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]

Orchids are perennial, epiphytic, terrestrial or lithophytic herbs with roots having multilayered spongy tissues. In Nepal, 363 species of orchids are organized into 97 genera. Orchids fall under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix II but do not fall under the legal protection of any existing national legislation. Habitat loss, forest destruction and degradation and over-exploitation have posed threats to the conservation of orchids in Nepal. The current study aims to document the orchids and estimate the stock of Dendrobium denudans and Dendrobium eriiflorum in a few potential locations of Rolpa district. A total of 36 species were documented in the surveyed 17 Village Development Committees (VDCs). Among them, 31 species were identified up to species level, two species up to generic level and the remaining three were unidentifed. The total stock of D. denudans was highest in Uwa VDC with 11018.08 kg followed by Seram VDC with the stock of 9982.57 kg. Similarly, D. eriiflorum stock in Seram, Siuri and Jaimakasala VDCs were 22750.01 kg, 7039.67 kg and 4933.46 kg, respectively. This study recommends a systematic research on the propagation technique; complete indexing of orchids; and inclusion of orchids in the Red Data Book on the threatened and endangered species. Orchid reserves in orchid hotspots should be established for the preservation and promotion of regeneration activities. The rare and endangered species should be preserved in botanic gardens. In addition to scientific attempts, the country should launch and implement a very firm regulation for their protection.
