Find Yourself On A Path To The Sea

Invaders have dug a stronghold on the shores of the Windward Coast, and threaten to hide traditional routes to the sea. Invasive plant species that found their ways to the streams, valleys, and estuaries of the Hawaiian Islands are encroaching on the natural irrigation routes, leaving them nearly impassible. Join Hui o Ko'olaupoko (HOK) to gain an understanding of Hawaii's unique ecosystems and what can be done to protect and restore them. At the breathtaking He'eia State Park, you can help to remove invasive species from the He'eia Estuary and replace them with Hawaiian native plants which aid in erosion control, filtration of stormwater runoff, and provide habitat for other native species.

Join us (nearly) every third Saturday to:

  • Secure the beauty and health of the Hawaiian Islands.
  • Restore habitat for fish and shorebirds.
  • Outplant native Hawaiian species
  • Take in awe-inspiring views.
  • Play in the mud.
  • Play & learn while you work.

Below is a brief description of the He╩╗eia Estuary Restoration Project and you can also find more information and pictures on our website.

He'eia Estuary Restoration:

Since the Spring of 2015, Hui o Ko’olaupoko has been working at the mouth of He’eia Stream to clear invasive mangrove and other non-native plants in an effort to restore stream flow, re-plant native plants and improve habitat for native aquatic species and shorebirds. The majority of invasive species removal was completed in under one year and the re-planting of native species began in February 2016.

Volunteers will be involved in clearing invasive plant species from the stream and shoreline area using small hand tools and hand pulling small weeds as we work to open and create areas to outplant native species. We will wrap up this service event with a short walk on the private He’eia Fish Pond wall to hear about its historical significance and how efforts to restore the fish pond are directly linked to the HOK project and other projects in the ahupua’a (valley).

Mission Statement

Protecting ocean health by restoring the aina: mauka to makai.


The mission of Hui o Koolaupoko is to protect ocean health by restoring the aina: mauka to makai.

Throughout the Koolaupoko moku (Makapuu to Kualoa) in Windward Oahu, land-based pollution is a leading threat to ocean health and resources. Hui o Koolaupoko (HOK) addresses these problems by being a leader in community-based watershed management; working with communities to improve water quality through ecosystem restoration, implementing low-impact retrofits (LIR), reducing non-point source pollution and developing education, outreach and volunteer programs for all ages.

Along with HOK’s restoration work in Koolaupoko, the organization provides services including technical consultation, restoration design, trainings and watershed restoration capacity building throughout Oahu and the State of Hawaii.
