The objectives of this study were to characterise the body of knowledge of wild edible plants possessed by teachersworking in rural and urban areas of arid Patagonia. We also evaluated whether the different age classes of teachers have different likelihoods of citing plants in relation to different aspects of their ecological and socio-cultural attributes. Study subjects were 85 female and 14 male 21 to 66 year-old teachers from Dolavon, Gaiman, Trelew, Rawson and Puerto Madryn, who were interviewed using written free listing questionnaires. A multinomial logistic regression model including different age classes of teachers as a dependent variable, and as independent categorical variables: informant gender, plant life form, ubiquity, presence of medicinal use and global socio-economic importance of the cited plant species, yielded results which were both significant and predictive. A total of 96 native and exotic species were cited, including plants growing in the immediate surroundings (39 spp.), those from more distant forest environments (9 spp.) and cultivated plants (48 spp.). Most cited species are cosmopolitan herbs which have edible aerial parts, play a significant role in the past and present global economy, have additional medicinal uses, and are associated with the nearest landscapes. The importance of the complementary medicinal use of the edible plants cited, their significance in the global market, and their local ubiquity did not seemto vary between age categories of teachers. The traditional ecological knowledge possessed by Patagonian teachers seems to consist of a body of knowledge constructed on a foundation of accumulated experience of the local environment and the cultural values that have prevailed since the initiation of formal education. This work shows the importance of logistic models as a tool in the study of traditional knowledge, given that they reflect, in a predictive way, the variation existing in different subgroups in relation to a complex network of multiple factors. In addition, in this work we emphasise the importance of considering the cultural capital of the teachers themselves as a highly significant dimension, which can have a direct influence on the schools in terms of education and learning about Nature. ©
