HUI O KOOLAUPOKO

Hui o Koʻolaupoko (HOK) is a community-based 501(c)(3) watershed management nonprofit founded in 2007 that works across the Koʻolaupoko region of Oʻahu (Makapuʻu to Kualoa) to improve water quality through ecosystem restoration, invasive species management, stormwater mitigation, and public education. HOK implements on-the-ground projects (native planting, invasive removal, rain gardens, low-impact retrofits) and technical assistance, and operates volunteer and education programs that engage residents, schools, and partner agencies. The organization reports sustained community engagement (over 20,000 volunteers and ~55,000 volunteer hours since 2009) and has acted as a local coordinator on urgent invasive-species responses in recent years. In 2023–2025 HOK expanded its role addressing the Oʻahu little fire ant threat—working as an on-the-ground liaison with residents, partner nonprofits, and government agencies—while continuing stormwater and watershed restoration projects such as residential rain garden programs, Windward Mall rain gardens, and other ecosystem restoration efforts in the Kailua/Waimanalo/Kāneʻohe Bay watersheds.
