“…1, we would like to emphasize the role of information already obtainable by the simple visualizations presented in this study. Once derived, the preferential information could be incorporated as an objective on choice of treatments for compartments in numerical optimization (Pukkala et al 1995). Such information may become more valuable as situations where multi-attribute comparisons are required become more frequent (e.g., Pukkala et al 2011).…”

& 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.

“…El recreo es uno de los servicios ambientales más estudiados por la economía ambiental (Millward, 1993;Parsons y Keraly, 1994;Pukkala et al, 1995;Tyrvainen, 2001;Tyrvainen y Vaananen, 1998). Si bien es relativamente sencillo georreferenciar los puntos de uso recreativo, las valoraciones se centran habitualmente sobre un conjunto: un bosque, un área significativa o protegida… La cuestión es ¿cuánta superficie es realmente necesaria para que el valor del uso en el punto (o línea en caso de senderos) no varíe?…”

“…These advancements in harvest scheduling allowed for more complex analyses, such as maximum clear-cut size (Kurttila 2001;Boston & Bettinger 2001;Murray & Weintraub 2002), spatial restrictions on clear-cut opening size (Nelson & Brodie 1990;Roise 1990;Dahlin & Sallnas 1993;Richards & Gunn 2003), and the effects of different clear-cut restrictions on economic outputs (Barrett et al 1998). Spatial requirements were also considered in ecological and environmental research (Pukkala et al 1995;Hof & Bevers 2000;Kurttila 2001), optimization of wildlife habitat and timber in the managed forest ecosystems (Hof & Joyce 1993;Kašpar et al 2015), land classification strategies (Borges & Hoganson 2000), harvest clustering and reducing fragmentation (Öhman & Lamas 2003, Öhman &d Wikström 2008, and wind damage risk assessment (Lohmander & Helles 1997;Konôpka & Konôpka 2008).…”

There has been an increasing demand for environmental considerations (e.g. unharvested patches) in forest harvest scheduling in the last decades. In Slovakia and the Czech Republic, allowable cut indicators are not based on the spatial structure; thus, they are unable to incorporate these additional conditions. Many harvest scheduling models based on integer and mixed integer programming have been developed throughout the world, but their use in forest management in Slovakia and the Czech Republic is rare. These approaches have mostly been developed for clear-cut management systems and do not exist for shelterwood systems. Harvest scheduling approaches for a two-phase, small-scale shelterwood system and a clear-cut system are presented. The models also include environmental requirements that restrict area of forest stands that are not to be harvested over the planning horizon. A mathematical formulation of that requirement was integrated into the forestry decision support system Optimal to solve all analysed harvest scheduling alternatives for small-scale shelterwood and clear-cut systems. Our results indicated that the total harvest volume amounts could be higher when a two-phase, small--scale shelterwood system is applied. While there are legal adjacency constraints regulating clear-cut harvests, the influence of additional environmental requirements on the total harvested amount is more restrictive for the shelterwood system because of greater area available for harvest. Both scenarios of maximization of harvested volume and net present value provided comparable results.Key words: environmental limits; shelterwood silvicultural system; mathematical programming; adjacency constrains abstrakt V současné době stále narůstají požadavky společnosti na plnění environmentálních aspektů při procesu plánování těžeb. Těžební ukazatelé, které jsou stále ještě používány na Slovensku a v České republice, nemohou takovýto typ omezení zahrnovat, protože nejsou založeny na prostorové struktuře. Mnoho alternativních modelů plánování těžeb, které jsou založeny na celočíselném a smíšeném celočíselném programování, již bylo vyvinuto. Tyto modely jsou ale bohužel ve většině případů určeny pouze pro holosečný hospodářský způsob a modely pro podrostní hospodářský způsob stále chybí. V této práci je prezentován model plánování určený pro dvoufázovou maloploš-nou clonnou seč jako jedné z alternativ podrostního hospodářského způsobu. Model zahrnuje také environmentální aspekty, které jsou reprezentovány ponecháním dané plochy mýtních porostů bez zásahu. Uvedený matematický model byl implementován do systému podpory rozhodování Optimal, pomocí kterého byly také analyzovány všechny uvedené alternativy. Naše výsledky ukazují, že celková těžba může být vyšší v případě podrostního hospodářského způsobu. Protože jsou zahrnuty prostorové zákonné podmínky přiřazování sečí, je vliv environmentálních podmínek větší v případě holosečného hospodářského způsobu než u podrostního hospodářského způsobu. Maximalizace těžby i čisté současné ho...
