About Silver wattle
Silver wattle (Acacia dealbata) is an introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to southeastern Australia and Tasmania, where it grows in forest, woodland, slopes and creek-side settings. The Kauaʻi evidence is a historical forestry planting ledger only; the scene is a botanical reconstruction rather than evidence of a surviving island population.
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 23,117 plants under Acacia decurrens var. dealbata across 18 entries dated 1928–1938. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
