1. Anić: PROMJENA SASTOJINSKOG OBLIKA PRIRODNIM POMLAĐIVANJEM NA PRIMJERU.. Šumarski list SUPLEMENT (2003), 41-49 ing the possibility of converting the stand form by natural regeneration and recommending a suitable regeneration method. The experiment was established in three sample plots: in an unthinned stand, in a thinned stand and over a bare regeneration area. The structure of old Black pine stands was analysed, as well as the species, quantity, age, heights and quantitative properties of natural young growth. It was found that old forest cultures of Black pine in the studied localities of Senjska Draga have all the characteristics of a transitional forest. The analyses of natural young growth indicate the possibility of converting the transitional into the final forest (climatogenous forest) of pubescent oak with manna ash and hornbeam. Thinning of old black pine monocultures results in two-storey stands with mature trees of black pine in the upper storey and an undergrowth of deciduous species in the lower storey. The bare regeneration areaon the one hand and a thick crown cover of unthinned stand of black pine on the other, hinder the regeneration of pubescent oak. Stand form conversion by natural regeneration in the studied sites can be accomplished by applying shelterwood cutting over small areas.
