<p>Even though the actual levels of anthropogenic pollution around South Eastern Europe do not reach the ones experienced in numerous Central and Western locations such as the Po Valley, the Benelux regions, the English Channel, etc., both nitrogen and sulphur oxides remain a cause for concern for air quality issues in the area. S5P/TROPOMI offers a high enough spatial resolution of 3.5x7km<sup>2</sup> (x5.5km<sup>2</sup> since August 2019) coupled with a high signal-to-noise to allow the monitoring of air quality levels, as well as the calculation of emissions, around the overpass time of the satellite. In that respect, LOTOS-EUROS Chemical Transport Model (CTM) simulations for year 2018 will be used in conjunction to the S5P/TROPOMI NO<sub>2</sub> v01.03.02 and SO<sub>2</sub> v01.01.07 columns to update the current emission inventory used in CAMS, provided recently by TNO for year 2015.</p><p>The process is validated at every step; the CTM surface concentrations are being compared to the European Environmental Agency E1a & E2a in situ air quality station data while the satellite vertical columns are compared to MAX-DOAS ground-based measurements. The diurnal variability of the NO<sub>2</sub> depicted by the in situ and the CTM is examined, as a source of understanding the effect of the apriori emission fields, the OH radical chemistry, the planetary boundary layer definition, etc., within the model structure. The seasonal variability of the SO<sub>2</sub> columns observed by the satellite and ground-based instruments reveals the amount of insufficiently filtered power plants and smelting activities in the area, including transboundary transport around the Balkan Peninsula.</p><p>Area sources, such as cities and industrial regions, as well as shipping plumes around the Aegean Sea, the Bosporus Strait and the Eastern Mediterranean, will be characterized vis-à-vis their updated emissions and discussed.</p><p><em>Acknowledgements:</em></p><p>We acknowledge support of this work by the project “PANhellenic infrastructure for Atmospheric Composition and climatE change” (MIS 5021516) which is implemented under the Action “Reinforcement of the Research and Innovation Infrastructure”, funded by the Operational Programme "Competitiveness, Entrepreneurship and Innovation" (NSRF 2014-2020) and co-financed by Greece and the European Union (European Regional Development Fund).

Forest Genetic Resources

The aim of the article is to generalize the information presented in the FAO report ‘The State of World Forest Genetic Resources (FGR) and in the reports on the state of forest genetic resources in Ukraine and other countries. Results and Discussion. To draw up the World Report, the information was provided by 86 countries which occupy 76% of the earth's surface and involve 85% of the total forest area. The countries’ reports cover 8,000 species of trees, palm trees and bamboo, among which about 2,400 are economically important; at that, information at the genetic level is only available for 500 to 600 species. The vast majority of important for environmental protection species (84%) are indigenous, in contrast to those economically important, 85% of which are introduced species. About 50 indigenous and non-native species of forest trees are used in the forestry of Ukraine. 26 of them are given as high-priority ones. They are used to produce wood, pulp, fuel, non-timber products, as well as to create protective plantations. The total number of species and subspecies in the world that are preserved in situ is almost 1,000, with about 500 of them – in Asia and almost 200 in both Europe and Africa. In Ukraine, there are about 30 of such species. In cases where in situ conservation is problematic, alternative methods are used, namely ex situ. The total number of species that are conserved ex situ is 1,800; at that, 1,025 of them grow in Africa, 401 – in Europe, 389 – in Asia, 372 – in Latin America and the Caribbean, 265 – in North America, 102 – in the Middle East and 57 species – in Oceania. In Ukraine, they make a stock of the seeds of more than 130 tree and shrub species, including decorative ones. Man-made forests are created with more than 20 species of trees annually. Non-native species of woody plants in the forestry of Ukraine make 39%. Methodological approaches to the study of genetic variability involve analysis of biometric, morphological and biochemical characteristics, as well as DNA markers. They analyze genetic variation as in field studies in provenance trail and progeny tests, so in laboratory studies. Conclusions. The basic tasks for the forest genetic resources conservation is to develop and implement national in situ and ex situ conservation strategies for sustainable use of FGR, to strengthen the role which forests and protective stands play in the in situ FGR conservation, and to identify first-priority measures at the species level. FGR conservation strategies should contribute to both ecosystem restoration using appropriate genetic material and adaptation to climate change along with mitigating its impacts.

This paper presents the results of an analysis of the existing seed sources managed by SE ?Srbijasume?. A proposal has been given for new seed sources to be designated in forest areas. This paper highlights the significance of seed sources as a form of in situ conservation, as well as the necessity of establishing seed orchards as a form of ex situ conservation of forest genetic resources, which improves the mass production of reproductive material of forest trees characterized by good genetic quality.

Abstract Forest genetic resources (FGRs) are an important source of biodiversity conservation and forest restoration. Today, more than 600 genetic reserves (GRs) of more than 30 main forest tree species have been allocated in Ukraine. The main aim of the work is to reveal the features of the distribution, environmental condition and the trends of state of in situ gene sources of broadleaved tree species in the Right-Bank Forest-Steppe of Ukraine. Based on the research results, it has been established that the share of FGR in situ is only 0.3–0.5% of the total forest area of the region. The predominant species of forest stands of the region are English oak (Quercus robur L.) – 37.7%, European beach (Fagus sylvatica L.) – 26.8% and Common ash (Fraxinus excelsior L.) – 7.6%. The in situ locations of Black alder (Alnus incana L.), Sessile oak (Quercus petraea (Matt.) Liebl.), English oak and Common ash are characterized by the highest average annual temperature (8.1–8.2°С), the accumulated temperatures for the growing season (3111.9–3237.1°С). Stands with the European beech predominance are allocated in better moisture conditions by the precipitation-temperatures ratio (Selianinov Hydrothermal Index (HTI) – 1.769–1.802; climatic index by Vorobyov – 2.707–2.951). The in situ gene pool conservation units are defined by 12 soil types that are included in the 7 main groups according to the FAO international classification. The largest number of sites, 67 (56.8%), is concentrated on grey and dark-grey forest soils (Haplic Greyzems) (47%). According to the research results, GRs are not evenly distributed, they do not fully reflect the environmental diversity, and their area is negligible. We indicated the unsatisfactory condition of most genetic reserves. It was caused by reducing the share of main tree species, decrease in relative stocking density of stands and tree-breeding structure and deterioration of tree stands condition. This requires the development and implementation of an integration strategy based on the established concept of developing a national ecological network on both national and pan-European levels.
