Decorative perennials of the regional flora for recreation landscapes in the forest-steppe zone

Summary/Abstract: This work is devoted to the preservation of biodiversity and the prospects of its integration into projects for the improvement of recreational landscapes and greening facilities of modern cities. It is a continuation of the study of the bioecological potential of regional plant resources for landscaping recreational areas. To represent the existing plant diversity of the forest-steppe zone of Ukraine, a fund of species of decorative perennials was used. At this stage of the research, the decorative and bioecological characteristics of 147 herbaceous perennials of the spontaneous flora of the Feofania tract are given, which determine their economic value. The phenorhythmotypical composition, ecological and cenotic timing, colour spectrum and seasonal colour dynamics were considered. The phenorhythmotypical spectrum of this artificial population is shown, in which long-vegetating species predominate, ensuring the formation of compositions with a closed grass stand and a continuous and long-lasting decorative effect. Critical, from the point of view of competitive relationships, a group of species characterized by active dispersal is identified and options for their optimal use are presented. The ecological and cenotic diversity of the studied population, which is representative for the forest-steppe zone, is shown, which makes it possible to select the optimal multicomponent assortment for areas with different ecological conditions. The colour spectrum of the studied group and its dynamics during the growing season, which are comparable for geophilic and sciophilous species, are considered. Aconceptual approach to the selection of promising species of regional flora for the creation of decorative locations in city parks is considered. In general, the expediency of using local plant resources as an optimal source of forming a basic assortment of decorative perennials for regional landscaping isshown on the example of the study of some aspects of the aesthetic and bioecological potential of decorative perennials of the spontaneous flora of the Feofania tract. We consider the integration of the existing biodiversity of the regional flora into the architectural environment an important practical component of biodiversity conservation.
