Conclusion

This study of mainly red-listed lichens presents the dispersal abilities of species and provides information about different landscape factors that affect differently at different scales. It may be difficult to determinate the effect of any particular factors on lichens. According to our results, in landscape factors only oak density was the single most important factor. So, the density of oak trees within the surrounding of lichen associated oaks seems to be an important for many red-listed species. Hence, a management plan should have to consider because density of oak trees within a stand can be increased the probability of other oaks to become colonized. Therefore, large old oaks in a landscape having different characteristics (arable, water, urban, forest) should be maintained for successful conservation of lichen species (Johansson et al. 2009). This work also highlighted the importance of spatial scale for understanding the occurrence of epiphytic lichens. In conservation, it is important to make predictions of species patterns on occurrence and richness and to do this at an appropriate spatial scale. Although, our study was limited to radii of 30-1200m, but in the area of different landscape characteristics spatial patterns of lichens may be increase the interest towards conservation of red-listed lichens at larger scales. The basic concept of this project can also be used on some other species groups including insects, fungi, bryophytes etc.
