Forest as Stronghold of Local Ecological Practice: Currently Used Wild Food Plants in Polesia, Northern Ukraine

Local ecological practice (LEP, e.g., the everyday practice of collecting and using plants, including wild food plants) is shaped by nature (available local resources) and culture (local perceptions and knowledge on their usability), including a multitude of factors, among which language and geographical or cultural separation have been found to play crucial roles in affecting biocultural diversity. Also, proximity to the forest has been shown to increase the use of plants. We conducted ethnobotanical fieldwork within eastern and western regions of Ukrainian Polesia, during which we interviewed 118 people. Through semi-structured interviews, we recorded the distribution of the current uses of 70 wild food taxa. The analysis of use records revealed homogeneous distribution of use despite the geographical distance and different spoken dialects; however, we were able to single out the highly sylvan region of eastern Polesia as the area with highest biocultural diversity for the use of wild food plants. The results suggest that in the context of the overall homogenization of local ecological knowledge, the continued existence of unintended contact with nature through living and working in the forest may be the primary factor maintaining the broader LEP in the sylvan area of eastern Polesia. Місцева екологічна практика (MЕП, що включає повсякденну практику збору та використання дикорослих рослин у їжу) формується природою (місцевими ресурсами) та культурою (місцеві знання про їх використання), що включає безліч чинників, серед яких мова та географічне або культурне відокремлення відіграють вирішальну роль у впливі на біокультурне різноманіття. Також показано, що близькість до лісу збільшує використання рослин. Ми проводили етноботанічні польові роботи у двох областях Українського Полісся, в ході яких ми провели інтерв’ю з 118 людьми. За допомогою напівструктурованих інтерв’ю ми задокументували поточне використання 70 таксонів дикорослих рослин у їжу. Аналіз записів про вживання свідчить про однорідний розподіл використання, незважаючи на географічне розташування та різні розмовні діалекти; однак, ми змогли виділити лісистий регіон Східного Полісся як територію з найвищим біокультурним різноманіттям використання дикорослих рослин уїжу. Результати свідчать, що в контексті загальної гомогенізації місцевих екологічних знань, продовження існування контакту з природою живучи та працюючи в лісі може бути основним чинником, який підтримує ширшу MЕПу в лісовій зоні Східного Полісся

Contribution of spatially explicit models to climate change adaptation and mitigation plans for a priority forest habitat

Climate change will impact forest ecosystems, their biodiversity and the livelihoods they sustain. Several adaptation and mitigation strategies to counteract climate change impacts have been proposed for these ecosystems. However, effective implementation of such strategies requires a clear understanding of how climate change will influence the future distribution of forest ecosystems. This study uses maximum entropy modelling (MaxEnt) to predict environmentally suitable areas for cork oak (Quercus suber) woodlands, a socio-economically important forest ecosystem protected by the European Union Habitats Directive. Specifically, we use two climate change scenarios to predict changes in environmental suitability across the entire geographical range of the cork oak and in areas where stands were recently established. Up to 40 % of current environmentally suitable areas for cork oak may be lost by 2070, mainly in northern Africa and southern Iberian Peninsula. Almost 90 % of new cork oak stands are predicted to lose suitability by the end of the century, but future plantations can take advantage of increasing suitability in northern Iberian Peninsula and France. The predicted impacts cross-country borders, showing that a multinational strategy, will be required for cork oak woodland adaptation to climate change. Such a strategy must be regionally adjusted, featuring the protection of refugia sites in southern areas and stimulating sustainable forest management in areas that will keep long-term suitability. Afforestation efforts should also be promoted but must consider environmental suitability and land competition issues

Multi-functionality of the few: Current and past uses of wild plants for food and healing in LiubaÅ\u84 region, Belarus

Background: This study examined the use of wild plants in the food, medicinal and veterinary areas within a small territory limited to one village council in the LiubaÅ\u84 district of Belarus. The objectives of the research were to document the current and past uses of wild plants in this region for food and human/animal medication; to analyse the food, medicinal and veterinary areas in the context of wild plants; and to qualitatively compare the results with relevant publications concerning the wild food plants of Belarus. Methods: Fieldwork was carried out as a practical part of a development cooperation project in May 2016 in 11 villages of the LiubaÅ\u84 district. One hundred thirty-four respondents were selected randomly. Information about local uses of wild plants was obtained via semi-structured interviews and the folk-history method. Interview records were digitalized and the data structured in Detailed Use Records (DUR), which were divided into food, medicinal and veterinary areas and then analysed to ascertain local perceptions. Results: A total of 2252 DUR of wild plants were recorded. Eighty-eight wild plant taxa belonging to 45 plant families were used across all three areas. Of these, 58 taxa were used in the food, 74 in the medicinal and 23 in the veterinary areas. A relatively high percentage of the taxa were used in both the food and medicinal areas (55%) and an even greater percentage in both the medicinal and veterinary areas (87%). Comparison with earlier research on wild food plants shows the considerable difference among seldom-mentioned taxa or uses, showing possible regional differences despite the homogenization of the population during the Soviet era. Conclusions: As the majority of taxa with overlapping uses belonged to the most utilized plants, there appears to be clear a tendency to use plants in several different areas once they are brought into the home. This may be due to the need to maximize the versatility of limited resources. While the number of wild taxa used is relatively high, the mean number of taxa used per person is quite low, which indicates the relatively minor importance of wild plants in the respective areas in the study region. The low importance of snacks signals that unintended contact with nature has been lost

Current and Remembered Past Uses of Wild Food Plants in Saaremaa, Estonia: Changes in the Context of Unlearning Debt

It is widely agreed that in industrialized Europe, knowledge on the use of wild food plants shows a decreasing trend with few instances of valorization. We employed a folk history approach in order to understand the changes that have occurred in the use of wild food plants within the lifetime of the older generation living on Saaremaa Island. Comparing current and remembered past uses and evaluating temporal encounters afforded the understanding that, while the general picture of the use of wild food plants seems diverse and promising (89 plant taxa used, median 20 taxa used per person, Informant Consensus Index of 0.9), only 36% of uses have been practiced throughout life. Another third (34%) of uses existed as a childhood memory, which also encompassed taxa useful during times of food shortage, and 20% of the uses recorded were recently abandoned. The uses of wild food plants acquired later in life, at some point during adulthood (4%) or recently (6%), were few in number, rather temporal in nature and affected by fashion trends. To understand the temporal changes in the use of wild food plants and to identify the reasons causing those changes, it may be important for future researchers to document the exact time of the actual use. To ensure the survival of food security-related knowledge, during times of relative food abundance, it is important to ensure the continuity of the use of wild food plants on the family level by educating children through their participation in making food from wild plants
