This study documents wild food species in a locally managed forest by the inhabitants of nine villages in the Dolakha district, Nepal. It presents data on their diversity, and traditional knowledge on plant use, propagation and local domestication collected through household and key informant interviews, forest transects inventories and herbaria verifications. Sixty-two wild food plants belonging to 36 families were recorded; most of them (80%) have multiple uses. Many of the food plants are herbaceous (24 species) and produce fruits for consumption (46%). Most of the food plants are consumed by the local communities as snacks, and are supplementary and nutritionally important especially prior to the harvest of staple foods. Elder women (>35 years) are the most knowledgeable group, being able to describe the use of 65% of all edibles as compared to only 23% described by young men (<35 years). Many villagers also possess knowledge on the modes of propagation for the food plants that may be used in the process of domestication. The local communities expressed a strong desire for the establishment of community enterprises based on the wild food resources for long-term income generation sources. To accomplish this, development of collective co-operative strategies based on assessments of the biology, size of harvestable population, sustainable harvesting techniques, and marketing value and demand of promising species would be required. Moreover domestication potential based on species identified in this paper and other species that local communities have knowledge on ought to be encouraged through incentive and policy interventions.  相似文献

We carried out an ethno-medico-biological investigation in the interior of Bhadrak district, Odisha, India to explore the therapeutic use of traditional plants/animals by local inhabitants. The villagers and rural people used plant and animal species as medicine. We recorded therapeutic use of 18 plant species of 13 families and 12 animal species of seven taxonomic categories. Different plant/animal parts like bark, leaf, flower, seed, stem, root, whole plant, oil, blood, milk, urine and flesh were reported as used in raw or cooked form against 17 specific diseases. Prominent diseases treated by plant/animal remedies were asthma, cardiovascular ailments, diabetes, epilepsy, jaundice, malaria, skin disorder and rheumatism. This study provides a better database for future studies.  相似文献

Traditional systems of medicine have become a topic of global importance recently. Increased commercialization of economically important medicinal plants has resulted in overharvesting, threatening their survival. The present study was carried out to document the indigenous uses of medicinal plants by the local communities in and around Rema-Kalenga Wildlife Sanctuary, Bangladesh. Data collection was predominantly qualitative recording the species use, identifying their relative importance (RI) and assessing the informants’ consensus factor (Fic) on associated knowledge. We interviewed 140 households of the local community and 5 local herbal practitioners. A total of 44 plant species were in use to treat 33 ailments under 10 broad disease categories. Five species were found to have high use versatility (RI > 1), Emblica officinale L. being the most versatile. Respiratory problems scored the highest Fic value (0.56) involving the use of 30% of the species recorded. Terminalia bellerica Roxb., Sterculia villosa Roxb., Dillenia pentagyna Roxb. and Terminalia arjuna Bedd. were being harvested commercially. Use by the community, particularly for subsistence consumption, seemed to be sustainable, but commercial extraction of some species appeared unsustainable. Buffer zone-based commercial farming of medicinal plants with a commercial value could serve a dual purpose of assuring sustainable alternative income generation for local communities as well as conserving the natural resources in protected areas.  相似文献

Rural inhabitants make considerable use of wild resources from communal areas around their settlements, as well as from arable and residential plots. These wild resources compete with the main crops planted in arable plots and home gardens, but play a significant economic and nutritional role in rural livelihoods. This paper reports upon a conservative financial evaluation of the wild plant resources harvested from home gardens and arable plots by inhabitants of rural village in the Bushbuckridge lowveld (South Africa), and examines their importance relative to other domesticated crops. On average, each household made use of four to five species of wild plants growing on their residential plot, whereas the mean number of crop plants was 3.4. The total value of all plants was R1694 (US$ 269) per household per year, or approximately R4200 (US$ 667) per hectare of home garden per year. Wild plants represented 31% of the value of all plants grown on residential plots, relative to the 69% for domesticated crops (including fruit trees). Approximately 72% of the total value of all plant products was consumed by the household, and the remaining 28% was sold.This revised version was published online in November 2005 with corrections to the Cover Date.  相似文献

We undertook ethnobotanical study of forage/fodder plant species used by the Afar and Oromo (Kereyu and lttu) Nations in and around the semi=arid Awash National Park (ANP), Ethiopia. The study aimed at investigating and documenting indigenous knowledge (IK) on forage/fodder plant species and threats to their survival. Ninety-six in= formants between 20 and 80 years old were selected using prior informa- tion. Data were collected using semi-structured interview, guided field wail discussion and field observation. Preference ranking, Jaccard's coefficient of similarity and priority ranking were used for data analysis. One hundred twenty-six forage/fodder species of 90 genera and 43 fami- lies were collected in the study area. More than 88% of the species were reported with their vernacular names, where 68% were reported by the Afar Nation and 70% by the Oromo Nation. Family Poaceae was repre- sented by 25 species (20%), followed by Fabaceae 18 (14%). Preference ranking for the most preferred forage grasses as perceived by key informants revealed that Chrysopogon plumulosus was the most important forage/fodder species. Overgrazing was the major threat in the study area, scoring 22%.  相似文献

Biodiversity in Eastern Madagascar is threatened by slash and burn agriculture, which is resulting in species extinction, land and soil degradation and rural impoverishment. An ethnobotanical study was undertaken to determine the domestication potential of indigenous fruit tree species as components of agroforestry systems. Four major selection criteria were used: nutritional and income needs of the population, diversification of the agroecosystem, and protection of plant and animal diversity. At three sites, Andasibe, Masoala and Ranomafana, in the humid primary forest region of Eastern Madagascar, a total of 150 wild fruit species from 82 genera and 42 families, of which 85% were indigenous and 92% of woody habit, were identified. In contrast to most of the deforested areas in Madagascar, the rural population in these areas possess an intimate knowledge of indigenous plant resources. Most of the indigenous fruits are collected from the forest but for a few species, domestication is initiated by managing naturally established species or by planting individual trees in agricultural fields. Wild fruits supplement the daily diet, substitute for exotic fruits, gain importance during periods of food shortage and are most appreciated by children. Commercialization of wild fruits is mainly undertaken by the poorer section of the population. Gender related differences in knowledge and preferences on species were identified and related to the respective household responsibilities. A list of the 26 priority species was established based on the preferences of children, women and men at the three sites. Local, fruit-eating lemur species are also highly dependent on indigenous fruit trees and are crucial for successful regeneration of forest vegetation. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

Species diversity and ethno-medicinal usage of 39 species of invasive plants were explored in and around two protected areas, Khadimnagar National Park (KNP) and Rema-Kalenga Wildlife Sanctu- ary (RKWS), of northeastern Bangladesh,. Status of invasive plants were investigated in 60 sample plots with 5 different habitat types, including forest, roadside, homestead, fallow land and others (ponds, canals, water logged areas, agricultural land, etc.). Data about the usage of invasive plants in traditional health care were collected through interviewing 110 households. Among the five habitat types, fallow land (28 species) pos- sessed the highest number of species, followed by roadside (25 species), forest (23 species), homestead (22 species) and others (13 species). Based on the survey, invasive plants of study areas were also categorized into five degrees of invasiveness e.g., naturalized, introduced, possibly invasive, moderately invasive and highly invasive. Additionally, there is the linear trend between degrees of invasiveness and use percentage of invasive plants. Total 39 species of invasive plants belonging to 29 fami- lies were recorded, which are generally used to treat 37 diseases, ranging from simple headache to highly complicated eye and heart diseases. The majority of the species used by the local inhabitants were herbs (16 spe- cies), followed by some shrubs (11 species), climbers (5 species), trees (5 species) and grasses (2 species). The use percentage of aboveground plant parts were higher (70.58%) than that of underground plant parts (16.18%).  相似文献

Amazonian plant management is perhaps nowhere as intense as in homegardens and swiddens. A quantitative ethnobotanical study was conducted in Indigenous Territory and National Park Isiboro-Sécure, Bolivia, to investigate plant use and management in homegardens and swiddens by local Yuracaré and Trinitario ethnic groups. Ethnobotanical data of plants were obtained from 11 Yuracaré and 11 Trinitario participants through semistructured interviews. A total of 151 different cultivated or tolerated species was recorded, accounting for 21% of all inventoried plants considered useful to local Yuracarés and Trinitarios. The local use value of managed plants is almost twice that of wild plants. Managed plants score particularly higher than wild plants for medicinal, food and material applications. Most managed plants are herbs, followed by trees and shrubs. Nevertheless, managed trees have significantly higher overall use values than all other life forms. Managed trees tend to be particularly more appreciated as sources of food and materials, whereas herbaceous plants generally have a higher therapeutic value. Our results support observations made in literature that moderately humanized landscapes, and homegardens and swiddens in particular, are an important source of food and healing for forest people. Although people generally start managing plants in homegardens and swiddens because of their perceived usefulness, they are also favourable locations to experiment with the usefulness of (managed or wild) plants prevailing there. This particularly accounts for medicinal plants and it is argued that the use of managed plants in traditional medicine relates to (1) the high intensity of contact with theses species, and (2) their chemical defence strategy. To conclude, a number of policy recommendations are presented.  相似文献

The study was undertaken in three districts of Amhara region to assess the extent and purpose of integration of wild indigenous woody perennial fruit bearing species in the agricultural landscapes, appraise their species composition and diversity and identify factors holding back farm integration. Data were gathered through interviews administered to 90 randomly chosen household heads, and fruit trees census in each and every plot of the informants. Species diversity was found to be low and vary by farm, land use type and site. Altogether 17 species were recorded in the agricultural settings. Species retention in the different land use types appears to be governed by species relative importance and compatibility with annual crops, where farm edges recorded a higher ethno-ecological importance score. Nevertheless, as it stands now fruit bearing species are retained primarily for non-fruit utilities. Free availability, land shortage, slope and altitude as well as disgrace feelings are among the major factors holding back farm integration and diversity of indigenous species for fruit production. Should they are additionally exploited for their fruits proper, there is a critical need to raise recognition and awareness at the rural grassroots level and instill knowledge about the food values, and assist in appropriate tree management techniques and inter-cropping regimes as well as accessing markets.  相似文献

Documentation of ethnomedicinal use of plants has been considered a high priority to support the discovery of new drugs to benefit mankind. This paper deals with the field observations recorded on the use of medicinal plants in traditional health care systems of the Tharus of three Villages of Nawalparasi district of central Nepal. The Tharus are isolated forest dwellers who have lived harmoniously with nature over the centuries and accumulated a vast knowledge of plant use to cure various ailments. First-hand information on the ethnomedicinal uses of 110 plants species belonging to 52 families were documented from the study. These plant species are used by the Tharus to treat ailments ranging from fever and headache to cough and cold, rheumatic pain and fracture to urinary tract infection and menstrual disorders. The scientific names of these plants are presented in tabular format according to alphabetic order, family, parts used, medicine preparation process and use and method of application. Increasing accessibility of modern health care facilities, low recognition of traditional healers and decreasing interest amongst the young generation has resulted in declining trends in the use of traditional medicine among the Tharus. Thus, the documentation of such knowledge is an important step for preservation of traditional knowledge, conservation and management of valuable plant resources and commercialization of ethnomedicines.  相似文献
