Abstract: This article aims at the valuation of the potential and economic significance of the recreational ecosystem services of forests. The research was conducted in the area of Městské lesy Hradec Králové a.s. in 2018. A part of the questionnaire survey assessed by means of statistical analysis was based on the travel cost method and the contingent valuation method, which investigate the respondents' willingness to pay for services resulting from the recreational ecosystem service of forests. The research specifically dealt with the visitors' willingness to pay for the services resulting from the use of forest logging roads, forest clearings, and small structures of forest infrastructure. The questionnaires were created using foreign publications and case studies. The findings of the questionnaire survey indicated that visitors prevailingly believed that the recreational service provided by the area of interest should not be chargeable. The reason for this opinion was mainly the fact that the visitors perceive the forests in the territory of Městské lesy Hradec Králové a.s. as public goods, hence the access to them should be free of charge.

The aim of this study is to investigate people's attitudes towards deadwood in forest. The study was carried out in the Rakhiv region (Ukraine) characterized by high importance of forest resources for the local community and economy. People's opinions were collected through the face-to-face administration of a questionnaire to 308 respondents. The survey investigated three aspects: importance of deadwood in forest; people's perceptions of positive and negative effects of deadwood in forest; effects of presence and amount of deadwood in different types of forest on people's aesthetical preferences. The results show that the majority of respondents consider deadwood as an important component of the forest, but generally they prefer intensively managed forests without deadwood. According to the respondents' opinions, the most important positive effect of deadwood is a contribution to stand dynamics, while the most important negative effect is an increasing risk of insects and diseases.

The main objective of this study was to investigate the association between driving speed and driving distance when forwarding. Data was automatically collected during 2.5 years from two large forwarders operating during final felling in central Sweden. Driving speeds for the work tasks Driving unloaded, Loading drive and Driving loaded were analysed using correlation, least-squares regression, and quantile regression. The results showed that speed and distance were strongly correlated for the work element Driving unloaded, while the correlation was weaker for Loading drive and Driving loaded. Possible factors leading to these results are as follows: longer travelling distances stimulate better planning and the establishment of better extraction roads; operators may feel stressed and drive faster as travelling distance increases; and finally, the relative influence of accelerations and decelerations decreases with increasing driving distance. Also, the use of quantile regression was successful and provided information that normal least-squares regression does not provide.

The study of erosion degradation and zoning of the southern part of the Privolzhsky Upland, limited by the interfluve of the Volga and Ilovlya rivers, with a total area of 1,156 thousand hectares, where the dissection of the gully and ravine network is 0.4-1.0 km.km-2, reaching in some places 3.5 km.km-2 was carried out by the methods of the joint analysis of digital elevation model, large-scale topographic cartographic basis and satellite images of the studied territory, using specialized programs and geographic information systems "Surfer" and "QGIS", using the developed equation (S = 240exp(-(H-98.6)2/(-2,798.4)) + 2.16), which provides a simulation in landscape analogues. Studies provide an opportunity to identify the quantitative parameters of the landscape for each of the selected contours, to determine the most vulnerable areas to erosion, which will allow us to develop a plan of work to prevent the washing away of the fertile soil layer using the example of our modelling.
