Abstract

Background

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 In a standardised form, this article summarises both already published (mainly in Russian) and unpublished materials.

New information

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".

Introduction

The first data on the biodiversity of the Shichengskoe mire were obtained during short visits of scientists from the Vologda State Pedagogical University to study the lakes in the region back in 1972 and to investigate the territory in order to create a new protected area in the Vologda Region back in 1986; the materials of these works were published in a very condensed form (Vorobyev et al. 1981, Bobrovskiy et al. 1993). By the beginning of the 21st century, data on the biodiversity of Shichengskoe mire and surrounding area were very scarce (Vorobyev 2007, Philippov 2010).

In July-August 2000 and 2002, two field studies by Svetlana P. Bobrova with a group of secondary school students were carried out in Shichengskoe Lake, Polyanok Lake and Plakunovskoe Lake (Smirnov 2002, Evgrafova 2004).

Our studies of the Shichengskoe mire began in 2000 and continue to the present day. Between 2000 and 2003, field research was carried out by Dmitriy A. Philippov as part of his university graduate thesis supervised by Andrey N. Levashov. The graduate thesis entitled "Flora of the Shichengskiy Landscape Reserve and its analysis" contained data on 177 species of vascular plants. For several following years, the biodiversity studies of the Shichengskoe mire were fragmentary.

Since 2009, a purposeful collection of data on the composition and structure of various groups of living organisms in the Shichengskoe mire has begun. Mikhail V. Dulin took part in liverworts research in May 2009; vascular plants, fungi and lichens were investigated with the help of Victoria V. Yurchenko in early October 2009.

Significant impact to the studies of the Shichengskoe wetland occurred when the focus shifted to the hydrobiological studies of different types of intra-mire water objects (Philippov 2017). During vegetation seasons in 2012-2015, the primary attention was paid to zooplankton (Zaytseva et al. 2016, Zaytseva et al. 2017, Lobunicheva and Philippov 2017), zoobenthos (Ivicheva and Philippov 2013, Ivicheva and Philippov 2017), bacterio- and virioplankton (Stroynov and Philippov 2017a, Stroynov and Philippov 2017b) and phytoplankton. At that time, we summarised materials on vascular plants (Philippov 2015a, Bobroff et al. 2017), mosses (Philippov and Boychuk 2015), liverworts (Philippov and Dulin 2015) and birds (Philippov and Shabunov 2013) and studied plant-invertebrate interactions of Utricularia intermedia (Zaytseva et al. 2014). In July 2012, Sphagnum mosses were sampled to study the testate amoebae composition (Philippov and Leonov 2017). In 2013, samples of terrestrial chortobionts (insects and spiders) were collected (Pestov and Philippov 2016, Pestov and Philippov 2021). In 2013 and 2014, an investigation of Sphagnum mosses growth rate in the Shichengskoe mire was conducted (Bengtsson et al. 2021). In 2015, samples of microalgae (Sterlyagova et al. 2016) and protozoa (Prokina et al. 2016, Prokina et al. 2017, Prokina and Philippov 2018, Prokina 2020) were collected. In 2014, 2016 and 2019, materials on mites inhabiting in mire sites with Sphagnum mosses were gathered (Minor et al. 2016, Minor et al. 2019). In August 2019, September 2020 and June 2021, samples of peat soils for metagenomic studies of prokaryotic diversity were collected (Ivanova et al. 2020, Dedysh et al. 2021). In 2019-2021, with the help of Aleksandra S. Komarova, aquatic and semi-aquatic insects (mainly Coleoptera) were collected (Sazhnev et al. 2019b). Field studies of lichens, fungi, fish and terrestrial vertebrates were always incidental. The materials were partly published as new regional findings of rare, new or interesting species: mosses and liverworts (Afonina et al. 2010, Dulin and Philippov 2010, Abolin et al. 2011, Sofronova et al. 2013, Sofronova et al. 2015, Sofronova et al. 2018, Sofronova et al. 2019), vascular plants (Philippov 2015c), algae (Kapustin et al. 2016a, Kapustin et al. 2016b, Vishnyakov and Philippov 2018), lichens (Czhobadze and Philippov 2015), insects (Ivicheva and Philippov 2015, Philippov 2015b, Philippov 2015d, Prokin et al. 2016, Sazhnev and Philippov 2017, Sazhnev et al. 2017, Sazhnev et al. 2019a, Sazhnev et al. 2020) and birds (Philippov and Shabunov 2014, Philippov 2016, Shabunov and Philippov 2018, Shabunov et al. 2019).

It is worth noting that we also obtained data on the hydrochemical composition of water (Philippov 2014, Philippov and Yurchenko 2020), microclimatic conditions (Philippov and Yurchenko 2019), heavy metal contamination of the mire surface (Shevchenko et al. 2018) and mercury contamination of peat (Udodenko and Philippov 2017).

Thus, over the past two decades, a significant amount of multifaceted materials on the biodiversity of the Shichengskoe mire and its hydrographic network has been accumulated, which we summarised in a GBIF dataset (Philippov et al. 2021).

Biodiversity and conservation of mires of Nothern Russia

Personnel: 

Dmitriy A. Philippov

Sampling methods

Description: 

The list of occurrences of different taxonomic and ecological groups of organisms inhabiting a large wetland in north-western Russia, the Shichengskoe mire, is presented. At the time we started our studies, only fragmentary data on the biodiversity of the Shichengskoe mire had been obtained (dated 1972, 1986, 2000 and 2002). Our work began in 2000 and continues to this day. The most detailed and long-term biodiversity studies were carried out for higher plants and terrestrial and aquatic invertebrates. The data on the composition of lichens, protozoa, algae, basidiomycetes, some groups of invertebrates (e.g. Collembola), lichens and vertebrates are far more scarce and require further substantial research efforts. The dataset includes species observations made both within the peat bog (mire sites and mire margins differed in typology) and in the mire hydrographic network, which we consider a structural element integral to the mire ecosystem (Philippov 2017). This dataset includes both published and unpublished materials.

Sampling description: 

Biodiversity studies in the Shichengskoe mire were conducted from April to October, employing the route, reconnaissance and semi-stationary field approaches. Most microhabitats [a habitat which is of small or limited extent and which differs in character from some surrounding, more extensive habitat] were studied regularly during one or several vegetation seasons, but some were visited only once. The set of methods and techniques used in the field depended on both financial, time and logistical capabilities and the available specialists for specific taxonomic groups. We used a general approach to hydrobiological and ecological research of mires developed by the authors to study wetlands in Russia, described in the publication (Philippov et al. 2017).

Quality control: 

The data were collected and identified by scientists from Papanin Institute for Biology of Inland Waters Russian Academy of Sciences, Tyumen State University, Vologda Branch of the Russian Federal Research Institute of Fisheries and Oceanography, Vologda State University, Institute of Biology of Komi Science Centre of the Ural Branch of the Russian Academy of Sciences, Syktyvkar State University named after Pitirim Sorokin, Institute of Biology of Karelian Research Centre of the Russian Academy of Sciences and the Institute of Plant and Animal Ecology of the Ural Branch of the Russian Academy of Sciences. The accuracy of identification of some samples was confirmed by the experts from Timiryazev Institute of Plant Physiology of the Russian Academy of Sciences.

Step description: 

I. Research problem formulation.

II. Logistic issues resolution, including planning the location of routes, selection of water object, time and duration of work.

III. Field stage: obtaining samples and other original materials on the biodiversity of various components of the mire ecosystem.

(a) Macrophytes. In the field, pictures of plants and floristic lists were made, some species were collected in a herbarium (Philippov 2015a, Philippov and Boychuk 2015, Philippov and Dulin 2015, Bobroff et al. 2017); several hydrochemical parameters (water temperature, total dissolved solids, pH and electrical conductivity) were measured using portable devices. On the model sampling plots, relevés were made for mire sites different in microrelief (strings/ridges, hummocks, lawns, hollows, hollow-pools).

(b) Fungi. Basidiomycetes and lichens were studied on the way; as a rule, they were photographed and some samples were collected in the herbarium (Czhobadze and Philippov 2015).

(c) Algae. Samples were collected from the surface layer of water in several spots within the studied microhabitat using a plankton nylon net with a 20 μm pore diameter and a plastic sampler. Samples were fixed with 4% formalin (Kapustin et al. 2016b, Sterlyagova et al. 2016).

(d) Protozoa. Samples of heterotrophic flagellates and centrohelid heliozoans were collected in various microhabitats (water, upper peat or sediment layers, plants – by squeezing or washing off). Samples were collected in plastic tubes and transported to the laboratory at 4°C (Prokina et al. 2017, Prokina and Philippov 2018). To study testate amoebae diversity, Sphagnum mosses were collected in plastic tubes; the number of individual plants varied depending on different species growth densities (Philippov and Leonov 2017).

(e) Aquatic invertebrates. Zooplankton samples were collected at the model mire sites (lake, hollow-pool, fen strip, hollow and mire stream) by filtering water (5 to 50 litre) through a plankton net with 74 µm mesh. Samples were preserved with 4% formalin (Zaytseva et al. 2016, Zaytseva et al. 2017, Lobunicheva and Philippov 2017). Benthos invertebrates were collected at the model mire sites (lakes, fen strip and mire stream) with a bottom scraper (20 × 20 cm area). Each sample was washed through a 250 μm mesh nylon sieve, put in a plastic container and preserved in 40% formaldehyde. In mire streams and lakes, macrophyte-associated invertebrates were sampled; for that, water mosses clumps and aquatic plants with floating leaves were placed in plastic containers and preserved in 40% formaldehyde (Ivicheva and Philippov 2013, Ivicheva and Philippov 2017). The composition of aquatic, semi-aquatic and amphibiotic beetle communities was studied using trampling and sweeping procedures (Sazhnev and Philippov 2017, Sazhnev et al. 2019b, Sazhnev et al. 2020) and ethanol preservation of imagines and larvae.

(f) Terrestrial and soil invertebrates. The study of terrestrial insects and arachnids was carried out mainly on three model sites (fen strip, a ridge-hollow site and a mire stream valley at the mire margin) using a sweeping technique (30 sweeps in triplicate; diameter of the hoop 30 cm) ("Pollard walks") (Pestov and Philippov 2021). Manual collection of insects was performed outside the model sampling plots. Captured arthropods were euthanised with diethyl ether (Golub et al. 2021). Ticks were studied mainly in Sphagnum-dominated communities. Within the selected mire sites, samples were collected in microhabitats - on certain Sphagnum species from mire sites different in microrelief (ridge, carpet, hollow). Sphagnum moss samples for mite extraction were collected using a 10 × 10 cm frame to the depth of living moss plants (including capitula and the length of stems). Collected samples of moss substrates were placed in plastic zip bags and transported to the laboratory (Minor et al. 2016, Minor et al. 2019).

(g) Vertebrates. Along with studying other groups of organisms, visual observations of vertebrates and their traces were carried out (Philippov and Shabunov 2013). Whenever possible, animals and their traces were photographed, feathers or other fragments of animals or faeces were collected. Fishing was carried out with a float rod within legally-approved periods.

IV. Data collection: analysis of samples not identified in the field or verification of the identification data by the experts.

(a, b) Macrophytes and fungi. Herbarium materials of Tracheophyta, Bryophyta, Marchantiophyta and Ascomycota were transferred for processing to the Herbarium of the Mire Research Group of Papanin Institute for Biology of Inland Waters Russian Academy of Sciences (MIRE), while some doublets were transferred to VO, IBIW, PTZ and SYKO.

(c) Algae. Sedimented phytoplankton for qualitative and quantitative analysis was examined in a Nageotte counting chamber (0.01 cm3) using a ZeissAxiolab, NikonEclipse 80 i and XSZ-2101 (at 400x and 1000x magnification). Taxonomic identification was made to the closest possible low-range taxon.

(d) Protozoa. In the laboratory, heterotrophic flagellates and centrohelid heliozoans samples were enriched with a suspension of Pseudomonas fluorescens Migula bacteria at the ratio of 0.15 ml of suspension per 5 ml of sample and placed in Petri dishes. Samples were kept at 22°C in the dark and observed for 10 days to reveal the cryptic species diversity according to the accepted methodology (Vørs 1992). For observations, an AxioScope A1 light microscope (Carl Zeiss, Germany) with DIC and phase contrast and water immersion objectives (total magnification 1120x) was used. Video recording was made by an AVT HORN MC1009/S analogue video camera. Electron microscope preparations were carried out according to the approved method (Moestrup and Thomsen 1980) and observed in a JEM-1011 transmission electron microscope (Jeol, Japan). Testate amoebae samples were analysed immediately after transportation to the laboratory. NU-2E and Peraval-Interphako with water and oil immersion and an MBI-3 light microscope with a KF-5 phase-contrast installation in transmitted light were used. Analysis of heterotrophic flagellates, centrohelid heliozoans and testate amoebae abundance in the samples was not performed.

(e) Aquatic invertebrates. All specimens of zooplankton and zoobenthos were identified with an MBS-10 stereoscopic microscope and a Mikmed-6 microscope (LOMO, Russia). Aquatic insects were identified using Micromed MC-5-ZOOM LED and Leica M165C stereoscopic microscopes. These materials are deposited in the Papanin Institute for Biology of Inland Waters Russian Academy of Sciences (IBIW RAS): “Collection of autotrophic and heterotrophic organisms of mire ecosystems, IBIW RAS” and the entomologic collection.

(f) Terrestrial and soil invertebrates. On the day of sampling, sweep samples of terrestrial arthropods were primarily sorted by the main taxonomic groups (spiders, beetles, dipterans etc.). Separate samples were then fixed in ethanol. Detailed analysis, identification and counting were performed later by experts. Part of the collection was deposited in the Science Museum of the Institute of Biology of Komi Science Centre of the Ural Branch of the Russian Academy of Sciences. Mites from moss samples were extracted in modified Berlese funnels for five days. Adult Oribatida and Mesostigmata were identified to a species level and counted. Taxonomic identification of mites was carried out by the Acarology research group of Tyumen State University.

(g) Vertebrates. Found fragments of animals and their traces were collected and studied in the laboratory. Faunal lists were compiled.

Records list compilation. The dataset field names were chosen according to Darwin Core (Wieczorek et al. 2012). Georeferencing was made using a GPS navigator or Google maps. In all cases, the WGS-84 coordinate system is used.

Geographic coverage

Description: 

The study area is situated in the central part of the Vologda Region (59.8988 – 60.0590 N, 41.2327 – 41.5540 E), north-western Russia, the southern part of the middle taiga zone (Fig. 1). Shichengskoe wetland is a large mire area including the peat bog (Shichengskoe mire), intra-mire lakes (Shichengskoe Lake, Plakunovskoe Lake, Polyanok Lake) and rivers (Glukhaya Sondushka River, Sondushka River, Shichenga River), nameless mire streams and brooks, fen strips and lags, Sphagnum hollows, secondary hollow-pools and disturbed areas (Philippov 2017). Chemical characteristics of the intra-mire water objects were reported earlier (Philippov and Yurchenko 2020), as well as the data on microclimate differences between the mire sites (Philippov and Yurchenko 2019).

Figure 1.  

Location of the Vologda Region (top left), Shichengskoe mire (bottom left) and sampling sites (yellow circles on the right picture).

The study area is characterised by a temperate continental climate with long, cold, snowy winters, short springs with fluctuating temperatures, relatively short, moderately warm summers and long and rainy autumn. The average annual air temperature is + 1.5 to + 2.0ºC, the average monthly temperature in July is + 16 to + 17.0ºC, in January, -12.5 to -13.0ºC. The average annual precipitation ranges from 650 to 750 mm; during the active growing season, from 350 to 375 mm. The prevailing wind direction is southwest and south (Skupinova 2007).

The study area is confined to the Permian-Triassic plateau. The bedrock sedimentary rocks occur at a depth of 20–40 m and are represented by limestones and clays with lenses of sandy loam of the Tatar stage of the Permian system. The main features of the relief of the region are determined by glacial accumulation in the terminal moraines formed during the Moscow glaciation. Shichengskoe wetland was formed mainly by the limnogenic process on the south-eastern spurs of the Kharovsk ridge in a vast lacustrine-glacial basin. The ancient lake basin is orientated from northwest to southeast and reaches 20–25 km across. The bottom of the basin is a typical lacustrine-glacial plain with absolute heights of 130–150 m above sea level (Savinov and Romanova 1970). At the beginning of the Holocene, the post-glacial lake was significantly drained by rivers and streams, overgrowth and peat accumulation followed and a peat bog began to form in its place. Currently, a large mire with a residual lake fill up the Shichengskiy ancient lake basin.

The main aquifers are lacustrine, lacustrine-glacial and fluvioglacial intermoraine Quaternary sediments confined to sands, less often to interlayers of sands in sandy loams and clays. The area is provided with low-mineralised groundwater (Savinov and Filenko 1970). The surface waters of the Shichengskoe wetland belong to the regional drainage basin of Kubenskoe Lake, the global drainage basin of the Arctic Ocean (White Sea).

The soil-forming rocks in the area are moraines, enriched with boulders, sometimes carbonate material, less often fluvioglacial and binomial deposits being the parent rocks in the study area (Komissarov 1987). Directly on the territory of the Shichengskoe mire, soils are predominantly hydromorphic and semi-hydromorphic and peat soils prevail over the occupied area.

According to geobotanical zoning (Abramova and Kozlova 1970), the Shichengskoe wetland is located in the southern part of the Verknevazhsko-Kuloiskiy geobotanical district of haircap-moss and berry-grass spruce forests, pine and birch forests, transitional mires and raised bogs. In the region, almost half of the forest formations grow on soils of varying degrees of waterlogging due to insufficient drainage of the prevailing moraine and lacustrine-glacial plains composed of loams. About 80% of the forested area is occupied by pine forests with low quality of locality and represented mainly by swamp forest coenoses. About 10% of the forested area is occupied by spruce forests, of which paludified types prevail. Small-leaved forests are mainly represented by birch forests, which formed mainly at clearings (Bobrovskiy et al. 1993).

According to the classification proposed by T.K. Yurkovskaya (Sirin et al. 2017), Shichengskoe mire belongs to Pechora-Onezhskii raised bog type of the North-Eastern European Sphagnum raised bogs group of Sphagnum mires. Currently, the main part of the mire is at the oligotrophic stage of development; however, there are areas of eutrophic and mesotrophic types of water-mineral nutrition. The mire is located on the territory of the Shichengsko-Kuloiskiy mire district (Abramova 1965), which is paludified by more than 19% (Filonenko and Philippov 2013) and characterised by the predominance of forested mesotrophic and oligotrophic mires of lacustrine origin.

Since 1987, about 90% of the Shichengskoe wetland has belonged to the regional Shichengskiy Landscape Reserve. This Reserve is the largest landscape reserve in the Vologda Region (136.1 km2).

Additional information

The studied biotopes of the Shichengskoe mire were placed in the following groups:

(1) Mire expanse lake with its coastal area; this group combines Shichengskoe Lake, a 10.2 km2 flow-through shallow primary lake centrally situated in a mire expanse and the Lake’s paludified coastal area formed mainly by raised bog sites.

(2) Non-central mire lakes with coastal areas; this group includes two small lakes, Polyanok Lake and Plakunovskoe Lake, about 0.04 km2 each, non-flow-through 6-7 m deep primary lakes located closer to the edge of the Shichengskoe mire and lakes’ paludified coastal areas formed mainly by rich fen mire sites.

(3) Floating mats; this group includes peat-forming vegetation held together by roots and rhizomes and floating on water, developing in lakes and mire rivers.

(4) Mire rivers with banks; this group includes three small, 5 to 50 km long, rivers with river banks: Sondushka River and Glukhaya Sondushka River, draining into Shichengskoe Lake and Shichenga River, the outlet of Shichengskoe Lake.

(5) Mire streams with valleys; this group includes small watercourses with the weak flow, their paludified banks and weakly pronounced forested eutrophic valleys.

(6) Fen strip sites; this group includes structural elements of fen strips, specific water objects forming solely in mires, narrow mire areas receiving an inflow of water from the surrounding mire, almost without trees, with meso- or meso-oligotrophic with grass and grass-moss communities. In the Shichengskoe mire, these flow-through fen strips begin at the intra-mire islands.

(7) Rich fen sites; this group includes rich fens, peatlands receiving an inflow of water from the mineral soil, located closer to the mire’s edge, having groundwater outlets and eutrophic peat.

(8) Raised bog feature and its elements; this group includes ridges, hummocks, lawns, Sphagnum hollows and secondary hollow-pools, the structural elements of oligotrophic mire sites (that occupy the most significant area in the Shichengskoe mirе), underlain by oligotrophic peat and having a set of plant communities characteristic of the taiga zone. Often these structural elements in various combinations form patterns, for example, a ridge-hollow pattern.

(9) Margins and edges; this group includes margins of a mire massif and paludified edges of intra-mire mineral islands.

(10) Disturbed areas; this group includes burnt places and bonfires, fishing grounds, trails and roads in a mire.

(11) Other biotopes; this group includes biotopes that did not fall into any of the previous groups and the occurrences of migratory birds and some mammals that pass through the mire or use several biotopes.

Examples of these biotopes are given in figures (Figs 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14).

The studied biotobe groups were investigated unevenly (Table 1). A strong correlation was found between the number of occurrences and the number of lower-rank taxa found in the groups of biotopes (Spearman Rank Correlation Coefficient 0.98, p < 0.05). The greatest number of occurrences came from the raised bog features and their elements and fen strip sites which accounted for 359 and 371 lower-rank taxa, respectively. Mire streams with their valleys and margins and edges were studied much less, but these biotopes also showed significant biodiversity.

Half of the total occurrences came from the intra-mire water bodies that comprised 59.6% of lower-rank taxa (Table 2). The most studied were fen strips and this biotope group showed the most significant biodiversity. It is worth noting that the second largest number of lower-rank taxa was found in Shichengskoe Lake, the mire expanse lake, the largest in the studied mire complex; it provided one-third of the lower-rank taxa, based on almost one-eighth of the number of occurrences.

During the studies, we found a significant amount of endangered species within the Shichengskoe wetland, five included in the Red Data Book of the Russian Federation (Danilov-Danilyan 2001, Bardunov and Novikov 2008): a stonewort Chara strigosa, a hawker dragonfly Anax imperator, a raptor Pandion haliaetus, a wader Numenius arquata and a songbird Lanius excurbitor. Notably, the first two species have not been included in the Red Data Book of the Vologda Region because no confirmed findings had been known in the region at the time. In the Red Data Book of the Vologda Region, 57 species found in the Shichengskoe wetland are listed (Bolotova et al. 2010, Suslova et al. 2013, Anonymous 2015). According to the IUCN status, Critically Endangered (CR) – Saxifraga hirculus; Endangered (EN): Hammarbya paludosa; Vulnerable (VU): Sphagnum lindbergii, Cygnus cygnus, Lagopus lagopus, and Limosa limosa; Near Threatened (NT): Drosera anglica, Utricularia minor, Dactylorhiza baltica, Trichophorum alpinum [as Baeothryon alpinum (L.) Egor.], Carex oederi var. oederi [as C. serotina Merat.], Rhynchospora alba, Grus grus, and Numenius phaeopus; Least Concern (LC): Ligularia sibirica, Petasites frigidus, Malaxis monophyllos, Carex pseudocyperus, Papilio machaon, and Milvus migrans; Data Deficient (DD): Oxycoccus microcarpus, Cladonia stygia and Ramalina dilacerata. Amongst the 57 species listed in the Red Data Book of the Vologda Region, there are 35 rare species marked as biological control required: Nymphaea candida, Rumex hydrolapathum, Betula humilis, Betula intermedia, Moneses uniflora, Empetrum hermaphroditum, Salix ×holosericea [as S. dasyclados Wimm.], Salix lapponum, Daphne mezereum, Rubus arcticus, Galium triflorum, Utricularia intermedia, Dactylorhiza fuchsii, Dactylorhiza incarnata, Dactylorhiza russowii, Epipactis palustris, Gymnadenia conopsea, Platanthera bifolia, Scolochloa festucacea, Hydrocharis morsus-ranae, Potamogeton berchtoldii, Potamogeton praelongus, Sparganium natans, Typha angustifolia, Sphagnum subsecundum, Sphagnum wulfianum, Meesia longiseta, Scapania paludicola, Icmadophila ericetorum, Gammarus pulex, Colias palaeno, Bombus jonellus, Ardea cinerea and Lutra lutra. However, only 80% of the total number of rare and protected species was registered within the boundaries of the Shichengskiy Landscape Reserve.
