As a consequence of the intensive economic use of oak forests in the region, the share of stands of natural origin is significantly reduced, which requires an in-depth study of their condition, productivity, and natural restoration processes. The purpose of this study is to investigate the state, structure, and reforestation processes of oak forests for their further natural reproduction. Generally accepted methods in forestry and comparative ecology were used to compare the dynamics and condition of the studied stands with the reference ones. The paper presents the findings of the study of the productivity and state of natural forests within the state enterprise “Khmilnytske lisove hospodarstvo”. It was found out that natural oak stands are represented by 7 forest types, mainly in fresh hornbeam oak forest (area – 471 hectares). According to the results obtained, it was found that natural oak stands of vegetative origin predominate within the studied enterprise (528.6 ha). They are mainly represented by forests of the 11th age class (188.0 ha). High-bonitat oak forests of the 1st quality class predominate. Mature and over-mature stands have slightly lower productivity (2nd quality class, stand density of 0.6-0.7). The largest total reserve is characterised by stands of the 11th age class. The maximum average reserves are typical for stands of the 9th age class (290 m3 /ha). The greatest share of oak in stand composition (9-10 units) was found in stands of 9-10 age classes. The study shows that the natural renewal of oak is concentrated mainly in fresh sudubrava (fresh hornbeam sudubrava) in plantings in the presence of Scots pine and common oak. The density of natural renewal is 1-3 thousand units/ha. The practical value of the study is conditioned by the possibility of introducing the basic principles of forestry aimed at growing stable high-yield stands of common oak through more complete utilisation of natural renewal

The paper presents the findings of a study of species diversity of forests in the Kharkivska Oblast. The study was conducted on the territory of ten forestry enterprises and the State Enterprise Kharkiv Forest Research Station and the Homilsha Woods National Nature Park on an area of 282.3 thousand ha (area is subordinated to the State Forest Resources Agency of Ukraine). The purpose of the study was to analyse the species diversity and typological structure of forests in the Kharkivska Oblast. The study of species diversity was carried out based on analysis of the subcompartment database of the VO Ukrderzhlisproekt. The plantations were classified by the trophotope on the territory of the research facility in accordance with the main methodological provisions of the Ukrainian forestry and forest typology. A diagrammatic map of forests and dominant species (common oak and Scots pine) was compiled using the MapInfo Professional 12.5 software package and a vector map of 12 forestries in the Kharkivska Oblast. It has been established that 56 species of trees grow in the Kharkivska Oblast. Among these tree species, the predominant ones are common oak (53.4%) and Scots pine (32.7%). The distribution of plantations by trophotope is characterised by certain features. For example, dubrava conditions prevail in the stands (65.6% of the total area covered by forest vegetation), subor forests are 3.5 times less represented, and sudubravas and pine forests are the least common. Among the forest types, the most common are fresh maple-linden dubravas (43.7%) and fresh oak-pine subors (18.9%). The practical significance of the study is that the analysis of species diversity and typological structure of forests must be taken into account during the planning, organisation, and conduct of forestry activities in the Kharkivska Oblast

The study of the forestry-taxation structure of plantations plays an important role during the conduct of economic activities in the territory of forest enterprises of Ukraine. So, timely taken forestry measures will allow to increase the productivity of forest plantations in the territory of forestry enterprises in the future. The database of the Ukrderzhlisproekt JSC as of 01.01.2012 was used for the analysis of the forestry-taxation structure of forests at the State Enterprise "Kremenets Forestry". The typological diversity of forests was characterized according to the developed classification of Alekseiev-Pogrebniak. The total area of the forestry land of the state enterprise “Kremenets Forestry” for the period from 01.01.2009 to 01.01.2012 has not changed and makes up 28,9 hectares, only the area of forest crops increased by 369 hectares and areas covered with forest vegetation increased by 184 ha, the total reserve increased by 246cubic meters and a natural renewal increased by 27 hectares. The structure of areas covered with forest operational forests are prevailing, the share of which is 51 %, forests of nature protection, scientific, historical and cultural purposes – 28 %, recreational-and-health-improving forests – 19 %, and protective ones – 2 % only. The typological diversity of forests in the territory of the experimental site is characterized by a significant number of forest types. The largest area is under the fresh hornbeam forest – 12374 hectares (of which 7378 hectares (60 %) under common oak and other species), and the least area is under the raw black-alder sudubrava – 333 hectares, while other types of forests occupy 408 hectares. The largest total reserve is the pine forest, which is 2785 thousand m3, the second by the number - common oak – 2319 thousand m3, the smallest reserve is forest beech (0,5 thousand m3) and other wood species (0,3 thousand m3). The average change in the reserve at the state enterprise "Kremenets Forestry"; pine forest and common oak have the largest change (49 and 37 thousand m3), and the smallest change in the reserve is in forest beech and other wood species and makes up only 0,26 thousand m3. The average age of wood species: common oak – 67 years (the largest one), common hornbeam – 66 years, pine and silver birch – 57 years, norway spruce has the smallest average age – 33 years. By improvement cutting, the formation of plantations of good natural composition and improvement of the sanitary condition of forests is carried out in an area of about 1,4 hectares in average over the last revision period

On behalf of the Federal Office for the Environment (FOEN), the Swiss College for Agriculture established the basis to foster oak species in Switzerland. For this, the growth areas of three oak species, common oak (Quercus robur), sessile oak (Q. petraea) and pubescent oak (Q. pubescens) were assessed throughout the entire country. The assessment was based on their physiological potential, their natural growth area and on the appearance of the middle spotted woodpecker. In addition, the older mixed oak stands were surveyed. These fundamental data were collected with a geographical information system and analyzed for each canton. Altogether, approximately one-fourth of the Swiss forest area is suitable for oak. The natural oak growth area covers however 38 500 ha only. About 19 000 ha of forest are populated by the middle spotted woodpecker and extended older mixed oak forests are found on approximately 24 500 ha. According to the applied evaluation matrix, the greatest potential for fostering oak species lies in eight cantons: Aargau, Zürich, Solothurn, Thurgau, Vaud, BaselLandschaft, Ticino and Schaffhausen.

Soil C Sequestration

AbstractSoil carbon (C) reservoirs held in forests play a significant role in the global C cycle. However, harvesting natural forests tend to lead to soil C loss, which can be countered by the establishment of plantations after clear cutting. Therefore, there is a need to determine how forest management can affect soil C sequestration. The management of stand density could provide an effective tool to control soil C sequestration, yet how stand density influences soil C remains an open question. To address this question, we investigated soil C storage in 8-year pure hybrid larch (Larix spp.) plantations with three densities (2000 trees ha−1, 3300 trees ha−1 and 4400 trees ha−1), established following the harvesting of secondary mixed natural forest. We found that soil C storage increased with higher tree density, which mainly correlated with increases of dissolved organic C as well as litter and root C input. In addition, soil respiration decreased with higher tree density during the most productive periods of warm and moist conditions. The reduced SOM decomposition suggested by lowered respiration was also corroborated with reduced levels of plant litter decomposition. The stimulated inputs and reduced exports of C from the forest floor resulted in a 40% higher soil C stock in high- compared to low-density forests within 8 years after plantation, providing effective advice for forest management to promote soil C sequestration in ecosystems.

Opium poppy cultivation in Thailand fell from 12,112 hectares in 1961 to 281 ha in 2015. One outlier exists: Chiang Mai province’s remote southwestern district, Omkoi. 90% of the district is a national forest reserve where human habitation is illegal. However, an ethnic Karen population has lived there since long before the law that outlawed them was created, unconnected to the state by road, with limited or no access to health, education and other services: they cultivate the majority of Thailand’s known opium poppy, because they have little other choice. They increasingly rely on cash-based markets, their lack of citizenship precludes them from land tenure which might incentivize them to grow alternate crops, and their statelessness precludes them from services and protections. Nor is the Thai state the singular Leviathan that states are often assumed to be; it is a collection of networks with divergent interests, of whom one of the most powerful, the Royal Forestry Department, has purposely made Omkoi’s population illegible to the state, and has consistently blocked the attempts of other state actors to complexify this state space beyond the simplicity of its forest. These factors make short-term, high-yield, high value, imperishable opium the most logical economic choice for poor Karen farmers residing in this “non-state” space.

Agriculture of the Northern regions specializes in animal husbandry, in this regard an urgent problem of crop production in the conditions of the Northern regions of the Russian Federation is the creation of precocious, high-yielding varieties of grain crops for fodder purposes. The article reflects the selection achievements in grain crops over the past seven years. The presented new varieties combine high yield, increased environmental plasticity, and have the ability to reduce their productivity to a lesser extent when cultivated in the harsh conditions of the Northern region. Breeding work conducted at the laboratory of crop production of the Primorskiy filial FGBUN FICKIA RAN - ArhNIISKH in 2005-2019, in breeding semipolar rotation in accordance with the "Guidelines on the selection of barley and oats" (2014), methodology of State Commission for testing of agricultural crops (1985). The digestibility of winter rye dry matter was determined by in vitro method on an artificial stomach. Statistical processing of experimental results was performed using the AGROS version 2.07 selection and genetic software package. Results of the study. As a result of selection work, precocious productive varieties of grain crops of the feed direction were bred and included in the state register. Bereginya — new-generation winter rye variety, universal use, with a low content of water-soluble pentosans in the grain. The variety has been included in the State register of selection achievements since 2013. Variety of spring barley Tausen — feed direction, resistant to environmental stress factors, high-yielding, resistant to lodging and pathogens (dusty smut, spotting). It has been included in the State register of selection achievements since 2014. Spring barley variety Kotlassky — feed direction precocious, productive, adaptive to adverse environmental factors, for obtaining concentrated feed for livestock and poultry. It has been included in the State register of breeding achievements since 2019. Arhan spring oat variety — environmentally plastic adapted to changes in soil and climate conditions, immune to dusty smut, combines a high yield of grain and green mass. Since 2020, it has been included in the State register of selection achievements.

The application of competition policy to nationalized industries (state enterprises) has been strengthened recently in the United Kingdom. Section 11(1) of the 1980 Competition Act broadened the Monopolies Commission oversight of state enterprises. In practice, the Commission will conduct an efficiency audit of each major nationalized industry every four years. The Commission will focus its review on the quality of services, manpower utilization and productivity, and pricing, distribution and purchasing methods of the state enterprise. These efficiency audits have been fairly well received. Their cost-effectiveness and the follow-through on the Commission's recommendations remain to be demonstrated.
