About Smooth-barked apple
Smooth-barked apple (Angophora costata) is an introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival.
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 558 plants under Angophora costata across 1 entries dated 1941. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
