About Forest red gum
Forest red gum (Eucalyptus tereticornis) is an introduced tree treated as naturalized on Kauaʻi by Bishop Museum’s 2025 checklist and the 2026 Smithsonian checklist. Current extent is unassessed. An Australian tree of seasonally dry tropical to subtropical forests and woodlands. The Bishop 2025 note questions Oʻahu, Maui, and Hawaiʻi records only; Kauaʻi remains an unqualified naturalized checklist record.
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 239 plants under Eucalyptus tereticornis across 1 entries dated 1931. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
