Measuring the limits of uphill timber skidding with a WOODY 110 forestry tractor
Boštjan Košir, Jurij Marenče, 2007, other scientific articles

Abstract: The paper deals with the test results of uphill skidding of wood with a WOODY 110 cable skidder. The aim of the study was to find the limits of uphill skidding in relation to load size, log orientation and the slope. The trial was prepared on a test track of concave shape in the forest and with pre-designed loads of different sizes. The loads were skidded uphill once withbutt-end and then with top-end forward, until the tractor stopped because of the slope. The results show that butt-end forward skidding is more efficient. The difference between maximum loads at specific maximum slopes is almost constant (0.53 t). Proper load formation (butt-end forward if possible)is more important when skidding on steeper slopes.
Keywords: forestry, tractor, skiiding, maximum slope, maximum load

Social context as a pillar of sustainable forest management - a Slovenian case
Nevenka Bogataj, 2009, original scientific article

Abstract: Social context as more or less neglected field of sustainable development is crucial for the implementation of forest management measures. We can consider it as a basis to cope with (changing) structure characteristics. Realisation of public services, which we face when coping with economic crisis, might take this into consideration. The Forest Service network serves as a scanner of needs in their social context. It is also a respondent to local specifics in the form of forest management measures. Evidence of research on the social research in Slovenian forestry is weak, although not non-existent. We tested asystem approach, a structuring method of general public. Segmentation, a method presented, is generally known in marketing and has not been used in Slovenian forestry up to now. The two-step clustering analysis of quantitative data gathered with an inquiry of study circles (form of community learning) was used and is described herewith. The results show three general value based segments of study circle participants. The role of Slovenian foresty is changing and is not independent of its dynamic and colourful social contexts, Recognition of the society structure and dynamics may contribute to the rationalisation of organisational models during the crisis period. Hoewer, grounded actualisation of recent organisational models is possible only by considering priorities of the society's segments. We conclude with suggestion for more R&D engagement in the social pillar of multifunctional forest management, in particular as the Slovenian social context is defined by dominance of private property and forest owners' ageing, which are far from being analysed and responded to.
