About Naio

Naio (Myoporum sandwicense) is endemic to the Hawaiian Islands and recorded on Kauaʻi. Low spreading shrub or erect shrub to small tree, occasionally reaching 20 m.

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.
