Monkey puzzle tree

Scientific

Araucaria araucana (family Araucariaceae) is one of the oldest tree lineages still living — Araucariaceae appears in the fossil record over 200 million years ago, when the family was distributed across both hemispheres. The modern range has retracted to a few relict populations in the Southern Hemisphere: this Chilean / Argentine species, the Australian Araucaria bidwillii (bunya-bunya), and others including [[kauri]] (which is in the related family Araucariaceae).

The species’ distinctive growth form — branches arranged in regular whorls, each whorl bearing arrays of sharp leathery scale-like leaves overlapping like roof tiles — gives the tree its dramatic silhouette and its English common name. The name “monkey puzzle” was a Victorian-era reference to the supposed difficulty a monkey would have climbing the spiny branches.

Trees grow slowly but very long-lived; documented individuals exceed 1,000 years old.

The species produces large seeds (piñones) — much larger than typical pine nuts, comparable in size to small chestnuts. The seeds are nutritious, with a high carbohydrate and protein content.

Cultural and historical

The Pehuenche (“pehuén people”) of the Chilean and Argentine Andes traditionally depended on monkey-puzzle seeds as a foundational dietary staple. The harvest (autumn) provided dried, stored seeds that supported communities through the southern winter. Spanish colonial sources describe the Pehuenche’s heavy reliance on the species, and continuing Mapuche-Pehuenche traditional use of piñones remains culturally important today.

The species is the national tree of Chile and is featured on the country’s official emblem in some heraldic uses. In 1976 Chile declared the species a “national monument,” protecting it from logging.

Conservation crisis

The species is now classified as Endangered on the IUCN Red List. Threats include:

• Climate change — warming and drying of the species’ Andean habitat
• Fire — major 2017 and 2022 wildfires destroyed substantial old-growth monkey-puzzle forest in southern Chile and Argentina
• Historical logging (since restricted but the damage persists)

The species’ extreme longevity and slow regeneration mean that even ended human pressures will leave decades or centuries of population recovery ahead.
