Vascular plants and bryophytes of the natural monument «Petrovskoe boloto» (Russia, Bryansk Region): the preliminary lists

According to the results of the study of the flora of the natural monument of regional natural monument «Pe-trovskoe swamp» (Russia, Bryansk Region, Mglinsky district), carried out in 2018–2019, annotated lists of vas-cular plants and bryophytes were compiled. The flora of vascular plants includes 367 species from 80 families. The largest number of species is found in the families Asteraceae (40 species), Poaceae (34), Rosaceae (25), Fabaceae (19), Cyperaceae, Lamiaceae and Apiaceae (17), Caryophyllaceae (13), Ranunculaceae (15), Brassi-caceae and Scrophylariaceae (10). 5 of these species are listed in the regional Red Data Book (Krasnaia..., 2016): Diphasiastrum complanatum, Juniperus communis, Lathyrus pisiformis, Pulsatilla patens, Sanicula europaea. Alien species were recorded, including those spreading from cultivated coenoses in nearby settlements: Acer negundo, Amelanchier spicata, Echinocystis lobata, Helianthus tuberosus, Hemerocallis fulva, Hesperis pycnotricha, Levisticum officinalis, Oxalis stricta, Rudbeckia laciniata, Saponaria officinali, Sorbaria sorbifolia. Bryophytes belong to 107 species in 41 families. New localities of mosses listed in the regional Red Data Book were discovered: Homalia trichomanoides, Neckera pennata, Sphagnum jensenii. Indicator species of old-growth forests were noted: Anomodon longifolius, Homalia trichomanoides, Hypnum cupressiforme, Neckera pennata, Stereodon pallescens.

Protection of Rare Plant Species during the Development of Oil Fields in the South of Western Siberia (Tyumen Region, Russia)

The article provides a description of the vegetation and information on the discovery of plant species subject to protection, as revealed during the examination of the territory of licensed oil production sites located in the Uvatsky district of the Tyumen region (Western Siberia). The vegetation cover of the territory is represented by a combination of plots of dark-coniferous grass-shrub-green-moss forests, derivative communities in their place, pine-shrub-sphagnum marshes and floodplain meadow-shrub vegetation. The localities of 7 rare species subject to protection at the state and regional levels were discovered, including 2 species of lycopods (Isoetes lacustris, I. echinospora), 2 species of ferns (Dryopteris filix-mas, Phegopteris connectilis), 1 species of angiosperms (Nuphar pumila), mosses (Neckera pennata) and lichens (Lobaria pulmonaria). To preserve the discovered habitats of protected species, the necessary changes were made to the layout of the oil production facilities.

Diversity and distribution of epiphytic lichens and bryophytes on aspen (Populus tremula) in the middle boreal forests of Republic of Karelia (Russia)

The distribution of epiphytic bryophyte and lichen species growing on aspen in the middle boreal forests was studied in southern Karelia (Russia). These forests varied in time-since-disturbance from 80 to 450 years. Two hundred twenty two species of epiphytes, including 178 lichens, 32 mosses and 12 liverworts, were recorded on 192 aspen trees in forests over 24 ha, in the Karelian part of the Vodlozero National Park, Kivach Strict Nature Reserve, Kizhi Sanctuary and Petrozavodsk City. Arthonia biatoricola, A. excipienda and Biatoridium monasteriense were collected in Karelia for the first time. Eighteen rare species (lichens Anaptychia ciliaris, Arthonia vinosa, Bryoria nadvornikiana, Chaenotheca gracilenta, C. stemonea, Lecidea albofuscescens, Lobaria pulmonaria, Melanelixia subaurifera, Nephroma bellum, N. laevigatum, Phaeocalicium populneum, Ramalina thrausta, Rostania occultata, Scytinium subtile, Usnea barbata, mosses Neckera pennata, Plagiomnium drummondii and liverwort Lejeunea cavifolia) listed in the Red Data Book of Republic of Karelia (2007) were found. Relationships between epiphytic lichen and bryophyte species richness and certain environmental variables (at different trunk heights above ground and time-since-disturbance) were evaluated. Lichens and mosses on aspen trunks often occupy different ecological niches. Cover and diversity of bryophytes was high on trunk bases, while the number of lichen species and their cover were higher at a height of 1.3 m above ground level. The total number of lichen species on aspen increased on average from 40 to 60 species per ha with increasing time-since-disturbance from 100 to 450 years. A stabilization in lichen species number was observed at about 200 years since disturbance. No significant correlation was determined between bryophyte diversity on aspens and the time-since-disturbance.

Moss flora of the planned national park “Tulos” (Republic of Karelia)

Mosses of the planned national park “Tulos” were studied in 1997, 2004–2006. In total 150 moss species and 1 variety were recorded. Comments on ecology and distribution of all the species, and label data for rare mosses are given. Sixty six moss species and 1 variety are recorded as new to the planned national park “Tulos”, and 11 species as new to Kuitozero-Leksozero floristic district. Three species (Neckera pennata, Pseudotaxiphyllum elegans and Sphagnum auriculatum) are listed in the Red Data Book of Karelian Republic, and 4 species (Neckera pennata, Polytrichastrum pallidisetum, Sphagnum subnitens, S. inundatum) are in the Red Data Book of Finland.
