Opis:
The article presents the research findings concerning the concept of forest management with regard to forest utilisation in the PEFC system. A set of developed rules of procedure in the use of non−wood forest products was presented, the observance of which was to enable the unit audited by the PEFC to meet the requirements set by the PEFC and obtain a certificate. The rules were analysed with a particular emphasis on aspects such as allowing access to stands and harvest of non−wood forest products and the factors limiting their use, harvest of forest utility plants and edible mushrooms, birch sap extraction and production of charcoal in retorts. Certification should be viewed as an integral part of the new strategy of non−wood forest use, as a tool whose effectiveness influences and will influence the development of the forest goods market and consequently the rural development.

The aim of the study was to assess the level of occupational risk on the basis of allowable maximum concentration and intensity of factors occurring in the material work environment, and to determine the relationship between the workstation and the variables describing it by drawing similarity maps using multidimensional scaling (MDS) methods. The scope of work involved four manual−mechanical wood harvesting stations characterised by nine ergonomic−technological indicators.

Widely used IT System of Polish State Forests National Holding that is currently supported with forest digital map (LMN) allows advanced processing of digital data. LMN, which contains complete information about forest in digital form, allows using computation tools for realisation of planning and projecting tasks or modeling of forest ecosystems processes. This paper presents capabilities of using Expert Systems and GIS in forestry. The usefulness and effectiveness of Expert Systems and GIS in the process of projecting of bicycle trails in forest are discussed.

The paper presents the influence of forest management on the recreational utilisation of forests. Analyses were carried out concerning the productive and recreational functions performed by managed lowland forests in the Polish lakelands. Time consumption of forest operations was calculated and individual questionnaire surveys were conducted with a representative group of 947 adult Poles as part of the studies.

Opis:
The objective of the study was to determine the size of interest in spending leisure time in forests among the residents of the Podkarpackie Province (south−eastern Poland) and to examine recreational potential of Rzeszów suburban forests. At first, basing on surveys, the demand for leisure in forests among the adult residents of the Podkarpackie Province was assessed. The survey was conducted on the random group of 439 people. Then, the recreational potential of the suburban forests of Rzeszów was assessed using own method. Almost 90% of respondents declared that they spend leisure time in forests. Most of the them rest in forests several times a year (54%), while only 9% respondents does it several times a week. The largest group among people spending their free time in forests is willing to travel up to 20 km to get to a forest. Forests suitable for recreational use cover nearly 56% of the analysed area, Among them 29% are tree stands of high or very high usability. The decrease in usability for recreational purposes predominantly results from the large share of wet habitats and dense understory. The recreational capacity calculated for Rzeszów suburban forests located within 20 km of city administrative limits amount to 1.79 man−hour/ha/day. The presented results indicate that every week 435,000 people may stay in the Podkarpackie Province forests, while approximately 43,000 – in Rzeszów suburban forests. The paper shows that there is a huge interest in spending leisure time in forests among the residents of the Podkarpackie Province, while the calculated recreational potential of Rzeszów suburban forests may be exceeded. Therefore a real risk exists that the forest environment will be damaged, moreover Rzeszów suburban forests are still poorly equipped with recreational facilities. A type of activity that counteracts this disturbing phenomenon is adequate management of recreational traffic and its balanced distribution over the areas that are naturally resistant to damages. It is also necessary to limit recreational utilisation of the forests where the calculated recreational capacity equals 0. Moreover, one should strive to boost recreational capacity of forests by their proper management.

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 paper focuses on the characterisation of forest resources and harvesting, sale and distribution of roundwood for woodworking industry, wood−derivative board production plants and pulp and paper indus−try in the Notecka Forest. The age and species structure of stands indicates that the analysed forest complex is and in the future can be an important supplier of timber for sawmills and pulp and paper mills, especially for the Wielkopolska region. The roundwood offered is of an ever more higher quality. A regular increase in proportion of trees in older age classes has caused that the Notecka Forest becomes a source of valuable timber for the sawmill and plywood industries. However, the long−term forms of cooperation between large sawmills and the State Forests Holding have to be perfected.

Opis:
Oak gall−nuts are pathological excrescences on the leaves of oaks (in Poland: Quercus robur L. and Q. petraea Liebl.) created by the Cynips quercusfolii L. The potential medical use of these non−wood forest products should be taken under consideration because of widespread use in folk medicine, but also because of the presence of gall−nuts of Middle Eastern oak species Quercus infectoria in the current Farmakopea… [2017]. The aim of this study was the preliminary analyzes of Quercus robur L. galls in the context of the diversity of the raw material and its possible consequences for the variability in tannin content, and therefore for the therapeutic value. The galls were collected in September 2018 from five living trees forming compact mid−field tree plantation in Podkarpackie Region (SE Poland). To determine the tannin content, hide powder method was used, while mass spectrometry was used for determining the identity of the raw material. The tannin content was found to be between 10.02 ±0.2% and 15.47 ±0.07%. There were no statistical differences between the tannin content of four weight groups of tested gall−nuts. The analysis of mass spectra showed the presence of gallic acid and tannin disintegration products. The results indicate that the tannin content in domestic oak galls is lower than in Quercus infectoria ones, for which less than 20% is required, however Polish galls are still the richest native tannin raw material. It was not proved that the content of tannins in oak galls was influenced by their size. A large variation in tannin content depending on the sample suggests that it might be possible to identify i.e. forest sites or climatic zones, where the obtained gall−nuts will be characterized by the high tannin content.
