The results of the integrated assessment of prospects for use of Douglas fir (Pseudotsuga Menziesii (Mirb.) Franco) in botanical gardens and arboretums in five regions in the forest-steppe zone of Ukraine are presented. In most cases, there was a fresh fertile forest site type, and in one, there was a dry fertile site. The indicators of growth, stem quality, available seed production and self-seedlings were determined. The comparison was realized with the native species, English oak, which is traditionally grown in the regions in given forest conditions. According to the results of the integrated assessment, Douglas fir in most cases was noted a perspective species in the Ukrainian forest-steppe zone and can be used for the creation of forest plantations, protective stands, and landscaping. The climatic conditions for the regions of the study were different in the average annual rainfall and the Selyaninov’s hydrothermal coefficient.
