This article presents information about the state of the herbaceous vegetation of the Rossoshansky district of the Voronezh Region. The studies were conducted on 2 trial sites. For this purpose, the eye — measuring method of ground cover accounting was used- accounting for the abundance of individual representatives of the ground cover on the Drude scale and on the Zh. Brown-Blanquet scale. Thanks to this, it was possible to identify plant species that predominate in this area, and species that occur only in a single instance.

State Of The Environment

Despite the fact that the most changes in lists of threatened species reflect changes in knowledge rather than changes in conservation status, the lists continue to provide social and legal mandates for conservation; they are used to report on the state of the environment and to guide the allocation of scarce resources. There is a substantial under-representation of non-vascular species in threatened plant lists, reflected in an absence of documented extinctions among fungi and algae. Turnover in the composition of extinct flora lists in Australia suggests that the lists of threatened species may not be sufficiently reliable to form the basis for reporting on the state of the environment. They are of limited use in distinguishing between levels of threat and may not be a reliable guide for the allocation of scarce conservation resources among plant species. Systems for listing threatened species create a feedback loop, responsive to the subjective preferences of scientists, largely unresponsive to underlying true threats, self-perpetuating and accentuating bias with each iteration. Other tools, including formal decision approaches and the acquisition of new kinds of data, are needed to fill the roles.

Compared to other groups of organisms, plants require distinctive approaches in their conservation because of their keystone roles in ecosystems and economies. The state of the whole plant cover of the Earth should be of concern to conservationists – for its capacity to ensure the survival of plant species, deliver ecosystem services (locally to globally) and provide produce from plants in ecologically sustainable ways. The primary targets of attention in ecosystem-based plant conservation are the relationships between people and plants, as relevant to every locality, rather than the species-centric approach of conventional plant conservation. Moving plant conservation to an ecosystem-based approach will require the development of training programmes for field practitioners and of information systems for their use.

Species Analysis

In swamp distribution, dominance and survival of a species is very much governed by the soil moisture and period of flooding. The present study was conducted to classify the communities and plant species, and to have an idea about various associations of plants present in the swamp with respect to soil moisture. Two way indicator species analysis (TWINSPAN) classified the communities into four and plant species into eleven groups. The communities with least soil moisture were the first to be segregated and with highest soil moisture last. Similarly, the species growing in drier condition was clustered separately from the moisture loving indigenous species.

The Karatag gorge is one of the natural areas where valuable genetic resources (wild, fruit and many valuable species) are preserved. A characteristic feature of the region is the richness of the diversity of flora and vegetation, where the main formations of Tajik vegetation are noted (maple, hazel, almond, frame, juniper). The article summarizes the results of the authors’ field research on the study of the state of xerophilic forests in the Karatag gorge. For the first time, the authors cite original materials on the phytocenology of all formations of this type of composition. According to the results of our research, the Shibleak communities in the study area are distributed in high-altitude belts from low-hilly 600–800 m to middle mountains 800–1800, 2000 m. The main formations of this type in the study area are: Acer regelii, Crataegus pontica, Celtis caucasic, Pistacia vera, Amygdalis bucharica, Ampelopsis vitifolia, Atraphaxis pyrifolia. As a result of the study, 340 plant species, 6 formations and more than 25 vegetation associations were identified in the composition of the flora of this type of the study area.

The Russian Federation

The timber industry complex of the Russian Federation ranks fourth among all branches of the country, because in terms of forest area Russia ranks first in the world (8148895 km2), which is about 49.76% of the total area of Russia. The timber industry complex is a complex system and consists of four components (logging industry, woodworking industry, pulp and paper industry, wood chemical industry). Particular attention is paid to this industry in Eastern Siberia, Western Siberia and the Far East, because these regions have the greatest forest cover. In sparsely wooded regions, the timber industry is not a priority and little attention is paid to it, both by the state and by investors. In this article, we examined the state of the forestry complex of the Voronezh region, the forest cover of this territory is only eight percent of the entire territory of the country, all forests are protective, therefore the volume of timber is carried out thanks to sanitary felling and is about 285 thousand m3. In this region there are about 20 large and medium-sized enterprises involved in the timber industry and about 40 small private enterprises. The main problem of the timber industry complex in a low-wooded region is low-quality products, imperfection of regulatory legal acts at the regional level, and lack of investment. In this regard, measures were proposed that will contribute to the development of the timber industry complex in the low-forest region.

RESUMO The permanence of a plant species in a forest community depends on its number of specimens and its distribution in the various sizes of individuals, including seedlings. Seedlings and seeds from a forest remnant in Pirassununga were collected and analyzed for the degree of threat, possible height of the adult individual, occurrence in phytophysiognomies and region and morphological aspects. 116 seedlings available in 39 morphospecies were collected, and the germination of collected seeds provided 40 species. The present study brought news regarding the morphological aspects, the identification and the distribution of seedlings of tree species in a riparian forest area in the Mogi Guaçu River Basin and in the State of São Paulo.

The mixing of two immiscible phases is a process commonly seen in many industrial applications. Whether it is desirable (e.g. mixing of ingredients in chemical or food industry) or undesirable (e.g. sediments or contaminants in water purification) process, it has to be taken into consideration and a detailed description would be beneficial to any end product. This paper deals with a method for observing the volume ratio of two immiscible phases from the state of total separation to the state of a homogenous mixture using industrial Electrical Impedance Tomography (EIT) system ITS p2+. This paper also shows a great advantage in combining the EIT measuring method with a theoretically derived formula. It is used to calculate the concentration of a non-conductive phase in the final mixture using the initial and final conductivity values. The authors were also able to show a possibility to successfully use the formula in situations, where the initial conditions for it are not fully met.
