About Black Mulberry
Black Mulberry (Morus nigra) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to southwestern Asia and adjoining temperate regions, with a long history of cultivation obscuring its precise wild range. 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 3,407 plants under Morus nigra across 3 entries dated 1937–1944. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
