МОХОПОДІБНІ ТА СУДИННІ РОСЛИНИ НА ТЕРИТОРІЇ ЗАЛІЗНИЦІ МІСТА ЛЬВОВА

Abstract

The article presents a list of plants on railway tracks in the Lviv city, which includes 409 species (41 species of mosses and 368 species of vascular plants) which belong to 275 genera and 86 families of six divisions: Marchantiоphyta, Bryophyta, Equisetophyta, Polypodiophyta, Pinophyta, Magnoliophyta. The features of systematic and factional flora’s structures, character of the distribution of species of vascular plants and mosses in the different ecotypes of railway were analyzed. It is shown that bryophytes-apophytes prevail on the territory of the railway (92.7 %), including eventapophytes ( 52.6 %) and hemiapophytes (47.4 %). Among vascular plants apophytes also dominate (57.6 %), but adventitious species actively penetrate (37.2 %) (including archeophytes (42.3 %) and kenophytes (57.7 %). There is a small number of indigeneous species: mosses – 7.3 %, vascular plants – 5.2 %. Plants often choose the territory adjacent to the railroad bands (77.5 %) for their growth, they happen on embankments and ditches (52.5 %), and also on railway line (40.7 %). We found a number of plants that are dangerous to the natural ecosystem, including invasive species, quarantine and hazardous, and also those species that are especially spread intensely over the area recently.
