The paper presents the results of a study of environmental conditions, morphometric tree properties and the quality of an artificially-established stand of white ash (Fraxinus excelsior L.) in the suburban zone of the city of Belgrade. The investigated stand belongs to special-purpose forests and forms part of the ‘Lipovica Forest - Dugi rt’ Protected Natural Area. The site is typologically classified as а typical forest of Hungarian oak and Turkey oak (Quercetum frainetto-cerridis typicum) on brown lessive soils. A detailed assessment of morphometric properties of the white ash trees indicate the predominant participation of trees whose relative length of crowns is more than half or half the total height of the tree (98%), high share of full-boled trees (68%), with good to excellent clearness (84%) and straightness (66%) of the stem. The quality of the stand is determined through the assessment of the crown classes, stem and crown quality. Dominant and co-dominant trees account for 94% of the stand trees with a sufficient number of trees that can be function carriers. The health state of the stand is satisfactory, with no visible signs of phytopathological and entomological diseases or mechanical injury. The research has pointed to the good effects of the introduced species of noble broadleaves on the artificial regeneration of the forest ecosystems established on the site of Hungarian oak and Turkey oak as special-purpose forests.
