The ancestral tradition of gathering nontimber products in the Andean forests of Patagonia seems to be on the verge of disappearing. Edible wild plant knowledge and differential patterns of use have been compared in two populations of different economic and cultural backgrounds—a small rural Mapuche community (Rams), and an outlying population (El Frutillar). The first is located in an herbaceous steppe far from the nearest Andean forest while the second is located outside the town of Bariloche, near the forests of Nahuel Huapi National Park. Semistructured interviews and related ecological variables were compared in both communities. In the past, both communities utilized nontimber forest products from the Andean Temperate forests. However, today, cost and benefit trade-offs appear to affect when and what edible resources are collected. The people from El Frutillar gather fewer wild plants in spite of the high plant abundance and the notorious food scarcity they suffer. The Mapuche people use more nutritious resources, more native species, spend longer traveling to the gathering site, and longer handling time preparing edible plants.  相似文献

The multiple use of distinct ecological environments in the search for wild resources has been practiced since ancestral times in aboriginal communities inhabiting northwestern Patagonia. This paper examines the actual use and knowledge of wild edible plants in a Mapuche community presently settled in one of the most arid areas of Patagonia, far from the temperate forests where their ancestors used to live. The difference between knowledge of and use of wild plants is analyzed emphasizing that these differences could contribute to the understanding of eroding processes believed to be occurring in the community. These objectives are studied quantitatively by utilizing ethnobotanical indices, partially derived from ecological theory. Our results indicate that the Paineo dwellers still utilize multiple ecological gathering environments and have thorough plant knowledge of both native and exotic species. The Andean forest, more than 50km away from this community, is the environment from which the Paineo dwellers know the greatest total richness and the highest diversity of wild edible plants, followed by the Monte–Steppe species and lastly, those growing around their homes. The transmission of wild edible plant knowledge in the Paineo community diminishes with age, and the forest plants are the most vulnerable to loss. Our results have shown that the knowledge and consumption of wild edible plants follows a pattern according to ecological conditions of the gathering environments, as well as the cultural heritage of the Paineo people.  相似文献

We have compared edible plant richness, diversity and differential patterns of use in two Mapuche communities of Argentina. The populations of Rams and Cayulef are located in a herbaceous steppe, far from the temperate forests of northwestern Patagonia where their ancestors lived in the past. Ecological concepts and methods, such as diversity indices, niche breadth and optimal foraging theory have been used in this comparative study. Our results indicate that the diversity of wild plants used in Rams and Cayulef is associated with the variety of gathering environments they visit. When comparing diversity indices among the three environments within each community, in Cayulef we found the highest diversity indices for steppe species and the lowest for forest plants. In contrast, in Rams the niche breadth is similar in all environments, indicating an ample exploration and use of edible wild plants. Cost and benefit trade-offs seem to be considered in both communities when edible plants are collected. Nevertheless, we found that the people from Rams not only utilize a greater richness of wild plants than the Cayulef people, but also use more nutritious resources, spend more time traveling to the gathering sites and a longer handling time in preparing these edible plants. This study has quantitatively shown that the restricted access to Pehuen forest (Araucaria araucana) is the main factor which seems to limit wild plant diversity used in these Mapuche communities.  相似文献

Edible Wild Plant Use in a Mapuche Community of Northwestern Patagonia   总被引:3,自引:0,他引:3  
Mapuche Indians have a long tradition of using edible wild resources. The people of Rams (Neuquén, Argentina) consider themselves descendants of the Pehuenches, an Indian group that once inhabited the Pehuén forest region. They now live in the steppe, far away from the forest. Our primary interests are how this community uses edible resources and in analyzing which plants are still utilized. We conducted an ethnobotanical study, which consisted in interviewing several Mapuche families and collecting plants with their help. Ecological variables of plant use, such as search cost, handling time, and nutritional content, were analyzed from the perspective of Optimal Foraging Theory. Our results indicate that the Rams inhabitants have a thorough understanding of their environment, expressed in a selective gathering of wild resources. Cost and benefit trade-offs seem to be considered when edible plants are collected.  相似文献

Cattle transhumance has been practiced since colonial times in Mapuche communities of northwestern Patagonia, which travelled seasonally along the Andean valleys from arid lands towards temperate forests. In this study, we analyzed how this migratory practice affects the abundance and variety of wild edible plants utilized by the Mapuche community of Paineo. Patterns of use for those who practice transhumance were compared with those who do not utilizing ecological variables. Gender and age were also evaluated. The Paineo people collect wild plants in 3 different gathering sites: the A. araucana forest, the Travesía, and their dwelling surroundings. However, those who practice summer transhumance utilize a more diverse variety and a tan greater quantity of wild edible forest plants than those who do not. Moreover, the nutritional value of plants collected by transhumants is greater than those used by non-transhumants. Men practice summer cattle transhumance in a greater proportion than do women and consume significantly more wild edible plants. In contrast, plants from their dwellings and from the Travesía are used in a similar way by both sexes. It was observed that the elderly do not presently participate in transhumance. Our results illustrate a change in wild plant knowledge influenced by the transformation of the summer transhumance pattern.  相似文献

We investigated the use of plants collected in the wild by a small farming community in Central Panama to document the importance of noncultivated plants by tropical, nonforest-dwelling, nonindigenous people. We visited the community to observe what wood was used to build houses and interviewed local people about medicinal and edible plants collected in the wild state. The community reported use of 119 noncultivated plant species, including 108 tree species, three shrubs, two herbs, four lianas, and two vines. The majority (71) of the species were used for building homes. Other products built with wood collected in the wild were diverse kinds of tools, containers, cages, and fences. The second most important use of wild plants, in terms of number of species, was firewood, for which 40 species were mentioned by the community. Other uses included fruit for human consumption (20 species). Most of the species (82 of 119) were collected in secondary forests near the community, whereas another large group (47 species) were collected in mature forest. Fewer species were harvested in shrubby regrowth or from isolated trees in farm land. Nearly all the species (111 of 119) were native to the area, and never cultivated locally, but 15 species were considered especially valuable, and were often protected when found as juveniles. Only six of the species are commonly used in reforestation programs in Panama. We conclude that even hispanic communities in tropical Latin America, living outside the forest, with no Amerindian inhabitants, make frequent use of the great diversity of trees native to the region.  相似文献

In the present study we analyzed medicinal and edible plant utilization in Cuyin Manzano, a small rural population located near the Andean forests of Argentina. We also studied where and when plant knowledge was learned, who the principal transmitters were, and how people were taught. The participants were interviewed individually and at random, by means of a semi-structured questionnaire. Interviews were carried out in 16 families in order to examine the present use of wild plants. The inhabitants of Cuyin Manzano cited 87 plants: 63 medicinal and 24 edible species. They mentioned on average 31 ± 10 species per person. Similar patterns of plant use were found in young and old people alike, irrespective of gender. Learning about useful plants took place at an early age as a result of family tradition. This local knowledge is acquired and taught “by doing,” and is mostly transmitted vertically through family dissemination. Wild plant learning implies the acquisition of plants' physical and functional features as well as their environmental characteristics.  相似文献

Southern Chile experienced serious deforestation during the past century and it is projected that by the year 2025 Chile will be devoid of native forests. One of the most important endemic tree species of the country and at the same time one of the most endangered ones is Araucaria araucana (Mol.) C. Koch, the monkey-puzzle tree. It grows in the Andes Mountains, homeland of the indigenous Mapuche Pewenche people who depend on this tree. This paper is based on participatory field research with a Mapuche Pewenche community in the southern Chilean Andes on their ecological knowledge, values, use and management of the Araucaria araucana forest. It attempts to reveal how indigenous people and their knowledge contribute to the sustainable management of these forests. The paper (1) illustrates the complexity of indigenous ecological knowledge of Araucaria araucana and its efficacy in native forest management, (2) explores the link between the conservation and use of biodiversity by the indigenous people, and (3) provides answers relevant to native forest management and conservation strategies ex-situ and in-situ incorporating indigenous and scientific knowledge, thus providing a contribution towards integrated natural resource management.  相似文献

The edible wild plants are greatly valued throughout the Himalayan region and serve as an important source of food for indigenous communities. This paper describes the botanical richness, elevational distribution and dietary use of the edible wild plant resources from the Sikkim Himalaya (Eastern Himalaya), many with promising potential. A total of 190 wild plant species have been screened from the Sikkim Himalaya, this derived from 143 genera and 78 families and accounting for nearly 15% of total edible wild plants resources of India. Of the total, 65% were edible for their fruits, 22% for leaves/shoots, 7% for flowers and 3% for roots/ rhizomes. Nearly 91 wild edible species were recorded from low-hills, 70 from mid-hills and 28 species from high-hill areas. Within Sikkim state, the North and East districts represent maximum diversity of edible wild plants due to the wilderness and inaccessibility to most of the habitats. An average rural family annually consumes nearly 8 types of edible wild plants, and a few species provide over five meals in a season. Selected plants also form a source of earning to a few families that sell them in local markets. It is suggested that the high diversity of edible plants needs to be conserved for future use. Some species may be grown in traditional agroforestry systems and on marginal lands of otherwise low agricultural value. Such measures may help protect wild plant resources in their natural habitats.  相似文献

Wild edible plants, ecological foodstuffs obtained from forest ecosystems, grow in natural fields, and their productivity depends on their response to harvesting by humans. Addressing exactly how wild edible plants respond to harvesting is critical because this knowledge will provide insights into how to obtain effective and sustainable ecosystem services from these plants. We focused on bamboo shoots of Sasa kurilensis, a popular wild edible plant in Japan. We examined the effects of harvesting on bamboo shoot productivity by conducting an experimental manipulation of bamboo shoot harvesting. Twenty experimental plots were prepared in the Teshio Experimental Forest of Hokkaido University and were assigned into two groups: a harvest treatment, in which newly emerged edible bamboo shoots were harvested (n = 10); and a control treatment, in which bamboo shoots were maintained without harvesting (n = 10). In the first year of harvesting (2013), bamboo shoot productivities were examined twice; i.e., the productivity one day after harvesting and the subsequent post-harvest productivity (2–46 days after harvesting), and we observed no difference in productivity between treatments. This means that there was no difference in original bamboo shoot productivity between treatments, and that harvesting did not influence productivity in the initial year. In contrast, in the following year (2014), the number of bamboo shoots in the harvested plots was 2.4-fold greater than in the control plots. These results indicate that over-compensatory growth occurred in the harvested plots in the year following harvesting. Whereas previous research has emphasized the negative impact of harvesting, this study provides the first experimental evidence that harvesting can enhance the productivity of a wild edible plant. This suggests that exploiting compensatory growth, which really amounts to less of a decline in productivity, may be s a key for the effective use of wild edible plants.  相似文献

Background

Traditional markets outstandingly contribute to conservation of biocultural diversity, social relations, and cultural values. These markets reflect life strategies and forms people of a region interact with their biodiversity and territories, as well as traditional ecological knowledge and management practices. To understand the factors motivating plant and mushroom management, we analyzed the resources cultural and economic values, their role in people’s subsistence, and the relation of these values with the resources spatial and temporal availability. Our study based on the supposition that traditional markets are settings of interchange of resources with the highest importance for people’s life in a region. Also, that the cultural, economic, and ecological factors influence values of the resources, and the demand on them determine pressures on the most valuable resources which, when scarce, motivate management innovation, otherwise become extinct.

Methods

We documented cultural, economic, and ecological aspects, as well as management techniques of wild and weedy plants and mushrooms interchanged in three traditional markets of the Pátzcuaro Lake region, in central-western Mexico. For doing that, from February 2015 to March 2018, we conducted 175 visits to markets and 89 semi-structured interviews to producers, gatherers, and sellers of wild and weedy plants and mushrooms. Based on participant observation and interviews, we identified variables related to culture, economic, and ecological aspects, as well as management regimes of resources and management systems, which were documented and used as indicators for quantitative analyses. Through principal components analyses (PCA), we determined the indexes of cultural and economic importance (ICEI), management intensity (IMI), and ecological risk (IR) of the resources studied. For conducting that, we classified plant and mushroom species according to their cultural, economic, ecological, and technological indicators, respectively. The score of the first principal component was considered as the index for each group of variables, respectively. To identify relations between cultural importance and risk, we performed linear regression analyses between ICEI and IR indexes.

Results

We recorded 57 species of wild and weedy plants used as food, medicine, and ornamental, and 17 species of edible mushrooms. The variables with the highest weight in the ICEI are related to the need of a resource according to people, its recognizing, the number of communities and markets offering it in markets, its explicit preference expressed by people, the effort invested in obtaining it, and the form it is interchanged. Gathering is practiced in all mushrooms and wild and weedy plants from forests and agricultural areas; 11 species in addition receive 1 or more forms of management (enhancing, selective let standing, propagation through seeds or vegetative parts, transplantation, and/or protection). The management intensity and complexity are explained by variables related to management practices and systems. Plants receiving selective management have the higher management intensity. Silvicultural management (in situ management in forests) was recorded in all species of mushrooms, as well as in more than 80% of medicinal, ceremonial and ornamental plants, and in more than 50% of the edible plants. In agricultural systems, people manage more than 90% of the edible plants recorded to be under a management regime, 25% of the managed medicinal plants, and 30.7% of the managed ceremonial and ornamental plants. In homegardens, people manage 41.6% of the medicinal plants recorded and 26.6% of the edible plants, to have them available near home. Nearly 63% of the species interchanged in the markets studied are gathered in forests without any other management form. In this group are included all mushroom species, 61.5% of ceremonial/ornamental plants, 50% of medicinal, and 33.3% of edible plants. The linear regression between ICEI an IER is significantly negative for edible species with high management intensity R2?=?0.505 (p?=?0.0316), because of their management. But in medicinal and ornamental plants, the risk is high if the cultural importance increases, even when management practices like transplanting and propagation in homegardens are carried out.

Conclusions

Traditional markets are settings of interchange of products, knowledge, and experiences, where the ongoing factors and processes motivating management innovation can be identified and documented. This approach allows documenting processes occurring at regional level but would be benefited from deeper studies at local level in communities.

Background

Despite being an ancient practice that satisfies basic human needs, the use of wild edible plants tends to be forgotten along with associated knowledge in rural communities. The objective of this work is to analyze existing relationships between knowledge, use, and management of native wild edible plants and socioeconomic factors such as age, gender, family income, individual income, past occupation and current occupation.

Methods

The field work took place between 2009 and 2010 in the community of Carão, Altinho municipality, in the state of Pernambuco in northeastern Brazil. We conducted semi-structured interviews with 39 members of the community regarding knowledge, use and management of 14 native wild edible plants from the Caatinga region, corresponding to 12 vegetable species. In parallel, we documented the socioeconomic aspects of the interviewed population (age, gender, family income, individual income, past occupation and current occupation).

Results

Knowledge about edible plants was related to age but not to current occupation or use. Current use was not associated with age, gender or occupation. The association between age and past use may indicate abandonment of these resources.

Conclusion

Because conservation of the species is not endangered by their use but by deforestation of the ecosystems in which these plants grow, we suggest that the promotion and consumption of the plants by community members is convenient and thereby stimulates the appropriation and consequent protection of the ecosystem. To promote consumption of these plants, it is important to begin by teaching people about plant species that can be used for their alimentation, disproving existing myths about plant use, and encouraging diversification of use by motivating the invention of new preparation methods. An example of how this can be achieved is through events like the “Preserves Festival”.

An ethnobotanical study was conducted through interview and field work during 20103-20117 to determine the wild medicine food plants used by the local people of Xishuangbanna, southwest Yunnan, China. All information provided on the uses of medicine food plants by local communities was documented. In addition, the disk diffusion method was used to test the antibacterial activities of some plants. A total of 95 plant species belonging to 43 families were reported as medicine food plants, with Solanaceae (6 species) and Lamiaceae (6 species) being the most represented families. Most plants used were herbs (495%), of which 20 were screened for antibacterial activities. Baphicacanthus cusia and Solanum spirale showed moderate antibacterial activities against Staphylococcus aureus. Our interviews revealed that in the study area wild plants are still commonly used for food and medicinal purposes by people in their daily lives. However, there is a gradual loss of traditional knowledge about these plants due to a decline in inter generational transmission of knowledge. Loss of this precious knowledge is a major concern.  相似文献

This paper presents data on marketing, value addition and management concerns of the wild edible plants of the Sikkim Himalaya. At least 23 weekly markets, locally called ‘ Hats ’, have been identified in the state, and three markets, viz. Gangtok, Namchi and Singtam, were studied in detail, for one year, with reference to the availability, quantity sold and retailers involved with the marketing of wild edible species. A total of 44 wild edible species have been recorded to be sold annually in the three markets. Among all the species,Spondias axillaris was sold in highest quantity and more retailers were involved in its business than for any other wild edible plant. Other important species wereMachilus edulis, Diplazium esculentum, Eleagnus latifolia,Dendrocalamus hamiltonii, Agaricus and Baccaurea sapida. The rural economics of wild edible plants is estimated to be some 140 tons per annum, and the prices for various species have increased over the years. At Gangtok, prices increased 3 to 6 times from 1981 to 1996–1997. Analysis of the field data showed that the wild edible plants were an important source of income to the plant dwellers and subsistence for farm families. Value addition was done to a few wild edible species, and cost-benefit analysis showed that the income from the fruits could be increased by at least 3–5 times after making pickles, squash and jam. It was recorded that plant dwellers have open access for the collection of these plant resources, which often leads to their over exploitation, and the local state government at present lacks policies and strategies for protecting and promoting wild edible plants in any of its programs. It is suggested that suitable conservation practices and policies need to be formulated to conserve these plants in the wild habitats within the state.  相似文献

In a Mapuche community situated in the sub-antarctic forest of the northwest of Argentine Patagonia, analysis was carried out on forest environmental perception and its relation to the resilience of the body of traditional botanical knowledge regarding medicinal plants. Data was obtained on the ethno-classification and differential use of the forest gathering environment with respect to its practical and cultural value. Semi-structured interviews were carried out with 30 randomly chosen inhabitants, and the data were analysed using qualitative methods and non-parametric statistics. Most citations (64.5%) were of species gathered in Nothofagus antarctica forest, 26.2% were of species from N. pumilio forest, and 20.3% referred to species from a mixed forest, with N. dombeyi. The forests studied have low values for similarity in terms of medicinal species richness, indicating a unique offer of therapeutic resources in each one. The use of the different forest types seems to be associated with the search for therapeutic resources for specific ailments. However, the redundancy of functions of species in each forest type can offer alternative remedies, which provides plant conservation, security and the possibility of reorganisation of their traditional medicinal knowledge. This case study showed the importance of considering folk systems and the role that this knowledge has played in plant resource management and forest protection. Different forests are used and valued differentially, not only with regard to usefulness but also in symbolic-religious terms, and together they fulfil a cushioning function, protecting holistically traditional botanical knowledge, people’s health and forests. It is of great importance, therefore, that conservation policies favouring environmental heterogeneity are implemented, and that local inhabitants participate in the development of management plans.  相似文献
