Studies were carried out during 1987–1997 in four stands situated in the lower mountain zone, and representing the association <i>Carici-Fagetum abietetosum</i> (sample plots Facimiech and Walusi&oacute;wka) and the community of a transitory character between <i>Dentario glandulosae-Fagetum</i> and <i>Carici-Fagetum</i> (sample plots Gr&oacute;dek and Przelecz Sosn&oacute;w). The greatest volume increment was found in a pure fir (<i>Abies alba</i>) stand of Facimiech (9.4 m<sup>3</sup>/ha/year, i.e. 1.4% of actual stand volume determined in 1997) being in the optimum stage, phase of aging and regeneration, and the smallest one stand of Gr&oacute;dek (5.3 m<sup>3</sup>/ha/year, i.e. 0.9% of actual stand volume) being in the growing up stage, phase of selection forest. The stand of Przelcz Sosn&oacute;w was characterized by the greatest mortality of trees (volume of loss, i.e. 13.5 m<sup>3</sup>/ha/year). In this stand of a transitory character between the growing up and optimum stages, due to rapid mortality of fir the break up of the stand took place, and in consequence the growing up stage, phase of a little diversified stratified structure was developed. Volume of recruitment was the greatest in the stand of Facimiech, i.e. 0.05 m<sup>3</sup>/ha/year. In three fir (<i>Abies alba</i>)-beech (<i>Fagus sylvatica<i>) stands the proportions of fir and beech in stand increment differed from their proportions in stand volume. The percentage of fir in volume increment was smaller, and that of beech greater, than their percentages in stand volume. Processes of increment and mortality of fir and beech pointed to a progressive process of changes taking place in stand species composition, expressed by the increase of beech and the decrease of fir. The knowledge about values of loss, recruitment, and increment, expressed by the number of trees and volume units, may be of help in determination of the amount of cut in productive and protective forests managed according to a close-to-nature silviculture.

The Relationship

Abstract Effects of ungulate pressure on the development of young generation of trees is one of the most important issues in ecology and forestry. Ungulate pressure influence on the development of natural regeneration has been also reported from several national parks. Our study on the effects of ungulate browsing on the young generation of trees was conducted on more than 500 sample plots controlled during one growing season. The overall browsing pressure ranged from 7.6% in seedlings to 20.3% in low saplings. The pressure of ungulates on the regeneration of Picea abies, the dominant species in the Tatra National Park, was by and large below 1%. Broadleaved species were browsed more frequently. The relationship between the plot altitudes and browsing intensity was statistically significant for seedlings and low saplings; at the higher altitudes, the browsing pressure was greater. There was also observed a statistically significant relationship between the type of former management and the browsing degree in seedlings; in the areas subjected to “landscape protection”, the intensity of browsing was higher when compared to strictly protected areas. Pressure exerted by ungulates on tree regeneration was very unevenly distributed, i.e. some plots were heavily browsed and many others - not browsed at all. The most affected tree species were Salix caprea and Sorbus aucuparia, although the percentage of browsed individuals rarely exceeded 50%. Other species favored by ungulates was Acer pseudoplatanus; despite the high browsing pressure, this species was present among seedlings and tall saplings, suggesting that it would be able to recruit to the tree layer. Abies alba was browsed less frequently than the deciduous trees; however, among the tall saplings it was the third most browsed species.

Biogradska Gora National Park in Montenegro is part of the Bjelasica Mountain which belongs to the montane region of the Dinaric Alps. Biogradska Gora is one of the largest long-term preserved forests in the Southeast Europe. In this paper there were compared the main structural characteristics of the old-growth mixed forest of spruce (Picea abies L.), fir (Abies alba L.) and beech (Fagus moesiaca (Domin, Maly) Czecz.), from the preserved area of the Biogradska Gora, with similar managed forests from the same mountain. Basic insight into the structural characteristics of forests of spruce, fir and beech was obtained by analyzing tree species composition and two basic structural elements - number of trees and wood volume per unit area. The obtained data provides overview of the structural characteristics of these forests. The results revealed the production potential of the studied mixed forests. The average quantity of standing volume in old-growth forests of Biogradska Gora indicates very valuable and productive forest ecosystems. Presented data shows that forest ecosystems of spruce, fir and beech in the protected area of the National Park Biogradska Gora are characterized by structurally irregular forests with presence of old trees with relevant growing stock and optimal balance of beech and conifer species, while in managed forests on the same mountain, growing stock is very low and with structure which is far from optimal.

Comprehensive Study

Abstract The paper presents composition of vascular plant species in spring niches in the Ojców National Park (Southern Poland). 111 species of vascular plants, fourteen mosses, two liverworts and one species of ferns were recorded during the first comprehensive study carried out in 2009 and 2010. Plants occurring in these places showed different degrees of association with spring niches. The largest group was represented by accidental krenophytes (74 species), while spring plants - obligatory krenophytes, constituted only a small part of the local flora (5 species). Meadow species of the Molinio-Arrhenatheretea class and forest species of the Querco-Fagetea class, penetrating niche areas from the adjacent areas, were the dominating ones. Plants of aquatic and spring communities were scarce, due to the predominance of small type karst springs. The diversity of vegetation was significantly influenced by habitat factors such as availability of light, humidity or the amount of organic matter in the soil.

Abstract Silver firs (Abies alba Mill.) of natural origin occurring in the Belorussian part of the Białowieża Primeval Forest constitute an enclave situated 120 km to the north-east of a dense fir stand in the Polish part of the forest. In order to protect this population a reserve called ‘Tisovik’ was established. In this study, plant communities occurring in the ‘Tisovik’ reserve were described and its fir population (20 trees) was characterised in terms of its genetic structure.

The paper lists psyllids (Hemiptera: Psylloidea) found in and around the Ojców National Park and discusses some selected species. Of the 46 confirmed species, representing the families Aphalaridae, Liviidae, Psyllidae and Triozidae, 44 are reported for the first time from the Ojców National Park. The largest group of psyllids is constituted by taxons related to forests and meadow and herbaceous communities. The following species are of particular interest. Craspedoplepta flavipennis (Foerster, 1848), a species characteristic of montane and subalpine altitudes, has its northern limit in Poland. The boreal-upland Cacopsylla nigrita (Zetterstedt, 1828) and Craspedoplepta malachitica (Dahlbom, 1851) are considered to be typical steppe species in Poland.
