Abstract
The paper summarizes information about forest damage development (specifically for Norway spruce) by harmful agents in the selected – most endangered areas of Slovakia (Kysuce and Orava, Tatry, Spiš, and Slovenské rudohorie). Regarding the previous forest damage short-term prognosis was established for the particular administrative units, i.e. districts. Salvage cuttings were used as an indicator of forest damage separately for abiotic agents, bark and wood borer insects, fungi and anthropic agents. Three scenarios were elaborated: optimistic, pessimistic and realistic for further development of salvage cuttings. A combination of extrapolation method and expert estimation were used for making up the prognosis. Then, yearly volume of salvage cuttings for 2008 – 2010 was predicted. The results should serve as one of base materials for preparing potential projects of forest conversions.
