Kauaʻi evidence
Taxonomy, nativity, island-level occurrence, growth form, names, and source conservation assessments are documented in the 2026 census audit. Broader ecology and conservation recommendations still require claim-level source review. Generated imagery is not occurrence evidence. The 1918–1959 Kauaʻi reforestation working register records 1,498 plants under Myoporum sandwicense across 1 entries dated 1940. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.

Kauaʻi occurrence and status
- Kauaʻi occurrence
- Recorded on Kauaʻi
- Origin
- Endemic
- Conservation status
- Smithsonian checklist assessment: Apparently Secure; U.S. source status: No Status
- Evidence date
- 2026-10-05
- Evidence limits
- Island-level occurrence is retained; finer locality is intentionally withheld. Growth-form tags describe the taxon across its range, not a measured Kauaʻi population. Checklist source statuses are not a new legal-status determination. Nativity follows the current Hawaiian census and Bishop Museum treatment of the Hawaiian taxa as endemic. Broader treatments include Tonga; Bishop Museum treats that plant as Myoporum wilderi. The taxonomic disagreement is retained.
