THE CURRENT STATE OF THE FLORA OF THE STYR RIVER

Keywords: hydrophilic flora, species composition, acuatic, coastal acuatic vegetation.

Abstract

The geobotanical studies of aquatic and coastal aquatic vegetation on separate plots of the Styr river have been carried out for the first time. It was established that the species composition of hydrophilic flora is different in different parts of the river, but there are separate species that are characteristic only for a certain study area. According to the results of field studies, among the allocated taxa, 125 species of higher vascular plants from 75 genera and 38 families have been described. In the species composition, the most common 7 families are Poaceae (11 species), Potamogetonaceae (10 species), Asteraceae (9 species), Cyperaceae (8 species), Polygonaceae (8 species), Ranunculaceae (6 species), Saliсaceace (6 species). The indicated species of these families is 46,4 %. Among the identified genera, the dominant are Potamogeton (9 species), Salix (6 species), Juncus, Rumex and Carex (5 species). 6,4 % (8 species) – adventitious plants: Acorus calamus, Bidens frondosa, Echinocystis lobata, Elodea canadensis, Juncus tenuis, Salix fragilis, Xanthium albinum, Zizania latifolia, the rest represent aboriginal flora of Rivnenska oblast. It is established that in the ecosystem of the river a tendency towards the strengthening of transformation processes is observed. The hydrophilic flora was found to be poorer in the four sections of the lower stream. However, a particularly rich variety of species composition of the lower flow is allocated area between urban areas of Zarichne town settlement and Ivanchytsi village. As a result of cenopopulation studies of individual river sections, data were obtained that determine the state of populations of 6 rare species: Pulicaria vulgaris, Hippuris vulgaris, Batrachium rionii, Nymphaea candida (old man); Batrachium circinatum (Verben village); Potamogeton gramineus (Ivanchytsi village). For the first time in Rivnenska oblast there was found a highly destructive species of Batrachium rionii, which is included in the Red List of aquatic macrophytes of Ukraine. The most diverse area is defined, where the river forms the dead arm. A comparative analysis of various sections of the river gives an opportunity to evaluate the hydrophilic flora, to develop optimal ways of protecting rare and typical plants and their groups.
