The Pu’u Kukui watershed extends across Mauna Kāhālawai on Mauiʻs West side.  

This pristine area is a vital water source for Mauiʻs community and one of the wettest spots on earth.  The intact native Hawaiian forest at Pu‘u Kukui works as a natural sponge to capture the water used by the entire West Maui community.  It is home to plant and animal species that exist nowhere else in Hawai‘i, or anywhere else. 

A small crew of paid staff and volunteers has been working over the last 30 years to protect the native forests and stop the threats from invasive plants and animals.  Our long-term goal is to restore damaged lands and expand the native forest.
