The aim of this work was to determine the content of Mn, Zn, Cu, Pb, Cr, Ni and Cd in auto- and semihydrogenic soils of Bialowieza National Park and to find relationships between their occurrence and litho- and pedogenic features of these soils. Basing on geometric mean contents of the elements studied a quantitative series of their occurrence was established as follows: Mn (297) >Zn (29) >Cr (16) >Pb (12) >Ni (10) >Cu (8.0) >Cd (0.29) mg kg-1 d.w The distribution of the above trace elements in soil profiles is linked to the direction of progress of the soil forming processes and, to some extent, to the variability of soil texture (especially in not completely developed soils). In general, the mineral-organic (A) horizons were least abundant in Cr, Ni, Cu, Zn and Cd, followed by the illuvial (Eet) and bedrock (C) horizons of the soils studied. Statistical analysis shown a significant correlation between contents of Cr, Ni and Zn and clay and colloidal particle amounts as well as between the content of Pb and the amount of organic carbon

Long-lived clonal plants provide an optimal place for the natural storage of seeds as a ‘non-soil seed bank’. We tested the hypothesis that the size and species diversity of a non-soil seed bank deposited within the clonal plant Carex cespitosa depends mainly on the plant's size. To verify this hypothesis, an experiment was conducted on an unmown meadow in the Białowieża National Park. The emerging seedlings of different species originating from C. cespitosa tussocks of different size (large and small) were observed under greenhouse conditions for four years. The size of a non-soil seed bank was evaluated based on the number of seedlings. Significant differences in the seedling number were found between large and small sedge tussocks (Mann-Whitney test Z = 3.96, P < 0.001). However, the number of recorded species was independent of tussock size. Both types of tussocks were dominated by meadow, forest and swamp species (in decreasing order). Some of these species are no longer present in the studied area, or their occurrence is limited to small groups at the meadow's edges. A non-soil seed bank within the tussock cores of C. cespitosamay be, similar to a soil seed bank, a tool for studying the changes occurring in plant communities.

The wild boar is an omnivorous animal, and by foraging (rooting) disturbs the top soil layer. In some regions of Poland and Europe seasonal fluctuations in rooting have been observed. Wild boars not only eat plants, but also strongly modify their habitat. In Białowieża National Park wild boar most frequently visit oak-hornbeam forests on fertile soil. On sites where the forest floor is covered with dense vegetation the germination of seeds is difficult, and wild boar rooting can promote the removal of diaspores from deeper layers of the soil seed bank. Within a 3-year observation on 30 subplots about 10,000 seedlings emerged representing 38 species. Our study revealed that rooted patches are characterised by a very rich and diverse flora of seedlings representing mostly forest species, but their density is low. The dominant species germinating in the disturbed ground vegetation is Urtica dioica, a species forming the persistent soil seed bank. There is a possibility that seedlings of herbaceous plants emerging on permanently rooted patches are of exogenous origin, since the seeds germinating there were in many cases damaged by repeatedly rooting animals and had no chance for further growth and reaching the generative phase. However, the soil seed bank in the rooted area has to be analysed to confirm this theory, that they have exogenous or endogenous origin. Seedling density in a repeatedly rooted oak-hornbeam forest is determined by factors other than those related to rooting. In this context the present study did not demonstrate a negative impact of rooting intensity on seedling emergence.

Parki narodowe pełnią ważną funkcję w edukacji przyrodniczej, która to ma na celu popularyzowanie idei ochrony przyrody, jak również podnoszenie poziomu świadomości ekologicznej. Tworzone w parkach narodowych muzea przyrodnicze, ośrodki dydaktyczne, wyznaczane ścieżki dydaktyczne i szlaki turystyczne umożliwiają poznawanie najważniejszych walorów przyrodniczych danego obszaru, a jednocześnie są główną formą zagospodarowania turystycznego wykorzystywaną w działalności edukacyjnej. Ponadto organizowane imprezy edukacyjne w postaci warsztatów, konkursów czy rozmaitych wydarzeń cyklicznych stanowią jedne z podstawowych produktów turystycznych oferowanych przez parki narodowe. Celem przeprowadzonych badań było poznanie opinii turystów odwiedzających Białowieski Park Narodowy na temat prowadzonej przez niego działalności edukacyjnej oraz oceny tej działalności przez osoby z niej korzystające. Badania przeprowadzono metodą sondażu diagnostycznego z wykorzystaniem ankiety jako narzędzia.

National parks play an important role in environmental education, which aims to popularize the idea of nature conservation, as well as raising environmental awareness. Created in national parks natural history museums, educational centers, educational paths and trails provide to explore the most important natural values of the area, and at the same time are the main form of tourist infrastructure used in educational activities. In addition, educational events organized in the form of workshops, competitions and various periodic events are one of the main tourist products offered by national parks. The aim of this study was to investigate the opinion of tourists visiting Bialowieza National Park on the educational activities conducted by Park and evaluation of the activities which they benefit. The study was performed by diagnostic survey using a questionnaire as a tool.

The relationship between the straight line distances (SLD), obtained from telemetry locations, and actual distances travelled by wolves Canis lupus (ADT), measured by snowtracking, was investigated in Białowieża Primeval Forest, E Poland, in winter 1995/96. Radiolocations determined at 15-min time intervals approximated the ADT by wolves reasonably well. If wolves were relocated at 0.5- to 2-h intervals, SLD can be multiplied by a correction factor of 1.3 to obtain ADT. Within the range of SLD from 1 to 10 km, they could also be converted into ADT using a regression equation: ADT = 0.34 + 1.19(SLD), with standard errors of prediction ± 0.13 to ± 0.3 km. The average travelling speed of wolves was 3.78 km/h (SD 1.23, range 1.6-6.1 km). Wolves walking the forest trails, roads and frozen rivers moved significantly faster than in the forest. Also, individuals travelling with other pack members moved faster than those walking singly.

Foraging habits of two hand-reared moose Alces alces (Linnaeus, 1758) calves were observed from 22 June to 20 July, 1990. The animals foraged freely while wandering in the Białowieża National Park, Poland. The intensity of foraging was measured by counting the contacts (i.e. bites followed by swallowing of a plant part). Altogether, 4,408 contacts with plants of 42 species were recorded. During the month of observations the number of contacts and the number of species of plants eaten by moose did not increase significantly. There was a positive correlation between the number of contacts and the number of species of plants eaten by moose during a day. Some random choice of forage by the calves, statistically significant (but decreasing with time) quantitative differences in the food preferences between the two moose, behavioural data about strong bonds between moose calves and their mother, and comparison with the development of foraging habits in roe deer fawns formed a basis for the hypothesis that the mimicring of the mother's behaviour is an important mechanism in the development of foraging habits in moose calves.

Skulls of 145 adult wolves Canis lupus Linnaeus, 1758 from two areas of the highest wolf density in Poland (78 from the Carpathian Mountains and 71 from the Białowieża Primeval Forest) were measured using 17 selected characters. Values of cranial characters measured were similar to those of previous studies from mid- dleastern Eurasia. Generally, wolf skulls were larger in the mountain than in the lowland population; males from the Carpathian Mountains were larger than that from the Białowieża Forest, however females were slightly smaller than that in the Białowieża Forest. On both areas males were larger than females, but a difference between sexes was much highly pronounced in wolves from the mountain population.

Detailed knowledge of the foraging behaviour of endangered species, especially in relation to available resources, may be useful in conservation management. I studied the year-round foraging behaviour of the White- backed Woodpecker in broadleaved, primeval Białowieża Forest (NE Poland), and investigated how foraging time was divided among various substrates and foraging techniques. Of the 13 tree species used for foraging, woodpeckers were most frequently recorded utilising the three most common tree species: hornbeam Carpinus betulus, lime Tilia cordata and spruce Picea abies (totalling 61-68% of observed time), and the proportional use of tree species did not change seasonally. Observations of birds foraging on snags increased and foraging on fallen trees decreased from spring to winter. Foraging was most frequently recorded on dead substrates (72-85%), usually those covered with bark. Mean time of foraging on an individual tree increased significantly from spring to winter. The foraging techniques most often used by woodpeckers were bark-pecking (29-11%) and superficial wood-pecking (12-27%). During winter, foraging techniques did not change significantly in relation to weather. These results suggest that forest stand composition is less important to this species than tree condition. Most broadleaved tree species and, under some conditions, spruce can be utilised for foraging by this woodpecker if they provide dead or dying substrates.

W latach 1999-2007 analizowano miejsca i techniki żerowania dzięcioła białogrzbietego w aspekcie sezonowym w pierwotnych drzewostanach Białowieskiego Parku Narodowego. Dzięcioły żerowały na 13 gatunkach drzew, najczęściej na grabie, lipie i świerku (Tab. 1). Preferowane do żerowania były grube drzewa o średnicy pnia > 40 cm (Fig. 1). Od wiosny do zimy rósł udział żerowania na stojących martwych, a malał na leżących drzewach (Fig. 2). Dzięcioły najczęściej żerowały na martwych częściach drzew (72-85%). Wiosną dzięcioły żerowały średnio najwyżej, zaś zimą najniżej (Tab. 2). Średni czas trwania żerowania wydłużał się od wiosny do zimy (Fig. 3). Zimą ptaki spędzały na żerowaniu w jednym miejscu tym więcej czasu im było zimniej (Fig. 4). Najczęściej stosowanymi technikami żerowania było kucie kory (29-41%) oraz płytkie kucie drewna (12-27%). Otrzymane wyniki i porównanie z podobnymi badaniami z innych terenów wskazują, że skład gatunkowy drzewostanu jest mniej istotny dla dzięcioła białogrzbietego w porównaniu do kondycji drzew. Większość gatunków liściastych a także świerk może być wykorzystywana do żerowania przez tego dzięcioła pod warunkiem, że dostarczają one martwego drewna. Z powyższych badań wynika, że dzięcioł białogrzbiety jest gatunkiem w pewnym stopniu plastycznym, dla którego nie jest ważny skład gatunkowy drzewostanu, a występowanie odpowiedniej ilości martwego drewna.
