Ecological impact of Robinia pseudoacacia L. on the state of forests of the “Drevlianskyi” Nature Reserve

<ns3:p>The ecological impact of artificial plantations and spontaneous habitats of Robinia pseudoacacia L. on the aboveground cover in the forest ecosystems of the Drevlyansky Nature Reserve (Narodychi, Zhytomyr region, Ukraine) was determined. The inclusion of R. pseudoacacia L. in the "Black List" of invasive species that are dangerous for the objects of the nature reserve fund of Ukraine with a high intensity of spread and aggressive transformational impact on the phytostroma and landscapes is substantiated. The changes in the grass cover in the habitats of the species were analysed, and the taxonomic phytodiversity was summarised (ROBINIETEA Jurko ex Hadac et Sofron 1980). It is proven that R. pseudoacacia L. plantations cause changes in the biodiversity of the territory, namely, reducing the projected cover of native herbaceous plants, having an allelopathic effect and a high capacity to compete with native species, thereby displacing them from the phytocoenosis. The difficulty of removing a species from the phytocoenosis and the risks of biodiversity depletion are particularly significant. The results obtained are important for the development of biotechnical measures to preserve natural forest ecosystems and control the spread of invasive species and plants that transform the environment.</ns3:p>
