Kauaʻi evidence
Taxonomic identity, tree form, diagnostic morphology and island occurrence use the linked reviewed sources. Historical planting, cultivation, naturalization and invasive status are separate. Generated imagery is not occurrence evidence. The 1918–1959 Kauaʻi reforestation working register records 152 plants under Araucaria columnaris across 1 entries dated 1927. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
