Burning monkey-puzzle: Native fire ecology and forest management in northern Patagonia

Abstract

This article outlines the ecological and ethnobotanical characteristics of the monkey-puzzle tree (Araucariaaraucana), a long-lived conifer of great importance to the indigenous population living in and around its range in the southern Andes. The article also considers the pre-Columbian and historical use of indigenous fire technology. Conclusive evidence of indigenous burning is unavailable. However, our knowledge of native fire ecology elsewhere and our understanding of monkey-puzzle's ecological response to fire suggest that indigenous people probably burned in the past to facilitate the growth of monkey-puzzle trees relative to other species. The obstacles to recovering and redeploying a defunct fire-based production strategy include the vulnerable condition of monkey-puzzle stands after decades of intense logging and burning (by non-indigenous settlers), inadequate access to land and resources by the region's indigenous inhabitants, livestock pressure, depletion of game animals that were once hunted with fire, and reluctance by indigenous people to embrace old production strategies that have been supplanted by new ones based on domesticated animals and crop cultivation. Prescribed burns in selected areas offer an effective way to assess the feasibility of indigenous burning as an alternative to more conventional development initiatives.
