About Tasmanian Blue Gum
Tasmanian Blue Gum (Eucalyptus globulus) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to southeastern Australian moist forest and woodland; cultivated forestry context is a reconstruction. A government forestry ledger compiled in 1980 documents Eucalyptus globulus planted on Kauaʻi in 1931. Historical planting evidence only; current survival, naturalization, abundance, recruitment, and ecological effects remain unconfirmed. Public occurrence is island-level only.
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 50 plants under Eucalyptus globulus 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.
