Self-renewal of tree plants in the conditions of the ecotope of the forest park of the Friendship of the city of Dnipro
Every year the role of parks in large industrial cities becomes more relevant. The consequences of anthropogenic impact are extremely powerful and diverse. Moreover, nature is trying to restore a clean ecological space on its own, so parks in cities are the driving force in the struggle for survival. The green lungs of the city create a qualitatively better climate, give the opportunity to rest, recuperate, give a feeling of peace, aesthetic pleasure and not only from the local flora, but also from unusual plants that inspire and cheer up, which is important for today's rapid pace of life. Therefore, the issue of aboriginal and introduced flora of parks will remain relevant. The species composition of seed self-regeneration of woody plants in trial areas 1, 2, 3 of the Druzhby Forest Park of Dnipro was analyzed in order to determine the ratio of introduced and autochthonous species and whether introduced species pose a threat to aboriginal flora. It has been investigated whether the distribution of introduced species contributes to the process of biotic homogenization using the Pearson correlation coefficient, the Jacquard index between indigenous species and introduced species. As a result of the research it was established that in the Druzhby Forest Park artificial stands are capable of forming a sufficient number of viable undergrowth of autochthonous and introduced species, of which aboriginal species dominate mostly. The ratio of indigenous species to introduced in Trial Areas 2, 3 is 66.5–65.5% and 33.5–34.5%, respectively. There is no competition between autochthonous and introduced species in these trial areas. Each tree species has adapted well to the conditions of the ecotope and to the conditions of its place of growth. Bioecological features of wood species in the plantations are not an obstacle to the development of the internal space of the ecotope. However, in Trial Area 1, competition was found between indigenous and introduced species, where introduced species make up 80.3% of the total number of restored woody plants. Therefore, longer-term monitoring and measures to curb the spread of introduced species is needed.
