Comparison of partial floras of flower beds in the cities of the southern part of the Udmurt Republic

Investigating floras of anthropogenically disturbed areas is quite important for identifying the dynamics of urban floras, that can be determined when analyzing certain types of partial floras. The aim of our work was to conduct research and compare the partial flora of the flower beds in the cities of the southern part of Udmurtia, as the most dynamic. The research was conducted in three cities of the UR (Votkinsk, Moz-hga and Kambarka). Material collection was carried out within the administrative boundaries of these cities by method of partial floras and route method. As a result of the conducted research it was found that the combined partial flora of flower beds in studied cities includes 278 vascular plants species from 55 families, most of which are adventive ones (152 species).The largest amount of plant species growing in the flower beds in urban floras is registered in Votkinsk - 270, slightly smaller amount in Mozga - 237 and Kambarka - 225. 209 species are common for partial floras of flower beds of Votkinsk, Mozhga and Kambarka, specifically 116 aboriginal species and 93 adventive ones. Among the adventive species approximately 37% (34 species)are invasive plants. Floristic compositions have a higher degree of similarity in the pairs of Votkinsk-Mozhga and Mozhga-Kambarka.
