About Mountain Blue Gum
Mountain Blue Gum (Eucalyptus deanei) 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 Queensland and eastern New South Wales in moist subtropical forest. A 1980 forestry ledger documents Kauaʻi planting in 1950; it does not establish current survival, reproduction, or naturalization.
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 123 plants under Eucalyptus deanei across 1 entries dated 1950. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
