About White Gum
White Gum (Eucalyptus alba) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to the Lesser Sunda Islands, New Guinea, and northern Australia in wet-tropical savanna woodland. A 1980 forestry ledger documents Kauaʻi planting in 1931, 1958; 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 290 plants under Eucalyptus alba across 2 entries dated 1931–1958. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
