About Northern kurrajong

Northern kurrajong (Brachychiton diversifolius) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native across northern Australia from Western Australia and the Northern Territory to northwestern Queensland in the seasonally dry tropical biome. It grows from sea level to about 650 m in open forest, and also occurs at the margins of monsoon and gallery forest; Western Australian records include red sandy, basaltic and limestone substrates, stony hills and river margins. Seasonal leaf loss is part of its native dry-season cycle.

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 91 plants under Brachychiton diversifolium across 1 entries dated 1927. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
