Floristic Characteristics

The paper considers ecological-floristic characteristics of the specially protected natural area Kostinskie Loga, located in the southern part of the Samara Region (Bolshechernigovsky and Bolsheglushitsky Districts). The research area belongs to the subzone of fescue-feather grass steppes. The flora is represented by 240 species of vascular plants belonging to 160 genera, 49 families, 2 classes and 1 division. Ecological-cenotic analysis was used to assess the ecosystem diversity of the nature sanctuary. The leading groups for phytocenotic affinity are identified: steppe (65 species; 27,1%) and meadow-steppe (54 species; 22,5%), which indicates a good preservation of steppe biomes and demonstrates landscape features of the nature sanctuary. The low value of the synanthropization index (15,8%) reflects a moderate level of anthropogenic load. The adventive component of the flora is represented by 30 plant species (12,5%), among which the degree of naturalization is dominated by epecophytes (10,8%), the time of introduction by neophytes (6,7%), the methods of introduction are dominated by xenophytes (27 species; 11,3%). The analysis of flora identified 6 species included in the Black book of Central Russia (Acer negundo, Atriplex tatarica, Cyclachaena xanthiifolia, Hordeum jubatum, Elaeagnus angustifolia, Xanthium albinum). The introduction of alien plants into natural communities occurs due to pasture digression in areas bordering the territory of the nature sanctuary. In general, the degree of anthropogenic transformation of the flora in most of the territory is expressed slightly, the vegetation cover retains natural features inherent in the steppe zone. A high degree of preservation of steppe communities with a significant participation of rare representatives of flora (14,6%) creates prerequisites for the organization of one of the steppe reserve sections of the Samara Region.

Degraded Pastures

Intensive development of the steppe communities of Kulunda, located in the southern part of the West Siberian lowland in the XX century led to a significant anthropogenic transformation of all steppe ecosystems. Representatives of the legume family, which is the most important component of steppe grasses, have almost disappeared from the grasslands. The research was conducted on the territory of the Mikhailovsky district of the Altai territory, on the lands of LLC KKH «Partner» in the environs of Poluyamki village scince 2013-till present days climatic conditions of dry steppe zone of Western Kulunda. The aim of the work was to evaluate representatives of the legume family for ecological reclamation of Kulunda steppe pastures. The experiment was performed on 2 degraded fenced steppe areas (10 x 10 m) corresponding to the third stage of pasture digression. Winter sowing of legumes was carried out: cicer milk vetch (Astragalus cicer L.), sainfoin milk vetch (A. onobrychis L.), furrowed milk vetch (A. sulcatus L.), bird’s foot trefoil (Lotus corniculatus L.), sickle alfalfa (Medicago falcata L.), hop alfalfa (M. lupulina L.) and late spring sowing: cicer milk vetch and sainfoin, bird’s foot trefoil by tapping into the sod. Monthly growth dynamics of sown plants (number of shoots per m2, height, phenology) was recorded, and the feed value of aboveground biomass was established. It was found that the drought-resistant species of alfalfa sickle has a significant biomass, is short-lived in the grass stand and requires re-sowing every 4 years. Hop alfalfa is recommended for improving degraded pastures, but due to its short ontogeny, it needs to be re-sown every three years. Among milk vetches, sainfoil milk vetch is the most promising – a long-rooted, rod-rooted polycarpic that increases its area due to numerous underground rhizomes. The greatest nutritional and energy value was possessed by the phytomass of bird’s foot trefoil and sickle alfalfa.

The characteristic of the spread of herbal ecosystems in the agrolandscapes of the Valui district of the South Russian province of the steppe zone of the Central Black Earth of Russia is given. Tramped pastures (with narrow-leaved bluegrass, sheep fescue, motley grass) predominate on the site of the indigenous (rich-motley grass, sheep fescue, feather-grass) Donetsk and middle-Don steppes.

AbstractThe sustainable urban redevelopment project to protect biodiversity was developed to regenerate the external spaces of an ancient rural farmhouse, Villa Framarino, in the regional Natural Park of Lama Balice, a shallow erosive furrow (lama) rich in biodiversity, between two suburbs of the city of Bari (Apulia, Italy) and close to the city airport. This work includes a complex system of activities aimed not only at a spatial revaluation, necessary to relaunch the urban image, but it is accompanied by interventions of a cultural, social, economic, environmental and landscape nature, aimed at increasing the quality of life, in compliance with the principles of sustainability and social participation. One of the means to revitalize a territory subject to redevelopment is the planning of events and activities of socio-cultural value that involve the population to revive the sense of belonging to the territory and the community and at the same time to protect the biodiversity of the urban park of the protected natural area.

The article discusses the social charity of “local community” in Ust -Sysolsk in the second half of the XIX century. We define “local community” as a voluntary, self-determining citizens association, designed or not properly executed legally for the solution of urgent problems of non-productive and non-commercial nature. The aim of the work is to study public charity as an activity of “local community” in Ust-Sysolsk in the second half of the XIX century. The provisions of the work can be used for educational and methodological materials on the subject “History of Finno-Ugric regions and countries”, “History of everyday life”, “History of the Komi Republic” and others. The research methodology is based on a systematic approach, which includes structural, legal, historical and other methods of research. The materials are based on published and unpublished historical sources, such as legislative materials, statistics, documentation, as well as archival materials. Central Russia and the Urals had already introduced charities in the mid of XX century, while in the research area public charity was just beginning and was manifested through the social work of the Russian Orthodox Church, amateur associations and companies. Forms of public charity varied: fundraising, purchase of tools, equipment and materials for events and others. Public charity, “local community”, in Ust-Sysolsk developed within the framework of modernization processes of the second half of the nineteenth century. It led to the evolution of «local community» into a civil society. The emergence of new public organizations and active public charity contributed to the development of new forms of self-organization. In the city of Ust-Sysolsk, there was an upsurge of public life and public performance. The appearance of self-governing organizations “local community” was facilitated by the loyal policies of the district and provincial government. As historical sources show that we can talk about mutual understanding and cooperation between the authorities and the “local community”. Carrying out public charity, it provided public functions of traditional culture maintenance, the organization of leisure, cultural and educational activities.

Survival And Growth

In 1997, a restoration of Pinus culminicola was established under three exclusion areas: E1 = cattle plus small mammal exclusion, E2 = cattle exclusion and E3 = no exclusion (free range), in the Cerro El Potosi Protected Natural Area, located in Nuevo León, Mexico. The objective of this study was to determine the survival rate and the increase in diameter and height of Pinus culminicola individuals at three and 17 years after planting. The results show differences between 2000 and 2014 in survival rate and diameter and height growth in the three exclusion areas; E1 and E2 recorded higher averages. The main causes of mortality in this species are attributed to extreme weather conditions and the damage caused by cattle and small mammals.
