111. Stand diversity in the Dinaric fir-beech forestsMilan Kobal, David Hladnik, 2009, original scientific article Abstract: Data from forest research and permanent sampling plots were used to quantify stand structure and forest diversity in uneven-aged Dinaric silver fir and beech forest at the level of forest management unit. The study examined the indicators that are expected to be used in the monitoring of biodiversity and the favourable conservation status of forest habitat types in Natura 2000 sites. By comparing the present and past stand structures, it was possible to establish the developmental dynamics of the stands and the changes of structure indices of the forest stands on the 2-hectare research plots in the last 50 years. We adopted the indicators for the assessment of biotic and stand structure diversity based on tree species composition, stand densities, mean DBH and coefficient of variation, species and DBH-based Shannonćs index, spatial mingling and size differentiation of trees on the permanent sampling plots. The indicators confirmed stand structural diversity in four forest management classes of uneven-aged Dinaric fir-beech forests in the Leskova dolina (valley) of the Sneznik-Javorniki high Karst region. Continuous forest inventory and the presented indicators of stand structure and diversity may potentially represent the framework for the monitoring of the favourable conservation status of forest habitat types.

112. Artificial energy inputs into spruce lowland forests in suburban landscapes in SloveniaJanez Pirnat, David Hladnik, 2009, original scientific article Abstract: Slovene forestry is concerned with nature conservation, but in the past, the species variety of forests has often been changed and, similarly as elsewhere in Europe, the share of forest with artificial dominance of Norway spruce increased. Based on the spatial model of landscape structure, we estimated the arrangement in conservation of suburban forests in eight Slovene macro regions. In the area of town Kočevje, we assessed artificial energy inputs in the forests lying within one kilometre large area used by inhabitants for daily recreation. In this area, 65 % of forests were categorized as forests with artificial dominance of Norway spruce.

114. Ocenjevanje prostorske zgradbe jelovo-bukovih sestojevDavid Hladnik, 2004, original scientific article Abstract: V treh sestojih jelovo-bukovih gozdov na visokem krasu smo raziskali sestojno strukturo in njeno prostorsko zgradbo. Na treh raziskovalnih ploskvah, velikih2 ha, smo izmerili koordinate dreves ter njihove dendrometrijske znake.Raziskovalne ploskve v treh sestojih se med seboj razlikujejo po svoji zgradbi, gostotah in tudi po parametrih prostorske zgradbe, ki smo jih ocenilina podlagi metod za ocenjevanje prostorske razmestitve dreves. Za drevesa v I in II debelinskem razredu smo izračunali višje povprečne relativnerazlike v sestojnih gostotah kot za debelejša drevesa. Ko so vzorčne ploskve presegle velikost 6 a, so bile povprečne relativne razlike pri ocenjevanju števila dreves v III debelinskem razredu v vseh treh sestojih manjše od 30 % v vseh treh sestojih. Na podlagi teoretičnih modelov je bilo mogoče o šopasti rasti dreves sklepati le v sestoju s prevladujočo jelko. V dveh sestojih jelke in bukve smo določili tudi sestojne skupine, ki so jih oblikovala drevesa na površini do 0,5 ha. Za jelko, smreko in bukev smo ocenili (P<0,01), da se njihova prostorska razmestitev razlikuje od slučajnostne, te drevesne vrste pa so oblikovale tudi različno velike sestojneskupine na površini do 0,25 ha. Ker so bila dominatna drevesa v vseh treh sestojih enakomerno in slučajnostno razporejena, sklepamo, da sestoji tudi po obdobju propadanja jelke niso postali razgrajeni.
