Background The Mountains of the Western Lesser Caucasus with its rich plant diversity, multicultural and multilingual nature host diverse ethnobotanical knowledge related to medicinal plants. However, cross-cultural medicinal ethnobotany and patterns of plant knowledge have not yet been investigated in the region. Doing so could highlight the salient medicinal plant species and show the variations between communities. This study aimed to determine and discuss the similarities and differences of medicinal ethnobotany among people living in highland pastures on both sides of the Georgia-Turkey border. Methods During the 2017 and 2018 summer transhumance period, 119 participants (74 in Turkey, 45 in Georgia) were interviewed with semi-structured questions. The data was structured in use-reports (URs) following the ICPC classification. Cultural Importance (CI) Index, informant consensus factor (FIC), shared/separate species-use combinations, as well as literature data were used for comparing medicinal ethnobotany of the communities. Results One thousand five hundred six UR for 152 native wild plant species were documented. More than half of the species are in common on both sides of the border. Out of 817 species-use combinations, only 9% of the use incidences are shared between communities across the border. Around 66% of these reports had not been previously mentioned specifically in the compared literature. Only 33 species have similar use reports in both countries, most important of which are Plantago major, Urtica dioica, Picea orientalis, Anthemis spp., Sambucus ebulus, Achillea millefolium, Helichrysum rubicundum, Mentha longifolia, Pinus sylvestris var. hamata, Hypericum perforatum, Tussilago farfara, Helichrysum plicatum, Rumex crispus, Berberis vulgaris, and Origanum vulgare. More than half of species reported in each country were found to have more than one part of the plant valued for medicinal use. The most common way of using plants medicinally in both countries is drinking the water infusion of aerial parts with flowers. Based on CI index value, two-thirds of the salient 15 genera in both countries have use reports in at least seven medicinal use categories. While the most cited category with highest FIC is digestive in Georgia, it is skin category in Turkey. Patterns of medicinal plant knowledge among studied communities appear to be connected with more than one cultural factor, in particular ethnolinguistic diversity, cultural background, and access to multilingual written folk and scientific literature, or probably a combination of various factors. Conclusion Considering the regions’ floral similarity, common historical-cultural contact, and similar livelihood strategies of the communities, shared ethnomedicinal knowledge across the Georgia-Turkey border is quite low. Even though the impacts of accessing multilingual folk and scientific literature are likely to be significant, the factors that shape the medicinal plant knowledge patterns of the communities are shown to be variable among species, needing further research into intracultural diversity and socio-economical conditions, as well as the political history across the border.

Background: Livestock are an integral part of the transhumant life in the Caucasus. Maintaining the health and wellbeing of the animals has been a critical responsibility for pastoral communities. This study presents the wild plant species used for ethnoveterinary and fodder purposes by transhumant people on the both sides of Georgia-Turkey border.Methods: During two summers (2017)(2018), 119 participants were interviewed (74 in Turkey and 45 in Georgia) with semi-structured questionnaires. Cultural importance index (CI) and Relative frequency of citation (RFC) were used to evaluate the relative importance of species among communities.Results: In total 113 citations of 38 wild plant species for ethnoveterinary purposes, and 186 citations of 61 wild plant species as fodder were obtained in the study area. The most important species in ethnoveterinary were Veratrum album and Achillea millefolium in Georgia, and Veratrum album and Picea orientalis in Turkey. Aerial parts of the plants were the most frequently used part in Georgia while the root was in Turkey. Gastrointestinal problems were the most commonly mentioned diseases in Georgia while dermatological and parasitic diseases in Turkey. The majority of the plant species were mentioned to treat the ailments of cattle (37 species). Fabaceae, Polygonaceae and Asteraceae were the most mentioned families used as fodder in both countries. There were also several plants used as bedding for livestock and against evil eye in the study area.Conclusions: Pastoral way of life in the Western Lesser Caucasus still reflects living evidence of plant-based traditional ethnoveterinary knowledge and practices to support the health of livestock. The results of this study could be a base for future ethnoveterinary and animal feed research and contribute to organic animal husbandry in the region.

Recent ethnobotanical studies in the Caucasus, mainly in Georgia, reveal the significant ethnobotanical knowledge of local people related to wild edible plants. However, few studies have been conducted in the Lesser Caucasus, west Georgia, and Turkish Caucasus. This study aims to represent and evaluate the cultural importance of wild vegetable plants and their patterns of use along the Georgia–Turkey border. During the transhumance period in the summers of 2017 and 2018, 104 participants (65 in Turkey and 39 in Georgia) were interviewed using a semistructured questionnaire. The Cultural Importance Index and Relative Frequency of Citation were used to compare the relative importance of species in each region. The use of 83 wild plant species from 23 plant families as vegetables was documented, with 45 species recorded in Georgia and 72 species in Turkey. One-third of the recorded wild plant species and 52 use instances out of 122 species-use combinations were shared on both sides of the border. Women and men had mentioned almost the same number of species, and there was a nonsignificant correlation between the plant knowledge and age. Although there were no significant differences in the plant parts used, the way people used plants as vegetables varied significantly across the border. Considering the floral similarity across the border, the number of species used in common and shared vegetable plant knowledge was quite low. There is not a significant difference between the two countries in terms of the most frequently cited and culturally important species ( Rumex , Urtica , and Polygonum spp.). However, the recognition of some of the most important shared species ( Heracleum , Chaerophyllum , Arctium , and Campanula spp.) diverged significantly in different administrative regions.

Understanding plant significance across cultures and borders is a driving goal in ethnobotany. Often, empirical studies aim to highlight and explain variation in plant knowledge and uses between communities across national, geographic, and cultural boundaries. However, such studies underinvestigate commonality of values and practices between communities. In this cross-border study of highland pastoral communities in both Caucasian Georgia and Turkey, we propose and implement an approach that synthesizes Cultural Importance (CI) and Identified Cultural Importance (ICI) indices. We label this method a “Unified Cultural Keystone Species (UCKS)” approach. We demonstrate that such an approach is uniquely capable of perceiving shared Traditional Ecological Knowledge (TEK) and practices across cultures and borders. Our results identify three primary Cultural Keystone Species (CKS) that cut across cultural and political boundaries in the Western Lesser Caucasus. We argue that these findings allow for a more comprehensive understanding of ethnobotanical knowledge and practices in the study area. This, in turn, can enhance conservation and restoration strategies in the study region and beyond by highlighting the breadth of biocultural knowledge and value held within shared traditions and landscapes. By so doing, we show a way to heighten scientific perceptions of the importance of cultural and linguistic connections to environmental well-being in specific places.
