The Republic

The forest has always played a big part in Belarus. At present it covers about 40% of area of the country`s territory. Predominantly the forests are of natural origin. The main species are Pinus sylvestris L. (Scotch pine), Betula pendula Roth (European white birch) and Picea abies (L.) Karst. (Norway spruce). The other valuable species are Quercus robur L (English oak), Alnus glutinosa (L.) Gaertn. (European alder), Larix decidua Mill. (European larch), Abies alba Mill. (Silver fir). The history of the forest management in Belarus showed that over last 150 years the enormous damage to the qualitative and quantitative composition of forests had been made by wars and reconstruction of destroyed industry. The taken reforestation measures allowed to increase the forest area significantly, however, the work on improving of forests` quality requires further development. At present the artificial forest regeneration prevails in the republic. Over the past five years the volumes of established forest plantations range from 21 to 25 thousand hectares annually, the areas of assistance to the natural regeneration – from 4 to 6 thousand hectares annually. By now there are about 1,700 ha of the forest seed orchards, 2,795 plus trees and 1,125 ha of the plus stands in the republic. The cultivation of planting stock for needs of reforestation is carried out on 73 forest tree nurseries with a total area of 1,440 ha. Annually over the last five years there were grown from 270 to 317 million seedlings and transplants, among them 30-35 million seedlings were grown in greenhouses and about 6 million were container seedlings. In order to improve the gene resource and thereby to increase the productivity and quality of future forests, the tendency of forest plantations` prevalence in the reforestation process of Belarus should remain, but in this case the volumes of partial forest plantations should be increased.

Forest Tree Species

Patterns and driving forces for seed production in forest tree species Why is the annual fruit production in forest tree species not constant, and which factors cause massive fruit production (seed mast year)? These and other related questions were already posed more than 100 years ago when tree breeding was economically beneficial. The questions have not been fully answered, yet. Rather, the same questions are studied again today as the climate is changing and the uncertainty about the continuation of forests at their current locations is growing. A 25 year long observation series on the variation of fruit production in Switzerland revealed a mean frequency of three years for mast seeding (full and medium mast) at low elevation on the Central Plateau in European beech (Fagus sylvatica), oak (Quercus petraea, Q. robur) and silver fir (Abies alba). In contrast, mast seed years of Norway spruce (Picea abies) occurred, on average, every sixth year. In 1992 and 2011, all four species synchronously showed mast seeding. The results are discussed in the light of different theories and new research findings. From the state of the current know ledge, we derive the need for long-term and fine-scale baseline data and present the new reporting and information webpage «mast web.ch». Here, volunteers can report observations on the fruit production of main tree species following a few simple criteria (citizen science approach). With this data, distribution maps on mass fructification levels will be made available and will serve for spatio-temporal fine-scale studies on mast seeding phenomena.

The aim of the study was to determine the water storage capacity and absorbability of deadwood of different tree species with varying degrees of decomposition. Coniferous (Silver fir—Abies alba Mill.) and deciduous (Common hornbeam—Carpinus betulus L., Common ash—Fraxinus excelsior L., Common alder—Alnus glutinosa Gaertn., and Common aspen—Populus tremula L.) species were selected for the research. The study focuses on the wood of dead trees at an advanced stage of decomposition. Deadwood samples were collected at the Czarna Rózga Nature Reserve in central Poland. Changes over time of the water absorbability and water storage capacity of deadwood were determined under laboratory conditions. The research confirmed the significance of the wood species and the degree of wood decomposition in shaping the water storage capacity and absorbability of deadwood in forest ecosystems. Fir wood was characterized by having the highest water storage capacity and water absorbability. Among deciduous species under analysis, aspen wood was characterized by having the highest water storage capacity and absorbability. Our research has confirmed that deadwood may be a significant reservoir of water in forests.

Simulation Results

AbstractThe FORKOME model used in the article contains elements of forest and ecological approaches and was specially developed for the conditions of the Gorgans. The modeling was performed based on the single simulation results and statistically averaged forecast of 200 simulations (“Monte Carlo”) in order to show the tendency of changes and their correspondence with single simulations. The forecast of the forest dynamics was conducted at the 100th anniversary period with “control” and “warm-dry” scenarios. It has been revealed that the rapid decrease in biomass in the first decade was caused by Norway spruce decline. It was revealed that in the control scenario, the most active biomass growth during the 100th year forecast was shown by Silver fir (Abies alba Mill.) and beech (Fagus sylvatica L.). The fir reacted relatively sensitively to the warming and decrease in rainfall. The relationships between tree species and the influence of biomass of Norway spruce tree on the biomass of the whole forest tree stand were analyzed.

AbstractForest tree seedling production technologies impact reforestation success determined with survival and quality of seedlings. Five Abies alba seedling production technologies were tested: (1) bare-root seedling, three years in the open (3/0); (2) bare-root seedling, two years under a shading net (40% of full light), a year in the open (2/g); (3) ball root seedling, two years under a shading net (40%), a year in the open (2/K); (4) bare-root seedling grown in an opening in a Norway spruce stand (3/Pic); (5) bare-root seedling, three years under Scots pine canopy (3/Pin). Silver fir seedlings acclimatized their growth rates to the common growing environment in relation to the seedling production technology used in the nurseries. The height and diameter at root collar were positively correlated with survival. The 3/Pic seedlings manifested the lowest survival and were lower than other seedlings in terms of height and photochemical efficiency. The needle photochemistry of seedlings growing two years in plantation was determined by their earlier acclimation to the nursery light conditions. The production technology determined the ability of A. alba seedlings to acclimatize to the natural environment. Ball root seedlings grown two years in shade and a year in the open (2/K) acclimatized better to the full light environment compared with bare-root seedlings produced in canopy shade, and they are likely more suitable to be planted after clearcutting.

The history of local government in South Africa dates back to a time during the formation of the Union of South Africa in 1910. With regard to the status of local government, the Union of South Africa Act placed local government under the jurisdiction of the provinces. The status of local government was not changed by the formation of the Republic of South Africa in 1961 because local government was placed under the further jurisdiction of the provinces. Local government was enshrined in the Constitution of the Republic of South Africa arguably for the first time in 1993. Under the interim Constitution local government was rendered autonomous and empowered to regulate its affairs. Local government was further enshrined in the final Constitution of 1996, which commenced on 4 February 1997. The Constitution refers to local government together with the national and provincial governments as spheres of government which are distinctive, interdependent and interrelated. This article discusses the autonomy of local government under the 1996 Constitution. This it does by analysing case law on the evolution of the status of local government. The discussion on the powers and functions of local government explains the scheme by which government powers are allocated, where the 1996 Constitution distributes powers to the different spheres of government. Finally, a conclusion is drawn on the legal status of local government within the new constitutional dispensation.

The paper provides a review on the joint Russian-Belarusian tutorial “History of the Great Patriotic War. Essays on the Shared History” published for the 75th anniversary of the victory in the Great Patriotic War. The tutorial was prepared within the project “Belarus and Russia. Essays on the Shared History”, implemented since 2018 and aimed at publishing a series of tutorials, which authors are major Russian and Belarusian historians, archivists, teachers, and other specialists in human sciences. From the author’s point of view, the joint work of specialists from the Russian Federation and the Republic of Belarus in such a format not only contributes to the deepening of humanitarian integration within the Union state, but also to the formation of a common educational system on the scale of the Commonwealth of Independent States or the Eurasian integration project (Eurasian Economic Union – EEU). The author emphasises the high research and educational significance of the publication reviewed when noting that the teaching of history in general and the history of the Second World War and the Great Patriotic War in particular in post-Soviet schools and institutes of higher education is complicated by many different issues and challenges (including external ones, which can be regarded as information aggression by various extra-regional actors).

By analyzing one of the most eventful periods of the modern history of Poland, the early 80s of the XX century, the author examines the dynamics of social and political conflict on the eve of the introduction of martial law, which determines the location of the leading political forces in these events in Poland, that were grouped around the Polish United Labor Party and the Independent trade union «Solidarity», their governing structures and grassroots organizations, highlighting the development of socio-political situation in the country before entering the martial law on the 13th of December and analyzing the relation of the leading countries to the events, especially the Soviet Union. Also, the author distinguishes causes that prevent to reach the compromise in the process of realization different programs, that were offered to public and designed by PUWP and «Solidarity» and were “aimed” to help Polish society to exit an unprecedented conflict. This article provides a comparative analysis of the different analytical meaningful reasons, offered by historians, political scientists, lawyers, and led to the imposition of martial law in the Republic of Poland. The author also analyses the legality of such actions by the state and some conclusions that were reached by scientists, investigating the internal dynamics of the conflict and the process of implementation of tasks, that Polish United Workers’ Party (which ruled at that time) tried to solve with martial law and «Solidarity» was used as self-determination in Polish society.
