JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2024; 20:70. [PMID: 39080759 PMCID: PMC11289975 DOI: 10.1186/s13002-024-00703-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Accepted: 07/01/2024] [Indexed: 08/02/2024]
Abstract
BACKGROUND Wild edible plants (WEPs) are usually considered to constitute all plant resources that are neither cultivated nor domesticated but are used as nutritional supplements by local people. WEPs play a vital role in ensuring food and livelihood security for countless families and communities around the world. The objective of the study was to assess and document wild edible plants used by communities in the Arsi Robe district as food. METHODS Semi-structured interviews, market surveys, and guided field walks were employed as data collection tools. The data were analyzed using preference ranking, direct matrix ranking, and Jaccard's similarity index. RESULTS The present study revealed various types of wild edible plants consumed by local communities in the Arsi Robe district of the East Arsi Zone. This could be justified by the documentation of 36 different wild edible plants in the study area. These WEPs belong to 31 genera and 25 families. Most of the growth forms of the edible wild plants in the district were shrubs (16, 44.44%) and trees (14, 38.88%). Amaranthus caudatus and Bridelia micrantha are the most preferred WEPs in the study area. The finding of the study also revealed that Lepidotrichilia volkensii and Premna schimperi are among the novel WEPs that had not before been documented as food items in other areas. Olea europaea subsp. cuspidata, Ficus sycomorus, Cordia africana, and Ficus sur are species with multiple uses. Agricultural expansion, charcoal production, the construction of different materials, making agricultural tools, deforestation, and other factors were the top prioritized threats affecting the abundance and diversity of wild edible plants. CONCLUSION Along with the sustainable utilization and conservation of the existing WEPs of the study district, priority should be given to the urgent collection, domestication, and cultivation of multiuse wild edible plant species such as Olea europaea subsp. cuspidata, Ficus sycomorus, Cordia africana, and Ficus sur in the study area.

Wang F, Sun T, Yu S, Liu C, Cheng Z, Xia J, Han L. Ethnobotanical studies on rice landraces under on-farm conservation in Xishuangbanna of Yunnan Province, China. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2024; 20:45. [PMID: 38685098 DOI: 10.1186/s13002-024-00683-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Accepted: 04/01/2024] [Indexed: 05/02/2024]
Abstract
BACKGROUND A complex interaction and mutual influence exists among landscapes, cultures, and landraces, with rice culture being a typical embodiment of this relationship. The conservation of landraces operates alongside preserving traditional practices. The Xishuangbanna region stands out as a hub for the genetic diversity of landraces, boasting rich genetic resources. Despite the diverse rice resources in this region, a comprehensive and systematic study has not been undertaken. METHODS From October to November 2023, we collected rice landraces under the on-farm conservation in 18 townships including Menghai, Mengla and Jinghong in Xishuangbanna. Employing semi-structured interviews and various methods, we investigated factors influencing the preservation and loss of rice landraces in the region. Statistical analysis was applied to the agronomic traits of collected local rice, encompassing indica or japonica, glutinous or non-glutinous, grain shape, and hull color as second category traits. The second category included quantitative traits like thousand grain weight and grain length. Rice diversity among different regions, traits, and ethnic groups was assessed using the Shannon-Wiener index. Additionally, clustering analysis via the UPGMA method depicted the distribution characteristics of the resources. RESULTS A total of 70 rice landraces were collected in the Xishuangbanna region, each exhibiting distinct characteristics. Differences were observed across regions, trait, naming, and ethnic groups. Diversity analysis revealed that Mengla had the highest diversity, followed by Menghai, while Jinghong exhibited the lowest diversity. The second category of traits displayed broader diversity than the first, with the Dai people's glutinous rice showcasing greater diversity than other ethnic groups. Cluster analysis categorized the 70 samples into seven groups at a genetic distance of 1.15. Ethnobotanical interviews emphasized the rapid loss of rice landraces resources in Xishuangbanna, with indigenous ethnic cultures playing a vital role in the conservation of rice landraces. Dai traditions, in particular, played a crucial role in protecting glutinous rice resources, showcasing a mutual dependence between Dai culture and glutinous rice. CONCLUSIONS The rich natural environment and diverse ethnic cultures in Xishuangbanna have given rise to various rice landraces. The Dai, primary cultivators of glutinous rice with higher diversity, intertwine their traditional ethnic culture with the conservation of glutinous rice resources. At the same time, the preserving glutinous rice resources promotes the inheritance of Dai ethnic culture. However, rice landraces are facing the risk of loss. Hence, collecting and documenting rice landraces is crucial. Encourage local communities to sustain and expand their cultivation, promoting on-farm conservation. These measures contribute valuable germplasm and genes for rice breeding and serve as a means of cultural preservation.

JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2024; 20:37. [PMID: 38500123 PMCID: PMC10946099 DOI: 10.1186/s13002-024-00676-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Accepted: 03/11/2024] [Indexed: 03/20/2024]
Abstract
BACKGROUND Homegardens are small-scale land use systems with significant implications for local livelihoods, biodiversity conservation, and sustainable development due to their diverse flora and fauna. Conducting homegarden surveys enables researchers to gain insights into the traditional ecological knowledge of indigenous communities, preserve homegarden biodiversity, and promote sustainable livelihoods. This study has two objectives: first, to collect, record, and organize data on homegarden plants and related traditional knowledge from three communities in the Laershan Plateau, and second, to analyze the species and functional diversity of homegarden plants in the region while exploring the factors that contribute to the heterogeneous distribution of these plants among the communities of three townships. METHODS This research employed field surveys in the Laershan Miao Autonomous Region in Xiangxi, China, from September 2021 to August 2023. Data were collected through observation and semi-structured interviews. The study utilized descriptive statistics and quantitative analysis, including the Relative Importance Value (RI), Use Value Index (UV), Jaccard Index (JI), and Comprehensive Index of Land Use Degree (La), to examine the diversity of local homegarden plants and related traditional knowledge, as well as community heterogeneity. RESULTS The study area exhibited rich biodiversity, with 152 plant species recorded belonging to 62 families and 124 genera. These findings highlight the importance of homegarden plants in maintaining ecological balance and enhancing system resilience against disturbances. Homegarden plants serve multiple functions such as food, ornamental, medicinal, and fodder purposes, with edible and trade plants having the most abundant knowledge. Furthermore, this research revealed that communities with similar forest resource compositions may have similar homegarden plant compositions, demonstrating the connection between cultural exchange among different communities and patterns of plant species distribution. CONCLUSIONS The Laershan region boasts diverse homegarden plant species crucial for ecological balance and resilience. Their multifunctionality reflects human impact. Plant diversity varies with residents' lifestyles, needs, and cultural exchanges. The close connection between plants and local life is clear. Factors like resource distribution, cultural exchange, and lifestyle influence plant distribution. Further research is needed for conservation and sustainable development. Future research should focus on culturally valuable plant species and traditional knowledge applications.

JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2024; 20:10. [PMID: 38225656 PMCID: PMC10790445 DOI: 10.1186/s13002-023-00638-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 12/13/2023] [Indexed: 01/17/2024]
Abstract
BACKGROUND Traditional knowledge associated with medicinal food plants (MFPs) plays a vital role in fighting hidden hunger and safeguarding the health of local people. MFPs resources are abundant in the Gaoligongshan area, a biosphere reserve with the richest biocultural diversity in China. Local people of different linguistic groups also have rich traditional botanical knowledge. However, there are still few comprehensive and systematic studies on MFPs there. METHODS Ethnobotanical investigation including market survey, semi-structured interviews, free listing and key informant interviews was conducted in the Gaoligongshan area, Western Yunnan, Southwest China. A total of 13 local farmers' markets were selected and information about medicinal food plants, including food categories, medicinal and edible parts, modes of consumption, medicinal effects, and distribution were collected. The relative occurrence frequency (RFO) and cultural food significance index (CFSI) were calculated to identify the culturally significant MFPs. RESULTS A total of 184 species of MFPs, belonging to 83 families, were collected in the Gaoligongshan area, including vegetables (77), medicinal diets (26), fruits (25), spices (18), herbal tea (13), tea substitutes (11), substitutes for staple food (8), nuts (5), oils and fats (4), and dye material (1). The most frequently used families were Fabaceae, Asteraceae and Apiaceae, with 11, 10, and 9 species, respectively. The most frequently used plant parts were the stems, followed by fruits and leaves. Based on the evaluation results of the CFSI and RFO indices, 18 species of MFPs with magnificent local cultural importance have been screened out, such as Houttuynia cordata, Eryngium foetidum, Sechium edule, Centella asiatica and Pseudocydonia sinensis. CONCLUSION These findings have guiding significance for conservation of traditional knowledge associated with MFPs and facilitation of scientific utilization of MFPs to meet local people's needs for a healthy life.

Liu S, Huang X, Bin Z, Yu B, Lu Z, Hu R, Long C. Wild edible plants and their cultural significance among the Zhuang ethnic group in Fangchenggang, Guangxi, China. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2023; 19:52. [PMID: 37940945 PMCID: PMC10631048 DOI: 10.1186/s13002-023-00623-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 10/25/2023] [Indexed: 11/10/2023]
Abstract
INTRODUCTION Fangchenggang is situated in the Guangxi Zhuang Autonomous Region, China, renowned for its rich biodiversity and ethnically diverse population. The Zhuang people, constituting the largest minority group in the area, possess a wealth of traditional knowledge concerning wild edible plants (WEPs) owing to the region's favorable environment and dietary customs. With the rapid development of urbanization, tourism, and trade, the Zhuang people's food culture, including the consumption of wild edible plants, has become an attractive aspect of urban development. However, there is almost no comprehensive report available on WEPs consumed by the Zhuang people. The objectives of this study were to: (1) conduct a comprehensive ethnobotanical investigation of the WEPs among the Zhuang people in the region; (2) evaluate the cultural food significance index (CFSI) for the local communities; (3) summarize the cultural characteristics of the wild edible plants consumed, providing scientific support for the development of Fangchenggang as a sustainable and attractive tourism destination. METHODS Ethnobotanical investigation including market surveys, semi-structured interviews, key informant interviews and participatory observations was conducted in Fangchenggang from January 2021 to March 2023. A total of 137 informants were selected using the snowball method. Information about WEPs, including vernacular names, food categories, parts used, mode of consumption, collecting season, and recipes, was collected and recorded. The CFSI (cultural food significance index) was calculated to identify the most culturally significant WEPs. RESULTS A total of 163 species of wild edible plants consumed by the Zhuang people were identified, belonging to 67 families. The main categories of WEPs include wild vegetables (69) and tea substitutes (42). The most commonly consumed parts are fruits (37), followed by whole plants (33) and leaves (21), with herbaceous plants (74) being the most numerous. The availability of wild edible plants remains high throughout the year, with the peak seasons occurring in August and October, and significant abundance also noted in July and November. In the highly significant category (CFSI > 500), a total of 15 plant species were identified, which play a crucial role in the local diet. Additionally, 17 alien species have become part of the local consumption of wild plants, with 7 species listed as invasive alien species. DISCUSSION AND CONCLUSIONS: This study documented 163 wild edible plant species and their associated traditional knowledge of the Zhuang people. The research identified culturally significant WEPs and analyzed their multiple uses. The historical development of wild plant consumption in Fangchenggang showed the strong influence of natural and social environments on the Zhuang ethnic group's dietary traditions. The WEPs are characterized by "sour food", "fresh ingredients" and "cold dishes", aligning with their health-oriented philosophy of "homology of medicine and food". Future prospects encompass the cultivation of economically sustainable wild edible plants (WEPs), the preservation of their traits through cross-breeding, ensuring safe consumption through research and safety evaluations, and advocating for the preservation of WEPs' culinary culture to support tourism and sustainable urban development.

Wang J, Ding X, Guo CA, Zhang X, Feng H, Yang H, Wang Y. An ethnobotanical study of wild edible plants used by the Tibetan in the Rongjia River Valley, Tibet, China. JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE 2023; 19:49. [PMID: 37891585 PMCID: PMC10612173 DOI: 10.1186/s13002-023-00621-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 10/20/2023] [Indexed: 10/29/2023]
Abstract
BACKGROUND Wild edible plants (WEPs) play a crucial role in communities with limited communication with the outside world, where unstable factors, such as poor food supply and insufficient access to timely nutritional supplementation, are common, as in the Himalayan region. To document the traditional knowledge of WEPs and explore their significance for communities with minimal global economic exchange, an ethnobotanical study was conducted in the town of Rongjia, which lies in a narrow valley near Mount Everest, Tibet, China. METHODS This ethnobotanical study was conducted in three villages in the Rongjia River Valley between August 2021 and June 2023. Semi-structured interviews and participatory observations were used to collect information on WEPs. The fieldwork was performed with the assistance of local guides. Voucher specimens were collected from each documented plant species for taxonomic identification. We used the use report (UR) and relative frequency of citations (RFC) to evaluate the comprehensive utilization value of WEPs. RESULTS We interviewed 161 informants who provided us with 2499 use reports. We collected 50 WEPs belonging to 28 families and 42 genera used by the Tibetan people in the Rongjia River Valley. WEPs are used in vegetables, fruits, seasonings, healthcare foods, substitute grains, and beverages. Wild vegetables were the most commonly used, followed by wild fruits. Leaves were the most commonly consumed part of the plant. The three most important WEPs ordered by RFC values were Rosa sericea var. glandulosa Osmaston (RFC = 0.76), Zanthoxylum bungeanum Maxim. (RFC = 0.75), and Urtica hyperborea Jacquem. ex Wedd. (RFC = 0.71). Other than that, we also document some of WEPs used in the past. Arisaema erubescens Schott, Pinellia ternata (Thunb.) Makino, and Satyrium nepalense var. ciliatum (Lindl.) Hook. f. used to serve as important substitute grains, are no longer in use, however, they remain vivid in the memories of older people. CONCLUSIONS WEPs included wild vegetables, fruits, seasonings, healthcare food, and substitute grains for Tibetan people in the Rongjia River Valley. Some WEPs have become important cultural symbols for older people, which can help in understanding the relationship between plants and local people in the past. In addition, WEPs can increase the resilience of local people living in remote areas when facing sudden destabilizing events in future. This is the significance of WEPs for communities with minimal global economic exchange. Therefore, we suggest that future studies focus more on WEPs in communities with limited communication with the world to improve their resilience.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2023; 2023:7837615. [PMID: 37408582 PMCID: PMC10319463 DOI: 10.1155/2023/7837615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 05/28/2023] [Accepted: 05/30/2023] [Indexed: 07/07/2023]
Abstract
The purpose of this study was to carry out an ethnobotanical and ethnopharmacological investigation on wild edible plants and their value to households in the Tach Gayint district of South Gondar Zone of northwestern Ethiopia. A total of 175 informants (56 women and 119 males) were interviewed for ethnobotanical data, and 25 of them were key informants. Data collection techniques included semistructured interviews, guided field walks, and focus group discussions. Quantitative analytical tools were employed for ethnobotanical methods including preference ranking and direct matrix ranking techniques to analyse the data. 36 species of wild edible plants have been identified in the study area. Of these plant species, shrubs account for 15 (42%), followed by herbs 13 (36%) and trees 8 (22%). Regarding the edible parts, fruits account for 19 (53%) followed by young shoots, leaves, and flowers, 4 (11%) for each. These plant species are eaten raw (86%) or cooked (14%) and most are collected by younger people for herding cattle. According to the preference ranking analysis, the fruit of Opuntia ficus-indica is the most preferred plant species because its sweet taste. Although Cordia africana, the most commonly used multipurpose wild edible plant species, is mostly exploited due to human activity, activities such as the production of charcoal, the gathering of firewood, the construction of homes, and the use of agricultural tools all played a significant role in the plant's eventual extinction. In the study area, agricultural expansion was the main cause of putting wild edible plants in danger. It is best to cultivate and manage edible plants in a backyard garden and to perform more research on popular edible plant species.

[PMID: 36814353 PMCID: PMC9948460 DOI: 10.1186/s41182-023-00505-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 02/18/2023] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND The populations in Ethiopia have developed their indigenous knowledge to use, manage and conserve wild edible plants (WEPs). In the eastern part of Ethiopia, wild edible plants are used as a means of survival during times of food shortage and as dietary supplements. Documenting the traditional and cultural use of wild food plants is a vital step in obtaining baseline data for investigating nutritional values and possible side effects, preserving indigenous knowledge, and ultimately interesting in wild edible plant conservation. However, their significance, management and utilization have not been documented in Mieso District. Therefore, this study aimed to provide documentation of wild edible plant use associated with ethnobotanical knowledge in Mieso District, eastern Ethiopia. METHODS An ethnobotanical study of wild edible plant species was conducted from March 2021 to May 2022. A total of 120 (72 males and 48 females) informants were selected using the snowball method. Data collection methods, including semistructured interviews, direct observation and field walks were used. Data were analysed using descriptive statistics, including independent sample t test and analysis of variance (ANOVA). We calculated use values (UVs) to analyse the relative cultural importance of each plant species. RESULTS A total of 41 wild edible plant species belonging to 33 genera in 21 families were documented to be used as food sources both during times of food shortage and as dietary supplements. Family Malvaceae was best-represented with 6 species, followed by Fabaceae and Rhamnaceae (4 species each). The dominant growth form (habit) was shrubs (30 species), followed by trees (11 species). The most widely used plant parts were fruits (covering 39 species, 95%). The largest number (23 species) was collected from forest habitats only, followed by both village and forest habitats (8 species). The majority of wild edible plants (28 species or 68%) were consumed only during famine or in the time of food shortage followed by supplementing staple foods (9 species or 22%). Wild edible plants in Mieso are used for multiple other uses, including for fodder, fuel, medicine, construction, cosmetics and bee keeping. Twenty-three species were mentioned for fodder use, followed by fuel purpose (21 species) and medicinal value (13 species). The species that had the highest use values were Flacourtia indica (Burm.f.) Merr. (1.4), Carissa spinarum L. (1.1), Ziziphus spina-christi (L.) Desf. (0.6), Grewia villosa Willd. (0.5), Cordia monoica Roxb. (0.3) and Opuntia ficus-indica (L.) Mill. (L.) (0.2). Most WEPs were collected from March to May (Badheysa) (33 species). The highest mentioned wild edible plant sold in the market was F. indica (Burm.f.) Merr. mentioned by 20 informants, followed by Z. spina-christi (L.) Desf. (14). CONCLUSION The people in Mieso use wild plants as supplementary food to cultivated crops, during famine, and many could be utilized for day-to-day human consumption. Some plants in the district provide cash income for local people. However, deforestation (54%), drought (22%) and agricultural expansion (12%) were the highest threats to wild plants in Mieso District. Hence, on-site and off-site conservation would help protect wild plant resources in Mieso, eastern Ethiopia.

Dulong People's Traditional Knowledge of Caryota obtusa (Arecaceae): a Potential Starch Plant with Emphasis on Its Starch Properties and Distribution Prediction. ECONOMIC BOTANY 2023; 77:63-81. [PMID: 36811019 PMCID: PMC9934947 DOI: 10.1007/s12231-022-09565-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 12/28/2022] [Indexed: 06/18/2023]
Abstract
The greatest global challenge is to ensure that all people have access to adequate and nutritious food. Wild edible plants, particularly those that provide substitutes for staple foods, can play a key role in enhancing food security and maintaining a balanced diet in rural communities. We used ethnobotanical methods to investigate traditional knowledge on Caryota obtusa, a substitute staple food plant of the Dulong people in Northwest Yunnan, China. The chemical composition, morphological properties, functional, and pasting properties of C. obtusa starch were evaluated. We used MaxEnt modeling to predict the potential geographical distribution of C. obtusa in Asia. Results revealed that C. obtusa is a vital starch species with cultural significance in the Dulong community. There are large areas suitable for C. obtusa in southern China, northern Myanmar, southwestern India, eastern Vietnam, and other places. As a potential starch crop, C. obtusa could substantially contribute to local food security and bring economic benefit. In the future, it is necessary to study the breeding and cultivation of C. obtusa, as well as the processing and development of starch, to solve long-term and hidden hunger in rural areas.

[PMID: 36401315 PMCID: PMC9675253 DOI: 10.1186/s13002-022-00565-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 11/10/2022] [Indexed: 05/23/2023]
Abstract
BACKGROUND Gyirong Valley known as the "Back Garden of the Himalayas" is located in the core area of the Everest National Nature Reserve. It is also one of the important ports from ancient Tibet to Kathmandu, Nepal, since ancient times. Over the years, the Tibetans of Gyirong had accumulated sufficient traditional knowledge about local plant resources. However, there is almost no comprehensive report available on ethnobotanical knowledge about the local people. The purposes of this study were to (1) conduct a comprehensive study of wild plants used by Tibetan people in Gyirong Valley and record the traditional knowledge associated with wild useful plants, (2) explore the influence of Tibetan traditional culture and economic development on the use of wild plants by local people, and (3) explore the characteristics of traditional knowledge about wild plants of Tibetans in Gyirong. METHODS Ethnobotanical data were documented through free listings, key informant interviews and semi-structured interviews during fieldwork. The culture importance index and the informant consensus factor index were used as quantitative indices. RESULTS In total, 120 informants (61 women and 59 men) and 3333 use reports and 111 wild plant species belonging to 39 families and 81 genera were included. These use reports were then classified into 27 categories belonging to three major categories. The use category that contained the most plant species was edible plants (62), followed by medicinal plants (32) and economic plants (22), and other uses (71). Plants with high CI included Allium prattii, Neopicrorhiza scrophulariiflora, Gymnadenia orchidis, Rhododendron anthopogon and Fritillaria cirrhosa. Thirty-six species of plants in the catalog of Gyirong and Yadong were the same, but only 17 species were the same in Gyirong and Burang. There were only 11 overlapping species between all the three regions. CONCLUSION Tibetans of Gyirong have rich and unique knowledge about plant use, and wild edible and medicinal plants play an important role in the nutrition and health protection of local people. However, traditional knowledge is slowly being lost and is being hit by modern tourism. In the future, more attention needs to be paid to the important role of traditional knowledge in biodiversity conservation.

Abstract
INTRODUCTION In recent years, research on wild edible plant resources has become increasingly popular. The Hassan Nature Reserve is a multiethnic area mainly composed of people belonging to the Han, Hui, and Mongolian groups. The utilization of edible wild plant resources in this area is extremely high. However, with the advancement of urbanization and the development of modern agricultural technology, these resources have been seriously damaged, and related traditional knowledge, such as that related to national medicine, has been lost. METHODS Based on a literature study, interviews with village and community organizations, participatory observation, and quantitative evaluation of ethnobotanical resources, wild edible plants in the Gansu-Ningxia-Inner Mongolia junction zone, were investigated. RESULTS The survey results showed that there were 53 species (varieties) of wild edible plants belonging to 24 families in this area. The Compositae and Liliaceae families were the most abundant, with 8 and 7 species, respectively. The young stems and leaves were the most edible parts of the plants, as observed for 17 species, followed by fruits (including young fruits), which were considered the edible part of 16 species. Other edible parts included the roots or rhizomes (bulbs), seeds, whole plants, skins, etc. The edible plants were consumed in two forms: raw and cooked; raw plants, mainly fruit, were typically consumed as snacks. The cooked foods mainly consisted of vegetables, with tender stems and leaves as the main food source. These components were also used as seasoning, in medicinal diets, and as an emergency food source in times of famine. Important (CFSI > 500) wild edible plants used in health care in the region include Mulgedium tataricum (L.) DC., Nostoc commune Vaucher ex Bornet & Flahault, Sonchus arvensis L., Taraxacum mongolicum Hand.-Mazz., Allium schoenoprasum L., Robinia pseudoacacia L., Hemerocallis citrina Baroni, Elaeagnus angustifolia L., Medicago sativa L., Ulmus pumila L., Stachys sieboldii Miq., and Toona sinensis (Juss.) M. Roem., and these plants had high utilization values and rates locally. CONCLUSION In summary, the species of wild edible plants and their edible parts, categories, consumption forms and roles in health care in this area are diverse. The utilization of traditional knowledge is rich, and some wild plants have high development value.

Abstract
The Dulong, an ethnic group living in the isolated Northwest Yunnan of Southwest China, have directly used a wide of plants to serve their needs and have accumulated rich traditional knowledge about medicinal plants over years. Unfortunately, little has been reported about the medicinal plants used by the Dulong people. Ethnobotanical data were collected through semi-structured interviews, guided field trips, and quantitative analysis. Prior informed consent was obtained before each interview. The surveys allowed for the collection of sociodemographic data and traditional knowledge about medicinal plants and their uses. This study used relative frequency of citation (RFC) to identify the most culturally significant medicinal plants and used informant consensus factor (FIC) to evaluate agreement among informants. A total of 105 medicinal plant species belonging to 69 families were recorded. Amongst these 69 families, Asteraceae (8 species), Polygonaceae, Ranunculaceae, and Rosaceae (4 species each) were the dominant families. The whole plants were the most frequently used part in the preparation of medicines. The most common preparation method was decoction and the most frequent application route was oral administration. Coptis teeta (0.15), Acorus calamus (0.12), Ophiocordyceps sinensis (0.11), Tanacetum tatsienense var. tanacetopsis (0.11), and Paris polyphylla var. yunnanensis (0.08) were shown to be the most useful plants as indicated by their relatively high RFC values. Among the usage types of medicinal plants, the highest FIC values were recorded for the circulatory system (FIC = 0.91), the immune system (FIC = 0.89), and the nervous system (FIC = 0.85). Furthermore, sixty-two medicinal plants utilized by the Dulong for medicinal purposes also have dietary use. Traditional knowledge associated with medicinal plants has been seriously threatened in recent decades. In the future, modern approaches should be used to demystify traditional medicine. However, significant measures need to be taken to protect from loss the important traditional knowledge gained by the Dulong through their experience and inheritance. A collective effort should be made to promote and conserve the important traditional medicinal knowledge and outline a plan for sustainable use of medicinal plants and improve local economic development under the premise of protection.

Abstract
BACKGROUND In the past, wild edible fruits (WEFs) were a significant source of food and nutrition in Bhutan. These nutrient-rich species can enhance food security and alleviate poverty in Bhutan. However, recent developments like the introduction of improved fruit varieties, changes in dietary choices, and infrastructure development are expected to influence indigenous knowledge and consumption of WEFs. We aimed to document the species diversity of WEFs and their uses in eastern Bhutan and examine how the knowledge and consumption of WEFs vary with socio-demographic factors. METHODS A total of 97 households in two districts were selected to participate in the survey. A semi-structured questionnaire was used to interview a selected adult from each household. Comparative analysis of indigenous knowledge and consumption of WEFs among the socio-demographic factors was performed using one-way ANOVA and a Chi-square test on R software. RESULTS The present study reported 52 species of WEFs belonging to 35 families. The prevalence of WEF consumption was found to be 42%. WEF consumption differed significantly between districts, age groups, and indigenous knowledge levels. Similarly, indigenous knowledge of WEFs was significantly associated with districts and age groups. CONCLUSIONS Eastern Bhutan has a rich diversity of WEFs, but their consumption has been decreasing. Recent agricultural and infrastructure developments may have impacted the consumption and indigenous knowledge of WEFs in this region. Thus, domestication and agro-processing of WEFs should become a major focus in Bhutan to utilize their nutritional value and potential economic benefits to enhance food security in the country. Additionally, incorporating WEF-related knowledge in the school curriculum is essential to educate younger generations on WEFs.

Abstract
BACKGROUND The local Dong people in Qiandongnan Prefecture, Guizhou Province, China, with rich biocultural diversity, have developed the traditional rice-duckweed-fish-duck agroecosystem (RDFDA) to support biodiversity conservation and to meet food and cultural needs. However, there is still not much research on traditional ecological knowledge (TEK) in this area. In particular, there is a lack of traditional knowledge of edible plants used by the Dong people as flavoring to grill fish (Cyprinus carpio) collected from RDFDA, which is extremely valuable in their traditional culture. The study focused on documenting plant species used in grilling fish and analyzing the status of its TEK. METHODS Twenty-one sampling points of three Dong minority villages in Qiandongnan were selected for the research. The local TEK associated with plant resources for fish-grilling was recorded through free listing and semi-structured interviews. Fidelity level (FL) and ethnoecological importance value (EIV) indicators were designed to determine the socioeconomic influence of TEK. The non-metric multidimensional scaling (NMDS) method was used to evaluate the differentiation of edible plant species distribution in dissimilar accessibility types. RESULTS A total of 430 people were interviewed about grilled fish, of whom 75% were men and 85% were farmers. Thirty-four edible plants were documented for fish-grilling in three Dong villages. They belong to 16 plant families, such as Apiaceae, and Asteraceae. The life forms included herbaceous (76%), shrubs (18%) and trees (6%). Leaves are the most commonly used part of for grilling fish, followed by aerial parts, and whole plants. Among these edible plants, Allium hookeri, A. macrostemon and Houttuynia cordata with the highest fidelity level (100%) were cited as edible plants for grilling fish by all informants. The NMDS showed different accessibility types of collection sites, with different importance values. Paddy rice field edge (2.03) has the highest value, followed by forest-farming ecotone (1.74), streamsides (1.71) and woodland (0.48). CONCLUSION The purpose of this study was to investigate the traditional knowledge of edible plant materials used by the Dong people for grilling fish. The results demonstrate the strong connection between local people, the bio-environment and agroecosystem services. The survey and comparative analysis revealed that plant species with high FL values may be potential sources of natural flavors.
