Summary: Decreasing the mean wood skidding distance is one of the basic tasks of building forest roads in economic forests. Classical forest openness expressed in km/1000 ha, gets its real significance and actual situation regarding the forest road network quality only if it is shown in the combination with the mean skidding distance. The relative forest openness in combination with the method of bordered area also uses the mean skidding distance as one of the most important input data. What is a mean skidding distance, which types of mean skidding distances exist, how are they determined and calculated, in what way we can transform one type of mean skidding distance into another and which correction factors are used in this are only a few questions to which you can find the answer in this paper. The calculation of the optimum forest openness, as well as the calculation of the optimum mean skidding distance are based on mathematical models and once obtained values are correct, as long as the input calculation parameters are the same. Can the results of the optimum openness calculation according to mathematical models, which are based on the minimum total cost of wood skidding, be manipulated, are they extendible within determined firm boundaries and is such a starting point in a forest opening by forest roads and the total forest road network optimisation acceptable ? The paper introduces the use of the aimed wood mean skidding distance.
Key words: forest roads; opening up of forests; optimum opennes; mean skidding distance; correction factors |
