Decorative Adventive Species of Trees and Shrubs of the Crimea

Adventitious plants are plants that have taken root in a place that does not correspond to their area of origin due to anthropogenic impact, and therefore they are all wild species that were created only with human help, unlike native species The results of the study of adventitious woody plants of the urban flora of the Republic of Crimea, Russia are presented. The composition of adventitious flora species has been determined, and their ecologobiological properties have been studied. 162 species of adventitious species from 49 families have been identified in the flora of the Republic of Crimea, which is about 43% of the total species composition of the peninsula. The adventitious flora in all parts of the world is very diverse, and its expansion is a rapidly growing process that has a global character and entails a chain of negative consequences. The scale of the adventitious component's impact on nature does not entail the need for special study of its composition, properties and development trends A comprehensive study of the adventitious species of the Republic of Crimea seems relevant as a starting point for monitoring the invasion of adventitious species.
