Araucaria araucana

Araucaria araucana is an evergreen conifer native to the Andes of Chile and Argentina. Its whorled branches, sharply pointed leaves, and large edible seeds distinguish it from most familiar conifers.

Conifer: A cone-bearing gymnosperm tree or shrub, usually with needle-like or scale-like leaves. Araucaria araucana is a conifer, though its broad, rigid leaves differ from the familiar needles of pines.
Wind pollination: The transfer of pollen between plants by air currents rather than animal pollinators. Wind carries pollen from male cones to female cones.
Pehuén: The Mapuche name for Araucaria araucana and, in related usage, its edible seed. The tree and its seeds are central to the identity and subsistence traditions of the Pehuenche.
Andes: A mountain range running along the western edge of South America. Araucaria araucana is native to high-elevation forests of the southern Andes.
IUCN Red List: A global assessment system that classifies species’ extinction risk. The species’ conservation status is assessed against this international framework.
Gymnosperm: A seed-producing plant whose seeds are not enclosed within an ovary or fruit. Its seeds develop without the protective fruit characteristic of flowering plants.
Seed dispersal: The movement of seeds away from the parent plant before germination. Large seeds can be carried or cached by animals, helping seedlings establish away from parent trees.
Pehuenche: An Indigenous people of the Andes whose traditional territory includes forests of Araucaria araucana. Pehuenche communities have long gathered and used the tree’s seeds as food.
Chile: A country on the western coast of South America, extending from the Atacama Desert to Patagonia. Much of the tree’s natural range lies in the Andes of south-central Chile.
Wildfire: An uncontrolled fire that burns vegetation and natural landscapes. Severe fires can damage slow-growing trees and alter their Andean forest habitat.
