About Oriental Trema
Oriental Trema (Trema orientale) is an introduced tree documented on Kauaʻi by Bishop Museum’s 2025 checklist and the 2026 Smithsonian checklist. Its checklist classification is naturalized; current extent is unassessed. Native across the tropical and subtropical Old World to Australia and a classic pioneer of forest gaps, landslides, roadsides, and other disturbed ground. Birds disperse its numerous small drupes. Bishop Museum and Smithsonian document naturalized Kauaʻi occurrence; current abundance and ecological effects are unmeasured.
