Opis:
During the period from 2003 to 2011 observations of carabid community regression and selected habitat indicators were conducted on 15 plots in stands that had been disturbed by a hurricane and on 15 plots in control stands. Regression of carabid communities delayed 3−4 years was observed, consisting in increases in the number of species and the proportion of xerophilous species and reductions in the percentage of forest fauna and in mean individual biomass. Only after 7 years did these indicators begin to show a tendency in the reverse direction, albeit not very strong, indicating that carabid communities had begun to regenerate.

Opis:
The aim of the study is to analyze changes in the species composition and in the diameter structure of the main forest−building species in the Roztocze National Park (central−eastern Poland). The research was carried out on 315 permanent monitoring plots. The range of collected data included: type of protection (strict and active protection), forest site type, tree species and their dbh (>7 cm over bark). Measurements and observations were made in 2007 and repeated in 2017. There was a significant reduction in the number of all tree species, except of beech Fagus sylvatica, regardless the protection status. Despite this, the basal area for the strict and active protection zone was similar both in 2007 (37.77 and 36.39 m2/ha, respectively) and 2017 (37.17 and 37.85 m2/ha, respectively). In the whole park, the number of large trees (mainly beeches) with high individual basal area increased, while the number of young generations of all species decreased. In the strict protection zone, the admixture species (decrease by 27.3%), as well as hornbeam Carpinus betulus (decrease by 22.8%), are not particularly competitive with beech. A similar tendency, although mitigated by active silvicultural treatments, was also observed in the active protection zone, in which admixture species have lost 24.8% while hornbeam 16.2%. In the strict protection area, there was a significant reduction in the number of fir Abies alba (by 14%). In the active protection zone fir increased its range and basal area, and maintains its population practically unchanged. There was also a decrease in the number of young generations, as evidenced by changes in the frequency in the 7−16 cm dbh class. The highest level of reduction in this class was found for pine Pinus sylvestris (by 64.8%), rare species (40.4%), hornbeam (31.2%), oak Quercus robur (26.6%), and spruce Picea abies (20.5%). Only beech increased the abundance in this class (by 1.4%) as well as in the next 17−26 cm class (even by 14.2%). The presented significant changes in the species composition and structure of basal area of the stands in the Roztocze National Park that occurred in the 10−year period, indicate a significant role of tending cuts in maintaining proper species composition, appropriate diameter structure of stands, their stability of natural richness and high level of diversity of forest ecosystems.

Opis:
Modern multifunctional forest management needs indicators showing the state of forest environment. Commonly used solution is monitoring of the abundance of species with specific environmental requirements. This paper analyses the possibility of use of the biggest European woodpecker (Dryocopus martius) as forest management quality indicator. The black woodpecker resides in all types of forest sites. The species prefers big thick trees as a nest trees, its cavities were mainly made in birches Betula sp. in Western and Southern Europe, Scots pines Pinus sylvestris in Middle and Eastern Europe and aspens Populus tremula in Northern Europe. The black woodpecker, excavating large−sized breeding cavities, is defined as a key species due to the creation of breeding sites for large secondary cavity−nesters. Because of the breeding requirements, black woodpecker can also be treated as an umbrella species for organisms associated with old trees. The way of feeding of that species shows a strong connection with the availability of dead wood. The black woodpecker is a sedentary species, which means that it is highly depended on the structure of the forest and quickly responds to changes caused by forest management. Because of the habitat requirements and relationships with other species, as well as the wide geographical range, it is a good indicator species for multifunctional suitable forest management. It can also act as a keystone species for secondary cavity nesters and umbrella species for organisms associated with old, dying trees.

Opis:
The paper describes changes, which took place over the last 30 years in old−growth forest stands occupying two permanent research plots, established in the Kaliszki and Sieraków strict protection areas in the Kampinos National Park (central Poland). Both plots have a form of ecological transects. The Kaliszki plot is 20 m wide and 700 m long (1.40 ha), while the Sieraków plot (total area of 2.56 ha) consists of two parts: main (40×460 m) and side (40×180 m) transect. In the Kaliszki plot, the stand measurements were conducted in 1993, 2007, and 2017, while in the Sieraków plot – in 1989, 1994, 2006, and 2017. For every tree with breast height diameter (DBH) 5 cm, species identity, DBH and spatial coordinates were determined. Starting from the second census, all trees which had died (‘losses’), as well as trees which exceeded the DBH threshold (‘gains’) since the previous record were noted, as well. The major tree species occurring on sample plots are Scots pine (Pinus sylvestris), pedunculate oak (Quercus robur), silver and downy birch (Betula sp.), and black alder (Alnus glutinosa). During the study period, the overall tree density declined by ca. 50%. The diminishing trends occurred for all dominant tree species. In contrast to major, dominant tree species, the demographic status of a group of minor tree species (lime, hornbeam and maple) was much more stable. One may even speak about some expansion in this case. Particularly, hornbeam density increased rapidly in the period 2006−2017 in some areas of the main transect located in the Sieraków plot. The future studies will show if this tendency will be maintained and will include other regions of sample plots. Assuming a lack of significant disturbances, one may expect that the stands growing on research plots will rather slowly change in the nearest future. Most dynamics will have a quantitative and not qualitative character. One may anticipate, for example, a growing role of pedunculate oak at the expense of Scots pine, however, considering that the two species are rather long−living, they will probably for a long time keep their dominant roles in the stand canopies.

Owing to the unpredictability of changes in a habitat, a silvicultural aim should be treated as a "vision" of the future stand and adjusted in the course of its development. To meet the rational principles of stand conversion, it is necessary to fully use the natural processes occurring in forest ecosystems. More attention should be given to the species of early succession stages, which are better adapted to the changing habitat conditions, and richer species composition should be ensured to disperse silvicultural risks.

Opis:
Scots pine forest are of the main economic importance to the forest management in lowland Europe. Large areas of spontaneous pine forest, including old−growths, are located on two vast dune belts of the Kampinos National Park (central Poland). These forests grow on oligotrophic sandy soils with deep groundwater level. This makes the area unique to study long−term changes in this type of pine forest communities. The aim of the work was to assess the changes in the species composition and richness of undergrowth of Scots pine forests at the beginning of the XXI century. The study was conducted on 10 permanent and 53 semi−permanent plots located within stands of Peucedano−Pinetum and Querco−Pinetum associations on both dune belts of Kampinos National Park. The fieldworks were performed in 2001 and 2002, and repeated in 2015 and 2018. Based on Ward’s cluster analysis we described five local forms of plant communities. Seven species groups were distinguished and changes in their richness assessed using one sample Wilcoxon test. Each species group included species characteristic and/or differentiating for a given set of syntaxonomical units. The results confirmed the hypothesis of gradual decrease of the total species richness. The median of species richness change was –0.308 species per year and was statistically significant. The changes were bigger within the local forms of the Querco−Pinetum association in comparison to Peucedano−Pinetum. The decrease was connected especially with dry grassland and heathland species (characteristic for syntaxons of Koelerio−Corynephoretea and Nardo−Callunetea classes) as well as with coniferous forest generalist species (characteristic for syntaxons of Vaccinio−Piceetea and Cladonio−Vaccinietalia). The results suggest that the two main processes shaping the species composition at the beginning of XXI century within pine forest located on the dune belts of Kampinos National Park may be identified as (i) fluctuation, and (ii) simplification, manifested by species richness decrease. This is probably connected with forest regeneration after past human use and disturbance.

This paper presents a study on a population of Pulsatilla patens conducted in 2012 in the Myszyniec Forest District in Natura 2000 area ‘Myszynieckie Bory Sasankowe’ in the Kurpie forest (NE Poland). The purpose of the study was to determine the population structure of Pulsatilla patens, especially with regard to abundance, density, and percentage of generative plants in the total population. Correlations were examined between these population features and selected environmental characteristics including ecological indicator values, community layer coverage, number of species group. For the evaluation of the linear relationship between the variables, Spearman's correlation coefficient was used. The research confirmed a significant effect of light availability, clear cuttings areas on all mean values of such indicators of plants as number of flowers, number of plants, share of vegetative and generative plants.

The study presents a system of evaluation of stand conversion needs. The system enables stand classification with regard to conversion urgency on the basis of a combination of six stand characteristics selected for their usefulness for such evaluation. These are: maturity for conversion, degree of adjustment of species composition of the regeneration to the habitat conditions, degree of coverage by a stand, degree of coverage by regeneration, degree of healthiness. The silvicultural rules adapted to the specifics in mountain regions are an integral part of the study.

Opis:
Permanently balanced forest economy demands today a resignation from a constant model of the forest stand, which preferred the productive function of the forest, mostly without any consideration to its natural values formed by Mother Nature. Implanting on Polish grounds principles of multifunctional forest districts acknowledged as a breeding object of the whole forest ecosystem, giving in that way the forest economy a proecological dimension. Its a result from a general progress of civilization and achievements in forest science; reaching towards the needs and expectations from the society gaining a general acceptation from different environments. One of the fundamental elements implementing the ecosystem is to rebuild deformed and artificially barred forest phytocenosis. This refers especially to pure pine stands on habitats, in which trophoism potential explains breeding habitats species variety. A good help for the forester in this area can be a natural succesion of good, noble broad−leaved species like for example the oak. Succesion of this species takes on a special meaning in poor habitats, in which it without any special imposes enriches the biocenose with the whole positive outcome accompanying this process; it can also be a valuable clue to the potential fertility in the habitat and the complexity in the forest vegetation community. An important task is to lead the way for the oaks development from succesion to its fullest use as a natural presence in creating the future forest generation. The article below is devoted to this question describing the natural up growth of the oak in pine stands on the coniferous forest habitats in Forest District Różanna and the methods and results in which they are used for breeding.

The influence of the edge effect on the meadow vegetation pattern was studied in the forest glades in the central part of the Middle Sudety Mts. (SW Poland). The spectacular edge effect is seen in the range of 4 m from the forest border towards the center of the glades. Within that belt we observed decrease in tree and bush species number, increase in share of graminoids and Fabaceae species, as well as increase in share of species generally related to grassland communities. A significant increase in species number and values of Shannon−Wiener diversity index was noticed within the distance of eight meters from the edges of glades.

Opis:
The study included 15 isolated islands, grouped in five size classes. Trapped individuals were identified to species and measured and weighted. The number of carabid species was higher in the ecotone zones as compared with the island interior. Reduction in total number of carabid species was observed with increasing size of an island. The share of forest related carabid species was positively correlated with the size of an island; similar was the pattern concerning the large zoophages, the European and brachypterous species. The larger an island, the higher value of the mean individual biomass index (SBO) and the index of Progressive Features Sum (SCP). With the growing size of the islands, the carabid communities are placed still further to the uppermost right hand corner in the SCP/SBO diagram (fig. 2). Response of carabid communities to different size forest islands has shown that the smallest islands which favor the establishment of stable forest communities are 0.63 ha. Hence, it is to consider in the practice of forest management to create islands not smaller than that area (this may be established at the level of about 1 ha, for the practical purposes).

Nowadays, it evolved into an oak−lime−hornbeam forest Tilio−Carpinetum betuli. The gradual replacement of Scots pine and other coniferous species into broad−leaved species is observed. Additionally, flora synanthropization and encroachment of invasive alien species (e.g. Impatiens parviflora) into the reserves was found.
