Abstract
V diplomski nalogi se je analiziralo zgradbo sestojev in rastne značilnosti črnega gabra (Ostrya carpinifolia Scop.) na Kroparski gori. Postavilo se je 5 ploskev velikosti 1 ar. Na vseh ploskvah se je izmerilo vse drevje s prsnim premerom 5 cm ali več. Na vsaki ploskvi se je z namenom debelne analize posekalo 4 dominantne črne gabre, poleg tega pa še skupno 4 bukve in 2 hrasta.Pokazalo se je, da so gostote sestojev in temeljnice na ploskvah zelo visoke. Starostna analiza dominantnih črnih gabrov je pokazala, da pogosto presežejo starost 100 let. Višinska in debelinska rast sta bili na osojni ploskvi kljub melišču solidni, rast črnega gabra na opuščeni senožeti pa je bila izredno nagla. Ugotovljena produktivnost skrajnih rastišč je izredno nizka. Slaba polovica analiziranih dreves črnega gabra je v primeru višjih temperatur v času vegetacijske sezone tvorila ožje branike.

Abstract:
In the thesis the structure of stands and growth characteristics of hop hornbeam (Ostrya carpinifolia Scop.) is analysed. Five plots measuring 100 m2 were set. All trees with diameter at breast height of 5 cm or more were measured at each plot. Four dominant hop hornbeam trees were cut on each plot to make stem analyses. Moreover, four European beech trees and two oak trees were cut for stem analyses. According to the analysis, stand densities and stand basal areas are pretty high. The analysis of age shows that hop hornbeamoften exceeds the age of 100 years. Furthermore, the growth in height and diameter is solid on shady side in spite of scree bedrock, the growth of hop hornbeams on an abandoned meadow is very fast, and the established site productivities of extreme sites are very low. Less than half of hop hornbeam trees have narrow tree-rings as a result of higher temperatures during growing periods.
