About Jackfruit
Jackfruit (Artocarpus heterophyllus) is a post-contact introduced tree documented on Kauaʻi through cultivation records. Native to southwestern India and characteristic of humid tropical forest and long-established agroforestry systems. It is monoecious and cauliflorous; tiny insects including gall midges are associated with pollination, while large fleshy fruits and seeds are dispersed chiefly through human cultivation and by fruit-eating animals where accessible. Historical forestry records document planting on Kauaʻi; these records do not establish present survival 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 58 plants under Artocarpus heterophyllus across 1 entries dated 1938. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
