quality of deer was significantly better than in districts where poor fawn and rust soils predominated (fig. 2). The examined environmental factors had the greatest impact on carcass or antlers weight, as well as the dimensions of deer skulls in case of the youngest bucks and their impact decreased with age. Optimum of the individual's development in terms of carcass weight and antler falls at the age of seven. Bucks harvested in the Kielce region, in comparison to the other populations in Poland, were characterized by good individual quality and slightly subsided only to individuals from the Lublin Upland (tab. 2).

Opis:
The objective of the paper was to estimate i) the carbon accumulation in soils of different forest site types as well as ii) its changes with regard to the depth of the soil profile. The investigation was carried out in the Przedbórz Forest District (central Poland) on 43 study plots, including different forest sites – fresh coniferous forest (Bśw), fresh mixed coniferous forest (BMśw), fresh mixed broadleaved forest (LMśw) and fresh broadleaved forest (Lśw). On each plot soil pits were dug and samples for laboratory analysis were collected. The following characteristics were determined in the soil samples: pH, the content of organic C and total N, particle−size distribution, the content of exchangeable Ca, Mg, Na and K, and hydrolityc acidity. The obtained results demonstrated that soils of Bśw, BMśw and LMśw sites characterized by higher carbon accumulation in surface horizon to 50 cm depth compared to the most eutrophic sites (Lśw). The rate of carbon accumu− lation in forest soils depend on the humus type which is connected with species composition of stands. Domination of Scots pine in stand affects the formation of ectohumus and leads to higher C accumulation in surface horizons on Bśw, BMśw and LMśw sites. In soils of Bśw, BMśw and LMśw sites carbon stored in the horizons to 50 cm constitutes 64−94% of the total carbon accu− mulated, while on the eutrophic sites (Lśw) this share amounts to 39−72%. The value of the total carbon stock in soils of fresh forest sites can be estimated on the basis of carbon stock in horizons to 50 cm depth.

Opis:
The morphology and properties of the post−arable soils that influence the trophic status of forest habitats on the Barycz river terraces (south−western Poland) were analyzed. The fieldwork included the characterization of the soil, tree layer, and the vegetation of the forest floor, as required for the forest habitat evaluation. In the collected soil samples, a set of physico−chemical analysis was carried out, that included: soil texture, bulk density, pH in KCl and water, total organic carbon, total nitrogen, hydrolytic acidity, base cations, and the content of plant−available phosphorus, potassium, and magnesium. Sandy post−arable soils in the Barycz valley have a thick, double− or triple−layered ploughed humus horizon, and the high stock of humified organic matter, nitrogen, and phosphorus, that emphasizes anthropogenic transformation of soils and differentiates them from the natural soils of river valleys. The diagnosis based on the soil trophic index (SIG) indicates generally lower trophic status (mesotrophic) as compared to the diagnoses based on forest floor vegetation and tree−stand (eutrophic status). The SIG model for the post−agrar moist valley habitats should be supplemented with the factors, which improve the apparent trophic status of sandy soils, including the thick humus horizon (post−ploughing) and shallow table of eutrophic ground water.

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 aim of the study was to determine the enzymatic activity and chemical properties of soil in selected stands of different age classes on two forest site types: fresh mixed coniferous forest (BMśw) and fresh mixed deciduous forest (LMśw). The investigations were carried out in Nowe Ramuki Forest District in 2013−2015 located in the central part of Warmińsko−Mazurskie administration district Poland. In organic and humus horizons following parameters were described: acidity in 1M KCL, content of nitrogen, carbon and exchangeable alkaline cations (Na+, K+, Ca2+ and Mg2+) as well as hydrolytic acidity. Enzymatic investigation included the measurements of urease, asparaginase, acid phosphatase and dehydrogenase activity. Content of C and N, sum of base cations (S), hydrolytic acidity (Hh), cation exchange capacity (PWK), base saturation percentage were significantly higher in organic than humus horizon. Enzymatic activity was connected with the content of organic matter, what resulted in higher activity in organic than humus horizon independently of site type and stand age. The concentration of organic carbon (C), nitrogen, C/N ratio, hydrolytic acidity and cation exchange capacity was higher on BMśw than LMśw site type. Activity of urease, acid phosphatase and dehydrogenase was lower in soils of LMśw than BMśw site type. Lower enzymatic activity may suggest lower intensity of decaying process of organic matter in these soils. Significant correlations between enzymes and chemical soil parameters were found. Significant correlation between enzymatic activity and soil chemical properties shows that biochemical parameters can be used as indexes of their productivity. Investigation of biochemical reaction intensity can be complement to soil chemical studies usually used in forestry.

Opis:
The study aimed to determine the influence of site moisture conditions on the health status of European ash. The research plots were located in the Babki, Konstantynowo and Łopuchówko forest districts, as well as in the Poznań Municipal Forests (western Poland). The research was carried out on 30 research plots established in the part of the stands with at least 80% share of ash in the stand species composition. Ash aged from 48 to 144 years. The scope of the research included: (1) selection of the research plots and determination of the forest site type, (2) assessment of site moisture conditions – the type and degree of moisture and the depth of the groundwater level, (3) selection of 15 trees belonging to the 1st and 2nd Kraft’s class and assessment of their health status using the synthetic damage indicator, which is based on the crown defoliation and vitality of upper part of the crown. Results revealed that the best health status of ash stands was noted in mesic broadleaved forest. In contrast, within the stands in moist broadleaved forest, alder−ash forest and riparian forest we observed the highest share of damaged and dying trees. The more detailed analysis of moisture conditions showed that the lowest damage of ash was noted within the stands with the groundwater level at depth below 1.8 m and up to 0.5 m. Moreover, a high share of healthy and weakened trees occurred also within the stands with water flowing down the slope and in the compact soils, where water does not undergo significant level fluctuations. The most damaged stands occurred mostly in dehydrated soils, as well as in the soils where the depth of the groundwater was between 0.5 and 1.8 m.

The main objective of this study was to demonstrate a relationship between the direction and effectiveness of impact of particular tree species on soil properties and the initial site fertility. The studies were conducted on two neighbouring experimental plots with different forest site types (fresh mixed coniferous forest – BMśw and fresh mixed deciduous forest – LMśw). The analysed species Norway spruce (Picea abies L. Karst.), European larch (Larix deciduas Mill.), Douglas fir (Pseudotsuga menziesii Franco) and penduculate oak (Quercus robur L.) were planted in three replications on 400 m2 plots. It was stated that: 1) the humification processes ongoing under the canopy of the analysed tree species are, to a large degree, determined by the type of forest site; 2) under the same tree species the content of calcium and nitrogen in the nitrate form was found to by markedly lower in the BMśw forest site; 3) in the BMśw forest site, the pH and electrolytic conductivity of the soil under the majority of the analysed tree species were lower; 4) the degrading impact of coniferous species on soil was noticeably stronger on the poorer BMśw forest site.
