Abstract
100 invasive alien species of vascular plants, the most harmful for phytodiversity on the protected areas of national importance of Ukraine, are given as a brief compendium of three lists: Black (17), Grey (50) and Watch (33). This lists 107 Біологічні системи. Т. 9. Вип. 1. 2017 are compiled on the basis of set criteria adapted to the compilation Black, Grey, and Watch (white, alarm, alert) lists, such as invasive status, species’ distribution, known or estimated environmental impact, as well as possible of management options or control measures, etc. For each species the information is provided about the group by the time of immigration, origin, way of introduction, life form, soil humidity requirement, refined types of total range, ecological and coenotic information on the occurrence in certain habitats. The participation of the studied species in the composition of plant communities, which belong to 32 classes of mainly native vegetation, was established as well as their representation in the territory of more than 50 protected areas of Ukraine of different categories and in the European lists of invasive plants. We have found that about a third of the studied species have a significant impact on the species, coenotic and ecosystem levels, and threatening to the native biodiversity of protected areas of Ukraine. The rest is a potential threat. At the same time, some alien species of Grey and Watch lists threaten native biodiversity at local or regional level in some native areas of Ukraine. They are dangerous only for certain types of natural habitats or plant communities of certain vegetation types. All of the studied species of invasive plants appeared on the territory of the studied protected areas being already naturalized and are in the process of expanding secondary range by spontaneous dispersal, the vast majority of them due to the deliberate introduction in Ukraine, it’s certain regions, or directly in the protected sites.
