    Opis:
    Artykuł prezentuje pojęcie i sposoby mierzenia różnorodności biologicznej oraz jej znaczenie, jako wskaźnika zrównoważonego rozwoju i ekorozwoju. Ocena bioróżnorodności może być przeprowadzana na różnych poziomach organizacji przyrody. Najwięcej używanych obecnie wskaźników jest związanych z różnorodnością gatunkową oraz ekosystemową (krajobrazową). Stwierdzono, że wskaźniki dotyczące stanu środowiska przyrodniczego mają zasadnicze znaczenie przy ocenie realizacji założeń zrównoważonego rozwoju, którego ważnym celem powinno być zahamowanie tempa wymierania gatunków na Ziemi.
    The article presents the concept and modes of measurement of biological diversity as well as its significance as an indicator of sustainable development and ecodevelopment. Estimation of biodiversity can be carried out on various levels of organisation of nature. The majority of currently used indicators are linked to species and ecosystem (landscape) diversity. It has been established that indicators concerning the state of the natural environment are of great importance for evaluation of fulfilment of the assumptions of sustainable development, for which the important goal should be the restriction of the rate of species extinction on Earth.

    Opis:
    Mycological data published in the years 2012−2017 in six papers on the exhibitions of fungi of the Białowieża Forest (NE Poland) was analysed to demonstrate that incidental, few days long field studies in that region may provide interesting and valuable data on fungal diversity and richness. The discussed papers, in addition to the lists of species presented, include information on some interesting taxa collected during the preparation of the exhibitions. This data complements the knowledge on the fungal biota of the Białowieża Forest and is documented by the herbarium specimens. There are 865 macrofungal taxa (72 of Ascomycota and 793 of Basidiomycota) mentioned in these papers. Almost half of them (421 taxa) were particularly valuable fungi, with 239 being new for the Białowieża Forest, i.e. they had not been reported from this area earlier. 75 taxa found during the field work preceding the exhibitions had not been found in Poland previously (e.g. Chromosera cyanophylla, Clitocybe collina, Cortinarius talimultiformis, Cystoderma subvinaceum). Moreover, 67 taxa have not been so far reported from other localities in Poland (e.g. Amylocystis lapponica, Pycnoporellus alboluteus and Steccherinum tenuispinum). 15 fungal species collected before the exhibitions are protected in Poland, 6 of them are strictly protected. 185 red−listed fungi were also found, among them 1 species with Ex (extinct) category (Scytinostroma galactinum) and 61 with E (endangered) category (e.g. Pholiota squarrosoides, Punctularia strigosozonata, Rigidoporus crocatus). An analysis of the published data indicates that even short−term, incidental studies may provide important and valuable data on the fungi of the Białowieża Forest and that the potential richness of its mycobiota is much higher than previously recognised and estimated. Presented results confirm the need for further basic research on the biodiversity of macrofungal biota of the Białowieża Forest. It should involve application of new research methods, participation of taxonomists specializing in specific fungal groups, identification of threats and establishing of a conservation program and population monitoring of the most valuable species in this area.

    Opis:
    Stand characteristics are important factors influencing the biodiversity of the herbaceous plants that play important roles in the functioning and shaping the structure of the forest. This study investigates the relationship between the characteristics of the tree layer and the diversity of the herbaceous layer in the semi−natural remnants of the former Sandomierz Forest (Kolbuszowa Plateau, SE Poland). The study was conducted in ‘Las Klasztorny' reserve on 40 circular plots (0.05 ha) centered on the nodes of a grid covering the area of the reserve. Each plot was analyzed in terms of the composition of the tree stand, and the height and diameter at the breast height (DBH) of live trees. In order to analyze species diversity in the herbaceous layer, the incidence of vascular plant species was recorded on 24 surfaces (1×1 m) along a transect passing through the center of each plots. For each plot the Shannon index of species diversity was calculated. Results were analyzed by multivariate PCA method. Average tree density in the reserve was 741 trees/ha and the average basal area was 33.4 m²/ha. Tree stands consisted mainly of Pinus sylvestris, Abies alba, Fagus sylvatica, Quercus robur and Carpinus betulus. Fir and pine were the most frequent. Pine had the largest share in the total basal area. The first and second PCA axis demonstrated high correlation of herbaceous plant diversity with tree characteristics (r=0.95 and r=0.71, respectively). The first axis showed the greatest negative relation with beech basal area proportion, and positive dependence on oak density and share of pine in basal area on the research plots. The second gradient showed a strong positive correlation with oak basal area proportion, and negative with trees density. Correlation analysis of tree stand characteristics and the herbaceous layer confirmed the negative impact of beech on herbaceous layer diversity. It also indicated a positive dependence of the herbaceous layer species diversity on species richness in the tree layer, oak density and average DBH. The results indicated a positive dependence of herbaceous plant diversity on the development of the tree stand. The observed greater diversity of herbaceous plants in the old growth forests with diverse spatial and species structures indicates the high importance of the old stands in maintaining forest biodiversity.

    Opis:
    The Wronie nature reserve was established in 1978 for conservation of Pomeranian fertile beech forest Galio odorati−Fagetum (=Melico−Fagetum) outside of the natural range of European beech Fagus sylvatica. Reserve is located in Golub−Dobrzyń Forest District (53°18'39.52"N; 18°54'3.89"E; N Poland). The aim of our study was to determine the influence of passive protection for beech forest herb layer biodiversity. For our research, we used four series of phytosociological relevés made in 1967, 1984, 1995 and 2005. To investigate changes in habitat conditions we used Ellenberg indicator values. Differences between years were analysed with ANOVA and Tukey test. In subsequent years, the frequency and cover of non−forest species, mainly from Epilobietea, Artemisietea, Trifolio−Geranietea and Molinio−Arrhenatheretea classes increased. This is caused by the increase in light availability, as result of disturbances in the tree stands (windthrow, oak decline, insect gradation). Light is the only Ellenberg coefficient that has significantly changed during 38 years (fig., tab. 2). Increase of light availability had no effect on biodiversity of forest herb species from Querco−Fagetea class. In comparison, with other studies in similar forest communities, our results suggests that passive protection might give different effects on biodiversity in similar forest communities, depending on tree stand dynamics.

    Opis:
    The paper presents the analysis of changes in two beech forest communities in the Kołowskie Parowy nature reserve (NW Poland). Within 21 years the frequency and cover of most species significantly decreased, including typical taxa for shady deciduous forests. Analysis of ecological indicator values showed that species richness is strongly correlated with light availability. The results suggest that passive protection promoted in Puszcza Bukowa forest brings negative effects for vascular plants biodiversity.

    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.
