The aim of the study was to make an inventory and describe the localities of interesting species inhabiting the segetal communities of the Turobin commune, which are regarded as endangered in Poland and Europe. The paper presents results of a field study conducted in 2011-2013 in crop fields, located on brown soils and rendzinas. Phytosociological relevés were made with the Braun-Blanquet method at the sites of phytocoenoses comprising interesting and endangered species. The habitat was assessed with the use of soil-agricultural maps, and soil pH was measured at the site where the phytosociological relevés were taken. In the Turobin commune, 32 interesting species were found; some of them are considered rare and endangered in Poland. In this group, the occurrence of Asperugo procumbens, regarded as an endangered species and included in the red list of vascular plants, is noteworthy.

As a result of human activity, the rate of extinction of species is now 100 to 1000 times faster than under natural conditions [1]. According to the FAO, 75% of the genetic diversity of agricultural crops worldwide has been lost since 1990. In Poland, about 100 species of field weeds are in danger of extinction. Archaeophytes growing on heavy calcareous soils, which are characteristic of the Lathyro-Melandrietum noctiflori, Caucalido-Scandicetum, Kicxietum spuriae communities, and weeds associated with the cultivation of flax, are particularly endangered. Halting the loss of rural biodiversity is a priority for the EU’s environmental protection strategy. Research aimed at assessing the infestation status of the weed agrophytocoenoses, located on rendzinas in the Lublin Province (Poland), has been conducted since 1997. The research was carried out using the Braun-Blanquet phytosociological method. Lublin Province is located in the south-eastern part of Poland. Here, there are good conditions for agricultural production. Agricultural land covers 57.9% of the total area of the voivodeship, of which 99.3% is agricultural land suitable for a good standard of farming. In such favorable environmental conditions, agriculture in the Lublin Province is characterized by an unfavorable structure of farms: 55.6% of more than 180,000 farms are those with an area under 5 ha. Such a large fragmentation of farms results in a low profitability of the agricultural sector, which results from extensive farming. Research has shown that low-input agriculture is conducive to the preservation of rare and endangered species of segetal flora [2]. Muscari comosum—a critically endangered (ER) species under strict protection—were found on several sites in the study area. Several sites of Caucalis platycarpos and Galium tricornutum, also recognized as ER species, were found in heavy rendzinas. Moreover, numerous sites of such rare species as Adonis aestivalis, Anthemis tinctoria, Thymelaea passerina, Lysimachia arvensis, Chaenorhinum minus and Euphorbia exigua were also identified. Research on the state of the population of rare species is a key challenge for scientists, because only knowledge about this will provide a basis for future relevant actions aimed at maintaining biodiversity and restoring degraded ecosystems [The poster presentation].

The area of the Nízký Jeseník Mts. is, among other things, well known for its shale roofing tiles since the 18th century. In places where shale was intensively or extensively exploited until 1945, abandoned areas after mining works remained. In general, every mining is perceived as a activity of landscape degradation by the public. However, these indelible traces of shale mining in the form of various mining-related objects (e.g. abandoned quarries, quarry ponds, shafts, drains etc.) are also gradually becoming places that are colonised by unique plant and animal communities. There are very interesting species bond to specific environmental conditions of post-mining landscape, with frequent rare and endangered species. People have also become ‘new’ colonisers in the case of the shale landscape.

The processed set of phytosociological relevés indicated that at the present time the field weed associations are composed particularly of species of wide ecological amplitude. The rare and endangered species appeared only on localities usually not much affected by chemicals. Most of the endangered species of field weeds were found to survive primarily on small private farms, in the headland of fields or on field edges near the natural reserves.The results indicated that the type of crop had a significant effect on the composition of the current aboveground vegetation. There is a close relationship between the type of crop and the applied cultural practice. Its effect is much more important than the effect of the overall method of management. However, long-term application of herbicides may eliminate some weed species from the seed bank and as a consequence also from the current vegetation. That is the reason why crop rotation is so important for preserving the species diversity of weeds in tandem with limited applications of herbicides.

The information about the distribution of 28 rare and endangered species of vascular plants under Federal and regional security, registered in 2018 on the territory of the Volgograd oblast under the Federal and regional security is given. Among them, 2 species (Crambe tataria Sebeok и Stipa zalesskii Wilensky ex P. A. Smirn.) are included in the List of Threatened plant species of Europe. Each location is linked to the grid of Atlas Flora Europaea. The obtained materials about the distribution of rare and endangered species of vascular plants represent an important data for long-term monitoring and also for environmental management measures at the regional level.

Data about distribution of Bangia atropurpurea (Roth) C. Agardh indicate that this species was found on relatively small number of localities in freshwaters in Europe and world. In Red List of Algae, in some countries, this species is defined as a extinct (Ex) (Poland) or as endangered (En) (Slovakia). In this study, morphological and ecological characteristics of rare and endangered species B. atropurpurea that was found on three localities in Serbia: in Trgoviski Timok River (East Serbia), Gvozdacka Reka River (West Serbia) and Raska River (South-western Serbia). The Raska River is new find of the species B. atropurpurea.

Among the conservation measures related to the preservation of plant diversity, an important place belongs to the creation and preservation of rare and endangered species in the crop conditions. Thus, the species Silene hypanica Klokov is under threat of extinction. This relict and endemic species is listed in the Red book of Ukraine, the European Red list, and 6th Resolution of the Berne Convention. Prospects for the conservation of this species are related to the study of its viability and require the development of effective methods of reproduction, in particular in vitro crop. The article presents the results of studies of one of the breeding stages in vitro – rhizogenesis of S. hypanica esplants and its dependence on the concentrations of β-indolyl butyric acid in nutrient media (0,1; 0,5; 1,0; 1,5; 2,0 mg / l), followed by adaptation of regenerating plants to ex vitro conditions. The study showed that the active process of rhizogenesis occurred due to the addition of β-IMC to the nutrient medium at a concentration of 0.5 mg/l and contributed to the production of 86.4 % of rooted regenerating plants. Transplanting rooted plants into peat disks and then growing them in containers contributed to the successful adaptation of rooted plants.

The author offers mapping and geoecological analysis of the Russian Federation regions presence in the state program “Environmental Protection”. The unequal distribution of the program’s targets and activities in different regions is revealed. A considerable number of relevant environmental problems for several mentioned regions have not been reflected in the program. It is important to increase the area of specially protected natural areas for a significant number of subjects of the Russian Federation. The status “part of the territory occupied by specially protected natural territories of Federal value in the total area of the subject of the Russian Federation” is recommended to be assigned all regions of Russia. Identification and elimination of objects of accumulated environmental damage that threat to the Volga river is relevant, at least for all the regions in which the Volga flows. Not all regions with a high level of air pollution and/or large masses of air pollutants have the indicator “reduction of total emissions for the reporting year”. It is necessary to increase the Program of measures for the protection of rare and endangered species of plants and to expand the list of regions in which it is planned to protect rare and endangered species of animals.

Quantitative assessment and evaluation of ecological parameters and biodiversity conservation are prime concerns for long-term conservation of rare and endangered species and their associated habitats in any ecological region. In this study, Gansu Province, a biodiversity hotspot, was chosen as the research area. We predicted the distribution patterns of suitable habitats for rare and endangered species. The replacement cost method was adopted to calculate the conservation value of rare and endangered species. The suitable habitat distribution area of rare and endangered wild animals reached 351,607.76 km2 (without overlapping area), while that of plants reached 72,988.12 km2 (without overlapping area). The conservation value of rare and endangered wildlife is US $1670.00 million. The high-value areas are mostly concentrated in the south and north of Gansu Province. The conservation value of rare and endangered wild plants is US $56,920.00 million. The high-value areas are mostly concentrated south of Gansu Province. The conservation value is US $58,590.00 million a year, and its distribution trend is gradually decreasing from northeast to southwest, with the highest in the forest area south of Gansu Province, followed by the Qilian Mountain area in the north. These results are of great significance for future improvement of the evaluation index system of ecosystem services and the development of ecosystem services and management strategies.

[The spring presence of two individuals of the Sea lamprey, Petromyzon marinus, in the River Mignone near Tarquinia (Northern Lazio) could highlight a new Italian reproductive site of this rare and endangered species. This exceptional possibility could certainly be favored by the good quality of both the waters of the Mignone, and the environmental context of the record, but would require the urgent equipment of the barrier of Le Mole with a fish ladder in order to allow the sea lamprey’s upstream migration towards the areas of the upper course, even more suitable for their reproduction].   [Article in Italian]
