About White Ash
White Ash (Fraxinus americana) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to eastern Canada through the central and eastern United States in temperate upland hardwood forest. A 1980 forestry ledger documents Kauaʻi planting within the 1910–1960 forestry program; no species-specific year is available from the reviewed index; 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 26,864 plants under Fraxinus americana across 12 entries dated 1928–1936. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact. A transcription error in the planting year was corrected against Skolmen (1980); the original value remains in the research register.
