The paper analyses possibilities of repeated use of Norway spruce in the regeneration of existing Norway spruce stands, in the regeneration of large-area clearcuts, and in the reconstruction of the stands of substitute tree species (Betula verrucosa) after a change in the emission situation in the northeastern Krusne hory Mts., comparing the prosperity of these plantations with plantations in the unpolluted Bohemian-Moravian Upland. The survey included 26 research plots aged 1-12 years, situated predominantly on acidic sites in Forest Altitudinal Vegetation Zones (FAVZ) 6 and 7 in the northeastern Krusne hory Mts. (air pollution damage zones A and B) and 6 control plots aged 4-11 years on acidic sites of FAVZ 6 in the Bohemian-Moravian Upland (air pollution damage zone C). The total number of characteristics assessed in each tree was up to 14. Our results indicate that the current pollution and climatic situation in the Krusne hory Mts. allow a switch to the classical spruce management system of higher elevations. The best method of regeneration is seen in smalle-size regeneration elements - clearcuts of up to 1 ha. The spruce can also be used on large-area clearcuts, but it suffers from a long transplanting shock and frost injuries there. All plantations must be protected against game damage.
