Sacred groves are the fairly well-protected system of community-based conservation of tree patches on account of their association with village gods, and repository of many rare and threatened elements of biodiversity. There are, however, few publications on lichens of sacred groves. The lichens have long been regarded as sensitive indicators for monitoring environmental state. The present study reports one hundred and sixteen species of lichens from forty-four genera of nineteen families in four selected sacred groves of Paschim Medinipur district, West Bengal. These lichens represent two different growth forms, i.e. crustose (105 species) and foliose (11 species). Shorea robusta, a dominant tree species in two sacred groves bears the highest lichen diversity with seventy-four species. To better understand the related biodiversity and climate, this work is likely to promote further studies on lichen diversity in other regions of West Bengal.

Old artificial parks are an important component of the cultural heritage in Southern Ukraine which represents a significant variety of specific habitats for lichen diversity. The aim of our research was to analyze the total lichen diversity in parks as well as the representation of rare and protected species. Most of the data were collected by the authors during expeditions in Southern Ukraine during 2017–2020 in Kherson and Mykolaiv regions. Overall, we identified 108 lichen species and 21 lichenicolous fungi within 17 old parks. The highest lichen diversity was recorded in parks “Labirynt” (66 species) and “Nedogirskyi Forest” (61 species). We found 18 lichen species (16.6 %) included in the Red List of Kherson and Mykolaiv regions and 25 (23.8%) rare forest-dwelling species. We concluded that old artificial parks are very important habitats for lichen diversity in the steppe zone of Ukraine as well as the unique localities for such species as Graphis scripta, Hyperphyscia adglutinata, Sclerophora pallida in Southern Ukraine. The total diversity of lichens did nоt have a significant correlation with the total number of tree species due to the dominance of several tree species (Fraxinus excelsior, Quercus robur), while most other phorophytes are young and represented singly. All old parks should become local reserves to preserve the overall biological diversity in their territories, protect against illegal logging, and regulate potential recreational activities. Keywords: biodiversity, Graphis, Hyperphyscia, Sclerophora, Mykolaiv, Kherson, rare species. Старі штучні парки є важливою складовою природної та культурної спадщини півдня України, яка представляє значну різноманітність специфічних місцезростань для лишайників. Метою нашого дослідження було проаналізувати загальне різноманіття лишайників у старих парках, а також поширення рідкісних видів, та видів, що охороняються. Більшість матеріалів було зібрано під час експедиційних досліджень протягом 2017–2020 років у Херсонській та Миколаївській областях. У цілому, було виявлено 108 видів лишайників та 21 ліхенофільних грибів на території 17 старих парків. Найбільше різноманіття лишайників зафіксовано в парках «Лабіринт» (66 видів) та «Недогірський ліс» (61 видів). Ми виявили 18 видів лишайників (16,6 %), занесених до Червоного списку Херсонської та Миколаївської областей та 26 (24 %) рідкісних видів, які приурочені до штучних лісових біотопів. З огляду на це, старі парки є дуже важливими територіями для збереження різноманіття лишайників у степовій зоні України, а також унікальними місцезростаннями таких видів, як Graphis scripta, Hyperphyscia adglutinata, Sclerophora pallida на півдні України.Встановлено, що загальне різноманіття лишайників не мало статистично значущої кореляції із загальною кількістю порід дерев, що може бути пов’язано з домінуванням кількох порід дерев (Fraxinus excelsior, Quercus robur), тоді як більшість інших форофітів молоді та представлені одиничними екземплярами. Усі старі парки мають увійти до природно-заповідного фонду як ботанічні заказники для збереження загального біологічного різноманіття на своїх територіях, захисту від незаконних вирубок та регулювання потенційної рекреаційної діяльності. Ключові слова: біорізноманіття, Graphis, Hyperphyscia, Sclerophora, Миколаїв, Херсон, рідкісні види.

The article describes the results of studies of the factors affecting lichen diversity in 46 manor parks of the region of Pskov. The investigated parks were founded in the end of XVIII – beginning of XX centuries. Twenty of them are fragmented and currently occupy less than 5 ha, the area of nine parks varies from 5 to 10 ha, those preserved within historical boundaries cover from 11 to 100 ha. Manor parks are situated both within the settlements’ boundaries (31 parks) and outside the settlements either bordering forest (12) or agricultural lands (3). Ten of the former border the forests. During the study 166 lichen species were identified. Statistical methods were performed to investigate the factors affecting lichen diversity in manor parks. Linear regression analysis was used to examine the dependence of the lichens species number on the park age/date of park creation (dispersion pattern), area of the parks (box plot), substrata diversity (dispersion pattern), and the dependence of the epiphytic lichens species number on tree and shrub species diversity (dispersion pattern). With the biserial correlation coefficient the impact of the settlement and the presence of the surrounding natural forests was calculated. Correlation analysis was performed to demonstrate the colligation between lichen species composition of the parks located in different subzones of forest zone in the region of Pskov. Our findings show that the number of lichen species depends on the park area (p = 0,0315), the variety of substrate types (p ˂ 0,001), and the variety of trees and bushes planted (p ˂ 0,001). The date of park creation and the presence of the surrounding natural forests do not influence the species diversity of lichens. We reveal that the location of the parks in a specific subzone of forest zone (southern taiga and mixed coniferous-broad-leaved forest) has no significant effect on the lichen species composition. The species richness of lichens tends to decrease in parks located within the settlements. The data obtained indicate not only the similarity of the species composition of lichens in the studied communities, but also the long-term development of lichen park communities in comparable climatic and landscape conditions.

The paper provides information about lichens found on the territory of the state natural reserve Zavolzhsky, which is a specially protected natural area of the Chuvash Republic. It was established for the protection of the unique natural landscape, located on the territory of Cheboksary and Cheboksary District, as well as for rare and endangered animals, plants and other organisms from high anthropogenic activity. As a result of lichen investigations (2011-2016) 134 species belong to 59 genera from 31 families of lichen flora were recorded. It emphasizes a high environmental significance of this territory. The paper shows substrate and biotope confinement for each lichen species. The investigations were conducted in detail-route method using a GPS-navigator. In the paper the locations of rare lichen species are given according to the new quarterly network of the Cheboksary forestry. We examined the lichen diversity in 14 quarters of 3 forest districts: Pihtulynskoe, Severnoe, Sosnovskoe; lichen collections were carried out in 36 habitats. The habitat of rare and endangered lichen Lobaria pulmonaria was found on the territory of the reserve. This species is included to the Red Data Book of Russia. According to the results of the study we recommend to include 15 rare lichen species to the new edition of Red Data Book of the Chuvash Republic: Arthonia cinereoprunosa , Acrocordia gemmata , Bryoria implexa , Bryoria subcana , Bryoria nadvornikiana , Dimerella pineti , Lobaria pulmonaria , Mycobilimbia epixanthoides , Mycobilimbia carneoalbida , Mycobilimbia tetramera , Platismatia glauca , Usnea dasopoga , Usnea lapponica , Usnea subfloridana , Xanthomendoza ulophyllodes.

AbstractThe edge effect of large clear-cuts on the epiphytic lichen flora of Picea abies in old-growth forest fragments was studied at three south-exposed and four north-exposed forest clear-cut edges in middle boreal Finland. The sampling of the species cover on trunk bases was carried out along four transects parallel to the forest margin: (1) at the forest margin, (2) 10 m from the margin, (3) 20 m from the margin and (4) 50 m from the margin. In addition, control trees were sampled > 100 m from nearest edge. Our results showed that the epiphytic lichen species diversity was lower at the forest margin than in the forest interior for sunny south-facing edges, while the species diversity in north-exposed edges was independent of the distance from the forest margin. The cover of a common and abundant lichen species, Parmeliopsis ambigua, was slightly higher at the forest edge and decreased inside the forest for both south-exposed and north-exposed edges.

There is debate about what drives and maintains the structure of arboreal lichen communities and the relative importance of substrate vs. local environment. Here, we examined which lichen species are unique to two tree species [Abies balsamea (L.) Mill. and Betula alleghaniensis Britton] in the boreal forests of the Avalon Peninsula, Newfoundland, and which environmental variables are most important for lichen colonization and community structure. We collected data on lichen diversity from tree boles along with environmental data (tree size, bark pH, canopy cover) for each tree and each site. Multivariate analyses were used to determine the relationship between community structure and environmental data. The results show that a diverse range of tree characteristics are needed to support a diverse range of lichen species. Certain stands, such as old B. alleghaniensis stands, are more suitable to host a unique community of lichens than others. These results can inform land managers on the Avalon, recommending strategies for protected areas and providing forest harvest guidelines that limit clear-cutting of A. balsamea to maintain a diverse community structure and limit harvest of B. alleghaniensis trees in sites less optimal for lichen growth. These baseline data can also be used to monitor changes caused by moose browse and selective harvesting, two locally important threats to lichen diversity.

In recent years there has been growing interest in the study on lichen diversity with relation to altitudinal gradient and anthropogenic disturbances , as changes in lichen community composition may indicate air quality and microclimatic changes. The altitudinal data of species diversity and its subsequent changes with respect to time and space may provide vital information regarding impact of air pollution and/or climate change at regional or global scales. Chopta-Tungnath and adjoining areas of Garhwal Himalaya provide habitat and ecological variation with range of altitude lying between 300 to 3000 m. Out of the 116 species of lichens known from the studied area, the highest species diversity was observed between altitudes 1800 to 2100 m. Lichen communities occurring between 600–1800 m were dominated by members of Physciaceae, while Parmeliaceae were most common above 1800 m. Altitude beyond 2100 m experiences high precipitation, varying temperature conditions and increased incident UV radiation, which are responsible for controlling the variability in lichen diversity to a great extent in the region. The diversity of secondary metabolites in lichen species and consequent changes in species composition at various altitudes indicate the association of secondary chemicals in conferring the lichens resistance to biotic and abiotic stresses. The correlations of lichen diversity, secondary metabolites and the altitudes at which the lichens are growing, present suggestive role of secondary metabolites in determining species composition and sustainability in different environmental conditions.
