Forestación peridoméstica en Patagonia y conocimiento ecológico tradicional: un estudio de caso

The Patagonian steppe is a cultural landscape which is constantly being recreated by man. In this case study, peridomestic forestation of tree species was analysed in a small community, including the richness of plants used and the reasons behind their choice. In the Mapuche population of Pilkiniyeu del Limay (Rio Negro) free and semi-structured interviews were carried out with 28 interviewees. The data was analysed using both uni- and multivariate methods. Results indicate that nine exotic species are used. These forested areas, used for meetings and recreation, provide useful living space and are of great social importance. The principal motivation behind this forestation is the need for materials for building fences (96%), to provide shelter from the elements (86%), firewood (43%), and cattle fodder (11%). The MSD revealed a shared value system with respect to the forestation. The traditional ecological knowledge that people use in the selection and use of firewood species does not seem to have an influence on choices made when planting trees around their homes. This could indicate that forestation is a general practice deeply rooted and influenced by the oblique transmission carried out by external agriculture agents who visit and offer help to this community.
