Development of an Araucaria araucana Beer-like Beverage: Process and Product [PDF]

Fermentation, 2021
The seed from the Araucaria araucana (in Spanish, piñon) tree, native to Chile and Argentina, is sold mainly as raw seed. Engineering a process to add value to piñon has the potential to positively impact local indigenous communities with very little ecological impact because it is routinely harvested in the wild.

An ecophysiographic approach for Araucaria araucana regeneration management [PDF]

Ciencia e investigación agraria, 2012
Chilean temperate forests are dominated by Nothofagus and Araucaria araucana species. Despite A. araucana not being at imminent risk of extinction, its cultural value and the associated environmental services and landscape goods have an important role for the conservation of this native forest. In some areas, the future conservation of A. araucana is a

Poblaciones de araucaria enana (Araucaria araucana) en la Cordillera de Nahuelbuta, Chile [PDF]

Bosque (Valdivia), 2008
Araucaria araucana (araucaria o pehuen) desarrolla normalmente en su habitat natural un crecimiento arboreo con altura > 20 m. Sin embargo, en 1984, en la cima de la Cordillera de Nahuelbuta se encontraron dos poblaciones enanas. En este trabajo se caracterizo la estructura, composicion y edades de ambas poblaciones de A.

Fire history in the Araucaria araucana forests of Argentina: human and climate influences [PDF]

International Journal of Wildland Fire, 2012
Little is known about drivers and trends of historic fire regimes in the Araucaria araucana forests of south-western Argentina. Fire history in these forests was reconstructed by the analysis of 246 fire-scarred partial cross-sections from this fire-resistant tree collected at 10 sites in Neuquén, northern Patagonia.
