摘要: An increasing share in the forest area of European Alps has to provide protection services prevent natural hazards, such as avalanches, rock falls, erosion, and floods. Protection forests require special treatment maximize sustained mechanical stability. Although there is a significant knowledge growth characteristics silvicultural regimes for high-altitude forests, lack how suit harvest layout layout. The paper aims (1) outline management (2) an approach planning cable-based systems under those conditions, (3) discuss some typical swaths geometry patterns tending. Silvicultural interventions mainly consist laying out about two regeneration slits per hectare, which have size 0.05 hectares. engineer concurrently slit cable corridor whole area. This task very demanding, still be done manually. Defining harvests next step planning. It define spatial order tree felling relating road directions system Layout crucial minimize damages residual trees, economic efficiency operations.
