Raziskovali smo razvoj gozdnih sestojev na območju Grofije (GGE Radovljica-levi breg Save), kjer je februarja 1984 karavanški fen povzročil vetrolom, ki je razgalil gozdno območje v velikosti 270 ha. Cilj raziskave je bil analizirati razvoj poškodovanih in nepoškodovanih gozdnih sestojev po vetrolomu v obdobju 1978-2008 in ugotoviti vpliv načina obnove na razvoj gozdnih sestojev v vrzelih. Podatke smo pridobili iz podatkovnih zbirk Zavoda za gozdove Slovenije (108 stalnih vzorčnih ploskev) in s terenskim popisom. Med poškodovanimi in nepoškodovanimi sestoji smo za obdobje1978 (pred vetrolomom) do 2008 ugotovili značilne razlike v razvoju lesne zaloge, drevesne sestave in debelinske. Prav tako smo ugotovili značilne razlike med obema oblikama sanacije (naravna obnova, sadnja) v lesni zalogi, drevesni sestavi in debelinski strukturi. Naravna obnova na pretežen delu površine, mestoma kombinirana s s spopolnitveno sadnjo je najprimernejša oblika sanacije. In this study author presented development of the forests in the area GGE Radovljica % levi breg Save. We researched an area of Grofija, where in February 1984 a Karavanke foehn caused a significant damage in forests in size of a 270 ha. The aim of assessment was to determine the success of a natural restoration and afforestation on damaged and undamaged areas. Forest structure data was obtained from 108 sample plots and from terain measurements. Results showed the differences in the next stands parameters: grown stock, tree structure and DBH structure between natural and afforestation stands on affected and unaffected areas, namely between inventories in years of 1978, which was before windthrow and in the years after windthrow (1988, 1998, 2008). Research findings suggest that affected stands should have been left to the natural regeneration. In areas where that wouldn't be successful, planting is suggested. |
