Synanthropic vegetation are the product of anthropogenic activity. They are formed and maintained solely through human activity and accompany its settlements and places of activity. These groups appear where people have destroyed natural vegetation as a result of excavation, garbage disposal, intensive mechanical use, and agricultural activities in the fields. Synanthropic vegetation, thus, unites ruderal groups that act in landfills, roadside habitats, abandoned gardens, dumps, ie areas with a significantly changed habitat, and segetal groups which are related to agricultural areas. Synanthropic plants, falling into anthropogenically altered areas, at least in the beginning, do not meet resistance from plants of natural groups. The newly formed synanthropic communities, thus, are characterized by a short lifespan, which is the result of low competitiveness of invasive plants, which are part of them in comparison with the species of natural flora. Wild aboriginal species in the event of cessation of anthropogenic pressure displace synanthropic invasive species from ecosystems, natural vegetation is restored. Therefore, synanthropic vegetation require constant human influence
