The ancient fortified settlement of Amnya I is a unique Early Neolithic site in the northern taiga zone of Western Siberia (Khanty-Mansi Autonomous Okrug, the Amnya river). It is located on a promontory and has three lines of defense and ten dwelling depressions. The structures of the excavated dwellings are very similar, though the artifact assemblage appears rather heterogeneous. We carried out a technical and technological analysis of ceramics, which showed no correlation between the texture, on the one hand, and the morphology and ornamentation of pots on the other one. Planiographic analysis of ceramics showed that vessels with comb and incising patterns are found in different dwellings, although there are objects in which both groups lie together. Various categories of stone implements (bladelets and polished arrowheads) also appear on different parts of the settlement. Most likely, the observed differences in the artefact complexes of objects are associated with the stages of the functioning of the settlement. The absolute chronology does not yet clarify the sequence of erection and existence of objects. New AMS date is probably vulnerable to a significant reservoir effect. The abundance of unsolved issues of absolute and relative chronology makes the resumption of research on this unique site urgent.

The Onega Peninsula is located in the north-west of Russia in the Arkhangelsk Region, juts out into the White Sea, is located in an area of a transitional climate from an oceanic to a continental temperate climatic zone, belongs to the central sector of the northern taiga zone. The flora and fauna of the peninsula are very diverse. A significant part of natural complexes is highly preserved and is ideal for biosphere monitoring. In connection with intensive industrial logging on the peninsula, there is a need to identify rare species of living organisms and determine measures for their protection. The article provides data on the finds of habitats of 11 rare species discovered by the author during field routes along the Lyamitsky landscape in the period from 2009 to 2020. Finds of 10 out of 11 species have not been previously published. In 2020, the state of a group of individuals of 1 of 11 species that had not yet formed a stable population was reexamined, the find of which was previously published. This species (derbyanka spikate) is new for the Arkhangelsk and all adjacent regions and needs to be entered into the Red Book of the Arkhangelsk Region, which includes the remaining 10 species. 4 species of them are also included in the Red Book of the Russian Federation. The finds of the species belong to the lands of different purposes: to the forbidden zone of forests and to the lands of the forest fund leased by a logging company. The article discusses the number of discovered species and such a limiting factor as logging. The assessment of the feasibility of measures for the protection of species has been carried out. It was revealed that some of them (splachnums) increase in number due to felling, the number of others is not threatened by felling (common viper, etc.), to preserve the number of the third, special protection measures are required (pulmonary lobaria, truncated horn, etc.). The information obtained is processed cartographically using geoinformation technologies and can be used to replenish the database of the Red Book species and to organize their protection.

Results of a syntaxonomical study of the oligotrophic forests of northern European Russia are presented. The main forest types have been classified into 2 orders of the class Vaccinio-Piceetea, 4 alliances, 6 associations and 1 community. The new alliance Empetro-Piceion all. nov., which includes zonal spruce and birch northern forest association Empetro-Piceetum, has been established. These communities are formed according to cold temperature and high (sometimes temporarily) soil moisture and are characterized by the lower tree canopy, mosaic herb and moss-lichen layers with boreal mosses, sphagnum and lichens. In the middle taiga subzone these communities are replaced by Eu-Piceetum myrtilletosum. The forests with lichens are referred to order Cladonio-Vaccinietalia and divided into 4 associations. Lichen pine forests of the north-west of boreal zone were described as ass. Flavocetrario nivalis—Pinetum ass. nov. This association with a great number of lichens is differentiated by Cladonia arbuscula subsp. mitis, Flavocetraria nivalis, Cetraria ericetorum, Stereocaulon grande, Dicranum fuscescens, D. drummondii, Nephroma arcticum and species of Cladonia. The ass. Cadonio arbusculae—Pinetum (Caj. 1921) K.-Lund 1967 contains lichen pine forests with lower number of lichens and is distributed mostly in middle part of the taiga zone. The spruce-pine forests with mixed moss-lichen cover correspond to ass. Vaccinio-Pinetum. Ass. Hedysaro-Laricetum represents rich and well differentiated larch forests in the east of European Russia.
