Seed regeneration in native forests of Nothofagus antarctica under silvopastoral use in Southern Patagonia, Argentina
The aim of the present study was to evaluate the effect of silvopastoral use in two pure stands of Nothofagus antarctica (ñire, ñirre) growing at two site qualities on the regeneration cycle from production and quality of seeds, and the establishment and mortality of seedling in Southern Patagonia (...
