Knowledge and use of wild edible plants in rural communities along Paraguay River, Pantanal, Brazil Ieda Maria Bortolotto1,4*, Maria Christina de Mello Amorozo2, Germano Guarim Neto3, Jens Oldeland4 and Geraldo Alves Damasceno-Junior1,4 Abstract Background: Wild plants are used as food for human populations where people still depend on natural resources to survive. This study aimed at identifying wild plants and edible uses known in four rural communities of the Pantanal-Brazil, estimating the use value and understanding how distance to the urban areas, gender, age and number of different environments available in the vicinity can influence the knowledge and use of these plants by local people. Methods: Data on edible plants with known uses by communities were obtained through semi-structured interviews. A form with standardized information was used for all communities in order to obtain comparable data for analysis. For the quantitative analysis of the factors that could influence the number of species known by the population, a generalized linear model (GLM) was conducted using a negative binomial distribution as the data consisted of counts (number of citations). Results: A total of 54 wild species were identified with food uses, included in 44 genera and 30 families of angiosperms. Besides food use, the species are also known as medicine, bait, construction, technology and other. The species with the highest use value was Acrocomia aculeata. Older people, aged more than 60 years, and those living in more remote communities farther from cities know more wild edible plants. Statistical analysis showed no difference regarding gender or number of vegetation types available in the vicinity and the number of plants known by locals. Conclusion: This study indicated more knowledge retained in communities more distant from the urban area, indifference in distribution of knowledge between genders and the higher cultural competence of elderly people in respect to knowledge of wild edible botanicals.

Background Hundreds of wild plant species are used as food for human populations where people still depend on natural resources to survive. Ethnobotanical studies have been carried out to identify these species and their popular uses motivated by a strong interest in edible plants that are closely related to cultivated species [1] and which may offer greater global food security [2]. Furthermore, much of this knowledge is * Correspondence: [email protected] 1 Laboratory of Botany, Center of Biological Sciences and Health, Federal University of Mato Grosso do Su
