Vpliv gradacije podlubnikov v obdobju 2002-2005 na delež smreke v nižinskih gozdovih celjske kotline : graduation thesis - higher professional studies

Preložnik, Uroš (author), Bončina, Andrej (mentor)

Nižinski antropogeno zasmrečeni gozdovi so pomemben del Celjske kotline. V zadnjem desetletju je prišlo do večletne zaporedne gradacije podlubnikov. Ti so se namnožili predvsem zaradi spremenljivih klimatskih razmer. S svojo namnožitvijo so ustvarili precejšnjo gospodarsko škodo. V diplomski nalogi je predstavljena dinamika sanitarne sečnje v obdobju od leta 2002-2005. Prikazan je vpliv gradacije smrekovih podlubnikov na delež smreke v lesni zalogi in na skupno lesno zalogo na preučevanem območju. Ugotovljeno je, da se delež smreke v sestojih zmanjšuje.

Abstract

Lowland anthropogenic spruce forests, present an important part of Celje basin. In last decade, a sequential gradation of bark beetles has occurred several years. They have multiplied, because of changed climate conditions. Byits proliferation they have coused a considerable economic loss. In this graduation thesis we were monitoring dynamics of sanitary felling in the period 2002-2005. We studied the impact of spruce bark beetles gradation on the share of spruce in total growing stock in the studied area. We found out that the share of spruce in total growing stock has decreased.
