An optional leisure activity in forest areas for mountainbikers is the subject of discussion in this article. Cycling has become a popular leisure time activity, not only in the Czech Republic but internationally. A bicycle offers the user an unparalleled freedom that seems to have great appeal in these globalized, modern times. A singletrail is a narrow single-directional path for mountain bicycles in the landscape, in contrast to the two-lane forest roads mainly intended for the industrial purposes of forest management. The singletrails of Moravský kras (Moravian Karst) are built on the land owned by the Mendel University in Brno (Masaryk Forest Enterprise Křtiny) near the Jedovnice municipality of the Czech Republic. The aim of the article is to assess the attendance of the area using automatic counters, and to analyse the results, especially according to the illegal transits in the area of interest. The preferences of visitors were evaluated using questionnaires as well. Hypotheses were defined, and the chi-square test and Mann-Whitney testing methods were used to validate or improve them. Separate preferences for men and women were analysed in order to detect the differences or similarities of preferences. According to the results, women notably prefer the medium to easiest level of difficulty of the trails while men mainly prefer the trails of medium difficulty, although they use the most difficult trails too. Contact with nature is important for both the target groups. Training on singletrails is not as important for women as for men, but physical activity is very important to both groups. Women mainly ride on the singletrails for the joy of movement, which they consider to be a more important reason than men. The results of this study will be used to improve the area for mountainbikers as well as singletrail design for newly planned areas. Both human preferences and environmental needs will be taken into account.

In an upland forested micro-catchment during the growing season, we tested soil responses to precipitation events as well as soil water content (SWC). We asked ourselves if what is the difference of SWC response to precipitation events depending on the presence and proximity of a tree? The environmental heterogeneity of the small 7.5-ha headwater area was captured by soil probes at specific locations: (i) probe measurements of SWC at 10-, 30-, 60-, and 100-cm depths; (ii) resolution of near-tree (NT) and between-tree (BT) positions; and (iii) resolution of four slope classes. The results revealed significant differences between the hydrological responses of the soil. NT soils had faster infiltration but were also faster to dry out when compared to BT soils, which were less affected by the presence of trees. Water input threshold values, measured as the precipitation amount needed to cause a significant increase in SWC, were also significantly different, with NT positions always lower than BT positions. Total infiltration of the topmost NT and BT soil layers reached 185 and 156 mm during the study period, corresponding to 43% and 36% of the total 434 mm of precipitation, respectively. Infiltration into the deepest horizon was significantly higher in NT soils, where it reached 114 mm (26%) as opposed to 9 mm (2%) in BT soils, and was indicative of significant vertical hydraulic bypass flow in the proximity of trees. These observations contribute to better understanding the hydrological processes, their nonlinearity, and the expansion of conceptual hydrological models.

The article is on the effects of woody vegetation growing on the roadside on the temperature of the surface of cycle paths. The main hypothesis of the study is that vegetation has the effect of lowering the temperature of the surroundings in its shadow and thus improves the comfort of users of cycle paths in the summer months. The second hypothesis is to find out which type of road surface is most suitable for the thermal well-being of users. This goal was achieved by measuring the temperature of selected locations on cycle paths with different types of construction surfaces with nearby woody vegetation using a contactless thermometer over several days at regular intervals. The positions of the selected locations were measured using GNSS and the whole locality of interest was photographed using an unmanned aerial vehicle (UAV), or drone, and subsequently a digital surface model (DSM) of the area was created using a Structure from Motion (SfM) algorithm. This model served for the calculation of incident solar radiation during the selected days using the Solar Area Graphics tool with ArcGIS software. Subsequently, the effect of the shade of the surrounding vegetation on the temperature during the day was analysed and statistically evaluated. The results are presented in many graphs and their interpretation used to evaluate the effects of nearby woody vegetation and the type of road surface on the surrounding air temperature and the comfort of users of these routes. The results demonstrate the benefits of using UAVs for the purpose of modelling the course of solar radiation during the day, showing the effect of roadside vegetation on reducing the surface temperature of the earth’s surface and thus confirming the need for planting and maintaining such vegetation.
