The aim of the article is a description of a methodical procedure which would enable to determine the market value of the recreational function of forests in the case of creation of real market demand. The methodical approach was verified on a case study in the chosen area. Results imply that determination of the market price of the recreational function in the case of creation of real market demand is possible and the formulated hypothesis is not rejected. The final rental value in the closed time period from the price determined for forest lands by application of the nominal interest rate 4.75% is 0.169 CZK.m-2. The procedure can be understood as a theoretical and methodical tool usable in the valuation practice, but especially as a political tool in the creation of legislative regulations in the area of valuation of ecosystem forest functions and services at the national and international level.

The main objective of this research was to clarify the potential of using a low cost hand-held camera for evaluation of the stem accuracy reconstruction, through the comparison of data from two different point clouds. The first cloud comprises data collected with a digital camera that are compared with those collected by direct measurement of the FARO® Focus3D S120 laser scanner. Photos were taken in a circular plot of pine trees using the stop-and-go method. We estimated the Euclidean distance for corresponding points for both clouds and we found out that most of the points with error less than 11 cm are concentrated mainly on the ground. Regression analysis showed a significant relationship between height above ground and error, the error is more pronounced for points located higher on the stems. As expected, no dependence was found between the error of the points and the diameter at breast height of their respective stems.

Recently, the international scientific literature focused on the concept of ecosystem services. The substantial difference between forest functions and ecosystem services is that the former implies the capacity of forest ecosystem to supply goods and services to society, the latter focuses on the benefits that people obtain from the ecosystems. The aim of this paper is to analyse the social perception of the importance of forest functions and threats to forest multifunctionality in four case studies in the south of Italy, in the Calabria Region (Pollino, Sila, Catena Costiera and Serre Calabre). The study was structured in four steps: (i) stakeholder analysis, (ii) questionnaire survey, (iii) statistical analysis of the collected data, (iv) development of importance-threat matrices. At the end of the analysis, 71 representative stakeholders were identified and involved in the survey. Besides, the representative stakeholders were classified into four groups of interest according to their characteristics: public administrations, associations-non-governmental organizations, academia and research institutes, professional associations of the forest-wood-energy chain. The stakeholders assigned a level of importance to nine forest functions and to ten threats to multifunctionality using a 5-point Likert scale. The data analysis was elaborated distinguishing between groups of interest and case study areas. The overall results show that the two forest functions perceived as the most important by the involved stakeholders are biodiversity and landscape conservation, while a low importance was assigned to the productive forest functions. Regarding the threats, the overall results show that the most relevant threats are the forest fires that affect all functions followed by illegal cuttings and forest abandonment. The ranking of forest functions is similar in all four case studies, while the threat evaluations are more linked to local contexts.

There are different expectations and priorities among stakeholder groups. The object of the research is the case study area in the Goat Backs Mountains in Slovakia (representing Western Carpathians). The stakeholders' panel which included local government officials, landowners, foresters, interest group representatives etc. judged the current and future importance of ecosystem services in a special questionnaire. The context analysis provided main strengths and weaknesses, threats and opportunities that influence mountain forest management and the provision and use of ecosystem services in the case study area were done by involved experts from practice and science. Based on the SWOT results a possible strategy for the provision of ecosystem services was proposed. Some of the key issues that have been identified by experts concerning the balancing of ecosystem service provision are: strengthening the local stakeholder involvement; enhancing regional initiatives; and economic market-oriented instruments and economic incentives.
