As a consequence of budget constraints and the fact that the present forest planning system of the State Forest Administration of Baden-Württemberg has been in operation since 2000, this system has to be developed further. Since the group of forest officers at the county level is the largest user group, it was decided to start a participatory process in order to derive the most relevant requirements of that group. A survey within the board of managing directors followed. In order to gain an insight into the requirements and preferences we used the pairwise comparison method. The paper highlights the preference structure in respect to (1) the goals of FMP, (2) target groups, (3) the FMP process, (4) tasks, (5) and the outputs of FMP. It can be shown that the average percipience of FMP of forest officers tends to be more traditional and internal than proactive and stakeholder-oriented. The pairwise comparison approach has been proven successful as a means to get insight in the preference structures.","PeriodicalId":53620,"journal":{"name":"Acta Silvatica et Lignaria Hungarica","volume":"10 1","pages":"75 - 88"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89505309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main factors influencing forest resource management are site (which can be modified by climate change) and the corresponding species or stand type. Based on these possibilities, close-tonature forest management can be evaluated on a more realistic basis.

Quite frequently, this goal is flanked by an indicator, mostly a so-called employee satisfaction index, which is frequently derived from an employee satisfaction survey (ESS). On one hand such a survey has to reflect the characteristics and structure of the enterprises, on the other hand it is known that the question for intercompany-comparison turns up immediately after the disclosure of the results. The paper discusses the results of a meta-analysis of ESS in seven of the larger forest enterprises in Germany. The main topics are underlined and the problems of comparability of customized ESS are shown, while focusing on both wording and scales used for their measurement. A methodological approach of dealing with various scales is discussed based on the results of inter- and intra-company ESS. A vision of a common ESS framework is outlined.","PeriodicalId":53620,"journal":{"name":"Acta Silvatica et Lignaria Hungarica","volume":"62 1","pages":"102 - 89"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88150702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The perceptions of forests, sustainable management, and ecosystem services were studied through two surveys. The general public and forest owners were the two target groups. The questionnaires had similar questions, though two different methodological approaches were used - the CATI system, for general public opinion survey, and semi-structured questionnaires for forest owners. The second survey contained more detailed questions regarding forest properties. Combined answers from 1503 respondents from the general public and 150 forest owners were evaluated on the following topics: sustainable forestry, major ecosystem services, and perceptions of forests. The majority of the Slovakian public regards ecological values as the most important element, whereas forest owners prefer the economic purposes for the maintenance and enhancement of forests. Forest owners tend to visit their forests once per week, whereas the general public tend to visit only once per month. The main cause for this non-attendance in the general public was a lack of recreational time, followed by a disinterest in forests. The main purpose for visiting forests for both groups was recreation. Overall, it can be concluded that people are mostly satisfied with forest management in Slovakia. Forest owners are satisfied with their forest properties, and plan to keep them for their children. In the future, more attention should be focused on investigating the younger generation’s perception of forests.","PeriodicalId":53620,"journal":{"name":"Acta Silvatica et Lignaria Hungarica","volume":"105 1","pages":"23 - 34"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79283299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To successfully adapt to these changes, landowners’ knowledge framework must change. Washington State University Extension has been offering comprehensive, multi-week training courses for small-scale forest owners. From 2008 - 2013, participants were surveyed at the conclusion of the training, one year following the training, and again at three years following the training. These follow-up surveys demonstrate a progression from knowledge change to behaviour (management) change and, ultimately, to condition change. Condition changes included increased wildlife diversity, decreased invasive species cover, and increased economic sustainability. The results demonstrate that changing a landowner’s knowledge framework through education is a highlyeffective approach for helping them successfully adapt to changing external framework conditions.","PeriodicalId":53620,"journal":{"name":"Acta Silvatica et Lignaria Hungarica","volume":"66 1","pages":"35 - 46"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74522132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Principles and methods from other fields of science form the basis of these techniques. Electrical impedance measurement, which is adopted mainly from applied geophysics, plays an important role in the investigation of living trees and wood material. Unlike other measurement techniques that provide mainly physical information, electrical impedance measurement is able to gather either physical or chemical information. There are several published accounts of the use of Electrical Impedance Tomography mainly for examining internal decay, estimation of sapwood, and heartwood width. The advantages of the method are its low costs and rapid execution; however, low spatial resolution is still one of the most glaring limits of the method. Use of a new, self-developed, high resolution measurement system provides new opportunities to gain better insights into the characterisation of wood material. As well as high accuracy and resolution, the measurement system is able to operate in a wide frequency range. This expands the examined parameters making it possible to extend the gained information and develop new methods for the investigation of living trees and wood material. The aim of our publication is to introduce some experimental results in the investigation of spatial resolution our system measured on a wooden disc.

The aim of the field research was to verify published data on the occurrence of a woodland of Upper Mountain Norway spruce (association Polysticho-Piceetum) in the territory of Vysoke skalky. A field study in the area has revealed that most of published data on the occurrence of the Kulczyński’s Picea woodland are incorrect, as its real upper altitudinal limit reaches ± 940 m. The main result is the confirmation of the real existence of a Vaccinium myrtillus-Homogyne alpina-Picea abies phytocoenosis in the territory of Vysoke skalky.
