    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.

    Opis:
    The research on ground beetle assemblages was carried out in the virgin forests of the Białowieża Primeval Forest and in managed forests. Ground beetle assemblages in restocked cutting areas were characterized by lower values of the indicators characterizing the state of their successional development: MIB and SCP, participation of relict and wingless species. No differences in the number of species harvested in virgin forests and regenerated stands were confirmed.

    Opis:
    A new stand of rare in the Polish flora subshrub of Fabaceae family − Genistella sagittalis was recorded in 1997 in the area of Kozienicki Landscape Park and subjected to monitoring. The analysis covers the observation period from 1997 to 2007. On the basis of phytosociological relevés a negative effect of such factors as undergrowth overshading and interspecies competition on condition of Genistella sagittalis population was stated. The species demonstrates expansive tendencies in insolated habitats of little undergrowth cover. The population seems to be stabile and is not endangered at present.

    Opis:
    Nearly 27 000 individuals of 10 species belonging to the Carabus genus were caught on over 160 research plots in 13 different habitats in the Białowieża Primeval Forest, Poland. The body length of eight species was analysed. The mean body length ratio of two adjacent species ranged between 1.00−1.10, irrespective of the number of the number of Carabus species in the assemblage. The mean ratio of the smallest to the largest species increased with the number of species in the assemblage. To study coexistence mechanisms further, automatic traps were used to catch carabid beetles in decaying stumps and tree holes. In tree holes, the species C. hortensis was caught in the greatest numbers. Morphological differences and ecological preferences suggest spatio−temporal niche partitioning as the main coexistence mechanism for Carabus species in this forest.

    In the paper attention is given to the occurrence of carabid beetles in the environment of fallen decaying trees and hollows of standing trees. The catches of carabids in these environments are on the level of 1/6 of the catching efficiency of Barber's traps, which emphasizes the importance of such environments for epigeic carabid beetles. The paper discuses the causes of carabids to visit trees, as well as differences in their activity when on trees resulting from differences in anatomy of legs of these insects.

    Opis:
    The paper presents the state and conditions of oak natural regeneration in the „Białowieża Primeval Forest” Promotional Forest Complex. It has been stated that under natural conditions oak appears in all forest types but it infrequently grows into a stand. With the recent expansion of hornbeam, it is difficult for oak effectively to regenerate. It has been confirmed in this study that the shelterwood cutting system (leaving some trees to dye naturally) is the most efficient method of natural regeneration of oak in the Białowieża stands.

    Opis:
    The ‘Tisovik’reserve, located in the Belarusian part of the Białowieża Forest, holds an isolated relic stand of silver fir, situated 120 km to the north-east of the main forest. In order to preserve this relic fir stand, a ancestral conservative tillage consisting of the Jd 92 trial (plot I) and the Jd 94 trial (plots II and III) was established between 1992 and 1994 in the Polish part of the Białowieża Forest on the territory of the Hajnówka Forest District. The growth and development of the progeny of 20 firs were characterized by means of long-term observations made in these trials. In 2000 (at the age of 18), the firs in the Jd 92 trial (plot I) reached an average height of 394.86 cm with a mean diameter at breast height of 42.42 mm and the average rate of survival amounted to 75%. In the Jd 94 trial, the rate of fir survival on plot II was 70% (at the age of 15) with an average height of 277.08 cm and a diameter at breast height of 36.62 mm, while on plot III only 50 trees with an average height of 198.6 cm and a diameter at breast height of 24.49 mm survived. The results of this study show that the fir progeny in the ‘Tisovik’ reserve is of high breeding value. Therefore, the silver fir seed stock of the ‘Tisovik’ reserve is suitable for the establishment of new plantations in the Polish part of the Białowieża Forest and the Mazury-Podlasie Region.

    The aim of this study was to: 1) describe the genetic structure of the population of old Picea abies trees in the Białowieża Primeval Forest and 2) design the genetic database for every examined tree in scope of 26 isoenzymatic loci containing: the genotype pattern, the number of stated alleles and the level of individual heterozygosity. We found that 101 out of 117 trees are characterized by a unique genotype pattern and 20 ones are completely homozygous individuals. The oldest Norway spruces in the Białowieża Primeval Forest are characterized by rather low level of genetic variation and their homozygous genotypes that are well adapted to their environment let them live to a ripe old age.

    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.

    Opis:
    The aim of this study was to characterize the texture of a primeval forest composed of Fagus sylvatica (L.), Abies alba (Mill.) and Picea abies ((L.) H. Karst). Empirical data were collected in the Babia Góra National Park (southern Poland) in the stand being under strict protection since 1934. 259 circular plots with a radius of 7.0 m and an area of 154 m² each were established in nodes of 20×20 m grid. For individual plots and blocks of the combined plots representing gradient of spatial scales between 0.015 and 0.640 ha, the number of trees, diameter at breast height (dbh) distributions, basal areas and the values of structural diversity indices of Gini (GI), Shannon (SH) and Staudhammer−LeMay (STVI) were determined. The indices were also calculated for several types of theoretical distributions. Based on the values obtained for the theoretical distributions, the individual plots and the blocks of the combined plots were classified as representing simple (GI≤0.30;STVI≤0.10), moderately diversified (0.300.45; STVI>0.30) dbh structure. For all the spatial scales analyzed the average values of GI and STVI indices reached the level typical for populations of a high structural diversity (i.e. exceeded the values of 0.45 and 0.30 respectively). According to the GI and STVI values, the portion of stand patches with complex dbh structure ranged from 70.9% and 68.2% at the individual plots scale, respectively, up to 100% in the blocks of 16 plots (4×4). In general, in all the spatial scales analyzed the spatial diversification of the dbh distributions and basal area levels was higher than in managed selection forests and much higher than in managed single−storied stands. The dominant frequency of highly diversified dbh distributions found in the analysed stand was not concordant with the predictions of the forest dynamics theory based on developmental stages, according to which in primeval forests with a significant partition of Abies alba and Picea abies should prevail stand patches of rather simple dbh structure, characteristic for the long−lasting optimum stage.

    Opis:
    The article presents a hypothetical history of a stand and the occurring changes resulting from the on−going regeneration processes in the Tilio−Carpinetum hornbeam community following the past forms of forest utilisation. The anthropogenic destruction of stands took place most probably at the end of the 18th century. The regeneration process started at the beginning of the 19th century had led to the appearance of a spruce stand which disappeared in the middle of the 20th century. A lime−spruce−hornbeam stand was formed in its place. Since over 70 years, the regeneration process has been continuing under strict protection regime.

    Opis:
    The research was conducted in three old−growth forests consisted of silver fir Abies alba Mill., European beech Fagus sylvatica L., and Norway spruce Picea abies Karst. located in the southern part of Poland (Żarnówka and Oszast) and the south−eastern Bosnia and Hercegovina (Perućica). The aim of the study was to compare basic stand characteristics and spatial heterogeneity in terms of variation in stand basal area and vertical structure. In each research area, small sample plots (0.015 ha) were localised in a regular 20×20 m grid covering approximately 10 ha. In each sample plot the diameter at breast height (d1.37 cm) and species of all live trees were recorded. For each plot the basal area of live trees and an index of structural diversification were determined. As a measure of structural diversification, the simple variance in tree height was computed and scaled through comparison with a hypothetical variance of the uniform distribution. The spatial patterns of basal area and structural diversification were tested with paired−plot approach. In addition, simulation techniques were used to model variation in the basal area of live trees dependent on spatial scale. The Carpathian and Dinaric stands considerably differed in basal area (ranging from 36.1 to 65.2 m2/ha) and volume (varying from 522 to 1176 m3/ha), but all of them had diameter distributions proximate to a negative exponential model. The basal area recorded on the 0.015 ha plots had a very similar pattern of variation, which could be generalised as a truncated normal distribution. The distribution of the structural diversification index was different and resembled an uniform (Perućica) or a bimodal distribution with modal values at its extremes (Oszast and Żarnówka). However, in the spatial scales above 1,000 m2 the index distri− bution become similar to a normal (Oszast) or a truncated normal (Perućica and Żarnówka) ones with high mean values, indicating the predominance of complex vertical structures. In general, the spatial variability in basal area and structural diversification of live trees tended to be random. These results suggest that the patch−mosaic assumption being fundamental for the developmental cycle hypothesis is inapplicable to the studied primeval forests. Regardless of differences in geographic location and site conditions, the studied stands show a similar spatial pattern of structural heterogeneity, suggesting a close resemblance of disturbance regimes driving its dynamics.
