Abstract
Namen naloge je bil v pragozdu Rajhenavski Rog proučiti razvojno dinamiko vrzeli, obnovitvene cikle ter narediti terestično analizo vrzeli. Uporabljen je bil severnoameriški pristop. Rajhenavski Rog meri 51,14 ha, za analizo smo izbrali severni del pragozda (10,16 ha). Raziskavo smo opravili leta 2006 in zabeležili 87 vrzeli in 377 vrzelnikov. Prevladujejo majhne vrzeli. Pogled v zgodovino vrzeli kaže na večkratno širjenje vrzeli in njihov nepretrgan razvoj. Z analizo smo ugotovili, da ima največ vrzeli od 2 do 5 vrzelnikov. Stanje pragozda nakazuje razvoj v smeri bukovega gozda, saj delež jelke med vrzelniki narašča. Pomlajevanje poteka malopovršinsko v jedrih, kjer rastni prostor obvladuje bukev. Razvojna dinamika vrzeli povzroča nastanek malopovršinsko heterogenih sestojev. Severnoameriški pristop raziskovanja je primeren za raziskovanje razvojne dinamike. Potrebno pa je metodo izvajati natančno in jo ustrezno prilagoditi na terenu. Ugotovitve je tako mogoče upoštevati in prenesti znanje v gospodarske gozdove.

Abstract:
The purpose of the paper was to study the stand dynamic and regeneration patterns in the virgin forest Rajhenavski Rog, and to carry out a terrestrial analaysis of the gap. In order to do this, a North-American approach was used.The forest of Rajhenavski Rog measures 51,14 ha; the analysis was carriedout in the north part of Rog (10,16 ha). The research was done in 2006,whereby 87 gaps and 377 gapmakers were found. The majority of the gaps are small-sized. The history of the gaps shows their repeated widening and continuous development. The analysis showed that most of the gaps have 2 to 5 gapmakers, and that the virgin forest is in its beech spreding stage, as the percentage of fir gapmakers is rising. Regeneration is small- scale in cores, where the growing space is used by the beech. The stand dynamics of the gaps cause the occurrence of small-scale heterogeneous stands. Necessary is to work precisely and adjust work on the field. Knowledge of research is in need for transfer into management forests.
