In this study we analyse the effects of the cycle and hiking trails on the abundance, spatial activity and behaviour of roe deer and wild boar. We found low effect of disturbance on the presence and density of roe deer and wild boar population. The density of ungulates was more affected by the development of shrub layer than by human activities. In areas with low intensity of disturbance, density of roe deer beds was lower than in heavily disturbed areas. The identical course of activity in the areas indicates that the roe deer is under significant pressure from the disturbance both in the disturbed and undisturbed area. As expected, the human impact on the wild boar was greatest in one of the heavily disturbed area, but at the same time this species used the most heavily disturbed area the most. In both types of areas, the wild boar maintained strictly nocturnal activity, which demonstrates the significant effect of human interference in both disturbed and undisturbed areas. Forests in the vicinity of municipalities and in the areas attractive for tourists are important with respect to their recreational function. The characteristic feature of these suburban forests is the high intensity of recreational use, which is manifested by year-round use, a high attendance in the forest area, human activity performed even at night, and the concurrence of several recreational activities at once. In addition, the visitor loads may also affect disturbance-sensitive animal populations. The impacts of tourism on animals will differ significantly for individual species, especially depending on their tolerance to disturbance, ability to hidden life, possibility of switch to a nocturnal lifestyle etc. The absence or lower intensity of hunting pressure, which is very problematic or even impossible in human-used forests, will also have some relevance. The aim of this study was to determine the effects of the presence of cycle and hiking trails on the abundance, spatial activity and behaviour of roe deer (Capreolus capreolus). We tested the following hypotheses: 1. The high intensity of tourist activities will have a negative impact on the density of large animals. 2. The distribution of roe deer will be uneven in suburban forests, the animals will stay in an area with a lower intensity of disturbing factors and their activity will be exclusively nocturnal. In the suburban forests near Brno (South Moravia), four areas with different intensity of human disturbance and the presence of cycle trails were distinguished (Fig. 1; Tab. 1). Monitoring of residence signs was carried out on transects (5m wide) that evenly covered all four areas. In two selected areas, animals were monitored through 14 camera traps (7 camera traps in each area). Density of studied species in the areas was estimated by the Random Encounter Model method. The numbers of roe deer and wild boar were significantly higher in disturbed area with trail than in the peaceful area. At the same time, there was a well-developed shrub layer in the disturbed area, which was almost absent in the peaceful area (Tab. 2). The intensity of the disturbance affected the behaviour of the roe deer, which was reflected in the ratio between the number of marking places and the number of beds. In peaceful areas, roe deer formed more beds than in disturbed areas. The daily rhythm of the roe deer activity was the same in the disturbed and peaceful area. Activity in both areas was concentrated until dawn and dusk (Fig. 2). This two-peak activity is not typical for roe deer. The identical course of activity in our localities indicates that the roe deer is under significant pressure in the disturbed and peaceful areas. No significant difference was found between the daily activity of the wild boar in the disturbed area and in the peaceful area (Fig. 3). In both types of areas, the wild boar maintained strictly nocturnal activity, which demonstrates the significant effect of human interference in both disturbed and peaceful areas. The recorded density of these species in selected areas was higher than in other European countries (Tab. 3). [ABSTRACT FROM AUTHOR]
