Assessing visual impacts of forest operations on a landscape in the Serre Regional Park of southern Italy

摘要

Forest operations impose changes on biological, ecological, hydrological, social, and esthetic attributes of forested landscapes. Methodologies are needed to evaluate the visual impact of forest operations on landscapes as part of the planning process. We assessed the visual impact of forest operations on views from a major travel corridor within a protected area by analyzing three landscape characteristics: visibility, forest landscape quality, and visual sensitivity at distances ranging from 0 m to 5 km. A geographic information system was used to perform: (a) visibility analysis, (b) forest landscape quality analysis, (c) visual fragility analysis, and (d) landscape sensitivity analysis. The output was a landscape sensitivity map, a powerful planning tool that displays the most sensitive areas and the most sensitive forest type, in this study, specifically holm oak forest (Quercus ilex L.) managed under the coppice silvicultural system. Our results suggest some guidelines for reducing the visual impact of forest operations and demonstrate the efficacy of this methodology for designing the visual quality of forested landscapes.
