The Waipa Foundation is a non-profit organization which sponsors a program called ʻAina Ulu (in the Hawaiian language), funded by Kamehameha Schools.
Its programs grew out of community efforts to manage the ahupuaʻa of Waipa in the late 1980s.
[3] An ahupuaʻa is an ancient Hawaiian land division from mountains to the sea, often corresponding to a watershed district.
[4] The restoration project at Waipa focuses on human interactions with plants and land.
Some sites feature Polynesian introduction plants, such as Piper methysticum (Kawa) and Cordyline fruticosa (Ti).
