“…For example, impacts of growth, management practices, forest (logging) operations, and locations of logging areas may affect the stakeholders' preferences on the management alternatives. It has long been recognized that even technically simple computer visualizations improve understanding of forest stand dynamics and effects of management decisions (Pukkala and Kellomäki 1988;Burkhart 1992) and facilitate eliciting the related preferences (Tahvanainen et al 2001;Karjalainen and Tyrväinen 2002). Visualization techniques and applications are reviewed in the forestry context by Mendoza et al (2006) and Falcão (2008) and techniques for extracting the decision makers' preferences from the visualizations by Kangas et al (2008).…”

“…Unless tree-wise inventory data are available, the landscapes need to be populated with trees based on less detailed inventory data. A typical approach is to simulate the locations and appearances of the individual trees based on mean diameter, height, and structure information (e.g., Karjalainen and Tyrväinen 2002). Particularly, the use of mean-based attributes and thus the requirement to simulate the trees will result in generalizations and restrictions of reality (Uusitalo and Orland 2001;Wang et al 2006).…”

& Key messageWe present a data-driven technique to visualize forest landscapes and simulate their future development according to alternative management scenarios. Gentle harvesting intensities were preferred for maintaining scenic values in a test of eliciting public's preferences based on the simulated landscapes. & Context Visualizations of future forest landscapes according to alternative management scenarios are useful for eliciting stakeholders' preferences on the alternatives. However, conventional computer visualizations require laborious tree-wise measurements or simulators to generate these observations. & Aims We describe and evaluate an alternative approach, in which the visualization is based on reconstructing forest canopy from sparse density, leaf-off airborne laser scanning data. & Methods Computational geometry was employed to generate filtrations, i.e., ordered sets of simplices belonging to the three-dimensional triangulations of the point data. An appropriate degree of filtering was determined by analyzing the topological persistence of the filtrations. The topology was further utilized to simulate changes to canopy biomass, resembling harvests with varying retention levels. Relative priorities of recreational and scenic values of the harvests were estimated based on pairwise comparisons and analytic hierarchy process (AHP). & Results The canopy elements were co-located with the tree stems measured in the field, and the visualizations derived from the entire landscape showed reasonably realistic, despite a low numerical correspondence with plot-level forest attributes. The potential and limitations to improve the proposed parameterization are discussed. & Conclusion Although the criteria to evaluate the landscape visualization and simulation models were not conclusive, the results suggest that forest scenes may be feasibly reconstructed based on data already covering broad areas and readily available for practical applications.

“…On-site visits fulfil most of the criteria for appropriate visualization methods in forest landscape preference research (Karjalainen and Tyrväinen, 2002). Sevenant and Antrop (2009) specify that being on-site implies all senses and not just visual.…”

“…The best expression is by given the respondents' proximity to the landscape. Karjalainen and Tyrväinen (2002) explain, "Movement of the viewer through the landscape is the typical way of experiencing the environment when enjoying recreation in the forest". Herrick and Rudis (1994) add interesting observation, that because respondents were interviewed at recreational areas, it is suspected that respondents may have been describing scenes in and around the interview site.…”

The development of the recreational use of forests demands a greater understanding of the profile, preferences and opinions of visitors to these forests. A questionnaire survey was hold in Cansiglio forest in northern Italy, which has become a very famous recreational area where many people come to spend their leisure time. The objective of this paper is to ascertain specifics about forest visitors, their preferences of forest structure and shape, and their other opinions, e.g. about regional problems with red deer. Results showed, among other, that almost ¼ of respondents were bikers, the rest were hikers, and the majority was from nearby cities and villages. Most of respondents go to forests from six to eleven times per year, more than ½ of them are satisfied with this frequency of forest visits. Knowing which type of forest visitors generally look for and what kind of activities they want to enjoy there is very important information and useful for management in research areas.

“…Landscape preference studies can be conducted in numerous methods such as the use of photographs (Shafer Jr and Brush 6) ; Aoki 7) ; Dearden 8) ), videos (Schroeder and Orland 9) ), and landscape simulators (Karjalainen and Tyrvainen 10) ). However, there are more limitations in using media as Abstract: Chocolate Hills is a tourist spot in Bohol, Philippines.…”
