| Popis: | The sustainable use of ñire forests requires knowledge of its dynamics and management to maintain long-term main forest ecosystem services. The aim of this work was to develop a Structural?Functional State and Transition Model (SFSTM) for ñire forests in southern Patagonia. For this, provincial inventory information was analyzed together with information from permanent PEBANPA plots (Plots of Ecology and Biodiversity, Natural Environments in Southern Patagonia) and studies of ecology and ecophysiology in ñire forests which described plant communities on these ecological sites and the history of natural disturbances. Seven states and 10 negative transitions were described, as well the factors that trigger transitions and their associated levels of grazing, fire and intense logging. Mature forests with low grazing, no extractive activity and complete canopy cover (> 70%) corresponds to the reference state or condition of greater integrity, and grassland or murtillar (dominance of Empetrum rubrum) with forest loss is considered the most degraded state. Negative transitions determine the threshold crossings associated with the reduction or loss of resilience to the previous or original state. The development of E&TM allows for early warnings of deterioration and is a tool to achieve more productive and environmental value. Fil: Peri, Pablo Luis.
