NatureServe Conservation Status
Rounded Global Status Rank: G1 - Critically Imperiled
Reasons: Endemic to Kauai, Molokai, Lanai, Maui, and Hawaii. The species is possibly extirpated on Lanai, only a single tree is currently known on Kauai, and it is extremely rare on Molokai and Maui. The only large population remaining is on the Pohakuloa Training Area on Hawaii. The total number of individuals of this species appears to be under 500. The major threats are ungulates, alien plants, and fire.

Zanthoxylum hawaiiense
Zanthoxylum hawaiiense, commonly known Aʻe or Hawaiʻi pricklyash, is a species of flowering plant in the citrus family, Rutaceae, that is endemic to Hawaii. It can be found at elevations of 550–1,740 m (1,800–5,710 ft) in dry forests, where it grows on lava flows, and mixed mesic forests on the Island of Hawaiʻi, Maui, Molokaʻi, and Lānaʻi.[2] It is threatened by habitat loss.
