Current state and prospects of introduction of the family Rosaceae juss. species in the Precarpathian region

Abstract

The article examines the current state and prospects for the introduction of shrubs of the Rosaceae Juss. family into natural and urbanized ecosystems of the Precarpathian region. The species composition, ecological plasticity, and adaptive potential of representatives from this family are analyzed, which determine their ability to acclimatize and be used in landscaping. The main factors affecting the success of introduction are discussed, including climatic conditions, soil types, and anthropogenic impact. It has been established that the most numerous in the region are the genera Cerasus Juss., Rubus L., Rosa L. and Spiraea L., which account for approximately 70% of the total number of registered species of the Rosaceae family. Of particular interest are such species: Spiraea japonica Franch., Rosa rugosa Thunb. and Physocarpus opulifolius L., which demonstrate high decorative value and resistance to adverse environmental factors. The features of the distribution of both indigenous and introduced species, their ability to naturalize, and their potential in forming stable plant communities have been studied. It has been determined that introduced species, particularly Chaenomeles japonica Thunb., Cotoneaster horizontalis Decne., and Sorbaria sorbifolia L., effectively adapt to the conditions of the Precarpathian region, which is due to the similarity of the region's climatic characteristics to their natural habitats. The habitat analysis showed that a significant part of the Rosaceae family has a Сircumboreal or East Asian origin, which confirms their high adaptive potential. The results of the study provide the foundation for developing effective strategies for introducing ornamental species of Rosaceae into the green plantings of the Precarpathian region, which will contribute to the enrichment of biodiversity and the improvement of the ecological condition of the region.
