Learn & Revive Heʻeia Wetlands

by Kākoʻo ʻŌiwi

Disclaimer: This site is following COVID-19 protocols which are updated with the Hawaii State Department of Health and may restrict certain activities.

Historically, Heʻeia was one of the most productive wetlands on Oʻahu — a thriving agricutltural landscape, producing volumes of kalo, a nutrient-dense dietary staple for Hawaiians, while providing habitat for native plants, birds, and fish. 

Land use changes led to a proliferation of invasive species that displaced native flora and fauna and disrupted the natural flow of water. Kākoʻo ʻŌiwi, a non-profit caring and restoring the nearly 405 acres of the Heʻeia wetland is restoring the wetland through Native Hawaiian management practices so that not only native species thrive in this area once again, but the community as well.
