Resumen:
Nothofagus antarctica native forests in Patagonia that cover 751.643 ha are being used mainly for cattle
grazing (70% of the total area), firewood extraction, tourism and recreation activities. Silvopastoral
systems in these forests, that combine trees and grasslands or pastures under grazing (mainly sheep and
cattle production) in the same unit of land, would be an economical, ecological and social productive
alternative in southern Patagonia. The sustainable management of these forests has been legally
declared as an objective. In this context, long-term research to account for the ecological and economic
interactions (positive and/or negative) between the woody, non-woody and animal components of these
systems had been established. Data on above- and below biomass, carbon and nutrient accumulation in
different tree components, dry matter production and quality of pastures, wood production from thinning
schedules, animal performance (stocking rates, live weight gains) and regeneration have been evaluated
to determine the impact of silvopastoral system practices. However, research on sheep and cattle
production at farm level over a year, the improve of primary and secondary timber industry that
incorporate value to the harvested wood, and further studies that incorporate the impact on landscape
and fauna connectivity at regional level, are needed. Integrated economical information and social
aspects of silvopastoral systems in the region also are important to be developed.
