Invasive species of the flora of transformed sections of railway tracks in the bottom of the Dnister–Tiligul river

In order to study invasive species as dangerous elements of foreign flora, modern monitoring studies are needed under the conditions various ecotopes a wide range their transformation. According «Strategy biosecurity and biological protection», alien threat biodiversity at its levels. Taking into account that railway tracks one main ways penetration initial establishment synanthropic in new territories, 2018–2021, flora areas Dniester floodplain was studied. 34 from 14 families were noted, they included Asteraceae (26.47% species), Brassicaceae Poaceae (17.65% each), Amaranthaceae (8.82%) others. The majority (55.88%) grows both on track sections (in addition) next ruderalized overburden. Another 11 (32.35%) can be found tracks, overburden roadsides nearby highway. Only two (5.88%) cultivated. Two more such Amaranthus powellii S.Watson, Oxybaphus nyctagineus (Michx.) Sweet noted only infrastructure. life form, nine (26.47%) hemicryptophytes. 23 ones therophytes (67.65%). fanerophytes (5.88%). chronotype, 41.18% aschaeophytes. Kenophytes make 58.82%. Among archaeophytes, most plant have frequency occurrence — «scattered» «abundant» (35.71% each). kenophyres, there whose plants (40.00%). general, species, by occurrence, belong (38.25%) (23.53%) categories. Also «single» (17.65%), «usually» (11.77%), «single locality» (8.82%). Most (70.60%) represented ranges: cosmopolitan (and hemi-cosmopolitan) 44.12%, Eurasian form 14.71%, Euro-American 11.77%. Eight particularly for environment, transformers local growth. also adjacent areas. Therophytes, kenophytes with prevail. They found, mostly «abundant». because transform ground place (Ambrosia artemisiifolia, Centaurea diffusa, Conyza canadensis, Grindelia squarrosa, Iva xanthiifolia, Elaeagnus angustifolia, Anisantha tectorum, Setaria glauca).
