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.

Title:Sestojna raznovrstnost v dinarskih jelovo-bukovih gozdovih
Abstract:
Na podlagi podatkov gozdarskih raziskovalnih ploskev in stalnih vzorčnih ploskev smo ocenili zgradbo in pestrost v dinarskih jelovo-bukovih gozdovih naravni gozdnogospodarske enote. Predstavljeni so kazalniki, ki bi jih lahko uporabili za ocenjevanje raznovrstnosti in ugodnega ohranitvenega stanja gozdnih habitatnih tipov na obmoèjih Natura 2000. Na podlagi primerjave danasnje in nekdanje sestojne zgradbe na 2 hektarskih raziskovalnih ploskvah je bilo mogoče oceniti razvojno dinamiko in spremembe strukturnih znakov gozdnih sestojev v zadnjih 50 letih. Na stalnih vzorčnih ploskvah smo uporabili kazalnike za ocenjevanje biotske in strukturne raznovrstnosti gozdnih sestojev na podlagi sestave drevesnih vrst, sestojnih gostot, povprečnih premerov in koeficientov variacije za premere dreves, Shannonovega indeksa za vrstno pestrost in debelinsko strukturo dreves, prostorsko razmestitev mesanosti in dominantnosti drevesnih vrst. S kazalniki smo potrdili razlike v zgradbi gozdnih sestojev stirih gozdnogospodarskih razredov, ki obsegajo raznodobne dinarske jelovo-bukove gozdove v Leskovi dolini na območju Snežniško-Javorniškega masiva. Stalne vzorène ploskve in predstavljeni kazalniki sestojne zgradbe in raznovrstnosti bi lahko postali izhodišče za monitoring ugodnega ohranitvenega stanja gozdnih habitatnih tipov.
