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:
Changes in the herbaceous layer (vascular plants), taking place between 1959 and 2016 on the permanent study plot in the compartment 319 of the Strict Reserve in the Białowieża National Park are presented. Zaręba [1972] presented phytosociological research carried out in 1959 on the 1.2 ha plot. The author established 10 relevés (size between 100 and 400 m2), in which in total 91 different species of vascular plants were noted. In 2016, the similar study was conducted, using slightly modified methods (the inventory of plants involved the total area of the study plot). The comparison of data recorded during both investigations revealed that the total number of plant species declined from the initial 91 to current 83. During the ca. 60−year long period, 43 plant species disappeared completely and were replaced by 35 new species. In the declining group, almost the half (20) were species important from the point of view of nature conservation, including four Red List species (Arnica montana, Goodyera repens, Lathyrus laevigatus, Trolius europaeus), 10 plant species protected by law, and several other precious species related to rare and declining woodland community types. The obtained results confirm the findings of other authors describing unfavourable changes in the flora of the Białowieża Forest during the past several tens of years. The floristic richness is an important part of the overall biodiversity of Białowieża Forest. It appears that strict protection does not secure the maintenance of this key component. Thus, an attempt to preserve diverse values of Białowieża Forest on a sustainable basis should, first of all, look for a proper balance between strict and active protection. The later can (and should) be integrated within the multifunctional forest management, conducted on the prevailing area of the Białowieża Forest.
