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...
The diversity and sustainability of species composition are important topic of forest research. The possibility to observe the coexistence of tree species in a given forest patch and their succession in the next generation is limited because there are few forests unaffected by management activities. For this reason, the study was conducted in the oldest part of the Białowieża National Park, called...
The long−term changes of vegetation cover at the level of woodland community taking place between 1959 and 2016 on the permanent study plot located in the compartment 319 of Białowieża National Park are discussed. In 1959 two distinctive woodland community types occurring on sample plot were distinguished: subboreal mixed pine−oak forest (Serratulo−Pinetum) and hornbeam−lime forest (Tilio−Carpinetum)...
The paper presents the main results of the comprehensive inventory of monumental trees in the Strict Reserve of the Białowieża National Park, which was conducted in years 2002−2017 on an area of ca. 4700 ha and included all live trees with diameter at breast height (dbh) exceeding a minimum threshold value ranging from 60 cm for hornbeam to 120 cm for oak. For every tree fulfilling this condition,...
In Poland, the stormy discussion on the future of the Białowieża Forest has been ongoing already for a long time. The disputes are mostly focused on seeking answers to two questions: how to protect these unique forest ecosystems and whether forest management threatens their naturalness. The discussion has grown stronger after the recent, enormous outbreak of Ips typographus in the Forest. The Białowieża...
Abundance of red fox (Vulpes vulpes) populations in Poland and Europe have increased in the past decades, especially in the areas of high anthropogenic transformation. The aim of this study was to assess the current density of red fox in natural forests and to analyse changes in its abundance since 1981. The fieldwork was carried out in Polish part of the Bialowieża Primeval Forest (BPF), including...
