The structure, state and productivity of massive forest plantations in Kuban steppe are specified by the morphology and biological-ecological properties of species-edifiers, forest-growing conditions, a set of the dominant and admixed trees, technological methods of establishing the plantations, and by a scheme of their mixing and distribution. The phytocenotic structure of these forests is characterized by a variety of different forest types where three kinds of light structure are observed: semi-light, semi-shadow, and shadow. The species composition of the artificial forests includes 34 tree species and 13 species of shrubs of European, Asian, Euro-Asiatic, and North American floras. The main edifiers of the forests are Quercus robur, Fraxinus excelsior, F. lanceolata, Robinia pseudoacacia, and Juglans nigra. The best indices of the vital state were registered in 100-year-old plantations of Q. robur and F. excelsior that were grown and carefully tended. The development of undergrowth, regrowth, and living ground cover is determined by the effect of the stand. The results obtained characterize the current state of the cultural phytocenoses and directions of their further development.
