The paper describes current (in years 2007−2017) changes of basic parameters of forest stands that constitute the managed part of Białowieża Forest (ca. 53,000 ha), divided into three forest districts: Białowieża (12,600 ha), Hajnówka (19,700 ha) and Browsk (20,400 ha). The investigated tree stands represent different phases of ecological succession, modified by silvicultural treatments and other...
The paper presents the issue of conservation of species diversity of the Białowieża Forest in the context of both natural and human−related disturbances. These disturbances, in the authors’ opinion, were the main factor that shaped the unique species diversity of this area. Examples of natural disturbances occurring in the Białowieża Forest include the impact of wind, insect outbreaks and, to a lesser...
Data on sex structure and growth of the population is crucial for proper game management. Camera traps, which are of reasonably low cost, but very efficient, can potentially measure the aforementioned parameters. The paper objectives was to assess the share of bucks, does and calves in red deer Cervus elaphus population in the area of the Białowieża Forest. Two methods were used: camera traps and...
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...
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...
The paper presents a multifaceted structure of timber harvest in 2008−2015 in the Białowieża, Browsk and Hajnówka forest districts located in the Białowieża Forest. The object of the research, including the Białowieża National Park being a remnant of the primeval forests, is considered one of the most valuable forest areas of natural origin in Europe. The studies were made on the basis of the data...
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 Białowieża Forest, considered as the last primeval forest on the European Plain and in Poland mostly known as the oldest national park, in recent years has faced the bark beetle (Ips typographus) infestation located mostly in its managed part of three forest districts: Białowieża, Browsk and Hajnówka. Undertaken protection measures, mostly consisted of dead and infested trees removal, has induced...
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,...
The structure of timber sales in forest districts of the Białowieża Forest in the years 2008−2015 is presented. The Białowieża Forest is one of the most valuable natural areas in Europe. The data from the reports generated by the State Forests Information System of the Hajnówka, Browsk and Białowieża forest districts were used for the research. The information contained in the forest management plans...
