Small trails, great knowledge: local ecological knowledge shared by children and teenagers of a rural school in Santiago del Estero, Argentina.

Deforestation and forests fragmentation in Argentina and particularly in Santiago del Estero have favored the loss of biodiversity in recent decades. Ethnobiological studies in the province have shown the presence of peasant families in relict of dry forests, who subsist through multiple use strategy (MUS). As it is necessary to develop conservation strategies that include local knowledge and recognize children and adolescents as key players, we conducted a study on the local botanical knowledge of children and adolescents, inquiring about how many and which uses of plant species they know. Field ethnobotanic techniques were used, among them ludic techniques and participative preparation of a territorial map. Children and adolescents recognized 36 plant species. Three principal microenvironments, tours and spaces that function as meeting places outside the households were identified. Finally, a discussion on the inclusion of knowledge of children in school settings is presented, to strengthen a process of teaching and learning, and an education that fosters the conservation of biocultural diversity.
