The author investigated, recorded, observed and analyzed the major wildflowers in Mount Huangshan---the natural and cultural heritages listed by the ESC0 of UN for the first time. On the basis of their desirable characteristics, more than 300 wild ornamental species are divided into 8 categories -–-historical old trees, rare and endangered species, evergreen ornamentals, blooming trees and shrubs, plants with colored foliage and fruit in fall, vines, herbaceous ornamentals and ground covers, and ornamental ferns. Mount Huangshan is one of the richest regions of native ornamentals in Eastern China and the most famous natural beauty in Pan-China. There are about 1500 wild landscape plants in and around it. Finally the paper puts forth some proposals and methods for introduction and utilization of wild ornamental plants. That is, investigation, classification,acclimatization and cultivation of them, and building a sort-out botanical garden for the germplasmic preservation and the flourishing landscape tourism.

Впервые в мире создана популяция зубров на территории 60 градусов северной широты. В новых климатических условиях разведения и сохранения зубров определены и проанализированы факторы существования вида на севере Европейской части РФ. Выявлены признаки, динамика численности, которые являются составной частью системы, предназначенной для управления биоразнообразием. Интродукция, являясь процессом введения в экосистему нехарактерных для нее видов, может усиливать изменения биоценозов как положительно, так и отрицательно. Насколько быстро и успешно проходит процесс адаптации заселенного вида, и усматривается его влияние на окружающую среду зависит дальнейшее существование зубров и в целом биоразнообразия. В статье обсуждаются вопросы взаимоотношения зубров с другими видами копытных и хозяйственной деятельностью человека, а также дальнейшим использованием зубров в сельскохозяйственном производстве. Пластичность зубров, выявление изменений и их анализ при вселении видов в новые условия обитания необходимы не только для определения развития или деградации биоценозов и в целом экосистемы, но и прогноза социально-экономических последствий интродукции как одного из методов сохранения редких и исчезающих видов фауны.For the first time in the world, a bison population has been created in an area of 60 degrees north latitude. In the new climatic conditions of breeding and preservation of bison, the factors of the species existence in the north of the European part of the Russian Federation are identified and analyzed. The signs, dynamics of abundance, which are an integral part of the system designed to manage biodiversity are identified, since the preservation of biological diversity on the planet is one of the main problems of our time. Introduction, being the process of introducing non-typical species into an ecosystem, can enhance changes in biocenoses, both positively and negatively. The question posing sounds especially when it comes to such a large hoofed animal as the European bison. How quickly and successfully the process of adaptation of the universe takes place and its environmental impact is seen depends on the continued existence of bison and biodiversity in general. The article discusses the relationship of bison with other types of ungulates and human activities, as well as the further use of bison in agricultural production. How these issues will be resolved positively depends on the future of these animals. Thus, the plasticity of bison, the identification of changes and their analysis, with the introduction of species into new habitat conditions is necessary not only to determine the development or degradation of biocenoses and the ecosystem as a whole, but also to predict the socio-economic consequences due to the introduction as one of the methods of preserving rare and endangered species of fauna.

The article deals with one of the most relevant topics of the modern city and ecology - the problem of landscaping in Volgograd. The city is characterized by an industrial urbanism, with a high concentration of population, saturation of production facilities and vehicles, which contributes to a high level of negative impact on the environment. The pace of greening of the city lags behind the pace of construction of the residential sector, and the existing green spaces do not meet the sanitary and hygienic, aesthetic requirements. The prospects of this problem are determined, the existing green spaces are considered, data on the climatic conditions of the city and the ecological situation are given. Improvement in the field of landscaping is associated with the scientifically sound placement of green spaces, taking into account all the factors that affect the growth and development of plants in the urban environment. Unfortunately, due to the uneven distribution of the assortment of trees and shrubs, the species composition of the central streets and squares of the city is extremely poor. The study focuses on the role of the botanical garden in urban landscaping and aims to create recommendations for the sorting of tree and shrub plants for urban landscaping. As a result of the analysis of the assortment of ornamental plants of the open ground of the botanical garden, the article proposed species and varieties of woody and shrubby plants that have passed the introduction tests for more than 5-10 years. Recommendations for sorting are aimed at improving the ecological situation of the city and greening the recreation areas of citizens. The proposed list of tree and shrub species cannot fully solve the problem of greening the city, but it will help to significantly enrich the composition of tree and shrub plants.

Abstract. The article presents the results of an experimental assessment of the peculiarities of the water regime of 9 species of the genus Iris L. growing in the South-Ural Botanical Garden-Institute UFRC RAS (I. sibirica L., I. pseudacorus L. ‒ species of native flora, I. aphylla L., I. biglumis Vahl., I. lacteal Pall., I. orientalis Mill., I. ruthenica Ker-Gawl., I. setosa Pall., I. spuria L. ‒ introduced species). The purpose is a comparative evaluation of the main parameters of the water regime within the generic complex and depending on the detection of meteorological factors in different phenological periods. Methods. Studies were performed in growing periods 2019–2020’s physiological using conventional techniques (artificial saturation method and wilting). Made a detailed analysis of daily and seasonal dynamics of the water regime of the three parameters: the total water content, water-holding capacity, water scarcity. Typical forest species Convallaria majalis L. was investigated for a comparative analysis of water regime indicators. Results. The similarities and differences in the peculiarities of the water regime were established between the studied species, the dependence of the indicators on meteorological conditions was revealed. According to the type of water regime cultivars were divided into four groups: a flexible water-quiet mode ‒ I. pseudacorus, flexible water-tight mode ‒ I. sibirica, I. ruthenica, stably-calm water mode ‒ I. aphylla, I. biglumis, I. setosa, stably-tight water mode ‒ I. spuria, I. lactea, I. orientalis. Among the studied parameters of water scarcity was the most dependent on meteorological factors. Scientific novelty. The study helps to identify ecological and physiological adaptations of exotic species in comparison with the native species that could become the basis for assessing the prospects of growing in the culture and conservation of rare and endangered species.

The high mountainous beech (Fagus orientalis) forests of Dagestan which are a refugium of the species with oceanic/suboceanic distribution in the arid conditions of the East Caucasus have been studied for the first time, and 140 species of lichens, lichenicolous and non-lichenized fungi growing on beech have been revealed. Among them 3 species (Leptogium burnetiae, Lobaria pulmonaria, and Ricasolia amplissima) are endangered lichens included in the red data book of Russia. Seven species (Abrothallus nephromatis, A. peyritschii, Biatora beckhausii, Biatoropsis usnearum, Bryoria vrangiana, Dactylospora lobariella, and Usnea fragilescens) and 2 genera (Biatoropsis and Ramonia) are reported for the first time for the East Caucasus; 10 species (Collema nigrescens, C. subnigrescens, Gyalecta fagicola, G. herculina, Lecanora intumescens, Leptogium burnetiae, L. cyanescens, Melanohalea elegantula, Nephroma helveticum, and Ramonia luteola) and the genus Biatora are new for Dagestan. The record of Ramonia luteola is the second for Russia and the Caucasus. Most of the lichens are with trebouxioid photobiont, cyanolichens are represented by 20 species, lichens with trentepohlioid photobiont — by 14 species. Reproductive strategy by spores is prevailing. Vegetative diaspores are formed by 51 species of which 46 are fruticose and foliose. The species from Lobarion pulmonariae community are revealed. The presence of rare and endangered species shows a high value of studied community for nature protection.

The collection fund of rowan trees of the Mountain Botanical Garden, located at an altitude of 1700 m above sea level (Gunib plateau), includes 30 species, 5 varieties, cultivars and hybrid forms. There are 6 species of rowan in Dagestan, introduced from natural habitats, of which three species are included in the Red Book of Dagestan, and are included in the Red List of Endemic Species of the Caucasus (IUCN). As a result of the search and research work, new locations of four rare and endangered species of rowan ( S. caucasica, S. graeca, S. kusnetzovii, S. subfusca ) that are threatened with extinction in Dagestan were identified. The geographical coordinates of the exact location of rowan species are marked, and maps of the species' range on the territory of the Republic of Dagestan are compiled. For further monitoring observations, the total number of species was clarified, the biomorphological indicators and the age structure of the populations were studied. Under the conditions of culture, they were propagated by seeds and vegetatively by grafting on the rootstock of S. aucuparia .
