About Us

Our Vision

The ahupuaʻa concept is a global example of a thriving and resilient social-ecological
community. The biocultural integrity of the ahupuaʻa of Heʻeia is restored to a state of
ʻāina momona and is a legacy for future generations.

Our Mission

To practice and promote stewardship through Native Hawaiian philosophies and values. Our efforts are supported by Indigenous knowledge, innovative research, education, and training that nourishes healthy and resilient ecosystems, economies, and communities.

Our Place

The He‘eia ahupua‘a is located in Ka-waha-o-ka-manō (commonly referred to as Kāne‘ohe Bay) within the Ko‘olaupoko region on the northeastern or windward shore of the island of O‘ahu. Heʻeia ahupuaʻa extends from the ridge of the Koʻolau mountains to the reef, encompassing areas for sustainable management. Kāne‘ohe Bay is the largest sheltered body of water in the Hawaiian Islands, with a total surface area of 18 square miles (11,000 acres).

 


He‘eia National Estuarine Research Reserve lies within the Heʻeia ahupuaʻa and encompasses 1,385 acres of unique and diverse upland, wetland, stream, estuarine, coastal, and marine habitats within the He‘eia ahupua‘a. It encompasses He‘eia State Park to the north, He‘eia Fishpond in the center, the wetlands of Hoi to the west and south, Moku o Lo‘e (Coconut Island) to the east, and a large expanse of marine waters with patch and fringing reefs.  

Reserve lands support wildlife, including:

  • federally endangered ʻAe‘o (Hawaiian stilt), ʻAlae ‘ula (moorhen), and ʻŌpe‘ape‘a (hoary bat)
  • bio-cultural keystone species such as Kalo (taro) and ‘Anae (Hawaiian striped mullet)

The biodiversity of the Reserve and intertwined suite of ecosystem services face threats from invasive species, soil erosion, sedimentation, non-point source pollution, and ocean recreational activities.  Ocean warming and acidification, sea level rise, changing rainfall patterns, and extreme weather associated with climate change will have an increasing impact on the Reserve and surrounding community.
