Abstract
Avtor prikazuje izsledke primerjalne raziskave strukture gozdnih sestojev in rastlinske sestave v pragozdu Rajhenav in gospodarskem gozdu. V gospodarskem gozdu je mozai~nost horizontalne strukture bolj izrazita, {tevilo vrzeli in mladovij je ve~je, njihova povr{ina tudi ve~ja. V gospodarskem gozdu je ve~ kot za polovico ni`ja lesna zaloga, dele` debelega drevja in koli~ina mrtvega drevja sta ob~utno manj{a kot v pragozdu, drevesna sestava je pestrej{a, v pomladku uspeva ve~je {tevilo drevesnih vrst. Zeli{~na plast je bolje razvita v gospodarskem gozdu, kjer smo evidentirali ve~je {tevilo vrst, njihovo obiljeje v splo{nem tudi ve~je. V cikli~nem razvoju gozdnih sestojev od mladovij do debeljakov in pomlajencev se {tevilo in obilje vrst v zeli{~ni plasti pove~ujeta. Raziskava potrjuje, da je razmerje razvojnih faz gozda primeren kazalec za posredno ocenjevanje razli~nih kriterijev trajnostnega gospodarjenja z gozdovi.

Title:A comparison of stand structure and plant species composition between virgin forest remnants and managed forests, and result considerations with regard to forestry planning
Abstract:
Some results of comparisons of stand structure and plant species composition between virgin forest remnants and managed forests are presented. The horizontal structure of the analysed managed stands is more diverse and patchy, the number of canopy gaps and stand initiation patches is higher, and their average area is larger, too. In the managed forest growing stock is lessthan half of that in the virgin forest remnant, the volume of large diameter trees (DBH>50 cm) and dead trees (snags and logs) is much lower, treespecies composition is more diverse and tree species number in natural regeneration is higher compared to the virgin forest remnant. The herb layer is more abundant in the managed forest: more plant species were registered there and their abundance is greater. In the cyclical stand in development from juvenile to optimal phase the number and abundance of plant species increased. Proportion of developmental phases is a suitable indicator for assessment of different criteria of sustainable forest management.

Keywords:biodiversity, species diversity, stand structure, texture, plant diversity, managed forest, virgin forest remnant, forest planning, habitat
