    This article focuses on the use and the vocabulary of 323 specimens representing 52 species woody species that were collected from three ethnosocio-linguistic groups (Shi, Tembo and Pygmies) living in the ecological corridor of Kahuzi -Biega National Park (KBNP). This area consists of a transitional forest between the vegetation of the plains and the mountains. The study has shown that the food and, pharmacological knowledge are almost detained by the pygmies. The analyses carried out show that this population takes interest to the forestry species they consider to be useful though they are found in a protected area. The total ethno botanical value of species is not really significantly to different ethno-socio-linguistic group to another (p-value = 0.514; F = 1.08 and df = 3). The Kruskal-Wallis test shows that the different organs do not have the same importance for the use of the population. (F = 1.08 and df = 3). The correlation between the ethno botanical use value in relation to the number of species use is significant (RÂČ = 0.084%). Specific vocabularies ethnonymical in Mashi and Kitembo express the same common meanings of species on the formal and semantic plans. These three tribes share several ethnonymical concepts, which could be a symbol indication of the subsistence of a pygmy original language, forgotten to the Bantu languages that have borrowed them. Despite the importance of trees in the hall of the Park, we suggest conservative actions or reforestation could protect

    Unconventional Food Resources. Concepts of ethnobotany, ethnozoology and ethnoecology are defined and their respective development recounted. The geographic frame is afterwards specified: Tropical Africa. Diversity of wild edible vegetable products is illustrated by some examples: cyanobacteria from Chad, mushroom consumption in the Zambezian region and pteridophagy. Upper plants are approached according to six ensembles, namely starchy fruits and seeds, oilseeds and nuts, fleshy fruits, reserve organs, flowers and vegetable species. After recalling the diversity of insects eating at world scale, four orders are briefly presented: coleoptera, isoptera (termites), lepidoptera (mainly caterpillars or campeophagy) and orthoptera. Finally the nutritional input of unconventional foods is underlined as well as the urgent need of their further studies

    Objectif : L’étude ethnobotanique a Ă©tĂ© menĂ©e Ă  l’échelle de la rĂ©gion de Tahoua avec pour objectif la capitalisation des connaissances endogĂšnes des tradipraticiens sur les diffĂ©rentes utilisations des espĂšces vĂ©gĂ©tales vendues dans les marchĂ©s.MĂ©thodologie : Des enquĂȘtes ethnobotaniques Ă  l’aide d’interviews individuelles sur la vente des plantes mĂ©dicinales ont Ă©tĂ© rĂ©alisĂ©es de juin 2017 Ă  avril 2018 auprĂšs de 44 vendeurs et vendeuses installĂ©s dans44 marchĂ©s ruraux hebdomadaires du centre ouest du Niger (RĂ©gion de Tahoua).RĂ©sultats : L’étude a permis de recenser au total, 49 espĂšces rĂ©parties en 40 genres et 28 familles. Sur les 49 espĂšces recensĂ©es dans les marchĂ©s, 28 peuvent ĂȘtre rencontrĂ©es dans la zone d’étude soit 57,14%. Aussi, 15 espĂšces sur ces 28 sont les plus vendues et 18 de plus en plus rares selon les tradipraticiens enquĂȘtĂ©s. Aussi, les rĂ©sultats de l'Ă©tude ont montrĂ© que l’écorce chez les ligneux et la plante entiĂšre chez les herbacĂ©es sont les plus utilisĂ©es. Pour la plupart, les remĂšdes sont prĂ©parĂ©s sous forme de dĂ©coction.Conclusion et applicabilitĂ© des rĂ©sultats : Le recours quasi exclusif des populations locales aux espĂšces vĂ©gĂ©tales mĂ©dicinales dans leurs soins quotidiens accentue la pression sur les ressources mĂ©dicinales pouvant conduire Ă  la disparition de certaines espĂšces. Il est donc nĂ©cessaire et urgent d’envisager la substitution de certaines plantes mĂ©dicinales par la mĂ©decine moderne en vue de sauver les plus vulnĂ©rables.Mots clĂ©s : Capitalisation, plantes mĂ©dicinales, dĂ©coction, Ă©tude ethnobotanique, Tahoua, NigerEthnobotanical study of medicinal plants sold in the markets of central western NigerObjective : This ethnobotanical study was conducted at the Tahoua region with the aim of capitalizing endogenous knowledge of traditional healers on the different uses of plant species sold in markets.Methodology: Ethnobotanical surveys using individual interviews on the sale of medicinal plants were conducted from June 2017 to April 2018 among 44 vendors and vendors in 44 weekly rural markets in west-central Niger (Tahoua Region).Results: The study identified a total of 49 species in 40 genera and 28 families. Of the 49 species identified in the markets, 28 can be found in the study area or 57.14%. Also, 15 of these 28 species are the most sold and 18 are increasingly rare according to the traditional healers surveyed. Also, the results of the study showed that the bark in the woody and the whole plant in the herbaceous are the most used. For the most part, the remedies are prepared as a decoction.Conclusion and application of results: The almost exclusive use of local populations to medicinal plant species in their daily care increases the pressure on medicinal resources that can lead to the disappearance of certain species. It is therefore necessary and urgent to consider the substitution of certain parts of the plant and the planting of exploited species.Keywords: Capitalization, medicinal plants, decoction, ethnobotanical study, Tahoua, Nige

    Southern-Benin has a mosaic of ecological conditions that have contributed to the development of its vast forest heritage. The combination of a number of parameters or indices (use value, diversity index, and equitability and citation frequency) is an effective way of identifying the most important plants for preservation. The objective was to carry out the checklist of the plants used around the classified forests of Ahozon and Lama and the botanical reserve of PobĂš in Southern-Benin, with information on their use, threats and relations between the targeted habitats and the listed plants on the one hand and the knowledge associated with them and the socio-professional characteristics of the populations on the other. The data (user identity, plants used, plant organs collected, uses, plant threats) were collected from 113 individuals interviewed individually during an ethnobotanical study in 20 villages distributed around the three vegetation formations. The results showed that 59 plant species are useful for the populations surrounding the formations. The most important in terms of use value are Zanthoxylum zanthoxyloides (VUT = 7.86), Irvingia gabonensis (VUT = 7.84), Dialium guineense (VUT = 7.69), Khaya senegalensis (VUT = 7.46), Prosopis africana (VUT = 7.06), Ceiba pentandra (VUT = 7.01), and Synsepalum dulcificum (VUT = 6.98). The indices of Diversity and Equitability of the respondents reveal that knowledge on plant species is not homogeneously distributed (ID = 0.430, IE = 0.451 <0.5) and maximum information on species is held by a part of the population. Pruning (40%) is the main source of species threats. Plantation, agrosystems, sensitizing populations on good methods of harvest could help to preserve the main plants useful for the populations of Southern Benin
