In graduation thesis we have evaluated stand structure in lowland forest of Dobrava, which was situated in the forest management unit Plešivec. Stand structure and the basal area per hectare were estimated using angle count sampling and the relascope with a basal factor slope. In the 118 forest sections, a sampling grid was set up in the form of a systematic sampling net of 100x100 m. Based on data from the forest management plans and from our field sampling we estimated the development of forest stands. In the forest ofspruce and fir the stand structure was different from the stand structure ofspruce and pine forest. The estimation of mean growing stock in the spruce and fir forest was 330 m3/ha and the share of broadleaves was greater. The differencies in the height curves were not significant in the last decade.
