На примере Кулундинского дендрария приведены материалы мониторинга интродукционных ресурсов деревьев и кустарников. Успех введения их в культуру защитного лесоразведения базируется на детальном изучении эколого-биологических особенностей, опыта интродукции в новых условиях. Из-за возросшей в последние годы антропогенной нагрузки используемый ассортимент древесных растений в защитных лесных насаждениях аридных территорий требует обновления. Постановка проблемы включает – выделение ценного генофонда для создания семенных баз и выращивания адаптированного посадочного материала. Показано, что в условиях Кулундинской степи интродуценты в защитном лесоразведении используются еще недостаточно широко, ассортимент древесных видов беден (Betula pendula Roth., Populus balsamifera L., Pinus sylvestris L., Larix sibirica Ledeb., Salix fragilis L.). Сопутствующие древесные растения представлены Acer negundo L., Malus pallasiana Juz., Ulmus pumila L. Другие древесные виды применяются в защитном лесоразведении в ограниченных масштабах. Цель исследований – оценка интродукционной устойчивости генофонда Кулундинского дендрария на основе мониторинга и комплексного изучения их биологических особенностей в условиях Кулундинской степи для защитного лесоразведения. Кулундинский дендрарий создан в 1977 году, он расположен на территории Западно-Сибирской агролесомелиоративной опытной станции (участок 49098 м2, кадастровый номер 22:23:010003:0014). Тип почв – каштановые, легкосуглинистые. Основные запасы гумуса сосредоточены в верхнем горизонте и с глубиной уменьшаются от 2,7 до 0,6%, Глубина залегания грунтовых вод 5-6 м. Выявлено, что видовой состав деревьев и кустарников Кулундинского дендрария включает 143 таксона из 52 родов и 25 семейств. К числу хозяйственно ценных родовых комплексов относятся представители семейства Rosaceae. Установлено, что представители семейства Rosaceae, как интродукционный ресурс для обогащения лесомелиоративных комплексов и формирования комфортных условий проживания населения, занимает одно из самых крупных по таксономическому составу древесных видов и важным по многофункциональному использованию. Рассмотрены методические подходы по проведению мониторинга интродукционных ресурсов, предложена методика расчета интродукционной устойчивости растений к новым условиям произрастания включающая группы признаков (зимостойкость, засухоустойчивость, побегообразовательная способность, прирост в высоту, генеративное развитие, возможный способ размножения в культуре) и приведено соотношение коллекционного фонда по показателям и размерностям шкал. Материалы по мониторингу интродукционных ресурсов Кулундинского дендрария ФНЦ агроэкологии РАН по оценке адаптированного генофонда для защитного лесоразведения будут использованы для разработки мероприятий по сохранению биоразнообразия и рациональному использованию хозяйственно ценных растений; с учетом полученных данных отобраны перспективные виды для обогащения защитных лесных насаждений Кулундинской степи. On the example of the Kulunda arboretum the materials of monitoring of introduction resources of trees and bushes are given. The success of their introduction into the culture of protective afforestation is based on a detailed study of ecological and biological features, the experience of introduction in new conditions. Due to the increased anthropogenic load in recent years, the range of woody plants used in the protective forest plantations of arid areas requires updating. The problem statement includes the allocation of a valuable gene pool for the creation of seed bases and the cultivation of adapted planting material. It is shown that in the conditions of the Kulunda steppe the introduced species in the protective afforestation are not widely used yet, the range of tree species is poor (Betula pendula Roth., Populus balsamifera L., Pinus sylvestris L., Larix sibirica Ledeb., Salix fragilis L.). Accompanying woody plants are presented by Acer negundo L., Malus pallasiana Juz., Ulmus pumila L. Other tree species are used in protective afforestation on a limited scale. The purpose of the evaluation introduction the sustainability of the gene pool of Salted arboretum on the basis of a comprehensive monitoring and study their biological features under conditions of Kulundinskaya steppe for protective afforestation. Kulundinsky arboretum was established in 1977, it is located on the territory of the West Siberian agroforestry experimental station (plot 49098 m2, cadastral number 22:23:010003:0014). Type of soil – chestnut, light-loamy. The main reserves of humus are concentrated in the upper horizon and with a depth decrease from 2.7 to 0.6%, the depth of groundwater 5-6 m. It was revealed that the species composition of trees and shrubs of the Kulundinsky arboretum includes 143 taxa from 52 genera and 25 families. Among the economically valuable generic complexes are representatives of the family Rosaceae. It is established that the representatives of the family Rosaceae, as an introduction resource for the enrichment of forest reclamation complexes and the formation of comfortable living conditions of the population, is one of the largest in taxonomic composition of wood species and important for multifunctional use. Methodical approaches to carrying out monitoring of introduction of resources, the proposed method of calculation introduction the resistance of plants to new conditions including the characteristics group (winter hardiness, drought tolerance, pobegoobrazovatelnost ability, growth in height, generative development, possible method of propagation in culture) and the ratio of collection Fund on indicators and the dimensions of the scales. Materials on monitoring of introduction resources of the Kulundinsky arboretum of the Federal CENTER of Agroecology of the Russian Academy of Sciences on assessment of the adapted gene pool for protective afforestation will be used to develop measures for biodiversity conservation and rational use of economically valuable plants; based on the data obtained, promising species for the enrichment of protective forest plantations of the kulundin steppe were selected.

Защитное лесоразведение в засушливых условиях Поволжья связано с использованием интродуцированных древесных растений. Несмотря на большой опыт защитного лесоразведения, состояние всех видов насаждений в регионе нельзя считать удовлетворительным. Причины: ошибки в подборе деревьев и кустарников, в оценке генофонда, в разработке ассортимента. Отсутствие научно обоснованного регламента повышения биоразнообразия древесных растений в защитных лесных насаждениях Поволжья приводит к инвазиям. На примере коллекционных дендрологических участков (Волгоградская, Самарская области) приведены материалы по выявлению потенциальных рисков последствий интродукции для повышения биоразнообразия защитных лесных насаждений. Цель – научное обоснование регламента подбора интродуцированных деревьев и кустарников для повышения биоразнообразия защитных лесных насаждений в засушливых условиях. Разработанный регламент обогащения дендрофлоры включает алгоритм количественного и качественного улучшения ассортимента и выбор лучшего варианта из возможных с использованием кластерного подхода, системы методов и критериев. Для выполнения поставленных задач научно-исследовательские работы были сконцентрированы на биоресурсах деревьев и кустарников объектов Федерального научного центра агроэкологии, комплексных мелиораций и защитного лесоразведения Российской академии наук (ранее ВНИАЛМИ) и его филиалов. Генофонд деревьев и кустарников представлен 700 таксонами. В статье обосновано использование в защитных лесных насаждениях Поволжья интродуцентов многоцелевого назначения (родовые комплексы семейств Rosaceae, Caprifoliaceae, Oleaceae, Fabaceae). Представлен реестр родов экономически важных семейств коллекционного фонда. Они обладают адаптивностью, включают экономически важные группы. Расширение биоразнообразия древесной растительности защитных лесных насаждений посредством введения кустарников различных форм роста (высоких, средних, низких) способствуют улучшению экологических условий и сохранению биологического разнообразия ландшафтов. Представлены материалы мониторинга дендрологических коллекций и экспериментальных популяций, образующих самосев. Установлено, что при конструировании защитных лесных насаждений различного целевого назначения необходимо использовать разнообразие перспективных и экономически важных деревьев и кустарников (лесомелиоративных, декоративных, плодово-ягодных, медоносных, лекарственных). Для лесомелиоративного обустройства деградированных экосистем рекомендовано 168 видов деревьев и кустарников. Для создания насаждений на малопродуктивных землях внедряется 90 видов интродуцированных кустарников многоцелевого назначения. Прогноз перспективности генофонда древесных растений для защитного лесоразведения базируется на многолетнем агроэкологическом мониторинге родовых комплексов дендрологических коллекций Федерального научного центра агроэкологии, комплексных мелиораций и защитного лесоразведения Российской академии наук и включает создание фонда посадочного материала древесных видов с учетом экологичности, хозяйственной пригодности и инновационной привлекательности. Protective afforestation in the arid conditions of the Volga region is associated with the use of introduced woody plants. Despite the great experience of protective afforestation, the condition of all types of plantings in the region cannot be considered satisfactory. Reasons: errors in the selection of trees and shrubs, in the evaluation of the gene pool, in the development of the assortment. The lack of scientifically sound regulations for increasing the biodiversity of woody plants in the protective forest plantations of the Volga region leads to invasions. On the example of collections dendrology plots (Volgograd and Samara regions), materials are provided to identify potential risks of the consequences of introductions to enhance the biodiversity of protective forest plantings. The goal is the scientific substantiation of the regulations for the selection of introduced trees and shrubs to enhance the biodiversity of protective forest plantations in arid conditions. The developed procedure for enriching dendroflora includes an algorithm for quantitative and qualitative improvement of the assortment and the choice of the best option possible with the use of a cluster approach, a system of methods and criteria. To carry out the tasks set, the research work was concentrated on the bioresources of trees and shrubs of the facilities of the Federal Scientific Centre of Agroecology, Complex Melioration and Protective Afforestation of Russian Academy of Sciences (formerly VNIALMI) and its branches. The genefond of trees and shrubs is represented by 700 taxa. The article substantiates the use of multi-purpose plants in protective forest plantations (Rosaceae, Caprifoliaceae, Oleaceae, Fabaceae) of the Volga region. The register of genera of economically important families of the collections fund is presented. They have adaptability, they include economically important groups. Expanding the biodiversity of tree vegetation of protective forest plantations through the introduction of shrubs of various forms of growth (high, medium, low) contribute to improving environmental conditions and preserving the biodiversity of landscapes. Materials of monitoring dendrological collections and experimental populations that form sowing of young plants are present. It is established that when designing protective forest plantings for various special purposes, it is necessary to use a variety of perspective and economically important trees and shrubs (forest meliorative, ornamental, fruit and berry, honey, medicinal). For forest reclamation of degraded ecosystems, 168 species of trees and shrubs are recommended. For the creation of plantings on unproductive land, 90 species of introduced shrubs of multi-purpose use are being introduced. The forecast of the perspective of the gene pool of woody plants for protective afforestation is based on long-term agroecological monitoring of the generic complexes of dendrological collections of the Federal Scientific Centre of Agroecology, Complex Melioration and Protective Afforestation of Russian Academy of Sciences, and includes the creation of a stock of planting material for tree species, taking into account environmental friendliness, economic suitability and innovative attractiveness.

At present, high-level attention is paid to the issues of the role, significance, optimal use of soils, their protection and combating degradation. By introducing the Sustainable Development Goals at the national level, Ukraine is obliged to introduce new programs and projects that, in practice, will have macroeconomic stability, ecological balance and social cohesion. During scientific research on the multifunctional role of protective forest plantations, which at one time were created on eroded territories, which include gully-ravine lands, to revive the properties of soils, work was carried out to substantiate their regenerative function. To achieve this goal, 90 soil-forest typological stations were established in erosion control plantations of various periods of plant growth and development with the selection of 270 soil samples. A study of their water-physical and agrochemical properties was carried out with the processing of the data obtained by statistical methods. Based on the analysis of scientific literary sources, the study of successful production experience and our own research on anti-erosion plantations to determine their impact on soil properties and the environment, qualitative stages of the ecological restoration of eroded soils have been developed. Changes in the age periods of growth and development of woody plants in protective forest plantations created on gully-ravine lands lead to a gradual step-by-step ecological restoration of eroded soils. Thus, a clear correlation of the age periods of growth and development of woody plants with the qualitative stages of ecological restoration of eroded soils was obtained. The selection of research objects provided for taking into account the same technology for creating anti-erosion plantings, growth and development in the same conditions, corresponding to five age periods of growth and development of woody plants. In each age period, qualitative changes occur during the growth and development of the vegetation cover, as well as quantitative changes in indicators characterizing the properties of the soil, which are presented in comparison with the control, which is the pasture. The main functions of these plantings are presented. Attention is paid to all age periods of growth and development of anti-erosion plantings in terms of forest measures for the successful cultivation of anti-erosion plantings and their effective action. The stages of ecological restoration of eroded territories are clearly consistent with the identified age periods. The prospects for understanding the process of restoring protective vegetation cover, including forest plantations, and their direct impact on the properties of eroded soils are opening up. Keywords: erosion processes, eroded soils, anti-erosion role, periods of development, qualitative stages, soil properties, hydraulic roughness.

The problem of optimization of ecological conditions of urbanized and agricultural areas of the arid zone is especially urgent nowadays. Severe forest conditions make it necessary to optimize the environment due to the protective plantations of different types and ecological categories. The use of woody plants unusual for a given area as part of multifunctional stands is one of the main methods for increasing the ecological capacity of the territory, changing the structure and population of insects. The study was conducted in Volgograd, Samara and Rostov regions. By the degree of biotic potential accumulation among the trees adapted in the arid region, plants of the Ulmaceae, Rosaceae and Fabaceae families are distinguished. The introduction of woody vegetation into new territories is also accompanied by the penetration of alien species of pests. Currently, among the phyllophages of woody plants used in landscaping various landscapes, there are invader insects. In urban areas, these species are particularly closely associated with Robinia pseudoacacia L. The most numerous as part of the pests of assimilation apparatus of this plant are Obolodiplosis robiniae (Haldeman, 1847) and Nematus tibialis (Neuman, 1837). Dissemination of Robinia by these insects in the protective forest plantations varies greatly. In the roadside forest plantations and the agroforest plantations in the composition of dendroflora the species of the family Ulmaceae are predominant. Among the invasive species that appeared in them is Aproceros leucopoda (Takeuchi, 1939); in these stands, it almost completely destroys the elm foliage. In the crowns of trees of recreational landscaping, single individuals of this species are found. Among the dendrophages of the stands of urbanized and forest-agrarian landscapes, open-living leaf-eating insects giving outbreaks of mass reproduction (Xanthogaleruca luteola, Dicranura ulmi, Cladius ulmi, Aproceros leucopoda) stand out. Wide spread and increase in the number is observed in Obolodiplosis robiniae and Fenusa ulmi.

Reclamation of land on community land funds and the hydrographic network contributes to the most effective means of protecting the soil from water erosion. However, the condition, growth, and productivity of the protective forest stands themselves depend on the species composition. Many years of studies have clearly shown that not all tree species and shrubs can successfully grow on washed soils. Extensive scientific material provides a description of the growth and current status of the studied species, a detailed taxation description of the forest plantations. Of particular value are those species that can grow on eroded lands and protect the soil from erosion.

Spiders of the genus Philodromus Walckenaer have the flattened body and laterigrade legs of all Thomisidae, or crab spiders, yet lack most of the specializations of the more typical genera in the family. The latter, which comprise the subfamily Thomisinae, are characterized by strong, heavy bodies, prominent eye tubercles, a marked disparity between the length of legs I and II as opposed to that of III and IV, rotund abdomens, and a slow gait (Gertsch, 1939). In Philodromus and throughout the Philodrominae we find a lithe, smooth body that is weakly spined and covered with soft, recumbent hair (Fig. 22). The legs are slender and nearly equal in lengh; These spiders typically lead an active, predatory life on surfaces and in crevices of woody plants. They are able to exploit this type of habitat largely because their legs are equipped with well-developed scopulae and claw tufts.

Abstract Protective forest plantations (PFP) play an essential functional role in the operation of anthropogenic landscapes (AL). A study of processes in the system “PFP-AL” was conducted in the Boguslav agroforestry state, Kyiv region, Ukraine, to maintain sustainability. A method of ecological monitoring has been proposed to achieve environmental equilibrium stability. The calculations show the stable state of the ecosystem. A graphic-analytical method for quantitative assessment of the potential adverse effects of natural resource management has been proposed. It is shown that additional compensation of adverse effects is necessary, which can be performed by green structures.
