While the current consumption of wild food plants in the taiga of the American continent is a relatively well-researched phenomenon, the European taiga area is heavily underrepresented in the scientific literature. The region is important due to its distinctive ecological conditions with restricted seasonal availability of wild plants. During an ethnobotanical field study conducted in 2018–2019, 73 people from ten settlements in the Republic of Karelia were interviewed. In addition, we conducted historical data analysis and ethnographical source analysis. The most widely consumed wild food plants are forest berries (three Vaccinium species, and Rubus chamaemorus), sap-yielding Betula and acidic Rumex. While throughout the lifetime of the interviewees the list of used plants did not change considerably, the ways in which they are processed and stored underwent several stages in function of centrally available goods, people’s welfare, technical progress, and ideas about the harm and benefit of various products and technological processes. Differences in the food use of wild plants among different ethnic groups living in the region were on the individual level, while all groups exhibited high variability in the methods of preparation of most used berries. The sustainability of berry use over time has both ecological and economical factors.

Socio-economic changes impact local ethnobotanical knowledge as much as the ecological ones. During an ethnobotanical field study in 2018–2019, we interviewed 25 Setos and 38 Russians in the Pechorsky District of Pskov Oblast to document changes in wild plant use within the last 70 years according to the current and remembered practices. Of the 71 botanical taxa reported, the most popular were Vaccinium vitis-idaea, Vaccinium oxycoccos, Vaccinium myrtillus, Betula spp., and Rumex acetosa. The obtained data was compared with that of 37 Setos and 35 Estonians interviewed at the same time on the other side of the border. Our data revealed a substantial level of homogeneity within the plants used by three or more people with 30 of 56 plants overlapping across all four groups. However, Seto groups are ethnobotanically closer to the dominant ethnic groups immediately surrounding them than they are to Setos across the border. Further study of minor ethnic groups in a post-Soviet context is needed, paying attention to knowledge transmission patterns.

This first inventory of the charophytes of the Caucasus region was compiled based on records from published references, online sources, a review of herbarium collections, and our own field collections. The documented Caucasian charophyte flora includes 27 species from six genera: 18 Chara species, 6 Nitella, 2 Tolypella, and 1 species each of Lamprothamnium, Nitellopsis, and Sphaerochara. Chara uzbekistanica, C. virgata, and C. contraria var. hispidula are newly recorded for the Caucasus. The high species richness of the genus Chara, the much less diverse genus Nitella, and a few species of Tolypella and Sphaerochara in the Caucasian charophyte flora are typical traits of Palearctic charophyte floras. In total, there are 10 species recorded in Armenia, 16 in Azerbaijan, 18 in Georgia, and 16 in the mountainous region of the North Caucasian Federal District of Russia. Most of the species have wide distributions; none are endemic to the Caucasus. One of the most commonly recorded species in the region, C. gymnophylla, is a usual feature of the Mediterranean and West Asia. The Caucasian charophyte flora can be described as unsurprising from a large-scale perspective, considering its species distribution ranges. However, the association of species makes the region specific at the scale of West Asia when comparing it to its large neighboring areas.
