Structure of the alien flora fraction of the “Yalta Mountain-Forest” Nature Reserve
Over the past few decades, the study of the problem of biological invasions has been attributed to environmental and economic security issues in many countries, including in Russia and on the territory of the Crimea. The Crimean Peninsula, located in the south of Eastern Europe, is one of the centers of plant biodiversity. Species occurring in protected areas require special attention. The paper, taking into account the modern botanical nomenclature, provides an expanded list of invasive species on the territory of the: “Yalta Mountain Forest” Nature Reserve, including 102 species from 83 genera, 37 families. A comprehensive analysis of the taxonomic, biomorphological, ecological structure of the aliens fraction of flora has been carried out. The features of the alien component in terms of time, methods of appearance, origin, degree of naturalization of species in the protected area are established.
