The first field investigation was performed in 1980 and 1981, and the second in 2013 and 2014. The main goal was to perform a landscape typology in order to assess the susceptibility of landscape complexes to occurrence of anthropogenic and natural destruction processes and to assess the condition and prospects of HTs and their impacts on the adjacent alpine environment. Landscape complexes were characterised by selected abiotic, biotic and technical parameters of HTs and their impact zones. Due to the high variability of these parameters over the length of the HTs, we had to decide on how to map them. This was done using a square grid with 100 m-sized cells. For each cell with HT, the parameters were assigned the typical value within that cell. In total, 26.3 km of HT were studied, stretching over 266 grid cells. On comparison of the two data sets, it was seen that, 64%(171 grid cells) display a generally positive condition, with 54%(143 grid cells) even exhibiting significant improvement or continuously positive state of their condition. 36%(95 grid cells) were in bad condition, including 3%(9 grid cells) whose state had deteriorated, and 2%(6 grid cells) whose state had significantly deteriorated, in the time between the two assessments.展开更多
