Summer Cattle Transhumance and Wild Edible Plant Gathering in a Mapuche Community of Northwestern Patagonia

Cattle transhumance has been practiced since colonial times in Mapuche communities of northwestern Patagonia, which travelled seasonally along the Andean valleys from arid lands towards temperate forests. In this study, we analyzed how this migratory practice affects the abundance and variety of wild edible plants utilized by the Mapuche community of Paineo. Patterns of use for those who practice transhumance were compared with those who do not utilizing ecological variables. Gender and age were also evaluated. The Paineo people collect wild plants in 3 different gathering sites: the A. araucana forest, the Travesía, and their dwelling surroundings. However, those who practice summer transhumance utilize a more diverse variety and a tan greater quantity of wild edible forest plants than those who do not. Moreover, the nutritional value of plants collected by transhumants is greater than those used by non-transhumants. Men practice summer cattle transhumance in a greater proportion than do women and consume significantly more wild edible plants. In contrast, plants from their dwellings and from the Travesía are used in a similar way by both sexes. It was observed that the elderly do not presently participate in transhumance. Our results illustrate a change in wild plant knowledge influenced by the transformation of the summer transhumance pattern.
