Rare And Protected Species In Urban Flora Of Genichesk


S. Yu. Maltseva

Urbanization is one of the most characteristic features of scientific and technological progress, which is associated with the rapid growth of cities and the urban population. It leads to irreversible processes of transformation of the natural environment. It anthropogenic transformation in connection with the development of the city and the subsequent rapid urbanization deals a devastating blow to the remnants of natural fractions urbanflora, which is preserved in the vicinity of Genichesk and would threaten the survival of a number of rare species of plants that grow here only in small areas with a small number of individuals. The article studies the protected and rare species of plants growing in the urban environment Genichesk. The study was conducted by routing way, with the implementation of standard procedures for drying, installation and post-processing of herbarium specimens. The research resulted in found new habitats of species listed in the Red Book, such as Astragalus borysthenicus Klokov, Crambe maritima L., Tulipa gesneriana L., Astrodaucus littoralis (M. Bieb.) Drude, Stipa ucrainica P. Smirn., Tamarix gracillis Willd. Also in the article provides a brief description of 11 species of vascular plants and their sozological value. Saving the plants, which listed in the Red Book of Ukraine, in the city Genichesk, is a difficult task. The main limiting factors are destruction of habitat, degradation of soil cover. As a result of anthropogenic activities, cultivation, creation of pastures and destruction of natural habitats are declining habitat and abundance of rare and endemic species. Collect flowers for bouquets also reduces the number of rare species. Every year in the spring on the outskirts of the city lit dry grass, which adversely affects the early-flowering plants, including rare, such as Tulipa gesneriana L., Adonis vernalis L., Convallia majalis L. Despite this, a significant number of these plants not only grows urboecotope but also successfully propagates in these conditions. Results of the study show that in the city of Genichesk currently stored favourable living conditions for some protected species, including seven species of Red Book and four species are protected at the level of regional lists. But due to human activity remains a risk of extinction of rare species of Red Book and that requires further monitoring and control of the state of their abundance and distribution in the city, as well as measures to protect their habitats.
