About Kauaʻi Pricklyash
Kauaʻi Pricklyash (Zanthoxylum kauaense) is endemic to the Hawaiian Islands and recorded on Kauaʻi. Small to medium tree usually 3–15 m tall, with brown to gray-brown bark and hairless or finely hairy new growth.
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.

- 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.
