Opis:
The objective of the presented studies carried out in the Wkrzańska Primeval Forest (north−western Poland) was to determine the influence of ecotone structure on phytodiversity. Basing on data from three transects, it was shown that the inappropriate structure causes reduction in the number of plant species and communities as compared to typical forest phytocoenoses. It also results in the increase of non−forest flora from nitrophilous and meadow habitats.

Białowieża Primeval Forest
Opis:
The occurrence of the Common pipistrelle in the bat fauna of the Białowieża Primeval Forest was expected, because the taxon P. pipistrellus was previously comprised of two separate species. Earlier observations of P. pipistrellus in the Białowieża area can mostly be counted for by the new species Soprano pipistrelle, which is considered equally widely distributed in the area. In this study, we were able to record and distinguish several passes of the Common pipistrelle by means of bat detecting techniques. Bats were found in two locations, the first one being the Białowieża village, whereas the second one is the woodland in close proximity of the Czerlonka village. It is very likely, that this species is more widely distributed in the Białowieża area, especially in the vicinity of human settlements.

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.

białowieża primeval forest
Opis:
Stand damage risk model was applied to three forest districts located in the Białowieża Primeval Forest: Browsk, Hajnówka and Białowieża. For this purpose, information contained in the database of the State Forests Information System was used. The obtained values of the stand damage risk factor allowed assigning each stand to one of the six risk classes. Higher class indicates higher damage risk to stands. The share of the stand area was calculated for each class. The weighted average of the areal shares of stands in the two highest damage risk factor classes was used as a measure of wind damage risk to forests. The values of this measure for individual forest districts were as follows: Browsk – 27.3%, Hajnówka – 33.0%, Białowieża – 38.3%. The degree of risk to these forests ranges from average to high, which is mainly because of large proportion of the high, old−growth spruce stands. Forest stands of the Białowieża Primeval Forest with a high risk factor are threatened by damage in the event of strong winds in this area.
