NatureServe Conservation Status
Rounded Global Status Rank: GH - Possibly Extinct
Reasons: Endemic to the island of Hawaii. This species is usually found at inhabited or abandoned Hawaiian coastal settlements, and less frequently inland. It appears that most, if not all, of these trees are remnants of Hawaiian plantings, and are not naturally occurring. These remaining trees are threatened by rats that are known to eat Pritchardia fruits, and by coastal development.

Pritchardia affinis
Pritchardia affinis is a species of palm tree that is endemic to the Hawaiian Islands. Wild populations currently exist on the leeward side of the Island of Hawaiʻi. It was most likely cultivated by Native Hawaiians, so its exact native range is uncertain. P. affinis reaches a height of 10–25 m (33–82 ft).[3] It is threatened by rats and pigs, which damage the trees. It is a federally listed endangered species of the United States. Its fruit was reportedly the preferred food of the now-extinct Ula-ai-hawane--a niche that has been seemingly filled by the introduced Lavender Waxbill.
