Učinki nege na višinsko priraščanje osebkov v mladju in gošči v podgorskih bukovjih

Jerman, Žiga (avtor), Klopčič, Matija (mentor)

Na rastiščih podgorskega bukovja v Zasavju smo na dveh raziskovalnih objektih v razvojnih fazah mladja in gošče izvedli nego ter nato preučevali učinke nege mladja in gošče na višinsko in debelinsko priraščanje dreves različnih drevesnih vrst. Raziskovalni objekt je obsegal 10 ploskev velikosti 25 m2 v mladju in 32 ploskev velikosti 25 m2 v gošči, na polovici ploskev v obeh objektih smo leta 2021 izvedli nego. V gošči smo merili tri zaporedne višinske in debelinske prirastke 160 drevesom, v mladju pa tri zaporedne višinske prirastke 90 drevesom različnih drevesnih vrst. Ugotovili smo statistično značilne razlike v višinskem priraščanju negovanih in nenegovanih dreves v mladju in v gošči. Negovana drevesa so svoj višinski prirastek povečala v večji meri kot nenegovana drevesa. Drevesne vrste so se različno odzivale na negovalne ukrepe, med vrstami smo ugotovili statistično značilne razlike v priraščanju v višino. V mladju smo največje višinske prirastke zabeležili pri bukvi, v gošči je najhitreje v višino priraščala divja češnja. Negovana drevesa so največje višinske prirastke izkazala v drugem letu po izvedbi nege. Pri drevesih v gošči nismo ugotovili statistično značilnih razlik v debelinski rasti med negovanimi in nenegovanimi drevesi. Dokazali smo, da nega značilno vpliva na višinsko priraščanje dreves, kar je pomembno znanje za ustrezno upravljanje in usmerjanje razvoja gozdnih sestojev.

• Naslov: The effects of silvicultural measures on height growth of trees in regeneration and thicket stands in the submontane European beech forests.

Izvleček

In two study sites in the submountain European beech forests in the Zasavje region, tending was carried out in the regeneration and thicket stands and the effects of the silvicultural treatment on the height and diameter growth of individual trees of different tree species were explored. The study sites consisted of 10 plots in the regeneration and 32 plots (25 m2 each) in the thicket, in 2021 half of the plots in both study sites were treated with tending. In the thicket, we measured height and diameter increments of 160 trees for three consecutive years, while in the regeneration only height increments of 90 trees of different tree species were measured for three consecutive years. We found statistically significant differences in the height increment between treated and untreated trees in the regeneration and in the thicket. Treated trees increased their height increment to a greater extent than the untreated trees. Tree species responded differently to the tending measures, and statistically significant differences in the height increment were found between species. In the regeneration, the highest height increments were recorded for beech, while in the thicket wild cherry exhibited the highest height increment. The treated trees showed the highest height increments in the second year after treatment. For trees in the thicket, we found no statistically significant differences in the diameter growth between the treated and untreated trees. We have shown that the tending treatment has a significant effect on height growth of trees, which is important knowledge for the proper management of forest stands.
