Razvoj gozdnih sestojev na nekdanjih novinah v Koprivni

Abstract

Na raziskovalnih ploskvah, ki ležijo na nekdanjih novinah na območju katastrske občine Koprivna, smo v septembru leta 2017 opravili šesto zaporedno polno izmero. Gozdovi na raziskovalnih ploskvah so v zasebni lasti in na njih od vzpostavitve le-teh v letu 1960 niso gospodarili. V naravnem sukcesijskem razvoju, ki se je začel pred 70 oziroma 100 leti, je na ploskvah prevladala smreka, spreminjanje sestojnih gostot bi lahko primerjali z Reinekejevem pravilom (SDI) o gostoti sestojev in samoizločanju dreves. Na raziskovalnih ploskvah se lesna zaloga giblje od 566,4 m3/ha do 761,3 m3/ha, temeljnica pa od 48,7 m2/ha do 61,7 m2/ha. Opazili smo skokovito povečanje višinskih krivulj smreke in macesna v sestojih. V neredčenih sestojih prevladujejo drevesa z visokimi neugodnimi vrednostmi dimenzijskega razmerja h/d.

Secondary title:	Development of forest stands on former slash and burn farming areas in Koprivna
Secondary abstract:	We conducted the sixth consecutive measurement of permanent research plots located in former slash-and-burn areas in the cadastral community of Koprivna. The forests on the research plots are privately owned and have not been subjected to significant forest management since their establishement in 1960. Natural succession, which began 70 or 100 years ago, was dominated by Norway spruce. The study shows that in untreated Norway spruce stands, the estimation of changes and the self-thinning process are comparable to Reineke%s self-thinning rule or Stand Density Index (SDI). In the research plots, the growing stock ranges from 566.4 m3/ha to 761.3 m3/ha, and basal area ranges from 48.7 m2/ha to 61.7 m2/ha. When comparing our results to previous available measurements, we observed a significant increase in forest stand height curves. In untreated stands without thinning operations, the predominant proportion of trees had a high and unfavourable height-diameter ratio (h/d).
