Muchnik, E.E./ Konoreva, L.A./ Kazakova, M.V./ Sobolev, N.A. 2018: The lichen biota of the Meshchera National Park (Vladimir Region, Russia) and Meshchersky National Park (Ryazan Region, Russia). - Nature Conservation Research 4(1): 64-82. [RLL List # 269 / Rec.# 43596]
Abstract: The article presents the results of lichenological studies at the territories of Meshchersky National Park (Klepiky district and Ryazan district of the Ryazan Region, Russia) and Meshchera National Park (Gus-Khrustalny district of the Vladimir Region, Russia). Both Protected Areas represent an entire natural-anthropogenic area created in 1992 to preserve the unique forests and wetlands of the Meshchera Lowland, and to restore forest-marsh territories damaged by draining and long-term extraction of peat. Both the national parks are located in the centre of the Meshchera Lowland, in the basin of the River Pra (left-side tributary of the River Oka), and its tributaries – the River Buzha and the River Pol. In 2008–2018, we studied the lichen diversity using the traditional route method with more detailed studies within 64 sample plots. The following habitat types were inspected: pine forests, mixed forests and small-leaved forests, floodplain oak forest, swamps, meadows and heaths, shores of water bodies, and anthropogenic biotopes. Material of previous studies was also included in the analysis. An annotated list included 199 lichen species and eight non-lichenised fungus-related species which are traditionally counted in lichen lists. They belong to 88 genera and 43 families. The similarity of the lichen lists of the two national parks is 0.63 according to the Sørensen-Dice index. Cladonia bacilliformis, Lecania naegelii, Peltigera polydactylon, Porpidia crustulata, Pycnora praestabilis, and Xylopsora caradocensis were new species for the Vladimir region. Cladonia bacilliformis, C. cervicornis, C. floerkeana, and Stictis mollis were new species for the Ryazan region. Cetraria ericetorum, Cladonia bacilliformis, C. cervicornis, C. floerkeana, Peltigera extenuata, Stictis mollis were new species for the Meshchersky National Park. Chaenotheca furfuracea, Cladonia bacilliformis, Lecania naegelii, Peltigera polydactylon, Porpidia crustulata, Pycnora praestabilis, Xylopsora caradocensis were new for the Meshchera National Park. Acrocordia gemmata, Bacidia rubella, Chaenotheca stemonea, Chaenothecopsis pusiola, and Cladonia parasitica were considered as indicators of old-growth and undisturbed forests. Four rare species (Bryoria fuscescens, B. nadvornikiana, Cetraria ericetorum, and Peltigera extenuata) are listed in the Red Data Book of the Ryazan region. The following 19 species are rare for the centre of European Russia: Absconditella delutula, Acarospora versicolor, Arthonia fusca, Bacidia friesii, Biatora albohyalina, Cladonia sulphurina, Lecania suavis, Lecanora fuscescens, Micarea erratica, Microcalicium ahlneri, Ochrolechia androgyna, Porpidia soredizodes, Rhizocarpon reductum, Stictis mollis, Thelocarpon laureri, Thelloma ocellatum, Toninia athallina, Trapelia placodioides, and Xanthoparmelia stenophylla. In total, the species richness of lichen biotas in both national parks is equivalent to that in the Oka State Nature Reserve (208 species).
