The paper is based on the dataset whose purpose was to deliver, in the form of GBIF-mediated data, diverse materials on the biodiversity of a large mire, Shichengskoe mire (Vologda Region, north-western Russia), including its various mire sites and intra-mire water bodies. The dataset was based on our materials collected for two decades (from 2000 to 2021) in different parts and biotopes of the Shichengskoe mire and complemented by scarce data obtained previously by other researchers. The data contain materials on the diversity of Animalia (2886 occurrences), Bacteria (22), Chromista (256), Fungi (111), Plantae (2463) and Protozoa (131). Within the study period, the most detailed and long-term biodiversity studies were carried out for higher plants and invertebrates. On the other hand, the data on the composition of lichens, protozoa, algae, basidiomycetes, some groups of invertebrates and, to a lesser extent, lichens and vertebrates are far less comprehensive and require further substantial research efforts. The list includes occurrences from both the peatland (mire sites and mire margins different in typology) and the objects of the mire hydrographic network. In a standardised form, this article summarises both already published (mainly in Russian) and unpublished materials. The paper summarises the results of long-term research on the biodiversity of a boreal mire, including its hydrographic network. A total of 5869 occurrences were included in the dataset published in the Global Biodiversity Information Facility (GBIF, gbif.org) for the first time. According to the GBIF taxonomic backbone, the dataset covers 1358 taxa, including 1250 lower-rank taxa (species, subspecies, varieties, forms) and 108 taxa identified to the genus level. Several species found in the Shichengskoe mire, mainly belonging to Bacteria, Chromista and Protozoa, have never been listed in GBIF for the territory of Russia before. The overwhelming majority of occurrences and identified species came from the territory of Shichengskiy Landscape Reserve. Due to our work, this Reserve is now the most studied regional reserve in the Vologda Region with respect to biodiversity. By the number of revealed species, it is close to two federal protected areas: Darwinskiy State Nature Biospheric Reserve and National Park "Russkiy Sever".
The article presents an analysis of chorologic, biomorphologic, phytocoenotic and ecological features of rare relict aquatic macrophyte species Lobelia dortmanna L. in the Vologda Region. For the first time on the territory of the Vologda Region Lobelia specimen was collected in 1884 by V. S. Sulima-Samuyllo. Southeastern border of areal of water lobelia passes through the Vologda Region where it was found in Babaevskiy (10 lakes), Belozerskiy (3) and Vytegorskiy (4) districts. Lobelia dortmanna is included in Red Data Book of the Vologda Region in the status 2/EN (Endangered). The major part of the records (11 out of 17 lakes) are out of protected areas. Lobelia dortmanna is under protection in 5 protected areas: Botanical nature sanctuaries “Chyornoe ozero” and “Kodozero” (Babaevskiy district), protected nature complex “Onezhskiy”, landscape reserve “Yansorskiy”, hydrological reserve “Shimozerskiy” (Vytegorskiy district).

The article presents data on the distribution, biomorphology, ecological and phytocenotic features of Blysmus compressus in the Vologda Region, as well as issues of the species conservation. The choice of this species as a research object was determined by its rarity in the region and its indicator properties of the presence of pressurized groundwater outlets. Analysis of herbarium collections, archived and published data showed that from 1856 to 2020, B. compressus was recorded in 65 localities within 20 (out of 26) administrative districts and was confined mainly to the valleys of large rivers. Species records fall within the boundaries of 30 squares of the grid system adopted in the Atlas Florae Europaeae. As a result of a detailed biomorphological analysis of the species, its life form was determined as a secondary rhizome non-turfy perennial polycarpic herb with an iterative growth of the shoot axis. This type of biomorph, in its structural basis, is characteristic of the whole Cyperaceae family and the iteration seems to correspond to the ecological conditions of the ecotope. B. compressus prefers lowland (wet and often paludified) meadows, eutrophic (most often, spring) mires, banks of water bodies and watercourses. The habitats of the broad blysmus are always associated with pressurized groundwater outlets and, as a rule, rich in carbonates. B. compressus is a hemi-eurybiontic species. The species realizes its ecological potential with reasonable efficiency (Zhukova's coefficient for most of the traits was not lesser than 0.5), although, judging by the entire complex of traits, in none of the studied ecotopes is was in optimal conditions. B. compressus is listed in the Red Data Book of the Vologda Region by the 3/LC category. It was recorded within the boundaries of only four specially protected natural areas. The necessary protection measures include the organization of new nature reserves at the sites where B. compressus is found, population monitoring, and searching for new places of its occurrence.
The work is devoted to the analysis of the flora of vascular plants in the valleys of the Kema and Unzha Rivers (the Volga basin), as one of the areas of the Vologda Region lacking botanical studies. In July 2005, the area from Borok of Nikolskiy District to Kunozh of Babushkinskiy District, with a total length of about 130 km, was surveyed using the route-key method. On this area, in the valley-river complexes, 454 species of higher vascular plants belonging to 255 genera and 84 families were recorded, including 371 species in the Kema River valley and 388 species in the Unzha River valley. The article contains an annotated list of flora; for rare and attention-grabbing species, complete label data are provided. The studied flora has a typical boreal character with significant participation of southern (nemoral, nemoral-boreal) and Siberian species. In the valleys of these rivers, a total of 70 species included in the second edition of the Red Data Book of Vologda Region have been identified. These species (listed according to their conservation status) were as follows: Endangered (EN): Epipogium aphyllum; Vulnerable (VU): Carex atherodes, Cinna latifolia; Near Threatened (NT): Brachypodium pinnatum, Cacalia hastata, Cenolophium denudatum, Chimaphila umbellata, Cotoneaster melanocarpus, Dactylorhiza baltica, Diplazium sibiricum, Glyceria lithuanica, Lathyrus pisiformis, Pyrola chlorantha, Stellaria hebecalyx, Viola collina, V. hirta; Least Concern (LC): Abies sibirica, Carex rhizina, Conioselinum tataricum, Dactylorhiza traunsteineri s.str., Delphinium elatum s.str., Goodyera repens, Huperzia selago, Ligularia sibirica, Malaxis monophyllos, Ophioglossum vulgatum, Trisetum sibiricum, Ulmus glabra, U. laevis; Data Deficient (DD): Campanula cervicaria, Rubus caesius, and also 39 species of “biological control” category. The paper presents data on the flora of “Gladkiy Bor” and “Unzhenskiy Les” landscape reserves. Within the boundaries of these specially protected natural areas, populations of 53 species officially recognised as rare species in the Region were identified (10 protected species and 15 species of biological control in “Gladkiy Bor” and 19 and 24, respectively, in “Unzhenskiy Les” landscape reserve).
