Opis:
Forests perform essential ecological functions - water protection, sanitation, health, recreation, and aesthetics. The research aimed to substantiate the ecological and economic importance of forest resources in the Kyiv region and analyse their rational use and protection. The article shows that the Kyiv region belongs to the regions with an average level of forest cover – 592.8 thousand hectares or 22.2%. The level of forest cover is uneven in the area of the Kyiv Forest zone. It is 44%, and in the area of the Forest-Steppe, it is much lower and decreases from north to south. The use of forest resources in the Kyiv region in 2019 amounted to harvesting liquid wood of 999.5 thousand m2, and deforestation was carried out on 75.5 thousand hectares. The region’s volume of forestry works and services amounted to 8,9 million dollars, and the wood stock makes 90805,9 thousand m2. Emphasis is placed on the importance of protecting the Red Book species of plants and fungi that grow in the forests of the Kyiv region. Examples of harmful economic activity in the areas belonging to the nature reserve fund and large-scale fires in April 2020, which covered more than 3.5 thousand hectares of forests in the region and caused damage to forest fauna and flora. The studied region’s positive environmental and economic factors have been admitted by planting trees on an area of 2151 hectares and sowing seeds of forest species on an area of 67 hectares in 2020.

Opis:
Chamaecytisus albus (Hacq.) Rothm. is an extremely rare species, which is inserted in many European red lists and red books. Its continuous range covers the south-eastern part of Europe. That species grows in intensely insolated and calcareous habitats of xerothermic grasslands. Only one station of White Broom had been known in the valley of the Bug river, near Hrubieszów, but in 2007 a new one was discovered near Jędrzejów. That station is located the farthest in the north and the west in Europe and it is completely detached from the continuous range.

Opis:
Semenov’s Fir (Abies semenovii B. Fedtsch.) is an extremely rare species in the wild and is included in the International Red List of Conifers and into the Red Data Books of the former USSR and Kyrgyz Republic. Our investigation confirms that this is an independent species, related but not identical to Abies sibirica Ledeb. It has been cultivated at Peter the Great Botanic Garden of the Komarov Botanical Institute of the Russian Academy of Science(s), St.Petersburg, since 1949. Apparently, it was here that Semenov’s Fir was first introduced into cultivation in European gardens. It has produced seeds since 2000, when it was less than 43 years old. It is a hardy and ornamental tree that deserves wider distribution in cultivation in the gardens and parks of North-West Russia. It is proposed that Semenov’s Fir should be given independent taxonomic status as a separate species, Abies semenovii B. Fedtsch.

Opis:
Aconitum bucovinense, a high-mountain species endemic to the Eastern and Southern Carpathians, including the Apuseni Mountains, is legally protected and classified in the Polish Red Data Book of Plants. It attains its NW geographical range in two peripheral populations in the Western Bieszczady Mountains (Polish Eastern Carpathians), isolated by a distance of 13.1 km. PCR-ISSR analysis has been used to elucidate the within- and among-populational levels of species genetic diversity. A UPGMA and block clustering showed discreteness of the populations and subpopulations based on ISSR banding pattern. Analysis of Molecular Variance (AMOVA) revealed significant divergence (P = 0.024) of the two marginal populations and highly significant (P < 0.001) differentiation of subpopulations within populations. The theta index calculated for the two marginal populations and the core population in the Carpathians was 0.131 ±0.030 S.D. Most of the population-genetic diversity indices of the marginal populations were not different from those in the core area but the Shannon’s and rarity indices were lower in the marginal populations. It seems that founder effect and subsequent genetic bottleneck resulted in a fine-scale population genetic structure. The marginal populations under study need a relevant recovery program to maintain their genetic diversity.
