About Brexia
Brexia (Brexia madagascariensis) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native from the western Indian Ocean islands to the East African coast; Plants of the World Online places it primarily in the seasonally dry tropical biome. Flora of Mozambique records it at 0–40 m elevation in coastal scrub, mangrove swamps and fringing forest close to the sea. These source habitats describe its native ecology and do not imply a particular present habitat on Kauaʻi.
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 9 plants under Brexia madagascariensis across 1 entries dated 1943. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
