Sustainable management should take into account the visual impact on the landscape, as it can offer many opportunities for enhancing the aesthetic value of forests or woodlands. The effect of management options is, however, not easy to convey to decision makers and to the general public. Landscape visualisation software can help bring together the elements of a large-scale landscape project. A case study showing the effect of silvopastoral management on environmental changes in a forested area is presented. Various management options have been tested, providing a basis for discussion between partners concerning spatial organisation, such as the layout of forest and agricultural plots.
