Opis:
The aim of the study was to determine the influence of organic fertilization and mulching on the seedling vigour of European larch (Larix decidua Mill.) and occurrence of soil mites (Acari) in forest- and post-arable soils. Two different nursery experiments were carried out in the vegetation period of the year 2005 on light soils at two sylvan-natural regions of Poland. The first trial was conducted at Białe Błota near Bydgoszcz – on a brown podzolic soil. The second experiment – at Lipnik near Stargard Szczeciński – on an acid brown soil. The higher was the rainfall amount during the vegetation period, the lower was the seasonal irrigation rate supplied to European larch seedlings. Because of this the seasonal irrigation water rate applied at Białe Błota was higher than that at Lipnik. European larch seedlings grown on the forest soil were characterized by the increased height and the fresh mass than those cultivated on the post-arable ground. Seedlings grown in the forest soil on treatments mulched with litter were characterized by the increased height and the fresh mass of above-ground parts as compared to those cultivated on control plots (without mulching). Mulching with litter increased the number of mites, especially oribatid mites, as well as their species diversity. It can be recognized as the result of the positive influence of the mulching on the biological properties of the studied soils.

Opis:
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 problem of determining the dependence of the chainsaw on the density of wood, substantiation of effective options for the number of chainsaws in the assortment and whiplash method of logging is quite relevant. In the Far East of Russia, in particular, in the Amur region, the forest growth conditions are different from the western ones, and therefore, the properties of the wood differ from the generally accepted ones. The article describes forest growth conditions that influence the properties of the wood in areas of the Amur region. Using the method of density determination, the density of larch, pine and birch were studied for first time in the areas of the region. The dependence of the density on humidity, age, species, season of the year and the area of growth was found out. The results of the research showed that under humidity of 70%, the density of larch was 1088.99 kg/m3, it was 919.8 kg/m3 for pine and it was for birch 915.9 kg/m3.

The aim of this paper is to present a characteristic of loess permanent gullies, which form the branched erosion system, with the total length of almost 7.8 km, dissecting an erosion-denudation dry valley. Only 20%of the gully system catchment is cultivated as the result of steep slopes and considerable height differences up to 100 m. 80%of the catchment is covered by fir coniferous forest and Carpathian beech forest, and gully development is the result of intensive forest exploitation. Five types of gullies have been selected on the basis of the runoff directions, which are determined by the following: original relief, runoff concentration from fields, runoff concentration from fallplaces, skidding and course of forest roads used to carry a timber.

Opis:
The forest is becoming an important factor in maintaining the climate balance. Forest has a great influence on the regulation of global warming. In addition, forest plantations became the basis for conservation and recreation of biological diversity of flora and fauna. In connection with the aggravation of the ecological situation and the deepening of economic contradictions, the forest as a complex of resources for national security takes on special significance. The article examines the factors of changing the quantitative and qualitative characteristics of forest resources. The institutional problems of forest use and protection are considered. The analysis of joint management of forest resources in transboundary regions of Ukraine and Poland is given. Great attention is paid to assessing the assimilation potential of forest resources. The possibility of rational use of transegrain forests with the participation of international organizations is substantiated. The necessity of improving the ecological and legal relations between the European Union and Ukraine is substantiated.

Na podstawie pomiarów uzyskanych ze stacji meteorologicznej LZD Siemianice średnia z wielolecia 1975÷2006 roczna suma opadów atmosferycznych na badanym obszarze jest równa 560 mm (tabela 2). W półroczu zimowym w badanym wieloleciu średnia suma opadów wynosi 210 mm. Wartość średniej sumy opadów w półroczu letnim w danym wieloleciu jest równa 350 mm. Maksymalna zmierzona roczna suma opadów wyniosła 958 mm, natomiast najniższa jest równa 434 mm. W omawianym wieloleciu średnia roczna temperatura na analizowanym obszarze wynosi 9,0°C. Średnia z wielolecia temperatura powietrza w półroczu zimowym jest równa 2,4°C, natomiast w letnim 15,5°C. Najniższa temperatura w wieloleciu w półroczu zimowym wyniosła -0,4°C, a najwyższa 4,6°C, natomiast najwyższa temperatura w wieloleciu w półroczu letnim wyniosła 17,1°C a najniższa 13,6°C.
The research of water resource evaluation were carried out at three small forest catchment located at Wielkopolska region. G and G-8 catchments are located at Siemianice Forest Experimental Farm in southern part of Wielkopolska region. Hutka catchment is located at Zielonka Primeval Forest in central part of the region. The maximum water flow in analyzed G, G-8 ditches and Hutka water-course always appeared in winter half-years. Meanwhile water flow in analyzed watercourses were always significantly lower in summer half-years and periodically they disappeared. It was also indicated that increase of groundwater levels is strongly connected with water retention in winter half-years. Meanwhile decrease of groundwater levels and water content in soil caused by higher evaporation were observed in summer half-years which had significant role in water balances of these catchments. The research carried out in a different habitat conditions indicated the smallest changes of groundwater and total retention in swamp habitats: mainly in ash-alder swamp forest and moist broadleaved forest. Higher differentiation of water retention changes and groundwater levels was observed in moist mixed broadleaved forest, moist mixed coniferous forest, as well as in fresh mixed broadleaved forest and fresh mixed coniferous forest. It suggests the possibility of better usage of their retention capability. Optimum water level sustaining in forest habitat soils allows better usage of retain water was also indicated in the research, which is in accordance with forest needs and environmental protection requirements.

Opis:
This study concerned 26 forest stands with Douglas fir situated in Lower Silesia, Great Poland, Pomerania, Warmia and Masuria. Each stand was represented by 24 trees. From each tree an increment core was taken by Pressler’s borer. The principal components analysis showed that the first three principal components accounted for 73% of the variation of chronologies in total. The first principal component was the most convergent with the mean air temperature curve for January–March, the second with the total precipitation for June–August, and the third with the mean temperature for June–August. The first principal component always integrated the chronologies and decided on a similar rhythm of changes in the tree-ring widths. The annual variation of tree-ring widths was also affected by precipitation in summer (June–August), but this differentiated the chronologies. This was reflected by the dispersion of chronologies in respect to the eigenvectors of the second principal component. The third principal component also differentiated the chronologies. Separate groups were formed by the most eastern and the most western localities of the territory under investigations. Thus the Douglas fir growth reactions were mainly affected by the thermal and pluvial conditions of summer and, to a lesser, degree by the thermal conditions of winter. On the basis of these results it was possible to distinguish the dendroclimatically homogeneous regions in western and northern Poland.

Opis:
The calamity windstorm in November 2004 caused dramatic changes of land cover in the Tatra Mountains. The bora have destroyed then more than 12,000 ha of forest and principally affected the habitat structure in the Tatra National Park. The aim of this contribution is to quantify changes in forest fragmentation in 2000 and 2006. We present forest fragmentation maps related to the years 2000 and 2006. The CORINE Land Cover data layers CLC 2000 and CLC 2006 converted to raster format were used as the input data in the process of forest fragmentation assessment. Forest pixels were classified according to fragmentation indices measured within the surrounding landscape as the forest core, forest patch, forest edge, and perforated forest. Decrease of the compact forest areas (forest core) by about 9% was recorded. On the other side, increased percentage of disrupted forest areas was observed. Decrease of the area of the CLC forest classes (classes 311, 312 and 313) on land cover maps from 2000 and 2006 was connected with an increased number of transitional woodland/shrubs polygons (CLC class 324). These results suggest a temporary fragmentation with possible forest regeneration. On the other hand, forest destruction in the National Park facilitated the development of travel and tourism (new hotels, ski parks, etc.). An increased number of construction sites (CLC class 133) indicate that an urban sprawl associated with a permanent forest fragmentation can be also expected in the future.

Opis:
The study investigates the intra-population variability of the growth and quality traits of Norway spruce populations from Bliżyn and Zwierzyniec Lubelski. The two populations are included in the IUFRO 1972 experiment and exhibit a high growth dynamics and a narrow crown form. The research was carried out on the experimental plot established in 1996 in Chrosno (Kutno Forest District) using 8228 two-year-old seedlings planted in a single-tree plot design at a spacing of 1.5 × 1.5 m. The seedlings represent 191 open-pollinated families, among them 93 families of Norway spruce from the Bliżyn region and 98 families from the Zwierzyniec Lubelski region. The height, height increment and DBH of trees were measured periodically, and some quality traits were assessed. The last results come from the measurements done on the trees aged 10 years. It was found that the differences between the two populations of Norway spruce are statistically nonsignificant but both of them show wide within-population variability. This suggests that they have the potential to flexibly respond to future changes in the growth conditions or to seed transfer to other seed zones. Survival in the environmental conditions of the experiment was independent of family.

This paper analyses wave attenuation in coastal mangrove forests in Vietnam. Data from 32 mangrove plots of six species located in 2 coastal regions are used for this study. In each plot, mangrove forest structures and wave height at different cross-shore distances are measured. Wave height closely relates to cross- shore distances. 92 exponential regression equations are highly significant with R2 >0.95 and P val. <0.001. Wave height reduction depends on initial wave height, cross-shore distances, and mangrove forest structures. This relationship is used to define minimum mangrove band width for coastal protection from waves in Vietnam.

Opis:
The following research on plant litterfall mass, dynamics, structure and chemistry was conducted from 2012 to 2014, on a 40- to 86-year-old stand of black alder (Alnus glutinosa) growing in a headwater area of the upper part of the valley of the Kamienna Creek (Middle Pomerania). Litterfall was collected every month with 20 circular traps, dried untill constant weight, divided into fractions, weighed and analyzed. The annual amount of litterfall deposited on soil during the study period ranged from 3482.5 to 4106.9 kg·ha-1, showing a dynamics pattern typical of temperate decidous forests. Leaves constituted the major fraction of litter with share of between 78.0 and 81.6% in its total mass. The contribution (in %) of twigs was 4.9-5.6, flowers 2.8-8.3, fruits 0.2-0.9 and other components 7.6-9.2. The relatively stable environmental conditions of headwater areas and the absence of disrupting factors during the study period were reflected in the low temporal variability of litterfall mass, dynamics and chemical composition of its individual fractions. The average annual pH of litterfall was 4.33-4.57. In general, litter was relatively rich in nitrogen and calcium but poor in phosphorus, potassium and magnesium. The content of Fe, Al and Mn was characteristic for these elements and low when compared to the other macroelements. The low contents of Cu and Zn confirm limited anthropogenic contamination of the investigated ecosystem with these metals. The annual return of the elements to the soil formed a series C>N>Ca>K>Mg>P>Mn>Fe>Al>Zn>Sr>Cu. A relatively large influx to the soil was noticed for nitrogen and calcium. Meanwhile, it was low for potassium, magnesium and phosphorus.
