Forest Shelter Belts

Forest shelter belts are one of the effective approaches in the fight against wind erosion, improving the microclimate of fields, protecting roads and reservoirs. The problem of assessing forest plantations and prospects for their creation is relevant for many countries of the world, due to the problem of desertification, water and wind erosion, as well as the global food crisis. The carried out analysis of scientific literature has shown that the existing assessments of forest shelter belts with insufficient degree are being taken into account the modern methods of remote sensing.Therefore, the problem of assessing forest shelterbelts from satellite imagery is relevant.The main part and research results. During the summer period of 2019, in the territory of the protective forest plantations of Fergana Valley of the Republic of Uzbekistan there were laid 170 testing plots. Then 20 test sites, which were used as reference for thematic mapping, there were laid with the collection of additional information: location coordinates and bookmark location.The purpose of the study is to assess the area of forest shelter belts zones of the Republic of Uzbekistan using remote sensing.The object of the study is forest shelter belts of Fergana Valley of the Republic of Uzbekistan.

The paper focuses on the insect community as a "link" between ecosystem producers, secondary consumers and decomposers and the mobile and informative indicator of structure, biological stability and productivity. Consortium and other subsystems of agricultural ecosystems are mainly destroyed annually as a result of technological measures - chemical, mechanical, biological. External ecological factors, including the structure of the agrolandscape, in particular field protective forest shelter belts and ecotones between them, also have a certain influence. The research was conducted in organic agrolandscape (Kyiv region, Ukraine), comparing it with the conventional one. Insects were collected in winter wheat fields, ecotones and adjacent forest shelterbelts. The number of orders, families and individuals is greater under organic farming. The highest number of families and individuals was recorded in the forest shelterbelts adjacent to the organic landscape (26.3 and 111.7, respectively). The number of individuals in organic winter wheat fields was twice as large as in conventional fields and amounted to 85.3 individuals on average; the number of families was by 1.8 times larger. Biodiversity indices (Shannon, Menhinick, Margalef, Berger-Parker, and Pielou) confirm the greater diversity of insects in the organic fields of winter wheat. The Sørensen similarity coefficient was higher in the organic fields and forest shelterbelts near the conventional fields (Cs=0.7), which is explained by the largest number of phytophages in these ecosystems. The share of predators and parasites that control pests in the agricultural system was highest in organic ecotones and forest shelterbelts - 26.21% and 33.12% (against 10.24 and 18.16% in conventional, respectively).

Today forestry in Russia is going through one of the most difficult periods in its history, which has resulted in decades of extensive wasteful land use. So, change of climate can bring desertification of some territories and various forms of degradation (desertification) cover about 60 percent of the land in the Rostov region, and the rest is potentially dangerous in this regard. The reasons are anthropogenic impact, drought, erosion, deflation. Despite the fact that in recent years Russia has been developing forestry legislation and has taken a course towards the development of sustainable growth and "green" one, the regions are taking measures aimed at protecting lands from degradation and preserving soil fertility, soil-destructive processes and desertification are increasing many times over. An inventory of forest resources in Russia was carried out in 2019 and it showed that the forest cover in Russia tends to decrease, and on the territory of the Rostov region, forest inventory was carried out in 2006, only 40% of all forests were taken into account - about 240 thousand hectares of protective forest plantations, from of them 125.8 thousand hectares are shelter belts. It’s imperative to enact urgent measures for reforestation and landscaping of territories and annually reconstruct forest belts and create new ones to improve environmental conditions in regions with low forest cover, otherwise in 10-15 years their mass natural death may occur.

Coccinellidae perform the function of biological control of pests in nature, they eat aphids and other insects, which is important in organic agriculture. The aim of the work was to establish the distribution and species composition of the family Coccinellidae in the organic agro-landscape. The research was conducted at the Skvyra research station of organic production (Kyiv region, Ukraine). Insects were collected by entomological mowing with a net in four stages of plant development. The organic agro-landscape included crops of buckwheat, oats, soybeans and winter wheat. Data from neighbor conventional soybean and winter wheat ecosystems were used for comparison. The agroecosystems of these crops, which included felds, ecotones ”feld – feld protective forest shelter belt”, feld protective forest shelter belts, were studied. The study identifed 10 species of the family Coccinellidae, the number of species ranged from 1 to 89/100 waves, the largest in the ecosystem of organic winter wheat. H. axiridis belonged to the recedents and was found in fve agroecosystems in the amount of 1-7 individuals / 100 waves. The most common species were C. septempunctata, T. sedecimpunctata and larvae of Coccinellidae, which were eudominant in the organic agro-landscape. Species Vibidia sp. was found only in organic agroecosystems of buckwheat and oats. The variety of ladybugs in organic winter wheat was higher than in conventional. Organic soybeans, in contrast, had less variety of Coccinellidae than conventional soybeans, as confrmed by cluster analysis. Species richness in crop ecosystems ranged from 3 to 8 in different study periods. High correlations of insect numbers were found between felds, ecotones and forest shelter belts, as well as between neighbor ecotones and neighbor forest belts, which indicates the migration of insects between these areas. Thus, the diversity and prevalence of Coccinellidae in the organic agro-landscape, compared to the traditional one, has been established. Key words: ladybugs, organic farming, agrolandscape, agroecosystem, crops, species.

Abstract The aim of this article is to assess the structure of biodiversity of field protective forest shelter belts to determine the directions of increasing their reclamation and conservation potential in the organic agricultural landscape. Methods of comparative ecology (synecological approach, assessment of α-diversity), forestry, geobotany, ornithology and statistical analysis are used. Changes in species diversity of plants and birds in forest shelter belts around organic fields are characterized. It is established that plantations with developed undergrowth and under-storey are transformed due to the loss of up to 43.5% of trees, liquefaction of the edificatory tier. Transformer species with a wide phytocenotic range predominate in the tree stands. The grass tier is dominated by ruderants (36.5%) and adventive species (24.5%). The share (60%) of species with a mixed life strategy indicates changes in moisture conditions and soil trophism. A 2.4% of shade-loving plants and the presence of 14.7% nitrophils indicate an imbalance in the structure of forest shelter belts. Depletion of species composition, ecological and trophic structure of bird groups testify to the decrease in the capacity of forest shelter belts and their statio diversity, reduction of protective, environment-creating functions and other ecosystem services. In the three-tiered dense forest shelter belts with developed undergrowth and understorey, 10–27 species of birds nest. In general, avifauna is represented by 2 ecological groups (93.1% dendrophiles, 6.9% sclerophiles), divided into 5 types of nesting strategy (with a predominance of hollow-nests 37.0–53.3%), and 5 types of feeding (with a predominance of entomophagous 70.4–90.0%). Twenty-nine species have been identified on nesting, 27 of which are subject to protection at the level of international agreements. There are no adventive species, the index of synanthropization of avifauna is high – 0.85–1.0. For organic technologies to increase the potential of biological protection of fields from entomological pests by attracting insectivorous birds is relevant.

Abstract The article presents the results of a cameral inventory of protective forest plantations of a linear type for any purpose for the steppe agricultural territories of the Crimean Peninsula in 2009 and 2019. As a result of the work, more than 20 thousand objects were identified, a geodatabase was compiled with a set of attributive information for each of the identified objects, indicating the length and quality characteristics of each object. An overview of the data obtained is presented for each of the diagrams, as well as a comparative analysis of the quantitative and qualitative characteristics of the identified objects for 2009 and 2019. It was revealed that from 2009 to 2019, 386 objects of the linear type corresponding to the parameters of protective forest plantations in agricultural areas, with a total length of 3.9 thousand were completely destroyed. That is, well-read forest stripes are present in the images for 2009, in the images of 2019 they are already missing.

The results of the study of protective forest plantations state in the Eastern Kama region of the Republic of Tatarstan are presented. The assessment of the study area landscape, the soil conditions for the formation of protective forests is given. Under the canopy of forest phytocoenoses, brown-brown forest, gray forest soils and rendzins are identified. Pine, spruce, birch, and poplar protective plantations, pure and mixed in composition, were studied. On the trial plots the taxation indicators of stands are determined. The peculiarities of the distribution of trees along the thickness steps and categories of the state are revealed. In pine biogeocenoses there are obviously more trees without signs of weakening: the content of healthy trees is 70.5-87.4%. Less stable are pine plantations created on stony soils of a steep slope. A higher proportion of healthy trees are allocated pine phytocenoses formed on loamy brown soils. Protective plantations of Almetyevsky municipal district, created from European spruce on soils with a developed profile, are distinguished by a high proportion of trees without signs of weakening. In the composition of deciduous plantations, a high percentage of trees without signs of weakening are inherent in the mulberry, which grows on brown-brown forest heavy loamy soil. There are no strongly weakened and drying trees. Birch grouse, formed on rendzine leached heavy loam on stony calcareous rocks, is less stable: the proportion of weakened trees increases to 20.1%.

The paper presents the results of studies of grain crops row sowing method agrotechnical indicators after the modernization of the working bodies of the SZS-2.1 seeder-cultivator. The SZS-2,1 stubble cultivator seeder has found wide application in the arid regions of the Republic of Buryatia, whose soils are prone to wind erosion. This seeder provides a combination of pre-sowing cultivation, sowing grain crops, applying mineral fertilizers to the sown rows and rolling them on stubble backgrounds, that is, in fields that have been processed since autumn with flat-cutting tools or have not been cultivated at all. Sowing with these seeders with 23 cm row spacing in a row method is the main method of sowing spring wheat in the soil conservation agriculture system. Routine sowing on soils of light texture, subject to wind erosion, causes thickening of plants in a row, which leads to irrational use of the feeding area by plants, increased weediness of crops between rows and, ultimately, to a decrease in yield. A distributor for the coulter has been developed, where the seeds are fed to the distributor. Then, reflecting from the distributor, the seeds are evenly dispersed in the opener under the plow space. Also, instead of serial wedge-shaped packer rollers, ring-spur rollers of the 3KSH-6 type are installed on the seeder. In addition, continuous rolling provides the necessary contact of seeds with the soil, preserves soil moisture and helps to attract it from the lower layers. Thus, the modernization of the SZS-2.1 seeder made it possible to substantiate subsurface-spread strip sowing with continuous rolling, which ultimately led to an increase in grain yield by 10-15%.

Various large-scale risk maps show that the eastern part of Austria, in particular the Pannonian Basin, is one of the regions in Europe most vulnerable to wind erosion. However, comprehensive assessments of the severity and the extent of wind erosion risk are still lacking for this region. This study aimed to prove the results of large-scale maps by developing high-resolution maps of wind erosion risk for the target area. For this, we applied a qualitative soil erosion assessment (DIN 19706) with lower data requirements and a more data-demanding revised wind erosion equation (RWEQ) within a GIS application to evaluate the process of assessing wind erosion risk. Both models defined similar risk areas, although the assignment of severity classes differed. Most agricultural fields in the study area were classified as not at risk to wind erosion (DIN 19706), whereas the mean annual soil loss rate modeled by RWEQ was 3.7 t ha−1 yr−1. August was the month with the highest modeled soil loss (average of 0.49 t ha−1 month−1), due to a low percentage of vegetation cover and a relatively high weather factor combining wind speed and soil moisture effects. Based on the results, DIN 19706 is suitable for a general classification of wind erosion-prone areas, while RWEQ can derive additional information such as seasonal distribution and soil loss rates besides the spatial extents of wind erosion.
