The study attempts to assess the strategic position of the forest service sector companies based on the SWOT method. Positioning of the company development was done on the example of 49 companies, which are providing services for the forest management in Poznań, Piła and Szczecin Regional State Forest Directorates (western Poland). Data that enabled the analysis was obtained by the usage of the questionnaire...
The paper presents the analysis of the macro− and microelements content in the leaves, stems and roots of Vaccinium myrtillus and Vaccinium vitis−idaea as well as in the surface genetic horizons of the soils of the Słowiński National Park (SNP). The cumulative properties and translocation coefficients were characterized as well as translocation coefficients of nutritional components in bilberry sprouts...
The American mink (Neovison vison) is a species that experienced unprecedented ecological success in the 20 th century, which can be seen in both the dynamic increase in its zoogeographical range, and in its effective adaptation to ecological niches in new areas. The driving forces of this phenomenon include intensification and globalization of mink farming, which is accompanied by introduction and...
The aim of the study was to characterize the diet composition of tawny owl in relation to environmental variables: season and availability of small rodents. Study area was located in central Poland, in Łódź voivodship, in the area of Rogów Forest District. It comprised of a mosaic of forests and arable lands. The study was done in the years 2003−2010. Pellets were collected at least twice a year in...
The study presents the design of sensual didactic path at the Centre for Education and Museum (OEM) of the Roztoczański National Park (south−eastern Poland). The design work was preceded by an architectural−landscape analysis carried out in 2014. List of trees and shrubs growing in the front part was made and plant communities, which are located between the main building and the river Świerszcz, were...
The aim of this paper was to determine the dry mass content in the fresh mass of leaves, trunks or branches and in the total woody aboveground biomass of shrubs forming the undergrowth of the stands in the Niepołomice Forest (southern Poland). The variability of the dry mass content in the analysed components was determined. For the prevailing species also its correlation with the individual's height...
Improvement cuttings conducted simultaneously on a few closely located areas, often face problems about how to prepare places that would serve as temporary landings for the harvested wood. This results from insufficient wood storing space in the forest and limited accessibility of the road network to wood hauling trucks, and leads to solutions, suggesting where small landings at tree−stand edge must...
The study assessed the intensity of Polish konik browsing in mixed coniferous forest (BM), alder swamp forest (OL) and pine swamp forest (BB) of different canopy closure and shrub or ground vegetation cover. The study was conducted in Polish konik enclosure situated in the Roztoczański National Park (eastern Poland) in August 2011. We examined mean browsing intensity and the tendency of horses to...
The aim of this study was to identify the motives of visits in the Wigierski National Park (north−eastern Poland), which were focused on health and regeneration of vitality by inhabitants of Suwałki. Knowledge about the influence of forest environment on health was also investigated. The quota sampling was used to determine the sample size and number of respondents was determined proportionally to...
As the access to the fossil fuels is limited, renewable energy sources have been especially intensively promoted in recent years, namely biomass. A comparatively large amount of biomass can be obtained from forests. This refers to round wood characterized by low technical quality, small−sized wood, and logging residues. Under Polish conditions, the potential amount of logging residues is estimated...
