Tree measurements (trunk diameter, tree height and crown diameter) were taken, and the trees were rated for vitality and decorativeness. The trees were found to be in a very good condition, with 89.05% of them showing no visible signs of disease. The average vitality rating was 3.94, and the average rating of decorativeness was 3.57. The results for vitality and some physical measurements exceeded values reported in the literature, suggesting that Douglas fir has adapted well to the urban environment of Belgrade. Although further research is needed, it can be concluded that Douglas fir is a suitable species for landscape planting in urban areas of Serbia. Ispitano je 179 stabala duglazije (Pseudotsuga menziesii /Mirb./ Franco) na teritoriji GO Savski venac u Beogradu, radi utvrđivanja stanja ove alohtone vrste u Srbiji i njene sposobnosti prilagođavanja urbanim sredinama. Stablima su izmerene dimenzije i ocenjena je njihova vitalnost i dekorativnost. Analizirana stabla su u vrlo dobrom stanju, pri čemu 89,05% stabala nije pokazivalo vidljive znake bolesti. Prosečna ocena vitalnosti je 3,94, a prosečna ocena dekorativnosti – 3,57. Dobijene vrednosti za vitalnost i pojedine dimenzije stabala su veće od onih navedenih u literaturi, što sugeriše da se duglazija dobro prilagodila urbanoj sredini Beograda. Premda su neophodna dalja istraživanja, na osnovu ovih rezultata, duglazija se smatra pogodnom vrstom za sadnju u urbanim sredinama Srbije Pseudotsuga menziesii (Mirb.)
