Razvoj gozdnih sestojev na nekdanjih novinah v Koprivni

Golob, Janez (author), Hladnik, David (mentor)

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. Na raziskovalnih ploskvah smo določili lesno zalogo, temeljnico in debelinsko strukturo. Lesna zaloga se giblje od 566,41 m3/ha do 761,30 m3/ha, temeljnica pa od 48,68 m2/ha do 61,67 m2/ha. Opazili smo skokovito povečanje višinskih krivulj v sestojih. Delež smreke v lesni zalogi se je v zadnjih 60 letih povečal za več kot 20 %. Delež dreves z veliko vitalnostjo pa se je povečal za 20 %. Prav tako se je povečala kakovost debla dreves. Predstavili smo horizontalno razmestitev dreves na ploskvah ter jo primerjali s horizontalno razmestitvijo dreves leta 1990. Z uporabo javno dostopnih podatkov laserskega skeniranja Slovenije (2015) smo predstavili tudi vertikalno zgradbo sestojev na ploskvah.

• Title: Development of forest stands on former slash and burn farming areas in Koprivna

Abstract

The permanent research plots, located in the former slash-and-burn areas in the cadastral community of Koprivna were remeasured for the sixth time. The forests on the research plots are privately owned and after research plots have been established in 1960, no significant forest management occurred. On the research plots the growing stock, basal area and diameter structure have been estimated. Growing stock ranges from 566.41 m3/ha to 761.30 m3/ha. Basel area ranges from 48.68 m2/ha to 61.67 m2/ha. As compared to previous available measurements, the significant raise of forest stand height curves has been determined. The share of Norway spruce in growing stock has increased by more than 20 % in the last 60 years. As compared to the previous years, the share of high vital trees increased by 20 %. Also the stem quality of the trees have increased. Historic forest cover has been compared to the current forest cover. In addition, the vertical stand structure on the research plots was obtained and presented by using publicly available information Laser scanning of Slovenia (2015).
