Open this record in the interactive AtlasAbout Looking-glass Mangrove
Looking-glass Mangrove (Heritiera littoralis) is an introduced tree treated as naturalized on Kauaʻi by Bishop Museum’s 2025 checklist and the 2026 Smithsonian checklist. Current extent is unassessed. Native to mangrove, coastal swamp, and lowland wet tropical forest from eastern Africa through southern and southeastern Asia to the western Pacific. On Kauaʻi it is checklist-documented as naturalized at island scale; present abundance and ecological effects are not quantified.
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.
