The Kurgalsky Nature Complex Reserve is located in the Kingisepp District of the Leningrad Region, 45 km northwest of Kingisepp. The territory of the reserve includes the Kurgalsky peninsula, as well as the adjacent waters of the Gulf of Finland. The Kader swamp massif is located in the south of the Kurgalsky Peninsula. The state of the autochthonous vegetation cover of the Kader swamp was considered in connection with the laying of the main gas pipeline under «the Nord Stream–2» project. The revealed high diversity of desmids (48 species), as well as their abundance, the frequency of occurrence and the presence of species rare in other habitats of the Leningrad region, indicates the inviolability of the freshwater algae flora, favorable environmental conditions in water bodies and the absence of anthropogenic transformation of the studied territory.

The Gulf Of Finland

Biogenic pollution of water bodies and their eutrophication is one of the most serious environmental problems of our time. One of the sources of water pollution with biogenic substances is forests, which belong to the background sources of biogenic load. Currently available methods for assessing the removal of nutrients from the forest vegetation cover do not provide the desired results, which causes an urgent need for their improvement. This article describes the method developed by the authors of geoinformation modeling of removal of biogenic substances from the forest vegetation cover to water bodies, taking into account the spatial distribution of vegetation in the catchment area, its species composition and absorption of biogenic substances during their migration. The Eastern part of the Gulf of Finland was adopted as the object of testing of the developed method. this is due to the fact that eutrophication processes are actively manifested within its water area. The volume of the background biogenic load on the Gulf of Finland, formed during the decomposition of the fall of the natural vegetation cover in the catchment area, was determined based on the specific removal of biogenic substances from plant communities and their absorption during migration “plant community — water object”. The total background biogenic load on the eastern part of the Gulf of Finland, formed as a result of decomposition of natural vegetation cover, was 170.21 t/year for the northern catchment for nitrogen, 12.14 t/year for phosphorus, and 207.31 t/year for the southern catchment for nitrogen , and 15.68 t/year for phosphorus. The data obtained do not contradict the results of other authors who study the background biogenic load on the Gulf of Finland. The method can be effectively used in the development of measures to reduce the nutrient load on water bodies and planning of economic activities in catchments.

A lichen checklist for Maly Island (Leningrad Region, Russia) comprises 160 species, including 150 lichens, 9 lichenicolous fungi and 1 non-lichenized saprobic fungus. Lecidella effugiens is new to North-Western European Russia, Diplotomma pharcidium and Taeniolella delicata are new to the Leningrad Region. The lichen biota of Maly Island is relatively poor due to natural and anthropogenic factors: the island is small, sandy, lacking rocky outcrops, with low diversity of plant communities; all its forests are disturbed and young. The most valuable habitats for lichens on Maly Island are seashore communities and open pine stands on sand.

Forty six species of lichens and allied fungi are firstly reported for protected areas of the Gulf of Finland Shore within the limits of St. Petersburg. Three of them (Calicium denigratum, Lecanora expallens and Pertusaria pupillaris) are new for St. Petersburg. One species — Verrucaria bryoctona — is new for the whole Leningrad Region.

Significance The unilateral move is raising concerns in Europe that EU energy companies could be sanctioned and that transatlantic unity on sanctions could be jeopardised. Impacts The bill could cause a further deterioration in US-Russian ties and weaken Trump’s ability to improve relations with Moscow. Less EU-US coordination on sanctions could bring internal EU divisions to the fore. Apart from Nord Stream 2, the sanctions could also affect the Blue Stream pipeline and a liquified natural gas plant in the Gulf of Finland.

The Gulf of Finland has during the last centuries been loaded with heavy metals of anthropogenic origin. Work with mapping of the chemistry of the sediments have been done in all surrounding countries during several decades, first in the Soviet Union and later in Russia and similarly in Finland. More recent sediment chemistry data from the last two decades was in this study combined into sediment chemistry maps added with some data from the commercial Nord Stream project. The result shows that zinc, copper and chromium are enriched in the eastern part of the Gulf of Finland, while mercury, cadmium and lead are showing the highest concentrations in the north- eastern part of the gulf.

We present a lichen checklist for the northern shore of the Gulf of Finland in the limits of St. Petersburg, Russia. This area has diverse lichen biota within the city limits, and has been comprehensively studied since 1893, which gives a good base for analysis of historical changes in lichen diversity. The documented lichen biota comprises 469 species (430 lichenized, 24 lichenicolous, 3 facultatively lichenicolous, and 12 non-lichenized saprobic fungi), of them 191 species are known from herbaria and literature for the period before 1991, and 436 species were recorded since 1991 to 2019. Thirty-three taxa were excluded from the lichen list of the study area as erroneous or dubious records. Altogether 48 species are new to St. Petersburg, including: Lecidea malmeana and Micarea czarnotae – new to Russia; Caloplaca lucifuga, Gyalecta nigricans, Micarea soralifera – new to European Russia; Agonimia flabelliformis, Endococcus verrucosus, Lecania turicensis, Micarea fallax, M. tomentosa, Xanthomendoza huculica – new to Northwestern European Russia; Lichenoconium lichenicola, Ramalina europaea, Sarcogyne hypophaea – not known also from the Leningrad Region. The studied lichen biota is moderately rich compared to other city territories. The history of economic development of the region has caused its serious transformation, degradation of natural habitats and therefore partial loss of lichen diversity. At the same time, human-made substrates and anthropogenic plant communities are inhabited by lichens, including species unknown in the natural habitats of the study area. However, 44 species recorded in the study area are red-listed in St. Petersburg, with 13 of them known only from historical collections. Forest communities, as well as historical parks, in NW part of St. Petersburg are important source of biodiversity on regional level nowadays and hopefully in future, and deserve protection.
