    Opis:
    The paper discusses conditions and problems concerning natural regeneration of pine in the „Puszcza Białowieska” Promotional Forest Complex. The studies on pine regeneration established from self−seeding were carried out on permanent experimental plots occupied by fresh and fresh mixed coniferous forests site types. A space filling index used in the experiment was to define space occupied by pine regeneration the so−called „height sum”. A significance test of differences in mean values between the abundance and height sum (t−Student's test) was used for each experimental variant within the forests site types. Natural regeneration in the Białowieża Forest occurs infrequently. It can be found mainly in loose pine stands growing in fresh coniferous forest site types. Pine naturally regenerates most successfully in fresh and fresh mixed coniferous forest site types, on fenced clear−cuts with a few reserved trees, with soil prepared in furrows and well−performed tending treatments, as well as in pine stands with stocking 0.4 providing that the same conditions are maintained. The primary condition for successful natural regeneration of pine in the Białowieża Forest is its protection against animals in the form of fencing.

    Opis:
    The paper presents the state and conditions of oak natural regeneration in the „Białowieża Primeval Forest” Promotional Forest Complex. It has been stated that under natural conditions oak appears in all forest types but it infrequently grows into a stand. With the recent expansion of hornbeam, it is difficult for oak effectively to regenerate. It has been confirmed in this study that the shelterwood cutting system (leaving some trees to dye naturally) is the most efficient method of natural regeneration of oak in the Białowieża stands.

    Opis:
    Despite the fact that only parts of the Białowieża Forest are protected as a national park and nature reserves, the forest is nevertheless as a whole considered a U NESCO Natural Heritage Site, Biosphere Reserve and an integrated Natura 2000 site. In the presently ongoing debate on the conservation priorities regarding the natural value of this forest and the current bark beetle outbreak, two distinct approaches can be recognized: (1) management assumed to involve considerable interference with the forest ecosystems; (2) maintenance of ecological processes and spontaneous restoration of the forest communities. The Białowieża Forest – especially its strictly protected parts – is a “bastion” where species characteristic of ancient forests (including so-called primeval forest relicts) have survived until today. This has been achieved by maintaining the forest’s complexity in areas with considerably reduced human influence, but most of all by maintaining a full spectrum of forest communities, naturally developing forests diverse in age, species composition and spatial structure including stand dieback and breakdown. The following factors need to be taken into account in the protection of the Natural Heritage Site: (1) the internationally recognized value of the Białowieża Forest including its biodiversity, the level of preservation of forest communities and the ongoing natural processes; (2) existing documents and policies concerning nature conservation; (3) research findings from the Białowieża Forest and other natural forest complexes. The key priority is to limit any activities in this forest to an indispensable minimum, mostly concerning security close to roads and tourist tracks as well as collection of fire wood by locals. Without this strict protection, successive and slow anthropogenic transformation will result in the Białowieża Forest sharing the same fate as other forest complexes of the temperate climate zone in Europe or America and lose its globally appreciated value.

    Opis:
    Białowieża Forest (BF) is widely known for its outstanding natural values. The debate about the management/protection model, able to maintain all relevant values of BF on a sustainable basis, has a very long history. Currently, the main role in this debate is played by groups and organizations claiming that the major threat for the biological richness of BF is related to local forest management. In this paper, an attempt is made to verify this thesis. The extensive literature research reveals that vascular plants are one of the most threatened (and best documented) groups of organisms occurring in BF. It was found, for example, that in case of Serratulo−Pinetum (one of the most important woodland community type occurring in BF) the floristic diversity declines at the rate 0.6 species per year. However, similar situation concerns many other groups of species (e.g. lichens) as well. The recession of many species does not take place in the managed part of the BF only. This problem concerns also the areas which, since a long time already, have been subjected to the strict protection, like the ‘Strict Reserve' of the Białowieża National Park (comprising ca. 7% of the BF, under strict protection since ca. 100 years). Several factors and agents responsible for the general deterioration of natural values of BF were identified. Among other things, many authors underline the negative impacts of natural, successional processes taking part in areas which were ‘liberated' from the direct human impacts. Such processes are a direct cause of loss among many herbaceous species, particularly helio− and termophilous plants. Another important reasons for decreasing trends in many important elements of the local biodiversity are: strong reduction of open and semi−open areas (disappearance of the so called ‘cultural landscapes'), climate change, air pollution, deer overabundance, compositional impoverishment of many tree stands, invasive species of plants and animals. In conclusion, there are many factors responsible for decreasing diversity of BF and most of them have nothing to do with the local forest management. To preserve possibly high levels of the natural values of BF for future generations, a wise and complex conservation strategy is needed. As many other similar examples from different places over the world clearly show, the core element of such a strategy should be the principle of active management approach and not the out of action principle of ‘doing nothing'.

    Opis:
    The 19th century game management in Białowieża Primeval Forest (BPF), especially hunts for European bison, have been a subject of several works. The aspect of hunts motivated by research and museum needs have not been described in detail yet. The paper attempts at describing the administrative process behind such hunts and collecting all records of bison hunted or captured and carcasses acquired in BPF for museums, natural collections and universities in 1811−1914 (period covered by manuscript sources and published historical works with data on bison hunts available). Based on available sources, we calculated that in the period in question a total of 153 bison were hunted during ‘recreational' hunts (by tsars, their families and exalted guests with special tsars' permissions) and 56 were shot for purposes of study and research – therefore 27% out of 209 hunts had research motivations. Furthermore, 72 bison were captured alive (for zoos, cross−breeding and taming experiments) and carcasses of 89 bison (plus another 9 of unknown origin) were sent to museums and universities all around Europe. We believe that this little known aspect of the 19th century game management in BPF has had a significant impact on informing the scientific world and especially the general public about the European bison species, which in turn could have contributed to successful, international collaboration after the extinction of the species in the wild in 1919.

    Opis:
    The main aim of the study was to determine changes in the species composition and structure of natural tree stands in the Białowieża Forest (BF), which occurred in the years 1975-2012, as well as to evaluate their trends, directions and rate. The study was carried out on 121 permanent research plots (50×50m), which represented the most important forest phytocenoses in BF, i.e. fresh pine-whortleberry forest Vaccinio vitis-idaeae-Pinetum Sokoł. 1980, fresh mixed spruce-reed grass forest Calamagrostio-Piceetum Soko³. 1968, oligotrophic form of hornbeam - bastard balm forest Melitti-Carpinetum Soko³. 1976, different forms of linden- hornbeam forest: Tilio-Carpinetum Tracz. 1962, alder-ash forest Fraxino-Alnetum W. Mat. 1952 and sub-boreal spruce forest on bog moss Sphagno girgenshonii- Piceetum Polak. 1962. On the plots selected, there was measured the diameter at breast height (DBH) of all trees, as well as every tree and shrub up to 1.3 m high was counted and described with reference to species. The measurements and observations were regularly repeated every 10-15 years. The results showed that over the last period of nearly 40 years, there has increased a share of common hornbeam Carpinus betulus L. in the structure of forest stands in numerous BF associations. This tree species has expanded into different forest habitats including poor, medium fertile and wetland sites. The results obtained indicate a trend towards formation of linden-hornbeam forests in BF phytocenoses. The most evident changes were recorded in hornbeam - bastard balm forest. In natural conditions of the majority of forest associations analyzed, there prevailed hornbeam trees in forest regeneration, except for the stands in fresh mixed pine forest and spruce forest on bog moss. In the latter two cases, hornbeam showed signs of its presence in the last observation period. Norway spruce (Picea abies L.) retreated into oligotrophic forest associations. In the recent decades, spruce populations have been dramatically reduced in the stands in mixed coniferous and different kinds of broadleaved forests. There have also decreased a share of light-demanding tree species, such as Scots pine (Pinus silvestris L.), pedunculate oak (Quercus robur L.) and silver birch (Betula pendula L.) in BF tree stands, including their regeneration-layer. Especially, Scots pine regeneration has not been successful. In the short period of time (about 15 years) there has been observed rapid and outsized reduction of ash Fraxinus excelsior L. populations in natural conditions of alder-ash forests. All through the last 10-15 years, there has been also observed increased rate of change in stand species composition. The trend and rate of change in stand species composition point out to a possibility of human intervention towards stimulation of natural regeneration so as to preserve valuable populations of threatened tree species in the Białowieża Forest.

    Opis:
    Since several years already, a massive infestation of bark beetle has taken place in the Białowieża Forest, decimating a local Norway spruce population. In consequence, many open areas appeared, practically deprived of trees and other forest vegetation. The existence of such areas has a very negative impact on multiple values of the Białowieża Forest: natural, social, economical and landscape−aesthetic values. The local forest administration prepared a strategy aimed at active restoration of diverse woodland communities typical for the Białowieża Forest in all places, where bark beetle infestation wiped up the spruce stands. Those plans were criticized by representatives of the environmental organizations who blamed the foresters for transforming the Białowieża Forest into ‘plantation’ and claiming that such measures are inconsistent with the existing forest management and protection plan. The postulate of environmentalists is that the recovery of woodland communities should proceed completely naturally. Taking into account the above mentioned controversies, in this paper we examine the issue of natural regeneration in the Białowieża Forest in detail. In particular, we try to determine to which extent this method of forest reproduction enables re−establishment of compositionally diverse woodland communities, distinguished by a high level of biological diversity and able to provide a wide range of commodities and benefits important for today’s society. Based on an extensive literature review we show that a combination of different (abiotic and biotic) factors, influencing establishment and subsequent growth of seedlings and saplings in the Białowieża Forest has long been strongly unfavorable for many tree species. In this regard, one should particularly emphasize the negative role of large herbivores, especially red deer, which is present in the Białowieża Forest since the end of 19th century, when it became a private hunting ground for Russian tzars. The devastating effect of deer browsing on natural regeneration is a well−documented phenomenon and widely recognized problem in the forestry practice. The fencing of young forest generation against game pressure is an indispensable measure, needed to secure the continuous existence of several tree species (first of all those palatable and vulnerable to browsing). Very strong arguments for an active approach to the described problem delivers also a long−term study on natural forest dynamics conducted since 1936. It shows that under conditions of strict protection the regeneration capacity of the Białowieża tree species is very variable. These differences lead to the compositional simplification and impoverishment of many tree stands, with numerous negative consequences for local biodiversity. We underline that an active management strategy is a basic prerequisite for maintaining a diverse character of the Białowieża stands and their ability to provide all important ecosystem services on a sustainable basis. Such a strategy should include, beside of the phase of establishment, also the subsequent developmental stages of new forest generations. The general goal of such a strategy should be to secure a possibly high diversity of tree composition and to enable the development of tree species representing a full range of life−history strategies and playing different successional roles: from typical pioneer species, through intermediate, to climax species.
