AQUATIC, COASTAL AND FLOODPLAIN HABITATS OF THE RLP «YALIVSHCHYNA», THEIR SPECIES DIVERSITY AND ECOLOGICAL AND CENOTIC FEATURES

Abstract

The article is devoted to the study of aquatic, coastal, and floodplain habitats within the territory of the RLP “Yalivshchyna”. It analyzes the species diversity of these habitats and provides data on the classification of biotopes in the RLP “Yalivshchyna”. A preliminary classification scheme, based on the results of original research and some bibliographic data, is presented.
The analysis has revealed a significant diversity of aquatic ecosystems in the RLP “Yalivshchyna”, indicating the ecological stability and azonality of these systems within the park.
The aquatic, coastal, and floodplain habitats within the study area are characterized by seven main categories (types), which exhibit significant floristic diversity, including 130 species of vascular plants belonging to 78 genera and 41 families.
A notable feature of the studied habitats is the presence of a wide-ranging flora of most species due to their influence on water and floodplain systems. This results in the predominance of species characteristic of the Holarctic and Euro-Asian regions.
From an ecological perspective, the biotopes of the Stryzhen River within the territory of the RLP “Yalivshchyna” are significantly represented by vascular plant species from limnophytic groups, and marsh and hygrophilic florogenetic complexes. This diversity is influenced by the overregulation of the Stryzhen riverbed, slow flow, and the formation of bottom sediments of varying thicknesses.
The aquatic, coastal, and floodplain vegetation of the Stryzhen River is characterized by the presence of monodominant communities typical for this region, which exhibit limited species diversity, similar composition and structure of coenoses, and the influence of adventive species.
An inventory of habitats in the channel and floodplain parts of the Stryzhen River was carried out, allowing for an assessment of the natural environment in accordance with modern approaches. The data obtained on these habitats allows for the determination of their hierarchical structure and identification of the stability level of each habitat. This, in turn, will facilitate the development of appropriate conservation strategies for these habitats in the future and can be used to maintain and preserve aquatic ecosystems, ensure the balanced use of natural resources, and support the sustainable development of the RLP “Yalivshchyna”.
