The floristic study in the central square of the town. Bălți (near the bell tower) indicates that the flora of the urban ecosystem was formed as a result of the preservation of spontaneous autochthonous species, which adapted to the conditions of urbanization, as well as non-native species, which penetrated the territory of the country in different ways. The floristic spectrum of the resort is represented by 41 species, grouped into 37 genera from 21 families of magnoliophytes. Within the resort, the presence of two invasive species is attested: Erigeron annuus (L.) Pers and Humulus lupulus L. Their capacity to adapt and multiply is quite high and as a result could contribute to the elimination of spontaneous flora species, which is represented by 18% of the total species. The large share of ruderal (56%) and segetal - ruderal (26%) groups is an index of the degree of anthropization of the ecosystem, which is reflected on the vegetation of the study area.
