Current use of European beech (Fagus sylvatica L.) for artificial regeneration of forests in the air-polluted areas

Abstract

The paper deals with the use of European beech in the reconstruction of substitute species stands and in the regeneration of existing spruce stands in the air-polluted region of the north-eastern Krušné hory Mts. (air-pollution damage zones A, B, forest altitudinal vegetation zones 6 and 7, acidophilic sites). Twenty stand situations were analyzed during the study. The study objective was to compare the growth of European beech plantations in the Krušné hory Mts. with the growth of plantations of the same age in similar sites in the unpolluted region of the Bohemian-Moravian Upland (air-pollution damage zones C, D, forest altitudinal vegetation zone 6, acidophilic site). Each plant was assessed for eight growth and visually classified parameters and traits. Results of the survey showed that in the existing air-pollution and climatic situation, it is possible to switch to normal (shelterwood) beech management of higher elevations in the north-eastern Krušné hory Mts. The stands of substitute species and the current stands of Norway spruce may effectively eliminate injuries caused by late frost.
