In the Slovak part of the outbreak practices consisted of no action prior to 1994 intensive pest control management trap trees insecticides salvage cutting from 1995-1996 active differentiated approach control measures according to the zonation of attacked stands combined with intensive use of pheromone traps from 1997-1998. In Poland the outbreak was mostly located in reserve areas where pest management or other activities were prohibited. Despite the use of intensive pest management measures tree mortality was not significantly decreased in the Slovak region during the peak outbreak years of 1995 and 1996. Classical forest protection led to an increase in attractiveness of forest edges to bark beetles which could disperse to these areas from locations where no control measures were practiced. Unfavourable weather for bark beetles led to a rapid decrease in tree mortality in both parts of the study area.
