    Opis:
    This paper presents an overview of bird research carried out in the Borki Primeval Forest during the last 30 years. The Borki Primeval Forest can be considered as one of the most important forest bird sites in Poland. Its avifauna comprises 139 breeding species, including 11 rare and endangered species listed in the Polish Red Data Book of Animals as well as 30 species listed in Annex I of the EU Birds Directive. Despite its relatively small area, the Borki Primeval Forest holds at least 1% of Polish breeding population of as many as 12 bird species . For seven out of these species it is one of the most important breeding sites in the country. The avifauna of the Borki Primeval Forest consists mostly of typical forest birds including 24 indicator species which are associated with natural forests. The richness of bird species in the Borki Primeval Forest and the abundance of several valuable groups of breeding species are the result of a high landscape and habitat diversity as well as a relatively small anthropopression combined with a high degree of naturalness of forest stands.

    Opis:
    The composition and structure of the breeding bird community in the Borki Forest in north-eastern Poland were investigated during two separate periods: 1994–1996 and 2012–2014. Bird censuses were carried out in three plots located in mature oak-hornbeam, ash-alder and mixed coniferous forest stands. A standard combined mapping technique for estimating the number of breeding birds was applied. A total of 74 bird species bred at least once within any plot during 1994–1996 or 2012–2014. The structure of the bird assemblages on particular plots displayed a high degree of similarity, exceeding 75%, which means that they represent essentially the same bird community. However, the investigated assemblages have changed substantially over the 20 years. Both, the number of breeding bird species and the population densities on all plots, were much higher in 2012–2014 than in 1994–1996. The mean number of breeding species on all plots was over 50% higher in 2012–2014 than in 1994–1996, whereas the mean total density of breeding pairs increased by more than 60%. Total population densities on the plots increased as a result of an increase in population densities of individual bird species combined with an increase in the number of breeding species. Due to different rates of population growth for certain species, also the composition of dominating species group have changed. The observed changes in the avifauna of the Borki Forest were most probably due to an enrichment of the forest habitats structure, which was caused by natural factors, such as ageing of forest stands, forest succession and a change in water regime by beaver dams, as well as by forest management, including group felling within or in the vicinity of plots and uncovering of the forest edge.

    Opis:
    The utility of phytocenotic indices in the diagnosis and classification of forest sites might be limited because of vegetation degeneration in managed forests. However, even in secondary communities it may be possible to determine indicator species, although these may differ from typical and well known plant indicators. The aim of this work was to assess the vegetation diversity of Scots pine stands in representative forest site types along a moisture and fertility gradient. In total 120 sample plots from Turawa forests were included in the study. These plots represented young (21–40 years) and old (> 80 years) Scots-pine-dominated stands. The forest sites were categorized according to Polish site classification. Four site categories were studied: Boew (very nutrient-poor and mesic sites), BMoew (nutrient-poor and mesic sites), BMw (nutrient-poor and moist sites), LMw (quite nutrient-rich and moist sites). The species composition of the forest patches studied hardly differed among forest site types. Almost all of the vegetation in site Boew was different from both moist site types (BMw and LMw). Sites Boew andLMwhad the exclusive species determined as site indicators. Moreover, young stands had their own site type indicator species which differed from old stands. Numerical classification showed that only two plant communities were widespread: Leucobryo-Pinetum in Boew and BMoew, and the community of Pinus sylvestris and Molinia caerulea in BMoew, BMw, LMw. In secondary communities typical indicator species may not be useful, but it is possible to determinate species that are locally unique to forest site type. Despite the convergence in the composition of the plant community resulting from tree stand unification, plant communities have the capacity for a more diverse composition. Tree stand conversion can increase phytocenotic diversity.

    Opis:
    Faunistic and ecological studies on saproxylic Collembola species were carried out in the Wigry National Park (NE Poland). Nine sites representing Tilio-Carpinetum, Serratulo-Pinetum and Peucedano-Pinetum habitats each including three different levels of disturbance were visited twice in 2015. Samples from fallen logs in different stages of decay, neighboring litter and soil as well as arboreal epiphytes were taken on each visit. The Collembola specimens were then extracted using Tullgren funnels resulting in a total of 73 838 specimens from 270 samples. Specimen identification revealed the occurrence of 63 species, including 5 saproxylobiontic, 7 saproxylophilous, 4 xerophilous species living in epiphytic mosses and lichens as well as 47 hemiedaphic or euedaphic species. This composition of saproxylic fauna seems to be typical for the region with the most diverse assemblages being found in Tilio-Carpinetum habitats, while Serratulo-Pinetum and Peucedano-Pinetum are clearly less diverse. Additionally, a slight decrease in the number of Collembola species with increasing forest disturbance was observed. Furthermore, an increase in the number of Collembola species with the degree of dead wood decomposition was also found. This indicates that saproxylic springtail assemblages are sensitive to anthropogenic changes.

    Opis:
    The paper presents the results of a lichenological study conducted in 2012 in the 'Lekowo' forest complex, situated in the north-western part of Mazovia (Forest Division of Ciechanów). It is the largest forest complex in the area, covering 1596 ha. The research area comprises two small nature reserves ('Lekowo' – 5.31 ha, and 'Modła' – 9.36 ha) with old-growth oak trees (160–200 years of age) and adjacent managed pine forests (76-107 years of age). The aim of this study was to investigate the species composition of the lichen biota in both reserves and to determine the role of nature reserves in preserving lichen diversity. Results of the study showed that old-growth stands, in particular those composed of oak trees above recommended felling age, provide habitats for a large group of stenotopic forest lichens which are absent in managed forests. The 'Lekowo' and 'Modła' nature reserves, despite their small areas, are valuable refuges that help to conserve remarkable lichen diversity at the local scale, and serve as potential diaspore sources for many rare and threatened lichen species.

    Opis:
    The aim of this work was to expand current knowledge on the species composition and distribution of the jewel beetles (Coleoptera: Buprestidae) in the Białowieża Primeval Forest (BPF) based on research conducted in the years 2000–2018 and a literature review. The BPF is considered the best-preserved forest of the European lowland and is a reference point for all forest research. Thus, knowledge of its fauna is vital. This research was conducted and incorporated the whole Polish part of the BPF, including Białowieża National Park (BNP), using standard methods for faunistic studies of terrestrial beetles. We also investigated potential microhabitats of saproxylic buprestid beetles and reared larvae from inhabited host material. Collected larvae and/or pupae were identified in the laboratory or grown to the adult stage. However, most specimens were collected using various traps (Lindgren, Moericke, barrier type Netocia and IBL-2), especially traps placed in the upper tree canopy. Two species previously unrecorded in the BPF (Agrilus graminis, A. mendax) and new information on several of the rarest Central European Buprestidae species (Buprestis splendens, Eurythyrea quercus, Anthaxia chevrieri, Chrysobothris chrysostigma, Agrilus antiquus croaticus, A. ater, A auricollis, A. convexicollis, A. pseudocyaneus) are presented here. Currently, 54 species of Buprestidae are known to occur the BPF area, of which 49 were collected from the Polish part and 26 were collected from the Belarusian part, whilst two species (Dicerca berolinensis and Eurythyrea austriaca ) have no specific location data. In the BNP, which covers about 17% of the Polish part of the BPF, up to 39 species of buprestid beetles have been found. We also provide an original key for differentiating Agrilus nicolanus – a species recently discovered in Poland (BPF and Biebrza Valley), that was previously known to occur only in Asia and the Lipetsk region in the European part of Russia – from Agrilus betuleti species group. In conclusion, the BPF is an important refugium of buprestid beetle richness including known forest relics.
