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.

Rare And Endangered

Since 2007 staff at Limahuli Preserve have been developing practices to effectively reintroduce native plants into a highly degraded environment, creating a forest high in diversity and a safe habitat for some of the rarest plant species on the planet. Initial efforts were focused on the Limahuli Valley and limited progress was made because of the exposed conditions and prevalence of weed species. Relocation of the project to areas with tree cover has resulted in greater success. These successes have been built on to extend the project to the reintroduction of rare and endangered species. The methods used to transform a habitat where non-native and weed species dominate to one in which native, including endangered, species thrive is described. The value of staff with horticultural knowledge and experience of the habitat and climate is stated and ideas for the future of the habitat at Limahuli Preserve are given.

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.

Based on the long-term studies conducted in the Nakhchivan Autonomous Republic (2004-2017) and the literature data, the composition of Rosa L. genus was investigated and its distribution zones were specified. It has become clear that 34 species of hips are spread in the area that, 30 of them are wild, and 4 of them – R. centifolia L., R. chinensis Jacq, R. damascena Mill., R. multiflora Thunb. are used for greenery of parks and gardens in cultivated conditions. In recent years, as a result of the effects of climatic and anthropogenic factors on the territory of the autonomous republic, wild species of Rosa L. genus have been found to be in danger. Therefore, considering their rare and endangered species of Rosa karjaginii Sosn., R. nisami Sosn., R. sosnovskyana Tamamsch., R. rapinii Boiss. & Bal., R. pimpinellifolia L., R. tuschetica Boiss. have been put “Red book” of Nakhchivan Autonomous Republic, Rosa azerbaidzhanica Novopokr. et Rzazade, Rosa karyagini Sosn. və Rosa nisami Sosn. species have been put “Red Book” of Azerbaijan Republic and there have been shown protection ways.

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]
