The elimination of the trees and bushes causes disturbed patches in the forest landscapes and this can be effective on the fauna and flora. The present study deals with the activity pattern and visitation frequency of wild boars in disturbed patches of Deylaman - Dorfak non-hunting area. To do so, four disturbed patches and four closed-canopy forest environment (as the control patches) were selected and seven plots featuring 100-square-meter dimensions were taken into account and pellet groups were counted. Also, two camera traps were installed in every pair of patches (one disturbed patch and one control patch) and monitoring was carried out for five days. The results indicated that the wild boars attended the disturbed patches more than the control patch and the reason for such a preferential presence can be the food resources availability therein. On the other hand, the species activity was more of a nightly manner in the disturbed patches and it seems that this prevalent nightly activity is more due to one or several of the following factors: shortage of shelter, human interference, competition and predator - prey interactions. Therefore, the higher visitation frequency of the wild boars indicates the positive effect of the disturbed patches on this ungulate and their prevalently nocturnal activity pattern is (possibly) reflective of their negative effects. Moreover, the present study results support the creation of these disturbed patches if the forest managers especially concentrated on the protection of these patches as the important habitats of the ungulates. However, it is suggested that a proper understanding of the effects of these patches on the other species should be attained before offering any sort of management solution because unidimensional approaches in consideration of only one species and even one order can be misleading for the conservation of biodiversity in landscape-level.
