Opis:
The contagion index [Gadow i in. 1998] is used to analyse a spatial pattern of trees in a natural forest stand occurring on a permanent study plot, located in a compartment 319 of the Białowieża National Park. By means of this index it is found that at a small spatial scale, the random occurrence of trees is a dominating mode of tree spatial pattern. At the same time, the share of trees forming biogroups is estimated to ca. 25% (at average). The results are compared with similar analysis performed by means of the Donnelly index and the Ripley's K function.

Opis:
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 phytosociological investigations, carried out almost 60 years later, revealed that in case of both communities, significant, directional changes of their floristic composition took place. Particularly high rate of change occurred in case of the phytocoenosis representing the Serratulo−Pinetum community. In 1959 it contained a full set of characteristic plant species. During the study period, this community type representing the Vaccinio−Piceetea class, was replaced by the initial form of lime−hornbeam forest belonging to the Querco−Fagetea class. Also, in case of the previous Tilio−Carpinetum association, the significant changes in the floristic composition occurred, although not as large as in case of Serratulo−Pinetum community. 60 years ago this community type contained several plant species typical for thermophilous oak forests. Nowadays, it represents a typical form of lime−hornbeam association. The changes in both community types were mainly related to the strong expansion of lime and hornbeam, which took place during the study period and involved the whole study plot. As a result, the vegetation occurring on the study plot is much more homogenous now than it was ca. 60 years ago. The maintenance of Serratulo−Pinetum phytocoenoses distinguished by a high floristic diversity calls for active protective measures in all cases where such measures are allowed and where this community type can potentially develop.

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.

Opis:
An assessment of the current dynamic status of tree species occurring in the Strict Reserve of the Białowieża National Park is presented. On the basis of long−term trends and analysis of large−scale inventory data, the three major groups of trees are distinguished: 1) ‘safe’ group, containing hornbeam and lime, 2) ‘presently safe, but declining in a long−term run’ group, involving spruce, birch and alder, and 3) ‘threatened and highly threatened’ group, consisting of oak, pine, ash, maple, elm and aspen.

Opis:
Major results of the 45−year−long study on the dynamics of strictly protected forest stands, using 3 permanent study plots, 25×100 m each, located on a former narrow strip clear cut established in the beginning of the 20th century on the northern slopes of the Mt. Łysica (the Świętokrzyskie Mountains, Central Poland) are presented. The general development of forest stands is analysed, including change of overall density, tree mortality rate (general and by species), dynamics of basal area and average tree diameter, competitive ability as well as changing role of particular species (mainly European beech, silver fir, sycamore and Norway spruce) in formation of the general stand structure. The results of the study are compared with other investigations of similar type.
